A total of 11,495 complaints were received by the D.O.T. with nearly a third involving flight problems such as flight delays and cancellations…
A troubling new reality for those flying is getting bumped from a flight where they already have a ticket. Last year, the number of denied boardings for oversold flights increased as airlines limited capacity and aggressively worked to increase their load factors.
“There are simply fewer free seats to place bumped passengers,” said Headley. “So you have a passenger saying, ‘Why me? Why am I the one person on this flight getting bumped when I bought a ticket like everyone else?'” | aerospace |

Sunday Aircraft Cheesecake (SAAB 37 Viggen)
(Incidentally, the word viggen means thunderbolt, particularly one issued from Thor's warhammer, Mjölner).
Sunday Aircraft Cheesecake (F-14 Tomcat)
After more than 30 years of distinguished service to the US Navy, the last two squadrons of F-14 Tomcats ended their final combat deployments about two weeks ago. A couple of nice articles about this milestone event can be found here and here.
Check out this nice tribute video, too:
Q: Why is this awesome war machine being retired without (according to many) an adequate replacement (the Super Hornet lacks the range and power of the F-14)?
A: Maintenance expenses and age (the two are related).
Check out this comment from a former jet mechanic, giving a hint of the issues he (and other mechs) would face. Note also his love for the plane:

As a retired Jet Mech. (AD1), last serving with the Tophatters of VF-14 at NAS Oceana in 1995, I am left with a sentimental lump in my throat as an era of Naval Aviation comes to a close. As labor intensive as they were, it was a proud sight and feeling to witness the awesome vibration and thunder on the TF-30 turbofans as the throttles were advanced to zone five behind the JBD's. Call it a labor of love I supose but intense it was. It was a nightmare for the hazmat P.O. trying to keep up with the constant mess of leaking hydraulic fluid and JP-5 under the engines forward fixed cowlings. As physics would prove, anything that was that fast and could turn on a dime and endured massive G- forces would naturally leak fluid from somewhere. A chapter in Naval Aviation to be admired and cherished for many years to come. Good-bye my friend!!
Sunday Aircraft Cheesecake (F-22 Raptor)

Sunday Aircraft Cheesecake (B-47 Stratojet)
America's first swept-wing multi-engine jet bomber, the Boeing B-47 Stratojet:
Sunday Aircraft Cheesecake (XFV-1)
We return, briefly perhaps, after an extended hiatus...
The unconventional, tail-sitting Lockheed XFV-1 was the prototype for a proposed U.S. Navy vertical take-off and landing (VTOL) point-defense interceptor. Designed to take off vertically, transition into conventional wings-level flight and then transition back to the vertical for landing, the airplane was powered by a 5,850 horsepower turboprop engine driving a pair of huge, three-bladed contra-rotating propellers. Fitted with a temporary undercarriage, the XFV-1 was first flown in a conventional mode at Edwards on June 16, 1954. Although, while in flight, it did demonstrate successful transitions from conventional into the vertical mode and back, its engine lacked sufficient power to guarantee safe VTOL operations and the whole concept of tail-sitting aircraft was soon abandoned in favor of designs employing vectored jet thrust.

RIP, Marta Bohn-Meyer
Test pilot Marta Bohn-Meyer died last week in a crash of an aerobatic plane in Oklahoma.
Sadly ironic that she would die in a little single-engine prop plane after a career that included flying one of NASA's SR-71s at three times the speed of sound in high altitude tests at Dryden Flight Research Center in California.
Seventh Moscow International Air Show
I know that I have been remiss in posting the regular Sunday Aircraft Cheesecake around here, and for that I apologize.
I hope to get some decent images from the reports on the just-opened MAKS 2005 (the seventh annual International Aviation and Space Salon in Moscow).
Just one little pic so far -- the new MiG29OVT, the first twin engine jet fighter to employ multiaxis (versus 2D) thrust vectoring. At least according to this article, from which I grabbed the pic.
Sunday Aircraft Cheesecake (The Red Arrows)
As a tribute to our good friends in the UK who have suffered much this week, this week's cheesecake serving features some images of the Royal Air Force's Red Arrows aerobatic team:
Sunday Aircraft Cheesecake (B-36 Peacemaker)
Made only in Texas.
Part prop, part jet.
The B-36 Peacemaker:
For an idea of just how frickin' big this plane was, check out this side-by-side photo, which makes the B-29 bomber look like a toy:
(Image found here).
Neat story describing the experience of a low flyover.
So far, it's just a prototype technology demonstrator, but it has already achieved a milestone for rotary-wing craft: a mu of 1 for the first time in history (achieved on June 17, 2005).
Yeah, I didn't have the faintest clue what that meant, either, but read more about it here and keep your eyes peeled for these very attractive rotorcraft.
Sunday Aircraft Cheesecake (Ki-61 Tony)
The Kawasaki Ki-61 Tony:
(Image from Stof's "Virtual Flying" Page).
If you read the linked pages above, you'll see why it's no accident that this plane resembles the German Me-109.
Sunday Aircraft Cheesecake (Me 262)
The first jet fighter in history to see battle, the Messerschmitt Me-262:
The Me-262 Project is a private effort to create reproductions of this historic and beautiful aircraft. Interesting to me, much of the initial work was done in Fort Worth, Texas, just about an hour and a half southwest of here. Here's a picture of one of their creations in flight:
Update: The Country Pundit wrote a nice piece about this airplane, with more detail and history than I typically use in these kinds of posts.
Sunday Aircraft Cheesecake (De Havilland Buffalo)
I apologize for the approximately month-long hiatus in this feature. Let's kick it off again with a bit of an odd duck suggested by Alan Brain.
We start with the conventional, versatile cargo/transport airplane, the De Havilland DHC5 Buffalo. Here is a typical shot of the aircraft:
(Image from http://www.xdh.ca/DHC_Aircraft/DHC-5/dhc-5.html).
In the 1970s, NASA contracted with Boeing to modify the DHC5 to investigate new technologies for STOL aircraft.
Boeing rebuilt the plane with new avionics, new wings and tail, and a quartet of jet engines mounted above the wing to generate "upper surface blowing" in order to increase lift. The plane made its maiden flight at Boeing's Seattle plant in 1978, then flew to Ames for continued flight tests. The short takeoffs and quiet operations of the aircraft yielded much information for application in both civil and military design. One intriguing series of tests led to a successful landing and takeoff from an aircraft carrier-- the first four-engine jet plane to accomplish this feat.
The result was quite interesting:
Full-sized, restricted, and watermarked photos available here.
Sunday Aircraft Cheesecake (A-10 Thunderbolt a/k/a "Warthog")
This week, we feature the Fairchild Republic A-10 Thunderbolt (sometimes known as the "Warthog"). One of my long-time favorites, this craft simultaneously straddles the aesthestics of WWII bombers and modern jets. Though named after the WWII US P-47 fighter, this flying tank-killer is much closer in spirit to the WWII Soviet IL-2/IL-10 Shturmovik.
Sunday Aircraft Cheesecake (Rutan Aircraft ARES)
I just recently discovered that Rutan Aircraft Factory (Burt Rutan's pre-Scaled Composites company) designed, built, and flew a ground attack aircraft similar in mission to the USAF's A-10 Warthog, the ARES (Agile Responsive Effective Support). First designed in 1981 as a turboprop in response to an Army request for a low cost battlefield attack aircraft, the ARES was built in 1986 as a turbojet. Similar to the A-10, the ARES is literally built around a gatling gun, in this case the GAU-12/U 25mm gun. Check out the size of the gun port on the fore starboard side of the plane:
Despite meeting all requirements, the plane never found a purchaser and remains a prototype. Find much more information about it at the Scaled Composites website.
More Aircraft Cheesecake
In case you haven't gotten enough, this page has a great collection of tasty photos from the 2003 Chicago Air and Water Show. My favorites are the B-1 buzzing an apartment building and the "heritage" photo of the P-51 with the A-10. Good stuff.
Sunday Aircraft Cheesecake (Antonov An-225)
Note the many wheels along the rear bottom of the plane, much like the Arado Ar 232:
To get an idea of just how big this plane is, take a look at how small the Russian Buran shuttle is in comparison:
The Buran is about the same size as the US Shuttle orbiter, which takes up quite a bit more space on the back of a Boeing 747.

Art of Industrial Design
Virginia Postrel points to a fascinating site that mines old patents for examples of striking industrial design. They have a "what's new" blog, too, which I have added to the "Between Planets" section of the blogroll.
I also found a mother lode of incredible early aircraft designs via the site.
Some examples in the extended entry:
Sunday Aircraft Cheesecake (F-18 Hornet)
The F-18 Hornet is simply one of the most beautiful airplanes currently flying:
Sunday Aircraft Cheesecake (Boeing 377 Stratocruiser)
This week's serving of cheesecake features a bizarre-looking civilian transport/cargo aircraft the Boeing 377 Stratocruiser, which was derived from a military transport, which itself was derived from the B-29 bomber of WWII:
In the 1960s, some of the 377s were modified to carry the third stage of the Saturn V moon rockets (the Saturn IVB) from its assembly plant in California to Florida. These variants were dubbed the Pregnant Guppy and the Super Guppy:
(Much information on these bizarre planes can be found at this great page. And according to this NASA page, Airbus manufactured a Super Guppy recently and traded it to NASA for transport of space station components!)
Sunday Aircraft Cheesecake (Kalinin K-7)
This week's serving of cheesecake is the Kalinin K-7. This bomber hails from the early 1930s, and foreshadows the heavy bombers that would play such a large role in WWII less than a decade in the future. Looking at its contemporaries, this plane is really a stunning bit of modernism. Unfortunately there aren't many pictures available since the prototype crashed and no others were ever produced. Enjoy:
Sunday Aircraft Cheesecake (F2H Banshee)
Here's an archival photo of the plane in flight (found here):
Sunday Aircraft Cheesecake
Could there be any doubt this week?
Burt Rutan's Global Flyer, piloted by Steve Fossett in his record-breaking flight this past week:
(Both images from Virgin Atlantic Global Flyer multimedia site).
Also, this little-known plane from very early in Rutan's career (courtesy of a family friend), the Rutan B-17X:
(Note for the clue-impaired: it's a photoshop).
Way to Go (and Go and Go), Fossett!
Steve Fossett successfully circumnavigated the globe in a single-engine jet airplane on a single load of fuel. Solo.
Sunday Aircraft Cheesecake (WF-2/E1-B Tracer)
This week's aircraft cheesecake continues with the flying saucer theme introduced last week. The Grumman WF-2 ("Willy Fudd") (later redesignated the E1-B Tracer) was the US Navy's first carrier-borne early warning aircraft:
Sunday Aircraft Cheesecake (Flying Flapjack)
This week's airplane comes courtesy of Alan Brain's Yamato Sashimi article, which introduced me to the "Flying Flapjack" for the first time. Without further ado, the Chance Vought V-173/XF5U "Flying Flapjack:"
More info here, too.
Sunday Aircraft Cheesecake (F-16 Fighting Falcon)
I have long loved the lethal, lovely lines of the F-16 Fighting Falcon:
Sunday Aircraft Cheesecake (MiG 25 Foxbat)
I know it's a stretch, but I'm trying to make tonight's cheesecake relevant to the Super Bowl winner.
It would have been relatively easy if Philadelphia had won, since I could have posted an F-15 Eagle. But no aircraft seems to have been nicknamed the "Patriot" so the link between the plane and team nicknames has to be more tenuous.
Here goes: the Patriots' home field is in Foxboro, Massachusetts. "Foxbat" is vaguely reminiscent of "Foxboro." Thus, as a tribute to an American football team named the Patriots, I give you a Soviet-era fighter, the MiG-25 Foxbat:
Sunday Aircraft Cheesecake (Arado Ar 232)
It came in two variants, the Ar 232A, which was powered by 2 BMW 801 engines, and the Ar 232 B, powered by 4 BMW-Bramo 323 R-2 engines. The plane had a normal "tricycle" landing gear for landings on well-paved airfields. However, the landing gear could be "broken," to lower the plane onto the 22 belly wheels, from which the plane derived its nickname. This allowed the cargo ramp to be extended at a smaller angle from the rear of the cargo bay. The belly wheels also allowed for additional support when landing on rough surfaces. Amazingly, even when fully loaded with a 16-metric-ton cargo, the plane could take off in 200 meters (shorter with rocket-assisted takeoff).
Here's the "A" in flight:
A nice shot of the "Millipede" landing gear on an "A":
And a different view of the landing gear on a "B":
Sunday Aircraft Cheesecake (Harrier)
This week's serving is the V/STOL (vertical/short takeoff and landing) attack aircraft, the Harrier. The aircraft has an interesting developmental history, with inputs from France (original engine design), West Germany, the UK and US (explained in more detail here):
Sunday Aircraft Cheesecake (Tu-20 "Bear")
Sunday Aircraft Cheesecake (Blohm und Voss BV 141)
This week's cheesecake is a bit of an ugly duckling. Perhaps one of the most asymmetrical military aircraft ever flown, the Blohm und Voss B.V. 141:
Sunday Aircraft Cheesecake (P/F-82 Twin Mustang)
This week's entry is the F-82 Twin Mustang, essentially two P-51 bodies sharing a single wing:
Sunday Aircraft Cheesecake (M-50 Bounder)
Another Russian plane this week, the Myasischev M-50 Bounder:
According to the FAS link above, little is known about this plane's performance, though one referenced commenter noted that the M-50 was "an outstanding failure which revealed an embarassing lack of understanding of the problems of high-speed flight."
(Be sure to check out the other exhibits at AXLs Plane Gallery, where I found these images).
Sunday Aircraft Cheesecake (Su-34)
Behold the Sukhoi Su-34 "Fullback:"
Sunday Aircraft Cheesecake (XB-70)
This week's cheesecake helping is the XB-70 Valkyrie:
Sunday Aircraft Cheesecake (X-5)
This week's serving is yet another X-plane, the Bell X-5. This was the first plane to have a variable-angle wing, making it the forebear of the F-111, F-14, and B-1 aircraft (which will likely make future appearances here):
Sunday Aircraft Cheesecake (X-3)
This week's featured aircraft is the aptly-named Douglas X-3 Stiletto:
Sunday Aircraft Cheesecake (P-61)
This week's cheesecake serving is the Northrop P-61 Black Widow Night Fighter:
Sunday Aircraft Cheesecake (P-38)
One of my favorite aircraft of all time, the P-38 Lightning:
I ran across this neat Japanese site detailing the assembly of a remote-controlled scale P-38 while looking for this week's serving of cheesecake.
Sunday Aircraft Cheesecake (B-58)
Sunday Aircraft Cheesecake (DH-4)
This week we feature yet another De Havilland aircraft, the DH-4.
I saw a plane very similar to this one, the Boeing 40B-2, at the Chicago Museum of Science and Industry last week. The exhibit was accompanied by the following letter from Leonard B. Hyde-Pearson, an airmail pilot who died in a plane crash in a De Havilland mail plane on March 7, 1924:
"To Be Opened Only After My Death:
Capt. Leonard Brooke Hyde-Pearson, USAMS
"My Beloved Brother Pilots and Pals"
I go west, but with cheerful heart.
I hope whatever small sacrifice I have made
May be of some use to the cause.
When we fly we are fools, they say.
When we are dead, weren't half-bad fellows.
But everyone in this wonderful aviation service
Is doing the world far more good than the public can appreciate.
We risk our necks; we give our lives;
We perfect a service for the benefit of the world at large.
They, mind you, are the ones who call us fools.
But stick to it, boys. I'm still very much with you all.
See you all again.
It's always risky to open a new frontier. The next time you buckle into a commercial jetliner, remember these words of Captain Hyde-Pearson, since you owe safe, routine, air travel in large part to pioneers like him.
Sunday Aircraft Cheesecake (Mosquito)
Quite an incredible aircraft. As a result of its molded plywood and balsa wood construction, this twin-engine plane, which was originally specified as a bomber, became one of the fastest, longest-range multirole fighters of World War II.
It packed quite a punch: in its typical night-fighter package, it carried four 20mm cannon in a belly mount and four .303 machine guns in the nose.
Sunday Aircraft Cheesecake (Sea Vixen)
This week's airplane is the De Havilland Sea Vixen:
As will become apparent in future servings of aircraft cheesecake, I find the twin-boom tail an attractive feature on airplanes.
Sunday Aircraft Cheesecake (F-89)
This week's entry is much more of an "interesting" than a "beautiful" plane. In fact, the plane is pretty homely but attractive in that odd way that only straight-wing jet fighters can be. The F-89 Scorpion:
This fighter, aside from having an interesting profile and decent performance for a non-swept-wing jet, was the USAF's first interceptor to be armed with air-to-air nuclear rockets.
You heard me right. In the 1950s, the Air Force developed an air-to-air missile (the AIR-2 Genie) with a nuclear warhead designed to take out an entire squadron of Russian bombers at a time.
The F-89 carries the distinction of being the first (and only) plane ever to fire and detonate a nuclear-armed air-to-air missile, on 19 July 1957. I've looked for pictures of the test-firing but can't find any.
Sunday Aircraft Cheesecake (F4U Corsair)
This week's entry is the Chance Vought F4U Corsair:
I remember this plane as the "star" of the TV show Baa Baa Black Sheep, which I enjoyed as an eight-year old boy. The show was based on the experiences of American WWII ace, Gregory "Pappy" Boyington, related further in his autobiography.
This page has some links to the F4U Corsair's training films.
Sunday Aircraft Cheesecake (Su-47/S37 Berkut)
I love airplanes. I especially love military aircraft, and even moreso unique-looking military aircraft. For the next couple of weeks, I will try to highlight an aircraft that strikes my fancy. It may or may not become a regular feature.
This week's entry is the Sukhoi Su-47/S37 Berkut:
Enjoy the pic, and let me know if you have a favorite aircraft you would like to see featured.
Aircraft Aesthetics Revisited
But we can find common ground in our admiration of the B-25 Mitchell. I especially like the B-25 "G" and "H" variants, with the nose-mounted 75mm cannon (a predecessor of the AC-47 and AC-130 gunships).
Aviation historian Martin Caidin wrote an entertaining, if fictionalized, history of the B-25 gunship in Whip, which I read many times in my teen years.
Another of my favorites -- developed but not flown in WWII -- is the B-36 Peacemaker.
Air Show Pics
My favorite is the side-by-side flyby photo of the A-10 Warthog and the P-51 Mustang.
100 Years of Flight
Many of the bloggers I follow on a daily basis have appropriate words to commemorate the monumental accomplishment of the Wright brothers. Naturally, Rand Simberg has been busy, with articles up at Tech Central Station and National Review in addition to his own blog entry.
Rocket Man Mark Oakley discusses Rand Simberg’s "Airplane Scientist" article from TCS, and posts an opinion on why we have not advanced as far in space during the 42 years since the first manned spaceflight as we did in aviation during the 42 years
after Kitty Hawk.
Tim Sandefur, who has a sweet picture of an SR-71 and a copy of one of my favorite poems, High Flight, contrasts the triumph of the free, entrepreneurial Wright Brothers with the failure of the government-funded Samuel Pierpont Langley (a point also made by Rand Simberg in his several articles above).
Since Tim got High Flight up first, I'll have to resort to quoting some poetic prose from one of my favorite books:
Throttle forward again and the airplane swings into take-off position on runway two eight. The concrete is wide and long. The painted white stripe along its center is held at one end by my nosewheel, at the invisible other end by the tough nylon webbing of the overrun barrier. A twin row of white edge lights converges in the black distance ahead, pointing the way. The throttle moves now, under my left glove, all the way forward; until the radium-caked tachometer needle covers the line marked 100 percent, until the tailpipe temperature is up by the short red arc on the dial that means 642 degrees centigrade, until each pointer on each dial of the red-soaked instrument panel agrees with what we are to do, until I say to myself, as I say every time, Here we go. I release the brakes.
There is no instant rush of speed, no head forced against the headrest. I feel only a gentle push at my back. The stripe of the runway unrolls, lazily at first, beneath the nosewheel. Crackling thunder twists and blasts and tumbles behind me, and, slowly, I see the runway lights begin to blur at the side of the concrete and the airspeed needle lifts to cover 50 knots, to cover 80 knots, to cover
120 knots (go-no-go speed checks OK) and between the two white rows of blur I see the barrier waiting in the darkness at the end of the runway and the control stick tilts easily back in my right glove and the airspeed needle is covering 160 knots and the nosewheel lifts from the concrete and the main wheels follow a half-second later and there is nothing in the world but me and an airplane alive and together and the cool wind lifts us to its heart and we are one with the wind and one with the dark sky and the stars ahead and the barrier is a forgotten dwindling blur behind and the wheels swing up to tuck themselves away in my seamless aluminum skin and the airspeed is up to one nine zero and flap lever forward and airspeed two two zero and I am in my element and I am flying. I am flying.
Apologies Accepted, Tim
De Gustibus Non Disputandum Est
Nothing with propellers can qualify as a cool looking plane? I know it's ridiculous to argue matters of taste, but allow me to enter into evidence a few more exhibits of "cool" propeller planes:
Don't get me wrong, I love jet and rocket planes, too, but I hate to see piston-engined, propeller-driven craft unjustly denigrated. (BTW, if you want to learn how to fly any of the old WWII warbirds, watch the training films here).
Ride [Well, Flight] of the Valkyrie
Not exactly sexy, but one of the coolest-looking planes ever has to be the Peacemaker.
Fun Aviation Story
(Setup: sometime in the 1960s, some Marine F-4 Phantom pilots, to escape a hurricane on the Gulf Coast, are temporarily stationed inland at an Air Force base and proceed to brag about how they are flying the fastest planes in the world and generally ragging on the "low slow" bomber pilots. Hint: the "bombers" these particular Air Force pilots were flying were B-58 Hustlers).
Of course the Marines should have just gone double-or-nothing whether the Hustler pilots could land on a pitching carrier deck in the dark. | aerospace |

The amazing National Air and Space Museum Steven F. Udvar-Hazy Center in Virginia wows visitors with some of the Smithsonian's largest and most impressive aircraft. Housed in two giant hangars, the collection includes a Space Shuttle, Blackhawk SR-17, Concorde, and other huge aircraft. It's an impressive space that is a lot of fun to explore for all ages.
The most popular museum in Virginia, the Udvar-Hazy Center is an excellent year-round destination and is one of the top 10 attractions in Northern Virginia. When the weather turns too hot, rainy, or cold outside, this is one of our favorite indoor activities in Northern VA.
Disclosure: This article may contain affiliate links. We will make a small commission from these links if you order something, at no additional cost to you.
The Udvar-Hazy Center, one of the most visited museums in the US, is a fantastic place to bring out-of-town visitors. Fortunately, the museum is so huge that crowds won't be a problem no matter when you visit. In addition, admission is free (parking is $15) so it's a great budget day trip close to Washington DC.
Things to Do at the Air and Space Museum Udvar-Hazy Center in Virginia
The Udvar-Hazy Center is huge so you can easily spend a full day exploring the entire collection, watching a movie in the IMAX theater, and trying some of the interactive exhibits. If you only have a few hours, focus on some of the highlights of the Udvar-Hazy Center collection (list below).
Whether you spend a few hours or a full day, prepare for walking. The museum collection is spread out across three large hangars with concrete floors.
Here are the top 9 things to see at the Udvar-Hazy Center, according to the Smithsonian:
- Lockheed SR-71 Blackbird: the world's fastest jet-propelled aircraft.
- Space Shuttle Discovery: spent 365 days in space during 39 Earth-orbital missions.
- Boeing B-29 Superfortress “Enola Gay”: dropped the first atomic bomb on Hiroshima in 1945.
- Air France Concorde: the first supersonic airline which flew at twice the speed of sound and could cross the Atlantic in just 4 hours.
- Bücker Jungmeister: an aerobatic flyer popular in shows in Europe and the US.
- Boeing 367-80: aka the Dash 80, was developed into the first US jetliner, the 707.
- Marauder B-25 B-26 “Flak-Bait”: survived more World War II operational air missions over Europe than any other US aircraft.
- Boeing 307 Stratoliner Clipper “Flying Cloud”: a beautiful 33-passenger aircraft flown by Pan Am.
- Grumman F-14D Tomcat: a supersonic strike fighter.
Of course, interests vary and the whole collection is worth checking out. Read on for things to do and see at the Air and Space Udvar-Hazy Center.
Explore the Udvar-Hazy Smithsonian Collection
Like at most museums, the main activity for visitors is to walk around and explore the exhibits. At the Udvar-Hazy Center, exhibits are spread across three levels throughout two vast hangars. You can easily spend hours slowly working your way through the whole collection.
Several new aircraft are added to the displays and more undergo restoration every year. Visitors can now see the Mercury Freedom 7 capsule which carried Alan Shepard into space 50 years ago.
For the first time, visitors can take a close-up look at a U.S. Navy Blue Angels Hornet. Plus, sci-fi fans will be excited to see the addition of a full-sized X-wing Starfighter that appeared in Stars Wars: The Rise of Skywalker.
If time or attention spans are short, we suggest focusing on a few highlights. After you pass security, go straight to the rail for your first look at the huge Boeing Aviation Hangar. Ahead of you is the spooky-looking Blackbird SR-71, the world's fastest jet-propelled aircraft. and behind it, the Space Shuttle Discovery.
Our preferred route from the overlook is to head downstairs and straight ahead to the McDonnell Space Hangar. Here you can get a close-up look at the Space Shuttle Discovery which flew the most Earth-orbital miles during its 27 years in service. The Discovery carried 184 crew members into space including astronaut John Glenn who returned to space at age 77.
Other spacecraft and space artifacts around Discovery cover the Mercury, Gemini, and Apollo missions. For example, a Mobile Quarantine Facility was used by astronauts Buzz Aldrin, Neil Armstrong, and Michael Collins after their trip to the moon.
Standing next to the Space Shuttle is truly inspiring. Take time to walk around and take in the scale of the engines. Also, notice the complex tiled exterior and the visible scars from its many missions in space.
Around the shuttle, additional artifacts and displays share details about the human journey into space.
After the McDonnell Space Hangar, we like to explore general aviation displays on the first floor. Finally, we head up to the catwalk for an amazing view and additional exhibits.
The variety and scale of the aircraft—from the shiny Clipper Flying Cloud, to the streamlined Concorde, to the historic Enola Gay—always impresses. The Boeing Aviation Hangar is three football fields long so allow plenty of time to see the full collection.
If you have more time or members of your group have specific interests, there is plenty more to see throughout all three levels of the hangar.
Catch an IMAX Movie or a Simulation Ride
The Udvar-Hazy Center includes an Airbus IMAX Theater with a five-story high screen and several 3D movies to choose from. Buy advance tickets online to ensure access to your favorite movie, or just see what's available when you arrive. There are also simulator rides on the main floor of the Boeing Hangar.

Near the IMAX theater entry, a short elevator ride takes visitors up to the Observation Tower. Level two explains the workings of the US Air Traffic Control system. On the top floor, enjoy excellent views of Dulles Airport and the surrounding countryside.
If your timing is good, you may see flights as they take off and land. Sometimes the flights pass directly above the tower, a dramatic sight.
Enjoy an Expert-led Tour or Special Event
Free docent-led tours are offered daily at 10:30 and 1:00. Often, aviation experts are on hand signing books and doing special presentations.
The museum hosts some fantastic special events throughout the year including a special Father's Day display. In addition, monthly Family Days focus on topics such as Women in Aviation. There's also a very popular Halloween trick-or-treating event every year on the Saturday before Halloween.
Tips for Your Visit to the Udvar-Hazy Center in Virginia
Admission to the Udvar-Hazy Center is free but parking is $15.00. If you arrive after 4:00 PM, parking is free, but the museum normally closes at 5:30 so your visit will be short.
There is a fun store where you can buy a real space blanket, space-inspired games, and gear. You can even buy an astronaut suit for the little ones.
Next door is a Shake Shack, the only restaurant at the museum, which serves a fast-casual menu of burgers, hot dogs, fries, shakes, and more. Outside food and drink are prohibited so Shake Shack is your only food and beverage option.
Remember, plan for a lot of walking! Wear comfortable shoes and bring a stroller for little ones. The huge hangars require a lot of walking on concrete floors. Strollers are allowed everywhere except the Observation Tower and the museum is wheelchair accessible.
The Smithsonian Air And Space Museum, Steven F. Udvar-Hazy Center is located at 14390 Air and Space Museum Parkway in Chantilly, Virginia. Visit the museum website for the latest updates on events and displays.
It is easier to reach the Udvar-Hazy Center in Virginia via public transportation now that the Silver Line Metro has been extended to Dulles Airport. From the airport, take the Fairfax Connecter No 983 bus one stop to the museum.
A Little Udvar-Hazy Center History
This gem in Smithsonian Institution's collection opened in 2003 at the south end of Dulles International Airport in Northern Virginia. The location met two key criteria for the project:
- it is within one hour's drive of the National Mall in Washington DC
- it offers sufficient open land and is adjacent to an airport. With access to nearby runways, new acquisitions can be brought to the display space.
In 2012, Space Shuttle Discovery was flown in, strapped atop a Boeing 747. Locals were treated to several flyovers in Washington DC and Northern Virginia before the plane landed at Dulles. Direct airport access makes it possible for the museum to bring in and house new large aircraft like the shuttle. This would be impossible in the National Mall location.
Steven F. Udvar-Hazy donated $65 million for the museum's construction, making this one of the few Smithsonian buildings created with private funds.
Since its opening, the National Air and Space Udvar-Hazy Center in Virginia has grown to an average of one million visitors a year. With its impressive scale and extensive collection, the museum makes a fun and interesting destination for locals and visitors in the Northern Virginia and Washington DC region. And it's the perfect place to beat the heat or escape the cold. | aerospace |

Back in August 2017 we reported on Bye Aerospace’s plans for its Sun Flyer 2 and Sun Flyer 4 all-electric trainer aircraft. The former is currently under development with plans for full FAA certification later this year.
In pursuit of that goal, last week Bye announced a formal partnership with Electric Power Systems (EPS) for the supply of the Sun Flyer 2’s energy storage systems. Under the contract, EPS will design and build the full storage system including battery modules, a battery management unit and power distribution systems for its Flight Demonstrator aircraft.
According to the pair, this demonstrator is scheduled for first flight tests some time in Q2 2018.
“We’re excited to work with Bye Aerospace on making the Sun Flyer the first all-electric airplane certified under the new FAA Part 23 regulations,” said EPS CEO Nathan Millecam.
The 2-seat model features a 100-kW motor, while the 4-seater Sun Flyer 4 has at least 130 kW of propulsion according to specifications listed by Bye Aerospace. The latter offers a 1,250 feet per minute best rate of climb, and speeds of up to 120 Knots.
The battery will reportedly offer four hours of flight time, although actual capacity is not listed in the aircraft specifications.
EPS however, is one of the standout players in the electric aviation space. In addition to Bye, the company is also working with NASA as part of its X-plane development programme. EPS’ work on the all-electric X57 aircraft includes the manufacture and supply of battery modules, the battery control computers, and the integrated assembly components for the aircraft.
Referencing the X-plane initiative, EPS’ VP of engineering and co-founder Randy Dunn noted: “EPS’s modular Battery Management System (BCC-701) and its aviation grade Energy Producing Ion Core (EPIC) battery modules enable NASA to meet its objectives of having a highly reliable custom high voltage battery that can be flown in 2017.”
The company says its system is ideal for the NASA project because its battery management system can be configured easily to fit multiple chemistry types, while maintaining the integrity of a DO311 design base. This enables the use of commercial cells that can be integrated into a large-scale battery.
Millecam added: “Our Energy Storage System leverages technology developed for NASA’s X57 platform, that enables our Battery Module to meet stringent FAA safety requirements around containment of cells in thermal runaway at a very light weight.”
The LA-headquartered company recently expanded to a new site in Logan, Utah, next to the Logan-Cache airport. | aerospace |

Bepi Colombo. by Johannes Benkhoff (ESA-ESTEC)
BepiColombo is a joint project between ESA and the Japanese Aerospace Exploration Agency (JAXA). The Mission consists of two orbiters, the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO). The mission was launched with an ARIANE V October 2018 and will arrive at Mercury in the second half of 2025. From their dedicated orbits the two spacecrafts will be studying the planet and its environment. The MPO scientific payload comprises eleven instruments/instrument packages; the MMO scientific payload consists of five instruments/instrument packages. Together, the scientific payload of both spacecraft will perform measurements to find clues to the origin and evolution of a planet close to its parent star. The Nominal Science Mission of BepiColombo will cover 1 terrestrial year and be divided into 2 six-month phases, tentatively called the global mapping and target mapping phases. The latest status of the BepiColombo mission will be given with special emphasis on the scientific return from already more than 3 years in cruise and 4 planetary flyby’s.

2003 Balloon CampaignCurrent weather conditions in Alice Springs
About Alice Springs
NIGHTGLOW prepared for a launch from Alice Springs, Australia on an ultra-long duration (ULD) "pumpkin" balloon, waiting for the instrument, balloon, and weather conditions to be right. The science team arrived in Alice Springs in late December 2002 and early January 2003. The balloon arrived on January 11. The science team assembled and tested the NIGHTGLOW instrument and readied it for the balloon launch.
NIGHTGLOW finally launched from Alice Springs, Australia on March 17, 2003 at 8:38 a.m. local time (March 16 at 6:08 p.m. EST). Unfortunately, the flight was terminated on March 17, 2003 at 8:07 p.m. local time (March 17 at 5:37 a.m. EST) due to pressure loss in the balloon.
Above are aerial photos of the landing site. The leftmost two photos are of the payload (NIGHTGLOW) in a small lake in the middle of the Outback. You can see its parachute lying at the edge of the lake. The photo on the right is of the ULD balloon on dry land near the lake.

The RB-50 was a modified version of the Boeing B-50 medium bomber, itself a much-improved development of the B-29 bomber of late-World War II vintage. The B-50s had been the main SAC medium bomber from the late 1940s until the new B-47 jet medium bomber entered the SAC inventory in large numbers. SAC had used its reconnaissance B-50s for many long photo, ELINT, and COMINT collection missions along the borders and coasts of hostile territory (and occasionally into denied territory) from 1952 on. For these missions they retained the defensive armament of the B-29: four remotely-controlled turrets (upper and lower forward, and upper and lower aft), and a manned tail gun position. The upper forward turret had four .50-caliber machine guns, the other three turrets had two .50-caliber machine guns each, and the tail position had two or three .50 caliber machine guns.
When we published an article about the ATRAN mission last year, we enclosed a photo of RB-50 number 49-307, a 7406th bird, which showed it completely devoid of armament. The historian for the 7406th Association, Al Rasimas, wrote me and noted this. He also said the RB-50 veterans of the 7406th had told him their aircraft were always armed. So I did some research and found out that both pieces of information are correct. The RB-50s did carry their armament on collection missions. Note the adjacent photo of 7406th RB-50 47-136 on the wash rack at Rhein-Main in April 1958, just before it was to depart the 7406th for its next assignment. Noticeable is the upper front turret with its four .50 cal guns.
Note next the photo of the "clean" RB-50 49-307. This shot was taken on a visit to a British base, RAF Bovingdon, on 3 October 1957. This aircraft had been one of the Half Track ATRAN birds, but when that program was cancelled in 1956 and the other ATRAN aircraft left Rhein-Main, #307 was retained as a flight trainer for the other RB-50 crews. It was during this time that the photo below was taken.
The aircraft had been stripped of its armament, as well as its external fuel tanks, for its training mission. Before long it was relegated to ground duties, being reportedly used mainly as a serviceable engine stand. It was also a source of needed spare parts for the operational aircraft. Eventually, in August 1958, it was flown back to the US to join the 1707th Air Transport Wing (MATS) at Palm Beach, Florida. In January 1960 it was deleted from the AF inventory.
Although the operational RB-50s retained their armament and carried gunners as crewmembers, I get the sense from the unit histories that it was very difficult for the gunners to gain and maintain proficiency in their craft. Not a lot of time appears to have been allocated for such training. Furthermore, during 1957 and 1958, the years that the 7406th had its RB-50s, there were no reported instances where the guns had been used, or even threatened to be used, against hostile aircraft.

The hummingbird has a number of adaptions that allow it to fly with breathtaking agility and precision. A new technique using stroboscopic laser sheets allowed scientists to see how air flows over a hummingbird’s wing, which led to some surprising discoveries. Some of the aerodynamic effects used by the hummingbird can be found on all sorts of varying aircraft.
To begin, lets examine the mechanics of a hummingbird’s wing stroke. When hovering, the hummingbird has a flat figure-eight stroke lying in the horizontal plane. Unlike most birds, the hummingbird develops lift on both the downstroke and the upstroke. During the upstroke, the hummingbird is able to twist its wing backwards to attain an angle of attack suitable for generating lift because of its flexible shoulder joints. The camber of the hummingbird’s wing can also change to increase the amount of lift generated on the upstroke.
Using a new technique called digital particle imaging velocimitry, scientists were able to determine that 75 percent of the lift was produced on the downstroke, and the remaining 25 percent on the upstroke. This contradicts the previous speculation that the distribution was 50-50, which is the lift distribution for most insects. The digital particle velocimitry technique uses particles of atomized olive oil that have been dispersed in the air and illuminated by a laser sheet. This allows scientists to accurately make observations about the movement of air around the hummingbird’s wings. One discovery scientists made was that hummingbirds generate lift on the upstroke with the help of leading edge vortices. Leading edge vortices are used by many insects to generate lift, so it was a surprise to discover hummingbirds taking advantage of this phenomenon.
Wing-generated vortices are very important in the development of lift for animals and man-made vehicles alike. To understand leading edge vortices we first must understand the general concept of a vortex. A vortex is a type of fluid flow characterized by rotation about a theoretical axis. However, this axis does not have to be a line; it can be curved or even circular. On all wings, tip vortices form as the higher pressure on the lower surface tries to equalize with the lower pressure on the upper surface of the wing by curling over the wingtip, creating a rotational motion. Wingtip vortices of both fixed and rotating wings decrease the efficiency of the airfoil(s) by lowering lift and increasing drag. Efforts have been made to minimize these vortices by adding winglets or other wingtip devices, or by designing the aircraft to operate in close proximity to the surface in a state pilots call ground effect. In certain conditions, the tip vortices of helicopters can be amplified even to the point that the helicopter can no longer generate lift.
Leading edge vortices, on the other hand, increase lift and do not occur on all wings. As stated before, they are created by insect wings, as well as aircraft with highly swept back delta wing planforms. On insects, leading edge vortices form when the flapping motion of the wings interrupts the laminar flow of the oncoming air in such a way that influences it to rotate. This rotation provides lift to the wing in addition to the lift developed by traditional means. Because of the small wing size necessary to create these vortices as a result of flapping motion, only insects and hummingbirds are able to take advantage of this aerodynamic effect.
Although hummingbirds have adapted an amazing ability, it comes at a cost like everything else. The aerodynamic process of hummingbird hovering is comparatively inefficient and thus requires a relatively large amount of energy, which is why hummingbirds have an extremely high metabolism rate. The slow process of evolution and adaption of all species, including hummingbirds, has shown that nature is an engineer and can solve its own problems. This only adds to the impressive abilities of the hummingbird; nature’s only living hovering avian.

Update for April 28: SpaceX is now targeting Friday (April 28), to launch its sixth Falcon Heavy mission carrying satellites for ViaSat, Astranis and Gravity Space. The mission has been delayed from April 25, 26 and 27 due to bad weather at its Pad 39A launch site at NASA’s Kennedy Space Center in Florida. Liftoff is currently set for 7:29 pm ET (2329 GMT).
SpaceX’s powerful Falcon Heavy rocket will launch for the sixth time ever Friday (April 28), and you can watch the action live.
The Falcon Heavy is scheduled to lift off from NASA’s Kennedy Space Center in Florida at 7:29 p.m. EDT (2329 GMT) on Friday, carrying three satellites toward distant geostationary orbit.
The primary payload on Friday’s mission is ViaSat-3 Americas, a 14,000-pound (6,400 kilograms) broadband satellite that will be operated by California-based company Viasat.
The second satellite flying Friday is Arcturus, a communications craft that will be operated by San Francisco-based Astranis Space Technologies.
“Although it only weighs 300 kg [660 pounds], the mighty communications satellite has the ability to provide data throughput up to 7.5 Gbps for … Alaska and the surrounding region,” EverydayAstronaut.com wrote (opens in new tab) of Arcturus in a description of today’s flight.
The third payload is GS-1, a cubesat that will be operated by Washington-based Gravity Space. GS-1’s primary mission involves providing communications for Internet of Things applications, though it will do some other things in orbit as well.
“The spacecraft is also designed to provide orbital slot reservation services (BIU) around the geosynchronous arc. The spacecraft features three wideband frequency bands,” Gravity Space wrote in a description of the satellite (opens in new tab). “The spacecraft will also carry an imaging system capable of imaging both the Earth and spatial bodies, as well as an experimental rendezvous and docking payload.”
The Falcon Heavy consists of three strapped-together first stages of SpaceX’s workhorse Falcon 9 rocket. The central booster is topped with an upper stage and the payload(s).
Falcon Heavy debuted in February 2018 with a memorable test flight flight that sent SpaceX founder and CEO Elon Musk‘s red Tesla Roadster into orbit around the sun with Starman, a spacesuit-clad mannequin, at the wheel.
The Falcon Heavy’s three first-stage boosters are designed to be reusable. However, none of the boosters will be recovered on today’s mission, presumably because they won’t have enough fuel left over to maneuver themselves safely back to Earth for a vertical touchdown.
For more than five years, the Falcon Heavy was SpaceX’s most powerful rocket. But the company’s gigantic Starship vehicle took that title with its debut liftoff on April 20, a test flight that reached a maximum altitude of 24 miles (39 kilometers) and ended in a commanded explosion high above the Gulf of Mexico for safety’s sake.
Starship’s 33 first-stage Raptor engines generate 16.7 million pounds of thrust at liftoff, according to SpaceX (opens in new tab). That’s more than three times more than the Falcon Heavy produces, and nearly twice as much as the second-place vehicle, NASA’s Space Launch System megarocket.
Friday’s planned launch has been delayed several times by bad weather. An attempt was called off on Thursday (April 27), for example, as weather officials issued tornado warnings (opens in new tab) for Florida’s Space Coast.
Editor’s note: This story has been corrected to state that Starship produces 16.7 million pounds (not tons) of thrust at liftoff.

USAAC/ USAAF/ USAF aircraft designation systems
The US Air Force and its predecessors have used a series of designation systems to identify their aircraft, starting by using the manufacturer's own codes then adopting a system of type numbers and two letter codes in 1919-20. This was replaced by the more familiar basic mission system in 1924, with single letters for most aircraft types. This remained in use (with variants) until 1962, when it became the basis of the current Tri-service aircraft designation system. | aerospace |

All three companies are developing new launch vehicles that will be used to launch satellites into space in the future. Anna Christmann, Federal Government Coordinator of German Aerospace Policy, is accompanying Minister Habeck on the microlauncher tour.
"Just a few years ago, no one would have believed that you could start a rocket company in Germany and today we have three of them. High-tech startups from Germany provide important impetus for space travel in Europe", said Economic Affairs Minister Habeck ahead of the trip. "Germany and Europe need their own access to space – this is also a question of economic security. At present, Europe has no launch facilities of its own for satellites. This shows that something has to change in the European launch sector. We need more competition and private sector involvement. Private providers drive innovation, increase our resilience and ensure that government agencies can buy launch services as anchor customers in the future – and more cheaply than if they continue to do everything themselves."
The Federal Ministry for Economic Affairs and Climate Action is funding all three companies visited with a total of around 25 million euros as part of its microlauncher competition. Microlaunchers are small modern rockets that are designed to initially carry payloads in the range of 150 to about 1,000 kilogrammes into space. The aim of the funding is to promote the commercialisation of the sector, i.e. to support private launch service providers in developing their launchers and setting up their companies.
The first stop on the journey today is Neunstadt am Kocher in Baden-Württemberg, where HyImpulse Technologies GmbH has its headquarters. Here, near the largest German rocket test site in neighbouring Lampoldshausen, a team of 55 employees is currently working on the sounding rocket "SR75". This is to be followed by the "SL1" orbital rocket, which will carry payloads of up to 400 kilogrammes into space. HyImpluse is pursuing a particularly innovative approach with the main engine of its rocket: it runs on a solid fuel, i.e. paraffin (wax), which is combined with liquid oxygen.
The tour then continues to Rocket Factory Augsburg AG in Swabia (Bavaria), a spin-off of the German aerospace company OHB and its subsidiary MT Aerospace. Some 220 employees are working on the "RFA One" launcher at sites in Augsburg, Portugal and Sweden. It will be able to launch up to 1.3 tonnes of payload into space. Here, too, a special engine technology is being used: a so-called "staged combustion engine", unique within Europe, which is considered particularly fuel-efficient.
To conclude the trip, Minister Habeck will visit Isar Aerospace Technologies GmbH south of Munich in Ottobrunn on Friday. A total of 300 employees are working here on the "Spectrum" rocket. This rocket will be able to launch satellites weighing up to one tonne. So far, Isar Aerospace has been able to raise about 330 million euros in private funding. This makes the company the best financed new space company in Europe.
Anna Christmann: "In the new age of space travel, it is crucial that the state acts as an anchor customer for new technologies and thus attracts private capital. In the case of the three microlauncher companies, this has been excellently done and will also be a focus of our new space strategy. We are very excited to see the first German microlauncher fly into space from a European launch site. What has also been fundamental to the success of the microlauncher start-ups so far is the promotion of young talent by the German Space Agency at the German Aerospace Center and by the German universities. The student groups from the latter have mainly founded these companies." | aerospace |

Located on 553 hectares, 7 kilometres North of Paris, Paris-Le Bourget is the leading business airport in Europe. With its three runways and parking areas, it can accommodate all types of aircraft.
Paris-Le Bourget is also an important centre of the aviation industry: some thirty buildings accommodate more than 100 maintenance firms, aircraft equipment and facilities, and airport services. The ongoing operations of the airport generates more than 3,500 direct jobs. The number of aircraft and helicopter movements totalled approximately 54,971 in 2013.
Awareness of the Paris-Le Bourget airport is enhanced by its proximity to the Paris-Le Bourget Exhibition Park, which hosts every two years, in particular, the International Aviation and Space Salon ( IASS). In 2013, 315,000 visitors gathered there. It has hosted 2,200 exhibitors from 44 countries.
The Paris-Le Bourget airport is a major focus of the Group's property business and a large share of property income of the Paris-Le Bourget is closely linked to business aviation.
To reduce noise pollution for local residents, takeoffs of jet aircraft, the use of reverse thrust devices and the use of runway 2 by planes of more than 5.7 tons are prohibited between 22:15 and 6:00.
The market for business aviation
Business aviation is used both as a professional tool by companies as well as by individuals under three complementary forms:
- the business aviation market, where transport companies upon demand lease aircraft "taxis" with their crew for the duration of a flight, and for which the cost of travelling depends on the type plane and the number of flight hours
- business aviation timeshares, in which a company acquires a share of a plane corresponding to a certain annual volume of flight hours
- aviation business called "corporate", in which a company has its own fleet and employs its own crews for its unique needs
Strategy of the airport
The strategy of the airport is built around an offer of high-end services to business travellers to help accommodate an important growth of business traffic and stimulate local economic activity. The market for business aviation offers significant growth opportunities with the emergence of new products and services, the economic development of Eastern European countries (which are not well served by commercial airlines) and an increase in the performance of business aircraft. | aerospace |

More than half a dozen Cannon Air Force Base pilots donned flight gear early Sunday morning in preparation for their final deployment from the 27th Fighter Wing.
The pilots are members of the 522nd Fighter Squadron, which is also known as the Fireballs.
The pilots are part of a large group of airmen who will spend approximately four months in a an undisclosed Pacific theater location, according to Cannon Public Affairs spokesperson Lt. George Tobias. Tobias declined to divulge the exact number of airmen or the specific location of the deployment for safety reasons.
“Obviously, we can not give that information at this time because safety (for our airmen) is paramount,” Tobias said.
Tobias said Sunday’s deployment marks the last major deployment before the 27th Fighter Wing is inactivated Sept. 30. The Air Force Special Operations Command will assume command of the base Oct. 1.
Upon its return, the 522nd Fighter Squadron will be inactivated, Tobias said. The Fireballs will be the second squadron to be inactivated. The 523rd Fighter Squadron, or Crusaders, was inactivated May 9.
522nd Fighter Squadron Commander Lt. Col. Tod Fingal described the final deployment as bittersweet.
“The 27th Fighter Wing has a legacy at Cannon,” Fingal said, “but the transition to AFSOC is great for west Texas, New Mexico and the Air Force.
Fingal, who has been based at Cannon for four years, said Cannon airmen would begin training with foreign allies and other military services during the deployment.
“We (Cannon airmen) have been training for this deployment for a year,” Fingal said, “including two exercises at Nellis Air Force Base in Las Vegas, Nev.”

The Expedition 67 crew is preparing for the departure of the first private astronaut mission and the second spacewalk on the International Space Station. On Friday, there was still time in the orbital laboratory of biomedical sciences to learn more about how the human body adapts to micro-gravity.
Tom Marshburn, NASA’s station commander, spent some time on Friday helping four departing Axiom Mission 1 (Ax-1) crew members. The first private space quartet is set to end a two-week stay at the station this weekend. AX-1 Commander Michael Lopez-Alegria will board the SpaceX Dragon Endeavor along with pilot Larry Connor and mission specialists Mark Pathi and Eaton Steibe and close the hatch at 4:30 p.m. Saturday EDT. The four Ax-1 astronauts will then undock at 6:35 p.m. From the Harmony module’s space-facing port for a Sunday splashdown off the coast of Florida.
The next mission event planned for the station is the fifth spacewalk of the year for further maintenance and upgrades to the station. Roscosmos astronauts Oleg Artemyev and Denis Matveev will once again partner on April 28 to continue activating the European Robotic Arm (ERA) attached to the Nauka Multipurpose Laboratory module.
The two joined fellow astronaut Sergei Korsakov on Friday morning and reviewed plans for the upcoming spacewalk. That trip will see ERA’s first move to set up a manipulator for future robotic activities in the Russian section of the station. The trio then spent the rest of Friday in various inspection and maintenance work.
NASA flight engineers Kayla Baron and ESA (European Space Agency) flight engineer Matthias Moore processed the morning blood and urine samples for later analysis. NASA flight engineer Raja Chari worked on life support gear and then joined Marshburn for pre-departure activities aboard the Dragon Endurance Crew. | aerospace |

Helicopter sightseeing offers a once-in-a-lifetime experience. Aerial perspectives are simply out of this world, and the views from a helicopter are spectacular. You’ll be able to see the sights from above and get visual stimulation that you wouldn’t experience otherwise.
Choosing a helicopter
When choosing a helicopter for your helicopter flight tourism, there are several factors to consider. First, make sure that the pilot is a highly-skilled professional. Helicopter pilots undergo rigorous flight training and must have thousands of hours of experience in the field. Make sure that the pilot is also licensed and insured to fly helicopters. You should also ask the pilot about safety and flight hours, and you should also check the NTSB website for any recent incidents of helicopter accidents.
Another factor to consider when choosing a helicopter is the number of passengers. Helicopters carry fewer passengers than planes, so you can enjoy a private flight if you prefer. Large groups can also enjoy helicopter tours, but smaller groups may be more comfortable with a smaller helicopter. The novelty factor can help tip the scales in favor of a helicopter tour. While helicopters are still a common mode of transport, you may be pleasantly surprised by the low-flying aircraft used in helicopter flights.
The cost of the tour should be considered carefully. Some tours are cheap, while others are expensive. A good price-to-value ratio means you’ll save a lot of money. In addition to safety, you’ll enjoy your helicopter tour more if it’s accompanied by a professional pilot. A well-informed pilot will know how to balance the helicopter’s weight so you get the most out of it.
Choosing a tour company
Before you choose a helicopter flight tour company, there are a few factors you should consider. Helicopter tours are expensive, so you should make sure that the tour itinerary is worth the price. If you plan to see several destinations, you should choose a company that covers all of them and offers guided tours of each one. The more attractions the tour includes, the more value you will get. It is also important to make sure that the pilots of the helicopter tour company have the necessary certifications to operate it safely.
One of the most important aspects of a helicopter flight tour is the pilot. If the pilot doesn’t have enough experience, you may find yourself stuck in the middle of the plane with a poor view. To avoid this, request to sit in a window seat or in the front row. Many companies allow you to choose between front and center seating. Make sure that you check the company’s website for part 135 certification and call the FAA for more information.
If the company asks for identification, you can rest assured that it is legitimate. Moreover, they have clear signs of their schedules and routes. During the flight, you can also take advantage of the oversized windows that give a different perspective to the famous sites. Lastly, you can check the prices of helicopter flight tours in the United Kingdom. The cost depends on the destination, the duration, and the extra activities you opt for.
Choosing a route
When choosing a helicopter tour, there are several factors to consider. The safety record of a tour is extremely important. Look for tours that are certified by the FAA Part 135 air carrier, which meets higher safety standards than general aviation. You should also inquire about the safe flying hours of the tour company, and check out the NTSB aviation accident database for further information. Then, choose the destination you’d like to visit, and book your tour.
A helicopter tour will vary in duration. Depending on the itinerary, flights will last from 15 minutes to an entire day. Your choice of flight time depends on your personal preferences, such as the glare of the early morning or the fading light of the late afternoon. You’ll also have a choice of prices, as some helicopter tour providers will offer an optional flight to a restaurant in case you’d like to eat dinner afterward. | aerospace |

The American Institute of Aeronautics and Astronautics (AIAA) Club is the only club at Stony Brook University with a focus on aerospace engineering. The aerospace field is large and thriving, growing in interest and popularity, which is why this club was created. Despite the fact that Stony Brook University does not currently offer a major in aerospace engineering, our first president, Matthew Lee, sent out an interest form at the beginning of the Fall 2016 semester and got a great amount of positive feedback. Matthew started working in the summer of 2016 to start this club, and with the help of the rest of our founding members, we were able to successfully create Stony Brook University's AIAA Chapter.
The purpose of this club is to unify students interested in aerospace engineering. Since the aerospace industry doesn't inhabit too much of Long Island, we're hoping that, by getting speakers, working on projects, holding/going to events, and encouraging our members to get their foot in the door of the aerospace field, we will be able to give everyone some experience and insight into the aerospace field and motivate everyone to continue down the path of aerospace engineering.

They are among just six university teams from across Canada selected to conduct a study in a microgravity environment aboard the National Research Council Canada’s (NRC) Falcon 20 jet – the same plane used to train the Canadian Space Agency’s astronauts.
As part of the Canadian Reduced Gravity Experiment Design Challenge (CAN-RGX), the team – called TelOmG – has spent the past year designing and building a unique experiment to examine the impact of space flight on astronauts’ genes.
During the flight, the students will investigate the effects of changes in gravity on the genetic regulation of human telomeres. Telomeres are protective caps at the ends of our chromosomes that are linked to genomic stability. Shortening of telomeres is associated with aging, while lengthening can be associated with cancer.
The idea for the experiment came to team lead Erin Richardson, a fourth-year student in engineering science in the Faculty of Applied Science & Engineering, while reading NASA’s landmark Twins Study, an investigation of spaceflight’s effects on the human body. The study focused on American astronaut Scott Kelly, who spent nearly a year in space, and his twin brother Mark who remained earthbound, and found Scott’s telomeres unexpectedly grew longer during his space flight. They returned to normal shortly after his return to Earth. In contrast, his twin’s telomeres remained stable during the same period.
“Our experiment investigates whether this increase in telomere length was due to reduced gravity or some other factor, such as increased radiation or stress during the space flight,” says Richardson.
Flying parabolic manoeuvres on the NRC’s Falcon 20 will allow the team to isolate microgravity from the other factors present on the International Space Station. However, while Kelly spent months in space, the experiment will only undergo five, 20-second periods of microgravity.
The students had to devise a way to test whether telomeres are affected by microgravity in under 20 seconds. “Telomere length won’t change that fast,” says Richardson. “The key was to focus on the transcription of the genes that control them. Previous studies found transcriptomes changed significantly within 20 seconds of altered gravity.”
Richardson recruited other students from engineering science's aerospace and biomedical systems majors as well as from the life sciences. In addition to Piro, the team includes: MacKenzie Campbell, a graduate of engineering science and master's student in chemical engineering; Dunja Matic and Taylor Peters, both in their fourth year of engineering science; Emma Belhadfa and Luca Castelletto in year three of engineering science; year three life science student, Miranda Badovinac; and Grade 12 students Samantha Aberdein, Krish Joshi, and Nicole Richardson.
The aerospace engineering team members focused on designing and building the physical apparatus, while biomedical systems and life science students designed and tested the experiment’s scientific methods.
“One of the beautiful things that happens when you bring together people with so many different backgrounds, is the ingenuity in the questions they ask each other,” says Rodrigo Fernandez-Gonzalez, an associate professor at the Institute of Biomedical Engineering and chair of engineering science's biomedical systems major. “Those questions often challenge dogmas and assumptions and can ultimately lead to amazing discoveries.”
To test their hypothesis that microgravity contributes to changes in gene transcription related to telomeres, the students will “freeze cells in time” by preserving their nucleic acids before and after each short period of microgravity. They will analyze the nucleic acids after the flight for changes in the expression levels of genes that regulate telomeres.
The experiment’s apparatus consists of a syringe filled with a stabilization solution and connected to a series of chambers containing live cells. The electronic control system will inject the solution into the correct chamber when manually triggered by the students on board the flight just before and after each period of microgravity. Some samples are frozen before any periods of hypergravity or microgravity to control for environmental conditions on board the jet.
The entire experiment had to fit into a 50-centimetre cube and weigh no more than 45 kilograms, among other constraints. “Little things that you wouldn’t normally consider are much more challenging in microgravity,” says Castello, the team’s mechanical lead.
“For example, we had to ensure everything is absolutely leak-proof and secured so that there’s no chance of small components or liquid floating around the plane’s cabin. Since we are dealing with cells, we had to create a sterile system while also minimizing bubbles that could interfere with our fluid pathways.”
Team TelOmG presented their proposal at the Johnson Space Centre Astronomical Society in June and has been invited to share their findings at the International Astronautical Congress in Dubai in October.
Conducting research during a pandemic presented additional challenges. Access to wet labs and lab safety training was restricted. “We’ve been blown away by the support we received from professors, researchers and private companies during this time,” Belhadfa says. “They helped us to get what we needed when public health restrictions created obstacles.”
Team members also had to work on components in isolation for many months. “Normally when we work in a team and something goes wrong during equipment testing, we have a good laugh together,” Castelletto says. “It’s a lot less funny when you’re all alone in your house.”
Planning and testing a complex experiment from start to finish has been an eye-opening journey for the team. “From our experiences in design courses like Praxis, we knew to expect things not to go as planned,” Campbell says. “We really learned to take a wide view of the project and lean on our project management skills.”

The agreement paves the way for new transatlantic collaboration in the aerospace and aeronautics sectors and is excellent news for Walloon exports.
The partnership was concluded during the Walloon economic and technology mission to Quebec and Ontario.
The collaboration is based around three fields of research: composite materials, whose use can reduce the weight of aircraft; digital simulation for calculating materials' fatigue resistance; and the 3D printing of metal aircraft parts.
The agreement strengthens the economic links between Wallonia and Quebec and also takes the relationship between the two regions to almost historic levels. Sonaca, one of the largest Walloon aeronautics businesses, is the Belgian benchmark when it comes to setting up in Canada. The Charleroi company has been operating in Canada for almost 25 years; it now employs 350 people in Montreal and its sales figures are constantly growing. Its activities include the manufacture of the wing structures for the Airbus A330 and several types of Bombardier aircraft.
Aeronautics is an important sector in Wallonia, providing 5,400 direct industrial jobs. Montreal is the 3rd largest global aeronautics centre, providing 43,500 aeronautics jobs in the province of Quebec.

By Wendy January 25, 2001 at 03:04:46
My grandfather flew Gooney Birds in the Canal Zone. He was in the 20th transportation/ 6th Army Air Corp, sometimes referred to as the Carribean Air Force /Antilles AF / Army Air Force. I have evidence he was at Albrook Field at some point, though I believe he may have ended up at Harold (?) Field. I also know he flew between there and Trinidad. When he left the Canal Zone he became an instructor at the Reno Sky Ranch where he taught glider pilots.
Would love to learn more about the:

NASA has launched the “Hot Ticket” program which will allow the public to get their names on the Parker Solar Probe in a tiny memory card.
It is a symbol of appreciation from NASA for its space fans and it is actually really cool. To get your name registered, you have to enter your name and email on NASA’s sign up page. You will then receive a confirmation email on which you’ll find a link, click that link and you will be confirmed to have your name registered. You can download the digital ticket from there.
The Parker Solar Probe which will be sent on the journey will face the harshest conditions by a spacecraft till date. A four inches heat shield will protect it from the Sun’s extreme heat. It will orbit at a distance of 4 million miles and will face a temperature of 2500 degree Fahrenheit, but according to NASA the equipment inside the probe will remain at room temperature.
The information gathered from the probe will be sent back to earth to properly study how the Sun works. The probe, which is about the size of a small car, will make multiple loops around the Sun during its mission, inching ever closer while gathering data about the star’s magnetic field and atmosphere.

It did a tethered flight, and will soon be doing an untethered one.
“This fully rigid airship, dubbed the Aeroscraft, differs fundamentally from, say, the Goodyear blimp. Blimps, by definition, have no internal structure and maintain their shapes only through the pressure of the gas they contain; when the gas escapes, they deflate like the gigantic balloons they are. Rigid airships, like zeppelins before them, maintain their shape regardless of gas pressure thanks to an internal skeleton structure—the Hindenburg utilized highly flammable balsa wood, but the Aeroscraft’s is made of aluminum and carbon fiber—and maintains its buoyancy with a series of gas-filled bladders. And unlike hybrid airships, the Aeroscraft doesn’t require forward momentum to generate lift via a set of wings. It’s all hydrogen power.” | aerospace |

The US Government will receive a penalty of $12 million from Boeing, which has also agreed to modify its commercial aircraft production procedures. The penalty is in lieu of settlements of complaints regarding Boeing’s failure to meet safety and quality standards. The second-highest enforcement penalty has been reached by the Federal Aviation Administration (FAA).
According to the FAA, Boeing will have to pay up to $24 million in additional penalties in case it fails to keep up with the agreement over a period of next five years. Under the agreement, Boeing is required to enhance its management oversight, accountability and internal audits. Furthermore, the company is supposed to organize additional training programs and gradually follow more stringent quality and timeliness performance parameters.
The agreement has been formed to settle two FAA enforcement cases and 11 other complaints registered with Boeing during last few years. One of the two FAA cases involve the missing of deadline by Boeing to give directions to airlines for fitting 747 and 757 jets in 2012, to avoid the explosion of fuel tanks. It became mandatory to install these devices following the explosion of a TWA-operated 747 jumbo jet in 1996. In 2013, Boeing installed inappropriate fasteners on 777s and subsequently failed to resolve the issue during the next two years.
Boeing repeatedly failed to achieve the deadlines of its own action plans, according to the FAA. Boeing’s infringements include postponing installment of crucial safety equipment and unable to supervise its own production processes. However, now Boeing has reported that it has already completed several enhancements, as required under the accord, while others are under process.

Trump directed U.S. Secretary of Transportation Elaine L. Chao today to launch an initiative to safely test and validate advanced operations for drones in partnership with state and local governments in select jurisdictions.
To date, Over one million UAS owners have registered with the Federal Aviation Administration (FAA)
The program will help tackle the most significant challenges in integrating drones into the national airspace while reducing risks to public safety and security. The program is designed to provide regulatory certainty and stability to local governments and communities, UAS owners and operators who are accepted into the program. In less than a decade, the potential economic benefit of integrated unmanned aerial systems into the nation’s airspace is estimated to equal up to $82 billion and create up to 100,000 jobs.*
The program will help the USDOT and FAA develop a regulatory framework that will allow more complex low-altitude operations; identify ways to balance local and national interests; improve communications with local, state and tribal jurisdictions; address security and privacy risks; and accelerate the approval of operations that currently require special authorizations.
“This program supports the President’s commitment to foster technological innovation that will be a catalyst for ideas that have the potential to change our day-to-day lives,” said Secretary Chao. “Drones are proving to be especially valuable in emergency situations, including assessing damage from natural disasters such as the recent hurricanes and the wildfires in California.”
The pilot program will evaluate a variety of operational concepts, including night operations, flights over people, flights beyond the pilot’s line of sight, package delivery, detect-and-avoid technologies, counter-UAS security operations, and the reliability and security of data links between pilot and aircraft. Industries that could see immediate opportunities from the program include commerce, photography, emergency management, precision agriculture, and infrastructure inspections and monitoring.
Some highlights of the program:
- the program will accelerate testing of currently restricted UAS operations
- open the skies for inspections of critical infrastructure, support for emergency management operations
allow testing of new UAS traffic management systems
help in the development of a future national aviation regulatory framework
“Stakeholders will have the opportunity through this program to demonstrate how their innovative technological and operational solutions can address complex unmanned aircraft integration challenges,” said FAA Administrator Michael Huerta. “At the same time, the program recognizes the importance of community participation in meaningful discussions about balancing local and national interests related to integrating unmanned aircraft.”
Prospective local government participants should partner with the private sector to develop pilot proposals.

Now, luggage brand Arlo Skye is joining the frenzy and launching a carry-on collection inspired by the exploration of outer space.
Now on sale, the Space Collection features three designs of the brand's polycarbonate silver carry-on: "Team Human," "Moon Shot," and "Occupy Mars." Each of the three suitcases features a custom-designed insignia and an ode-slash-factoid about outer space—all of which has been laser-etched onto the surface using ultra-fast pulses of light. The small details of the collection are on theme for Arlo Skye, which was founded in 2016 by former Louis Vuitton and Tumi execs and billed as a luggage brand for the design-obsessed traveler. "Every detail is purposeful, yet restrained. It leaves room for the user’s self-expression," said Chief Design Officer Denielle Wolfe when the brand launched. That pretty much sums up the deep-space inspired suitcases—sleek and simple but definitely making a statement for the traveler.
Like the brand's signature luggage, the Space Collection carry-on is zipper-less and engineered in a hard polycarbonate shell with an aluminum frame. It has a powerful portable charger that can be removed with the push of a button, plus two TSA-approved combination locks. It's 22 inches tall and 8.5 pounds—the perfect size for three-day summer weekend trips. In a press release, Arlo Skye wrote that the bag is sized "potentially for interplanetary voyages." Judging by our packing habits, we might need the larger suitcase for a trip to outer space, but until then, we'll settle on the carry-on.

Rocket Lab will arrive on Wall Street in a deal with a blank-check company that pegs the 15-year old satellite launcher’s value at $4.1 billion.
Rocket Lab first announced its plans in March to go public by merging with a blank check company Vector Acquisition Corp., backed by San Francisco-based investment firm Vector Capital. Shareholders on Friday approved the merger. The company will trade on the NASDAQ beginning Aug. 25 under the ticker symbols RKLBW and RKLB.
It couldn’t come at a better time, with the market for satellite launches growing and the company mired in debt. Rocket Lab, which has raised $400 million in capital, lost $55 million alone last year, according to filings. That net loss is an increase from 2019, which saw the company lose about $30.4 million. The company declined to comment for this article.
In an investor presentation filed Aug. 18, Rocket Lab revealed just how tough it has been to sustain its reusable rocket, called Electron, and take on SpaceX CEO Elon Musk.
“The Company has suffered recurring losses from operations that raise substantial doubt about its ability to continue as a going concern,” auditors noted.
The deal is projected to give Rocket Lab some much-needed funds, nearly $750 million in cash. Vector will contribute the majority of that money but existing Rocket Lab investors BlackRock and Neuberger Berman, which are part of the special purpose acquisition company or SPAC, will also participate.
“This is just like a supercharger – we have all the things we need now to go and do the things that we’ve dreamed of,” Rocket Lab CEO Peter Beck told CNBC when the company announced the plan.
Rocket Lab’s Launch Complex 1 in New Zealand.
Over the past four years, the company has launched 21 missions mostly with small payloads, but it wants to be able to catch up to SpaceX, which can launch up to 60 of its own satellites on the huge Falcon 9 rocket.
Rocket Lab plans to commit roughly $200 million to develop a second recyclable craft called Neutron by 2024. Neutron is medium-sized and not as roomy or costly as the Falcon 9 rocket, but it’ll help Rocket Lab launch mass satellite launches and pursue human spaceflight, two of Musk’s pet projects.
The merger could be a key stepping stone in Rocket Lab’s development and provide it with some much-needed cash and give the company a larger foothold in the private space race and challenge SpaceX for dominance.
In its prospectus filed last month, Rocket Lab said it wants to be the go-to company for “cost-effective launch for mega-constellations and human spaceflight.”
Musk is using SpaceX to launch thousands of satellites into space in an attempt to create his Starlink constellation of satellites with the goal of providing global high-speed internet. Musk is also vocal about his desire to colonize Mars and increase space tourism, but he’s not alone there — Blue Origin founder and former Amazon chief Jeff Bezos day-tripped to space last month, shortly after Virgin Galactic founder Richard Branson.
According to Rocket Lab, it’s one of the only companies besides SpaceX to provide “regular and reliable” access to orbit. Rocket Lab has contracts with NASA to send twin satellites to observe Mars and is one of several contractors working on NASA’s Artemis Program, which plans to land the first woman to the moon to establish a base.
After a failed launch in May, Rocket Lab successfully sent a Space Force research satellite into orbit — its fourth launch this year. It also inked a deal Aug. 18 to send four satellites into orbit for Scottish manufacturer Alba Orbital in the fourth quarter.
Rocket Lab operates facilities in Virginia, New Zealand and Toronto in addition to its Long Beach headquarters. The company will look to break ground on a new factory to create the Neutron in fourth quarter of this year and expects it will be operational by fourth quarter 2022. Like competitor Relativity Space, Rocket Lab uses 3D printing to make rocket parts, including engines.

Plagued by an undiagnosed problem that stranded it in Earth orbit, Russia's Phobos-Grunt Mars mission remained quiet Tuesday after renewed attempts to coax the craft back into contact with ground controllers.
European Space Agency officials transmitted signals to raise Phobos-Grunt's orbit Tuesday in hopes it would allow greater communications opportunities at a higher altitude, according to the agency's Twitter page.
The ploy didn't work, and the probe remains in a low-altitude orbit less than 200 miles above Earth.

The UK Airprox Board (UKAB), which will publish its findings on
Friday, is expected to record an incident risk rating of A – the highest
of five categories – defined as a “serious risk of collision”.
The report, seen by the Sunday Times,
said the pilot of an Airbus A320 spotted the drone, which failed to
show up on air traffic control systems, at 2.16pm on 22 July while
flying at an altitude of 700ft.
The pilot reported the incident to the UKAB, which launched an inquiry, but the owner of the drone has never been identified. | aerospace |

The closure of its operation at 7º East coincided with the entry into service of the new Eutelsat 7C, which in recent weeks had taken over the telecommunications services that the former had been providing.
Eutelsat 7A was initially born as Eutelsat W3A was launched into space on March 16, 2004, equipped with 58 transponders.
Despite having officially ended its useful life, it was estimated at 15 years, now Eutelsats 7A is heading towards another position where it will be used by the satellite company until it runs out of fuel left in its tanks.
Near the new position of the Eutelsat 7A satellite, Intelsat 33e, from the American operator Intelsat, is operational at 60 ° East.

SpaceX has constructed and delivered its two hundredth Falcon second stage, highlighting the rocket’s typically underappreciated report of accomplishment on the bottom and in flight.
About 13 years in the past, in late 2009 or early 2010, SpaceX launched the primary flyable prototype of the primary iteration of the second stage of the Falcon 9. In June 2010, the Falcon 9 launched on its first take a look at flight and, with this second stage, efficiently launched a prototype spacecraft mockup into orbit. of the Dragon ship. After the shock inaugural success of the Falcon 9, SpaceX’s Falcon 9 and Falcon Heavy rockets have been launched 187 extra instances, for a complete of 188 launches and 189 assembled rockets. Every of those launches required a brand new second stage, and all however one (the Crew Dragon In-Flight Abort take a look at) required a brand new Merlin Vacuum engine.
Whereas SpaceX is greatest identified for its profitable implementation of reusable, rapid-use Falcon boosters, the corporate’s general success can also be inextricably linked to Falcon second phases, that are expendable and can all the time be expendable after every launch. For each spectacular touchdown or report reuse of a Falcon launch car, the second stage of the Falcon both unceremoniously burns up within the Earth’s environment or leads to orbit. Because of this, despite the fact that SpaceX’s multi-use functionality allowed it to launch greater than ever earlier than with a fleet of simply 10-20 Falcon launch autos, the corporate needed to ramp up manufacturing of the Falcon’s extraordinary second phases.
SpaceX simply accomplished its 188th Falcon 9/Heavy launch, so the two hundredth flyable second stage and Merlin Vacuum (MVac) engine is probably going scheduled for January 2023. Over the previous three hundred and sixty five days, SpaceX’s Falcon rockets have accomplished 59 profitable orbital launches. Every launch required a brand new second stage, so on common SpaceX constantly constructed, shipped, and examined a brand new Falcon second stage each 6.2 days for extra than a yr.
Due to SpaceX’s report launch frequency in 2022, which has resulted in additional Falcon 9 launches per calendar yr than every other rocket in historical past, the Falcon second stage is more likely to be the most-produced orbital rocket stage in many years. Barring any surprises, SpaceX is on monitor to satisfy CEO Elon Musk’s objective of 60 Falcon launches by 2022. However SpaceX is not performed but, with CEO Elon Musk saying the corporate plans “as much as 100 launches” in 2023. After almost doubling the quantity between early and late 2021, that may require an extra ~67% improve in Falcon second stage manufacturing in comparison with final yr.
Throughout its 12.5-year profession, the Falcon 9 suffered three failures. In October 2012, throughout the third launch, one of many 9 Falcon 9 Merlin 1C booster engines failed in flight. The principle mission – the Dragon cargo mission to the Worldwide House Station – was saved by the second stage, which autonomously compensated for the misplaced efficiency, however the secondary payload (the primary prototype OG2 Orbcomm satellite tv for pc) was misplaced because of this. In June 2015, a defective strut contained in the Falcon 9’s second stage precipitated a helium stress vessel to flee and rupture, destroying the rocket in flight. And in September 2016, throughout a pre-launch static hearth take a look at, an identical stress vessel within the Falcon 9’s upgraded second stage ignited spontaneously, inflicting an explosion that destroyed the rocket whereas it was nonetheless on the bottom.
Because of this, whereas issues with the Falcon’s second phases technically precipitated the Falcon 9’s solely catastrophic failures, it stays true that the free-flying Falcon’s second stage has by no means failed in flight. The identical is true for the second stage Merlin Vacuum engine: in a whole bunch of burns and over 70,000 seconds of operation, the MVac has by no means as soon as didn’t fly.
Following the profitable launch of the Eutelsat Hotbird 13G Falcon 9 communications satellite tv for pc on November 3, 2022, SpaceX’s Falcon household of rockets has accomplished 160 launches with out failure, presumably making it essentially the most dependable household of rockets in historical past. To attain this success with the partially reusable Falcon 9 and Falcon Heavy rockets, SpaceX needed to grasp reusable rockets and single-use orbital rockets to the purpose that solely a handful of different firms or house companies in historical past can declare to have matched or surpassed them, and that nobody has achieved on the similar time.

In your lifetime you will only be able to remember where you were for certain monumental events in history, and this is one of them for me. I was in a barracks TV room in Seattle Washington in the Marines, when we watched Niel Armstrong set foot on the moon. America has lost a great icon. Only a handful of humans have set foot on another place other than this earth, and we have lost another one today.
CINCINNATI (AP) — Neil Armstrong was a quiet self-described nerdy engineer who became a global hero when as a steely-nerved pilot he made "one giant leap for mankind" with a small step on to the moon. The modest man who had people on Earth entranced and awed from almost a quarter million miles away has died. He was 82.
Armstrong died following complications resulting from cardiovascular procedures, a statement Saturday from his family said. It didn't say where he died.
Armstrong commanded the Apollo 11 spacecraft that landed on the moon July 20, 1969, capping the most daring of the 20th century's scientific expeditions. His first words after setting foot on the surface are etched in history books and the memories of those who heard them in a live broadcast.
"That's one small step for (a) man, one giant leap for mankind," Armstrong said.
In those first few moments on the moon, during the climax of heated space race with the then-Soviet Union, Armstrong stopped in what he called "a tender moment" and left a patch commemorate NASA astronauts and Soviet cosmonauts who had died in action.
"It was special and memorable but it was only instantaneous because there was work to do," Armstrong told an Australian television interviewer this year.
Armstrong and Buzz Aldrin spent nearly three hours walking on the lunar surface, collecting samples, conducting experiments and taking photographs.
"The sights were simply magnificent, beyond any visual experience that I had ever been exposed to," Armstrong once said.
The moonwalk marked America's victory in the Cold War space race that began Oct. 4, 1957, with the launch of the Soviet Union's Sputnik 1, a 184-pound satellite that sent shock waves around the world.
Although he had been a Navy fighter pilot, a test pilot for NASA's forerunner and an astronaut, Armstrong never allowed himself to be caught up in the celebrity and glamor of the space program.
"I am, and ever will be, a white socks, pocket protector, nerdy engineer," he said in February 2000 in one of his rare public appearances. "And I take a substantial amount of pride in the accomplishments of my profession."
A man who kept away from cameras, Armstrong went public in 2010 with his concerns about President Barack Obama's space policy that shifted attention away from a return to the moon and emphasized private companies developing spaceships. He testified before Congress and in an email to The Associated Press, Armstrong said he had "substantial reservations," and along with more than two dozen Apollo-era veterans, he signed a letter calling the plan a "misguided proposal that forces NASA out of human space operations for the foreseeable future."
Armstrong's modesty and self-effacing manner never faded.
When he appeared in Dayton in 2003 to help celebrate the 100th anniversary of powered flight, he bounded onto a stage before 10,000 people packed into a baseball stadium. But he spoke for only a few seconds, did not mention the moon, and quickly ducked out of the spotlight.
He later joined former astronaut and Sen. John Glenn to lay wreaths on the graves of Wilbur and Orville Wright. Glenn introduced Armstrong and noted it was 34 years to the day that Armstrong had walked on the moon.
"Thank you, John. Thirty-four years?" Armstrong quipped, as if he hadn't given it a thought.
At another joint appearance, the two embraced and Glenn commented: "To this day, he's the one person on Earth, I'm truly, truly envious of."
Armstrong's moonwalk capped a series of accomplishments that included piloting the X-15 rocket plane and making the first space docking during the Gemini 8 mission, which included a successful emergency splashdown.
August 27, 2012
When I think about a true American hero, Neil Armstrong is the picture that comes to mind. The things he survived and then went to the moon, knowing they may never make it or even come back, that's what they mean by brass balls.
The modern definition of ‘racist’ is someone who’s winning an argument with a liberal. | aerospace |

All 194 individuals on board survived the flight, which landed safely however its door remained open at Daegu Worldwide Airport on Friday.
Native media reported that a few of the passengers fainted whereas others suffered from respiratory issues and have been taken to hospital.
Yonhap information company reported that the person, in his 30s, stated he felt suffocated and needed to get off rapidly.
Police stated the person claimed throughout his interrogation that he was burdened after dropping his job, in line with the report.
Flight OZ8124, an Airbus A321-200, took off from Jeju Island on Friday round 11:45 native time (03:45 GMT).
When it was touchdown about an hour later, a passenger opened the emergency door whereas the aircraft was nonetheless 250 meters off the bottom.
A passenger video shared on social media reveals a gaping gap within the left facet of the aircraft and winds pounding the rows of seated passengers.
Eyewitnesses instructed native media that the flight attendants have been unable to cease him as a result of the aircraft was about to land.
They stated the person additionally tried to leap out of the aircraft after opening the door.
Passengers described panic on board.
“It was chaos as individuals close to the door appeared to faint one after the other, and the flight attendants have been calling out to the medical doctors on board by means of radio broadcasts,” a 44-year-old passenger instructed Yonhap Information Company.
“I believed the aircraft was going to blow up. I believed I used to be going to die like this,” he added.
A number of school-age kids have been additionally on board, on their approach to a sporting occasion that weekend.
“The youngsters have been shaking, crying and afraid,” the mom of one of many college students instructed Yonhap. | aerospace |

It became obvious when comparing ideas there are too many different opinions about aircraft flight control.
When contemplating the physics of flight it seems there could be only one way to control any aircraft. What has resulted is a complete re-thinking of what goes on when controlling an aircraft.
When reading or discussing aviation there are many technical terms not always used correctly. A few new terms and some changed terms are used in an attempt to assure complete understanding.
This book presents ways to look at what is going on during flight from a pilot's perspective, how to control an aircraft. The design is to fly. The pilot controls.
The first five to ten hours of flight training should teach pilots’ aircraft control, after which they will learn what to do with the machine using that control.
What I have written I learned in just the past few years after going back into Instruction and dealing with those Instructors who each has their own understanding of how to fly. It's very interesting.
Such simple questions...
What makes an airplane go up? What causes an aircraft to stall? How do you steer an aircraft? How does an aircraft accelerate?
It may not be what you expected!
When is the last time you considered these basic questions? Do you really know the correct answer? Maybe you need to review some of the basics. I would like you to ask yourself if you are really aware of these things. I have written lots of the basic ideas into book form.
This website is a source for you to purchase and download a copy of my first book...if you don't want the book, look at the other information included here...there is more to come.
I feel it is important to any pilot out there to know what really stalls an airplane. You are the one that is controlling this thing. All machines have their limitations. If reached, most of those limitations can really bite.
Remember, it's just a machine. It is probably doing what you controlled it to do.
Bob Reser has flown for over fifty years as both a commercial and military pilot. He has flown a variety of aircraft and holds ratings in several large aircraft. Additionally Bob has done flight instruction and managed flight instructors for several years.
Bob holds ATP in Boeing 727, 757, 767, 747-400, DC-10 and B-25. His first commercial flying job was single pilot B-25 dropping on forest fires in Alaska with only 300 hours total time. He flew U.S.A.F. and Air National Guard transport (C-123), observer (O-2), and jet fighter (RF-84, F-89, F102) aircraft for 20 years while flying the commercial airline very large transports for 30 years. Bob also holds USAF Navigator and Radar Observer ratings.
How did Bob fly the B-25 at 300 hours? It’s all about opportunity. If it was available (affordable), you could initially learn while flying a Boeing 777.
250 all jet flight training in the Air Force, 50 hours C-123 with the Air Guard. His first propeller airplane had two R-2600 reciprocating engines. His first light aircraft flight was after 350 hours, soloing an Aeronca Champ after one turn around the pattern. His CFI was obtained after 4 hours in the Champ! Haven't times changed? Has the physics of aircraft control changed??
Most of the years working, Bob commuted from his farm hayfield to the Air Guard and his Commercial Airline job with his own private aircraft.
For several years after airline retirement, he worked as Vice-President of Safety for a large flight school.
A personal aircraft mishap from which Bob survived with only minor burns and injuries confirmed his idea of the considerations for surviving an off-field landing, even a crash.
The later years when working at the flight school, with ongoing review of Instructors, Students, and Examiners, the ideas professed of how to control flight were formed, there began an idea that something is missing in the general knowledge of aircraft control.
The past few years Bob has been working on this book while professing the need for a changed approach to basic flight training. | aerospace |

A Lockheed-Boeing Co. joint venture has had a lock on the work for six years. SpaceX, which showed twice this year it could get to the International Space Station, is now trying to break into the business of launching U.S. military and spy satellites.
The Lockheed-Boeing venture, United Launch Alliance, has launched “hundreds of billions of dollars” of satellites on 66 consecutive missions, said Robert Stevens, Lockheed’s chairman and chief executive officer.
“I’m hugely pleased with 66 in a row from ULA, and I don’t know the record of SpaceX yet,” Stevens said at a Dec. 14 Bloomberg Government breakfast in Washington. “Two in a row?”
“Cost doesn’t matter at all if you don’t put the ball into orbit,” he said. “You can thrift on cost. You can take cost out of a rocket. But I will guarantee you, in my experience, when you start pulling a lot of costs out of a rocket, your quality and your probability of success in delivering a payload to orbit diminishes.”
All of SpaceX’s Falcon 9 missions have reached orbit and “completed all primary mission objectives,” Musk said in an e-mailed statement. The Air Force last month awarded the Hawthorne, California-based company two trial launch missions.
On the cost issue, Musk said: “The fundamental reason SpaceX’s rockets are lower cost and more powerful is that our technology is significantly more advanced than that of the Lockheed-Boeing rockets, which were designed last century.” | aerospace |

Keywords: unmanned aerial vehicle, UAV test field, camera sensors, geometric quality parameters, workflow
Abstract. The geodetic-photogrammetric test field at the industrial monument Zollern colliery in Dortmund offers a scenario for carrying out geometric and radiometric tests of UAV systems. The foundation for this builds a geodetic precision network (position and height accuracy approx. 2 mm) with a total of 45 ground control points, distributed over an area of approx. 7 hectares. Within the scope of a campaign carried out in autumn 2017, various UAV sensor systems were tested under comparable conditions. Within this paper geometric investigations of two current DJI cameras, Zenmuse X4S (20 Mpix) and X5S (20.8 Mpix), as well as a Phase One IXU 1000 (100 Mpix) are presented. While the Zenmuse cameras reflect the current state of development of the manufacturer DJI, the medium format camera system from Phase One is primarily settled in the classic aerial segment. However, the desire for increased measurement accuracy (e. g. for engineering applications) also makes such a high-performance sensor interesting for UAV applications.
In addition to the configuration of the test field, the system comparison requires identical parameters for flight planning, in particular image overlapping, a complete cross flight configuration at different flight altitudes and the definition of a uniform ground resolution (GSD = 14 mm).
The investigations show clear differences in the achievable quality of the cameras. Though the high-priced Phase One system shows the best results, the most cost-effective system, the Zenmuse X4S, delivers only slightly worse results. In contrast, the Zenmuse X5S performs significantly worse than the other systems, mainly resulting from the mechanically unstable camera concept with interchangeable lenses. Finally, the comparison of the software products Pix4D Pix4Dmapper, Inpho UASMaster by Trimble and Agisoft PhotoScan partly shows significant differences in the results of image orientation. In particular in settings with sparse GCP usage the results vary considerably, indicating different strategies on how the residuals are distributed and the datum is defined, mostly Pix4Dmapper outperforms the others. In better GCP configurations there is no significant difference between Pix4mapper and Agisoft PhotoScan, while UASMaster does never deliver the best results. | aerospace |

Whether you want to pilot a mini-quadcopter or you’re interested in something larger and more advanced, the drone market has something for you, but it’s important to understand the parts of a drone before trying to get your hands on one. Below are the basic components that makeup commercially available drones:
Consumer drones are powered by electric motors, and some use custom brushless DC motors or frameless BLDC motors that are available from drone manufacturers and hobby stores. Of course, if you’re looking for aerospace BLDC motors for more advanced applications, you’ll want to contact a brushless DC motor manufacturer by visiting https://www.arcsystemsinc.com.
The reason brushless motors are used in drone technology is that these types of electric motors tend to last longer due to less contact between moving parts. Additionally, a DC brushless motor will usually have a higher torque-to-weight ratio. This latter bit is important for pushing drones at higher speeds while limiting drag due to weight.
The batteries that power consumer drones need to have enough power to achieve and maintain flight without weighing the craft down. This has been a challenge for drone engineers and is part of the reason why consumer drones are not able to stay in the air for hours at a time. Current flight times for consumer drones can be as long as 30 minutes or so on one battery charge, but enterprise drones can put out enough power to stay aloft for around an hour.
When it comes to battery life, the number of features can make a difference. In addition to the actual flight controls of the drone, radio communication, lights and other onboard features all require power. The more features that are in use at any given time, the less flight time the drone can achieve per charge. The upside to this design, however, is that rechargeable lithium-ion batteries can be swapped out easily to get a drone back in the air quickly.
The external components of a drone include things like propellers, landing gear and the body of the drone itself. Additionally, drones often include cages around propellers to offer protection in the event of a crash. Most of these pieces are made from plastic since polymer materials are lightweight and offer enough durability to withstand rough handling.
Video cameras may also be attached to some drones for recording flights. These components interact with the internal electronics to either store video to an onboard SD card or transmit a video feed to a nearby receiver. Currently, drone cameras can achieve 4K fidelity, but many record in 1080p.
The internal components of a drone are the things that control elements like speed and lift. An onboard flight controller board receives a signal from a nearby transmitter that a pilot uses to send commands to the drone. These commands are digitally converted and instructions are sent to the propellers and any other external components used to achieve flight doithuong.
Electronic speed controllers and electronic stabilization components may also be built into a drone. These components interface with one another and with the instructions sent by the pilot’s transmitter to determine what adjustments need to be made to propeller speed, direction and angle. Wiring harnesses may be used to quickly connect and disconnect certain components for drone customization, and fasteners are also sometimes included inside consumer drones to allow users to change out pieces like landing gear elements and cameras. | aerospace |

Now that we live in a world where boarding an airplane and flying across the country – or even the world - is simply a part of everyday life, the wonder of flight has diminished for many. Despite this, physics students from all around continue to delight in the many physical forces that play a part in keeping these huge objects (like jumbo jets) from falling out of the sky!
The common explanation given to those curious about how an airplane wing produces lift uses the Bernoulli Principle. This is the concept that because of the airfoil shape of a wing, the air traveling over the top of the wing must travel faster than the air going under the wing because it has to travel a farther distance. The resulting difference in pressure between the two (higher pressure under the wing) creates lift, keeping the plane in the air.
This explanation is unsatisfactory in a number of ways. It does not consider or explain the important role that the angle of attack plays in flight, nor does not explain how planes can fly upside down (where according to the Bernoulli Principle, the pressure would actually be higher on the top of the wing, pushing the plane down to the ground!). For some interesting arguments and calculations refuting the Bernoulli Principle as a sound explanation for lift in an airplane, check out Gail Craig’s book “Stop Abusing Bernoulli! How Airplanes Really Fly” available from Regenerative Press (see bibliography).
Although the Bernoulli Principle is used to describe many physical phenomena, it does not explain lift. Luckily for us there is a much more sound explanation for how an airplane flies! There are four main forces that act on an airplane wing during flight: lift, weight, thrust, and drag. To further explain the physical phenomena that lift a plane during flight, I will instead use Newton’s Laws.
Let’s say a plane is flying at a constant velocity and is not changing in altitude. Newton’s first law states: “Any object at rest will remain at rest or an object in motion will remain in motion unless a force acts on it.” Newton’s second law tells us that the sum of the forces (F) acting on a body is the mass (m) times the acceleration (a) of the body. In the case of our airplane, there is no acceleration because the velocity does not change up or down, forwards or backwards, so the sum of the forces must be zero. (F = ma = 0) In the case of the up and down forces, we know that the weight of the plane is acting down, so the counteracting lift force must be of magnitude equal and opposite the weight (which can be very large depending on the size of the airplane in question)!
First, we must clarify that air does not fly over an airfoil as smoothly and as straight as is commonly depicted. Let’s take a little detour to look at air as a fluid to explain how the shape of an airfoil diverts air down. When a moving fluid such... | aerospace |

The purpose of the flight was to establish compliance with the demanding regulatory and safety systems necessary for future unmanned flight in France. During the exercise the demonstrator performed a 30 minute flight successfully executing a variety of flight patterns before landing in an autonomous mode. The unmanned air vehicle was piloted and monitored from the ground station located at the base.
The VSR700 demonstrator has been flying autonomously since May 2017 with a safety pilot as part of its development programme. The diesel engine installed to meet naval and military requirements has been fine tuned during this period and the automatic flight control systems have been developed to meet the new regulatory standards. This new critical operational capability is pursuing its development plan and 2019 will see the rollout of the prototype. | aerospace |

SpaceDaily.com is reporting that Russia has ordered a doubling of production on their Soyuz and Progress model spacecraft. This comes as a direct result of the inability of NASA to return the shuttle to service.
Russia says it is leading a group of vested nations in calls for a full crew of six aboard the International Space Station by 2009, and it's willing and able to make that happen.
Meanwhile NASA continues to grapple with credibility issues regarding, among other sordid things, a space transport system that just can't seem to get off the ground...

In October a subscale demonstrator for India’s secretive Ghatak stealth drone was spotted recently during a trial. A video and images of the demonstrator called Stealth Wing Flying Testbed (SWiFT) have recently surfaced.
However, the Indian Ministry of Defense or the Defense Research and Development Organization (DRDO) has not issued an official statement, which is fully responsible for the project.
In terms of appearance, the SWiFT corresponds, broadly, with previous artist’s concepts and scale models of the drone and, more generally, of those of the Ghatak, with which it shares a flying-wing planform and an engine intake located above the forward fuselage. While the trailing edge of the drone is difficult to make out, it appears to have a classic tailless flying wing profile, providing an overall arrowhead shape, rather than the highly cranked wing found on other stealthy drones, such as the Northrop Grumman X-47B. Its trailing edge is less swept than other designs, like Russia’s S-70, for instance. It is said that the shape of this UAV will serve as the overall design idea of the future Ghatak UAV. | aerospace |

Xcor Aerospace, a California aerospace company, plans to enter the space tourism industry with a two-seat rocket ship capable of suborbital flights to altitudes of more than 60 kilometers above Earth.
The spacecraft, called The Lynx, is about the size of small private plane, and is expected to fly in 2010. It will take off from a runway like a normal plane, and reach a top speed of Mach 2 and an attitude of 60,000 meters. Then it would descend in a circling glide to a runway landing.
How much will it cost to get up there? Well, the ship will be flown by two pilots and carry up to six passengers, who will pay about U.S. $200,000 each. Apparently passengers will experience 4.5 minutes of weightlessness and will be able to unbuckle themselves to float in the cabin before returning to Earth. | aerospace |

However speeches at El Palomar Air Brigade I were prudent arguing that even when recovering the Falklands/Malvinas is a permanent goal for Argentina and its Air Force, it will be achieved through dialogue and diplomacy.
The ceremony was headed by the Air Force Chief of Staff, Brigadier General Enrique Victor Amrein together with the head of the Joint Forces Chief of Staff and commanders of the other forces, Defense officials, national and local authorities, military personnel and special guests.
The battle for our sovereignty must take place in international forae, with dialogue and diplomacy, said Brigadier General Amrein adding that the force´s motto is to defend the motherland, yesterday, today and always.
A fighter pilot during the 1982 conflict, Amrein recalled his comrades who had the courage and will to defeat Britain during the 1982 conflict.
In effect on May fist, Vulcan bombers and Sea Harriers begun to bomb Stanley and Darwin landing strips, but Argentina which had invaded and occupied the Falklands by force in 2 April, reacted by sending bombers and fighters to combat the British effort.
According to the Air Force, 57 sorties were completed and 20 tons of bombs dropped, but also the first Argentine Air Force members to lose their lives in combat were recorded.
Both sides experienced heavy losses, and by the end of the conflict June 14, Argentina, had lost most of its aircraft and 55 airmen, mostly pilots.
During the ceremony retired Brigadier Norberto Dimeglio, Malvinas veteran and pilot of a Mirage V Dagger from the first squadron to make contact with the British, spoke recalling the first day of combat and fellow pilots.
Retired Brigadier Eduardo Daghero then read the roll call of pilots and those killed in combat, which was followed by a minute of silence.
A fly-past of a Hercules C-130 and several A-4AR Fighting Hawk, and the parade of several hundred personnel closed the ceremony. | aerospace |

The VIRB 360…
Once pilots get their multirotors operating well, and start actually doing things with it other than tearing holes in the sky, one of the first hurdles faced is increasing the available flight time. Most pre-packaged, ready-to-fly multirotor models come with a battery pack that will only last from 8 to 10 minutes of normal flying. For many, this is long enough, but for others that wish to do aerial photography, survey work or other professional type applications, there is always a desire to extend the flight times. Getting flight times in the 20 to 30 minute range is achievable with many multirotors that are available today, but there is a bit more to it than simply strapping more batteries on the model. In this months installment of Multirotor Flight we will take a look at how to maximize the efficiency of the multirotor power system in order to get the longest possible flight times.
First and foremost, there are a few basics about flight that must be considered. Number one is the fact that “Lighter Always Flies Better”. This is especially true in multirotors since the weight of the machine takes a certain amount of power to hold in the air. Heavier machines require more power and therefore they will have shorter flight times than lighter machines.
The second major thing to consider is the fact that larger props are more efficient than smaller props at converting rotational energy into thrust. This is because larger props can move larger volumes of air more efficiently.
The third thing to consider is slower turning props are more efficient at creating thrust that faster turning props. Props are essentially little wings going round and round generating lift. Basic aerodynamic principles show that the drag on a wing increases exponentially as speed increases, and this is the same with props. Props that are spinning faster have greater drag losses than slower spinning props, and this robs a model of flight time.
Finally, the efficiency of the motors and speed controllers themselves will play a role in the overall efficiency of the power system and can have a big impact on the flight time of a multirotor. Now that each of the components of the efficiency equation have been introduced, let’s take a closer look at each one and how it affects the overall flight time of multirotor aircraft.
Weight is always a factor in considering flight times for electric powered models of any kind. Design engineers will always say, “Design an aircraft to fly, not to survive a crash”. There is always a trade-off between structural strength and weight when designing aircraft. All aircraft must be built strong enough to survive any of the forces they will see in the air, but also be able to handle a bit of “hanger rash” and the occasional not-so-perfect landing without falling apart. Modern carbon fiber composites, light-weight aluminum alloys and molded plastic parts work together in many multirotor frames available today providing an airframe that is not only strong, but also light weight. The best starting point to maximize flight times is to use as light a frame as you can to get the job done.
Another consideration in the weight part of the equations is the total weight of the power system. Careful attention needs to be paid when selecting motors to make sure they are matched to the power that is actually needed to do the job. If a machine needs motors capable of producing 200 watts each, and larger motors capable of producing 400 watts are used, the total weight of the multirotor will be higher than necessary and this will require more power to keep the craft flying. Always remember, lighter always flies better, and also longer!
Next let’s take a look at how propellers factor into the flight time and efficiency of multirotor power systems. Larger props will always be more efficient than smaller props, because they move a larger column of air downwards as the props rotate. From 7th grade geometry class, we all know that the area of a circle is equal to Pi times the radius squared. For a 10 inch diameter prop, the cross sectional area of the column of air moved down by the propeller is equal to 3.14159 x 5 x 5 or 78.5 square inches. If you go to a 14 inch prop, then the area is equal to 3.14159 x 7 x 7 or 153.9 square inches or roughly double that of the 10 inch prop. With the larger 14 inch prop, you only have to move the air downward at half the speed to move the same volume of air compared to the 10 inch prop. Since less energy is required to accelerate the air, less current is pulled from the battery and flight time increases.
Prop efficiency is commonly expressed in the number of grams of thrust created per watt of power consumed by the motor, such as 8.5 g/W. The higher this number is, the more efficient the prop is at converting the rotational energy of the motor into thrust. Figure 1 shows a chart of the efficiencies of several different size props running on the same motor. Each of these props is spinning at an RPM that produces 500 grams of thrust. As can be seen from the data, the larger props turn at a lower speed to generate the thrust AND require less power to do so. When you take the grams of thrust created, and divide that by the number of watts used by the motor, you get the efficiency factor of that prop at one specific thrust value.
From this data, you can quickly see how prop diameter affects flight time. If you had a quadcopter that weighed 2000 grams (4.4 pounds) you would need to make 500 grams of thrust from each motor to hold the craft in a stable hover. From the chart you can see that the 10 inch props have an efficiency of 9.08 grams per watt while the 14 inch props have an efficiency of 11.55 grams per watt. This is an increase in efficiency of 27%, so all other things being equal, switching from 10 inch props to 14 inch props would give you an increase in flight time of 27%. Of course, this is assuming that the motors are actually capable of running the larger props without exceeding the maximum current rating of the motor. In some cases, it is necessary to use a lower Kv motor to have the torque needed to spin the larger prop without exceeding the motors maximum current recommendations.
If this data is taken one dimension further, we can see how rotational speed affects the efficiency of propellers. Props act much like wings from an aerodynamic standpoint. The parasitic or skin friction drag of any wing increases as a function of the square of the speed. Because of this, if a prop is rotating at twice the speed, the drag is 4 times higher. Figure 2 shows a set of data collected with a brushless motor running on 4 Li-Po cells with an APC 12×4.5 Multirotor prop. This table shows the performance of the motor over its full range of operation at throttle settings from 20% up to 100% throttle. From this chart, if a graph is created that plots prop efficiency versus throttle position the data set will look like the one shown in Figure 3. From this graph, if the machine is hovering at 50% throttle the efficiency of the props is approximately 8.2 grams per watt. At 40% throttle this value increases to about 9.3 grams per watt, and at 60% throttle it decreases to 7.2 grams per watt. If your multirotor is heavier, not only do you have to generate more lift to keep it flying, the props are also less efficient at producing thrust, so you get hit even harder on the current draw from the battery. On the other hand, if your machine is lighter, you need less power and the props are working more efficiently which contributes to longer flight times.
The final part of the equation is the actual power system itself. Higher quality motors that are made with better grades of materials will be inherently more efficient than cheaper motors using inferior components. If you have one motor that has an efficiency of 80% compared to another motor that has an efficiency of 90% there is a huge difference between the two. At first glance some will say that one motor is 10% more efficient that the other. The truth is that one motor is twice as efficient as the other! If you look at the inefficiency of the motors, the 80% efficient motor is 20% inefficient and the 90% efficient motor has an inefficiency of only 10%. The inefficiency is what causes the losses in the motor. The motor that is 80% efficient has double the losses of the motor that is 90% efficient, and will cost you flight time across the board.
The other thing to consider in power systems is the voltage that the motors are running at. The electrical losses in a power system are directly related to the current flowing through the system. From Ohm’s law we know that power is equal to voltage times current. Voltage can also be expressed as current times resistance, so if we substitute this for voltage, power can also be expressed as current times current times resistance, which is commonly called “I-Squared-R”. This is why electrical losses in a system go up as a function of the square of the increased current.
When we consider total power in a system, we normally figure Volts x Amps. In a 3-cell power system (11.1 volts) if we are pulling 20 amps all together, the total power is 222 watts. In a 6-cell power system (22.2 volts) we can get the same power from only 10 amps. If the wiring in a power system had a resistance of 0.1 ohms, the total power losses in the 3-cell system would be 20 x 20 x 0.1 or 40 watts. In the 6-cell system, the power losses would be 10 x 10 x 0.1 or only 10 watts. This is why higher voltage power systems are inherently more efficient. In this example switching the power system from 3-cells to 6-cells cuts the electrical loses by 75%!
Batteries are another important consideration when calculating flight times on multirotors. In many cases, the batteries make up the highest percentage of the payload weight of the craft. Quite often, pilots make the mistake of thinking that adding a second battery will double the flight time. This is incorrect for 2 reasons. First, when a second battery is added, the overall weight of the aircraft increases, and this requires more power to hold the craft in a hover all the time. The other thing that people forget to consider is the fact that the props also operate less efficiently at the higher loading, so the efficiency takes a double hit! In most cases, adding a second battery will not double the flight time, but will instead give a 70 to 75% increase in flight time. Each additional battery has a smaller impact in the increase of flight time, and eventually a point is reached where adding another battery will actually decrease the flight time due to the high weight and lack of efficiency in the power system.
When all of these different aspects are combined, it is possible to double the flight time of a multirotor by simply optimizing every part of the power and propulsion system. Putting all of these different considerations together, you will get the longest flight times from a multirotor if you start with the lightest airframe possible, use the largest props that will fit on the frame and power them with high quality, low Kv motors, using higher voltage battery packs. Hopefully this information will help to get the power system in your multirotor optimized for the longest possible flight times and allow you to get the maximum benefit from your multirotor power system. | aerospace |

Sailors aboard the USS John Finn successfully detected, tracked and targeted the rocket with an SM-3 Block IIA missile during a test off the west coast of Hawaii, the Missile Defense Agency (MDA) said in a statement.
The successful operation comes after two failed intercept tests, in June 2017 and January 2018.
A test firing in February 2017 had been successful.
“This was a superb accomplishment and key milestone for the SM-3 Block IIA return to flight,” MDA Director Lieutenant General Sam Greaves said.
The MDA in January said America had so far spent about $2.2 billion on the system and Japan about $1 billion. The MDA could not immediately confirm if those numbers had grown.
The SM-3 Block IIA missile is part of the AEGIS Ballistic Missile Defense system and is made by arms giant Raytheon. | aerospace |

He is also an Air Force Veteran.
Armon was born in Stuart, Florida, graduated from Jenson High School, and enlisted in the United States Air Force. He says, “I like to serve others and I wanted to serve our country and be around like-minded individuals as well because it’s always motivating to surround yourself with people who share your goals.”
Armon’s first duty station was at NAS Pensacola, where he went to tech school to study and learn about the newest F-35 jet. It was the Air Force College of New recruits where he learned about all the composites on the aircraft and then worked on the jets by adding and removing material to help the jets become more covert to radar.
Armon then relocated to Hill Air Force Base in Utah and continued to work on the F-35 jets, installing devices to make the jets stealthier and more undetectable by radar. He says, “Stealth will be ‘hugely important’ for the next-generation Air Force fighter, but it will also be important to see how the next aircraft integrates its sensors and its command-and-control capabilities. It's also speed, low observability, different ways of collecting data, and different ways of transmitting and protecting all of the transmissions because it is a way of breaking ‘kill chains,’ which is a Military concept that identifies the structure of an attack. Conversely, the idea of breaking an opponent’s kill chain is a method of defense or preemptive action, which is why being stealthy is so important. Whether you're sitting in an airplane or flying an unmanned aircraft, as long as we break the kill chain sometime between when you arrive in the battlespace and when the enemy weapon approaches your airplane, you're successful at using stealth."
Armon lived on base when he served at Hill Air force base. He recalls, “It was very cold there. I’m used to the warm Florida weather, but I would have to get up at 5:30 AM to be at work by 7:00 AM. We had roll-call and then we were assigned to different aircraft and different airmen who we would be working with that day, and we would collect our gear and equipment and go to work in the hanger with the F-35 avionic crew chiefs. Every day was different, and I liked that. It was always a surprise. We would take our lunch break at the Dining Facilities Administration Center where they had everything you could possibly imagine to eat and we also ate there for breakfast and dinner if we wanted to, but we were also allowed to go off base to restaurants as well. After work, I would usually study the Career Development Course for Low Observational Structural Maintenance. I got an award for ranking as one of the highest scorers on the test!”
Armon then helped the crew chiefs fuel the jets and put chalk on the outside of the wheels, so the jets didn’t move. He applied resin and paints as smoothly as possible so radar wouldn’t bounce off the material. He then used stencils to brand the Pilot’s name, Unit, and Base on the aircraft. He decided to get into Real Estate in his spare time while he was on active duty.
Armon met his future wife, Brooke, while at Hill Air Force Base. Brooke worked with both the Military and Civilians helping them with all of their documents. Armon says, “I was hanging out with my friends in a dorm room, and she walked in. It was love at first sight for me and we got married in 2021 and moved to Ft. Pierce, Florida. Because Brooke was training to become a Nurse, we decided to move to Pensacola to be closer to her college and I became a full-time Realtor. I got my MRP Certification because I know what it’s like to work with other Military members and their families, and I wanted to extend my help and service to them. Seeing that smile on my clients' faces when they see their dream home is priceless, which is why I want to be part of their dream.”
Armon’s service areas are Pensacola, NAS Pensacola, Navarre, Gulf Breeze, Ensley, and West Pensacola.

MetadataShow full item record
As of 2014, the space servicing market has a potential revenue of $3-$5B per year due to the ever-present interest to upkeep existing orbiting infrastructure. In space servicing, there is a delicate balance between system complexity and servicer capability. Basic module-exchange servicers decrease the complexity of the servicing spacecraft, but is likely to require a more complex architecture of the serviced satellite (the host) in terms of electrical and mechanical connections. With increasing dexterity of the servicing satellite, host satellites can remain closer to flight-proven heritage architectures, which is a practice commonly adopted to increase reliability of space missions. This increased dexterity is provided through the on-orbit exchange of end-effector tools appended to a robotic arm. The dynamic coupling between such an arm and the satellite base has been the subject of intense academic scrutiny and its understanding is essential to the success of robotic servicing missions. In this work, we address different phases of a servicing mission using the dual quaternion formalism. First, we propose a dual quaternion pose-tracking controller that adaptively estimates the mass properties of a spacecraft using either a continuous-time implementation of the concurrent learning framework, or a discretized implementation. The advantage of incorporating concurrent learning lies in enhancing the parameter convergence characteristics of the adaptation scheme. Next, we provide the derivation of the dynamic equations of motion for a spacecraft with a serial robotic manipulator. This derivation uses a Newton-Euler approach formulated in dual quaternion algebra. This model is subsequently adapted to perform end-effector pose stabilization and end-effector pose tracking using the Differential Dynamic Programming control framework. A generalization of the dual quaternion-based framework for modeling of spacecraft with a rooted tree topology and five different types of joints is provided. The formulation is validated on a two-arm robotic spacecraft. This model is then used to implement a generalizable modification to the concurrent learning algorithm that allows “aggressively” estimating the 77 parameters that compose the mass properties of the rigid bodies in the two-arm multibody system. | aerospace |

They won’t know for sure until a scheduled communications pass at 8.30am [BST] on Sunday 17 July. Here’s the latest image of Vesta taken by Dawn on 9 July at a distance of about 26,000 miles (41,000 km).
NASA’s Dawn spacecraft obtained this image with its framing camera on July 9, 2011. It was taken from a distance of about 26,000 miles (41,000 kilometers) away from the protoplanet Vesta. Each pixel in the image corresponds to roughly 2.4 miles (3.8 kilometers) Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA
And from the JPL press release
When Vesta captures Dawn into its orbit, engineers estimate there will be approximately 9,900 miles (16,000 kilometers) between them. At that point, the spacecraft and asteroid will be approximately 117 million miles (188 million kilometers) from Earth.
“It has taken nearly four years to get to this point,” said Robert Mase, Dawn project manager at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “Our latest tests and check-outs show that Dawn is right on target and performing normally.”
Engineers have been subtly shaping Dawn’s trajectory for years to match Vesta’s orbit around the sun. Unlike other missions, where dramatic propulsive burns put spacecraft into orbit around a planet, Dawn will ease up next to Vesta. Then the asteroid’s gravity will capture the spacecraft into orbit. However, until Dawn nears Vesta and makes accurate measurements, the asteroid’s mass and gravity will only be estimates. So the Dawn team will need a few days to refine the exact moment of orbit capture.
The BBC report has a great quote
Initially, Dawn will be about 16,000km (9,900 miles) from the asteroid, but this distance will be reduced over time.
Mission scientists hope to get within 200km of the surface but the team do not intend to take any unnecessary risks.
“We would like to get as low as possible but if we crash Dawn, Nasa would understandably be very angry at us,” Principal Investigator Chris Russell told BBC News.

Update Dawn has confirmed that it has entered orbit around Vesta, the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter. | aerospace |

Researchers have named this probe IceMole, and as Space.com explains, “After IceMole reaches its target — a cryovolcanic crevasse filled with water it is hoped — it aims to sample the liquid, examining it for evidence of microbes.”
This exploration project, called the Enceladus Explorer, or EnEx, launched on February 22, but testing of the IceMole is already underway here on Earth. It has successfully been used to drill into glaciers in Switzerland, and researchers plan to conduct additional testing during the next couple years in Alaska and Antarctica.
According to Oliver Funke, project manager for the Enceladus Explorer at the German Aerospace Center, “EnEx deals with one of the most exciting tasks of space exploration — the search for extraterrestrial life.” Funke also stated that, if EnEx goes well, an IceMole mission to explore the polar ice caps on Mars will be proposed.

Five things to know about the Wright-Patterson Air Force Base in Dayton, Ohio.
Amanda Rossmann, Cincinnati Enquirer
CINCINNATI — Wright State University advised its campus community to stay away from areas near the north end of campus late Thursday as emergency personnel respond to reports of an active shooter at Wright-Patterson Air Force Base.
“Wright State Police have become aware of multiple reports that Wright-Patterson Air Force Base Police are responding to an active shooter incident on base and have initiated lock-down procedures,” the university said in a Facebook post on Thursday night.
Emergency personnel responded to a report of an active shooter at the National Air and Space Intelligence Center in Area A around 9:25 p.m., according to a Twitter post from the base.
“Security Forces are currently sweeping the building,” the base tweeted. “The base is on lockdown.”
As of 11:40 p.m., the base’s “Giant Voice” alert system was warning personnel to “take cover and remain in your offices until lockdown is heard.”
The base underwent active shooter training in August, according to its website. During that training, the base command center used Giant Voice to notify personnel that the entire installation was under lockdown.
“All of our military and civilian employees are trained to quickly assess the situation and take appropriate action,” the base said in a follow-up tweet at 10:57 p.m.
In 2018, an unknown individual called 911 believing an active shooter drill at the Wright-Patterson Medical Center was the real thing, prompting security forces to descend on the hospital building and sweep to clear the hospital.
The National Air and Space Intelligence Center, is the Department of Defense’s “primary source for foreign air and space threats,” the base’s website states. The center reports directly to the deputy chief of staff for Intelligence, Surveillance, Reconnaissance, and Cyber Effects Operations.
Wright-Patterson Air Force Base is located approximately 11 miles northeast of Dayton, Ohio. As the largest single-site employer in Ohio, it boasts an annual economic impact of $4.2 billion, with a workforce comprised of over 30,000, including military, civilians and contractors. | aerospace |

While the first agency skillfully performed its functions of organizing space missions, the European rocket industry was steadily floundering in place. This was partly due to a lack of funding, and partly due to a series of conflicts within the organization arising from different visions of ELDO.
This situation would remain unchanged until 1975, when the newly created ESA began its launch vehicle development program. This step would not only guarantee Europe a certain level of independence in conducting space missions, but also brilliantly prove Europe’s prowess in the global market of space launches.
Fantastic Four: the start of the Ariane series
A few years after its creation, ESA took the first steps to develop its own rocket program. With the support of the French National Space Agency (Centre National d’Etudes Spatiales, CNES), the agency began refining the concept of the L3S rocket proposed by the French back in 1973.
In fact, the L3S was a refined modification of the Europa IIIB rocket. The Europa series of rockets was a long-term development of ELDO started back in the 1960s. Its first modifications consisted of three stages, each of which was produced by three different European countries. The first stage was taken from the British Blue Streak rocket. The second, Coralie, was of French origin. West Germany was responsible for the development of the third stage, Astris. However, at the test stage, both Europa modifications (first and second) demonstrated a 100% failure rate, as all five test runs ended in failure. The proposed third modification of the rocket, which was called Europa IIIB, initially received the green light for its development, but was later deemed too expensive, and was put on the shelf until better times. Those times came with the advent of ESA.
Hence, the L3S was designed to completely make up for Europa’s failures. After six years of development, in 1979, the first three-stage launch vehicle, Ariane 1, appeared in ESA’s arsenal. From the beginning, Ariane intended to deliver commercial satellites and cargo into orbit. This was different from the standard purposes for which rockets were built. In most cases, space launches were conducted by military rockets that were converted for orbital launches, which made ESA’s approach innovative.
The debut launch of the Ariane 1 took place on December 24, 1979 during the mission L-01, when the rocket delivered its payload of the CAT (Capsule Ariane Technologique), designed to track all stages of its flight, into GEO. The equipment installed on the CAT not only contained sensors for pressure, temperature, and stress resistance, but was also itself a facsimile satellite payload. The Ariane 1 brought it into geosynchronous orbit 202 at 35,753 km.
The first stage of the rocket housed four Viking-5 propulsion engines developed by the French manufacturer Société Européenne de Propulsion. The second stage of the rocket had an additional Viking-4 engine. The final third stage was equipped with an HM7-A engine made by Snecma (now Safran Aircraft Engines). It ran on liquid oxygen and liquid hydrogen propellants. ESA realized that this thruster design worked very well, allowing it to remain almost unchanged on the first four generations of the rocket, until the debut of the two-stage Ariane 5 in the late 1990s.
Success of the Ariane 1 mission was spectacular. It put an end to America’s long-running dominance in the market of launching commercial payloads into orbit – from now on, Europe would also be in the running for these contracts. The European Ariane 1 could adequately compete with the American launch vehicles, since the volume of its payload compartment allowed place several spacecraft there at once, significantly reducing the cost of their delivery into orbit.
In March 1980, ESA and the French CNES founded the rocket building company Arianespace, which has since managed the development and creation of future versions of the Ariane.
Great hopes were placed on the potential of Ariane 1. However, they fell into doubt during the rocket’s first commercial launch (and fifth launch overall) for the L5 mission. An anomaly with the turbo pump on the third stage of the rocket led to an interruption in communication with the rocket eight minutes after launch. The rocket suffered a critical failure and lost its payload, leaving a big stain on the reputation of the newly formed Arianespace.
This was the second unsuccessful launch for Ariane 1, but it turned out to be the last, as the rocket will not fail again in the future. The error statistics would almost be acceptable, except the rocket had a total of 11 space launches (thus giving the Ariane 1 a failure rate of about 19%). The first unsuccessful commercial mission also raised questions about the feasibility of creating disposable rockets as such, as the debut of the US Space Shuttle deprived Arianespace of some contracts.
The situation was improved by the interest in the rocket of the satellite telecommunications consortium Intelsat. By 1984, Ariane 1 had flown two missions (L-7 and L-8) deploying Intelsat V F-7 communications satellites. It was these contracts that allowed Arianespace to build ten rockets to launch. During one of these launches, the historic ESA Giotto mission went to Halley’s Comet. However, the trend towards increasing weight of satellites over the course of the 1980s required modernization of the rocket.
The Ariane 2 project was started in 1979, simultaneously with the development of Ariane 3, which even made its debut two years before the second edition of the series. Thus, the third Ariane began flying in August 1984, while the second first lifted off in May 1986. At the same time, Ariane 2 was able to deliver 375 kg more cargo to geostationary orbit: 2175 kg compared to 1800 kg for Ariane 1.
Ariane 3 had even more power, equipped with two SEP P7.35 side boosters, which were used for the first 27 seconds of flight. The boosters helped to increase the payload capacity of the rocket by another 500 kg, upping it to 2700 kg for geosynchronous transitional orbits. In addition, the rocket’s failure rate improved significantly: out of 11 launches, the Ariane 3 experienced an error only once.
Getting over the the 2+ ton payload limit was very important for Ariane — by the end of the 1980s, when the second and third Ariane were decommissioned, the series had become the undisputed world leader in the class of heavy launch vehicles.
From 1988 to 2003, the Ariane 4 continued the glorious traditions of its predecessors. During this period, the rocket carried out 116 space missions, 113 of which were successful. The success rate of 97.4% was the best among all versions of Ariane, even including the subsequent incarnation of the rocket.
The payload capacity of the rocket was almost twice that of its predecessor: various modifications of the Ariane 4 (there would be six of them in total) could deliver from 2,000 to 4,800 kg of cargo into geosynchronous orbit, and from 5000 to 7600 kg into low Earth orbit. This power was achieved first and foremost due to the modernization and increase in the number of lateral solid-fuel boosters, which appeared back in the days of the Ariane 3. The combination of engines using both liquid and solid fuel was a novelty for European rocketry. A similar design solution was used at that time in the Chinese space program.
The Ariane 4 was truly indispensable for Europe, as made clear by the fact that almost the entire ESA joined the development of the rocket. It was financed by the governments of Belgium, Denmark, Spain, Ireland, Italy, the Netherlands, Germany, Great Britain, France, Sweden, and Switzerland. During its lifetime, Ariane 4 not only performed many commercial flights, but also launched outstanding ESA science missions, including Hipparcos astrometric satellite, as well as the Meteosat series of meteorological satellites.
To service the flights of the new rocket, the new ELA-2 launchpad was built at the French cosmodrome in Kourou, which ensured the possibility of carrying out up to eight launches of the heavy rocket per year. This put the ESA second in the early 1990s only to the Soviet Union in terms of launch capacity.
New Ariane 5 concept and Ariane 6 delay
In terms of engineering, Ariane 4 was the quintessence of the design embodied in the first rocket of the series. It made no sense to try further improving this technology, so during the start of development of Ariane 5 in January 1985, a radically new concept of rocket vision was introduced.
This first of all meant reducing the number of stages to two, plus auxiliary side boosters. The first (or main cryogenic stage) ascended using various modifications of Vulcain rocket engines. The second stage was equipped with one EPS rocket engine (Etage à Propergols Stockables; English: Storable Propellant Stage, SPS), which operated on a fuel mixture of monomethylhydrazine (MMH) and nitrogen tetroxide.
The main innovation of the EPS engine was the ability to perform re-ignition, demonstrated in October 2007, during the V26 mission.Two P24 solid side boosters were also attached to the Ariane 5, each weighing 277 tons (including fuel) and providing an initial thrust of 7,080 kN.
From the beginning, the Ariane 5 was developed specifically for the needs of manned launches, in particular the Hermes spacecraft proposed in the 1980s and 1990s. This was a significant departure from past Ariane modifications, which were designed to launch commercial satellites into orbit. The Ariane 5 handled its task well: different versions of the rocket could accommodate up to two large (SYLDA payload system) or three slightly smaller main satellites (SPELTRA system). A modification equipped with the ASAP payload platform was able to deploy eight smaller secondary link satellites at once.
In a single flight, the Ariane 5 could deliver significantly more payload to orbit (up to 10.8 tons per GTO in the EKA modification) than the Ariane 4 at an average of a 20% lower cost
But even despite the cost reduction and greater power, not everyone at ESA representatives was happy about the proposals to completely replace the almost flawless Ariane 4 in favor of the fifth generation, which, moreover, had to be developed from scratch. Because of this conflict of views, Great Britain was not involved in the development of Ariane 5. However, 20 other ESA member countries contributed to the construction by involving their contracting firms.
The first launch of Ariane 5 took place in 1996, but it was a failure due to a software error in the rocket’s navigation system. This bad experience would not be repeated, however, as between 2003 and 2017, the Ariane 5 conducted a record series of 82 successful space launches in a row. In total, during the entire life of the rocket’s program from 1996 to 2023, Ariane 5 performed 117 launches, of which 112 were successful (for an overall success rate of 96%).
ESA began developing a replacement for Ariane 5 while the rocket was still in service. The main goal of the new carrier was to increase the number of annual rocket launches from 6-7 to 11 launches per year. The current proposal is for the Ariane 6 to have two main modifications: one with two (Ariane 62) and another with four (Ariane 64) solid-fuel boosters for the acceleration phase of the flight. Both models will be aimed at delivering cargo to Sun Synchronous Orbit (SSO) and Translunar Injection (LTO). The Ariane 6 may debut during the implementation of the Artemis Agreement, a program launched in the United States to develop a permanent presence of humans on the moon.
The sixth-generation Ariane was supposed to start flying from 2020, but the latest statements from the ESA indicate that the rocket will not fly until after 2024. Recently, the European Agency again postponed the phase of its test trial, without giving specific reasons for its decision. It is likely a result of financial difficulties, as in meeting after meeting, European ministers cannot agree on a plan for the further development of the heavy rocket project.
To a certain extent, the multi-year production delay risks making Ariane 6 obsolete, as the rocket does not offer the ability to return its stages to Earth, and it still uses a fuel mixture based on liquid hydrogen and liquid oxygen (hydrolox), while many players in the market are increasingly trying to convert their propulsion systems to liquid methane fuel. In 2010, CNES attempted to start development of an alternative reusable booster based on Ariane 6 that could run on methane fuel, but as of 2015, ESA had questioned the benefit of this rocket design.
On November 23, 2023, Ariane 6 nevertheless conducted a long-term static fire test. This is one of the last checks that is done before a full-fledged first test launch, and it turned out successfully. The Vulcan 2.1 engine lasted 2 minutes 42 seconds, short of the 470 seconds ESA was preparing for.
Until Ariane 6 gets off the ground, ESA remains without its own heavy rocket. Fortunately, since the late 1990s, the European Space Agency has begun developing an alternative series of lower-capacity launch vehicles.
Introducing VEGA: A reliable lightweight?
In the 1990s, Arianespace announced the creation of another rocket. The main purpose of the new carrier was to fill the niche for delivering small payloads, mainly to polar and sun-synchronous Earth orbit.
The small-capacity rocket appeared was named Vega (Italian: Vettore Europeo di Generazione Avanzata). The project was developed with the participation of specialists from the Italian Space Agency (ASI), which provided the lion’s share (almost 65%) of the financing. France’s CNES also joined the production with a 13% share. Spain, Belgium, the Netherlands, Switzerland and Sweden also took part in the development of the first generation of the Vega.
Some design solutions were borrowed from Ariane, but Vega used three main stages plus an upper AVUM module involved in adjustment maneuvers in the final stages of the rocket’s flight. The first three stages of the rocket are powered by solid-fuel engines manufactured by the Italian company Avio, and the upper AVUM module is a spacecraft powered by a Ukrainian-made RD-843 liquid engine.
The development of the rocket began in 2003 and lasted more than eight years. The first Vega flew on February 13, 2012. ESA recognized this launch as highly successful, and of the subsequent 21 launches of the first Vega modification, 20 were successful.
However, the next modification of the rocket, the Vega-C, would not enjoy the same success. Its second launch in December 2022 was a failure, with a nozzle design error on the Zefiro-40 second stage engine resulting in the loss of two Airbus Pléiades Neo Earth satellites. The future operation of the rocket was in jeopardy.
After the investigation, ESA put further Vega-C production on hold, proposing a complete modification of the AVUM upper stage and the introduction of a new engine design that would run on liquid oxygen and liquid methane cryogenic fuel. This decision led to the termination of Ukraine’s participation in the project. The production of components is now taking place exclusively in EU countries, primarily by German companies. According to the latest forecasts, the easy-to-use Vega-C can last until the end of 2024.
And while Ariane and Vega are on hiatus, the European launch vehicle market is presenting other replacement options. Britain’s Skyrora, along with Germany’s RFA and ISAR Aerospace, offer their own solutions for LEO and polar orbit with the aim of attracting both commercial customers and ESA itself. Some of these companies are ready not only to show new concepts of rocket technology, but also to ensure that Europe has its own fleet of space carriers.
Spaceships and Transporters: Hermes and ATV
From its very inception, the ESA was aimed at carrying out unmanned space missions. European astronauts reached space most often by the efforts of the US and the USSR, which had the undisputed leadership in delivering people into orbit.
However, the first concept for the production of a European spacecraft was developed by the French CNES back in 1975, after which it immediately received interest from the young ESA. The ship was named Hermes, and was very similar in design to the American Space Shuttle.
In 1985, ESA named the French aerospace company Aérospatiale as the main contractor for the project, which completed the first phase of development of the new vehicle in six years. However, at the beginning of the second phase, which included production and the beginning of missions, the project slowed down dramatically.
To some extent, ESA’s rapprochement with the Russian space agency in the 1990s contributed to the delays. Hopes for cooperation with the Russians forced the Europeans to abandon their glider spacecraft design in favor of a capsule-type transporter (it was this type of transport that was required for joint projects). In the end, the Hermes project was deemed unsuitable, and the ESA focused its efforts on developing another carrier.
In 1995, ESA made a new proposal to facilitate the operation of the ISS, in order to meet the logistical needs of the International Orbital Station. In 1998, the European Agency concluded a contract worth $470 million again with the French Aérospatiale. ATV (Automated Transfer Vehicle) cargo spaceships developed by the company delivered supplies to the ISS from 2008 to 2015. During the ATV-2 mission (known as “Johann Kepler”), ESA even delivered a record-breaking seven tons of supplies and scientific equipment.
A quarter of a century after the death of Eduardo Amaldi, who stood at the origin of the ESA, in March 2012 ATV-3 — an automated European-made transport ship named after the scientist — docked with the ISS. In addition to useful cargo and scientific equipment, he brought the same “letter of hope”, a visionary manuscript authored by Amaldi, written by a scientist 1958, where he expressed his thoughts on the creation of a space agency in Europe. This symbolic event summed up Europe’s decades of efforts to achieve a permanent presence in space.
Today, ESA is serious about renewing its program to deliver commercial cargo into orbit. During the November meeting at the European Space Summit in Seville, Spain, ESA management announced the competition for the project of a space cargo ship, which should deliver cargo to the ISS until 2028 inclusive. It is likely that the new ESA cargo ships will try to take their place in delivering cargo to the future commercial stations that are supposed to replace the ISS after 2030.
According to the competition plan, contracts for the production of a new space transporter with a total cost of $80 million can be distributed between two or three participating companies. Such an approach will guarantee Europe additional confidence that at least one of the executors will present the project of a working spacecraft on time. So far, none of the European companies have been approved to participate in the competition, but it is known that Exploration (it is working on a series of capsules to send one of them to the ISS as early as 2027) and the German Rocket Factory Augsburg (RFA ), which recently announced a collaboration with Atmos Space Cargo and OHB to create a space vehicle.
Time will tell if ESA will still be able to offer new solutions for vehicles to meet the logistical needs both at the level of orbital stations and for the delivery of cargo for Europe’s future presence on the Moon. Given its past experience, the space agency has every chance to realize these ambitions. | aerospace |

SEATTLE, March 12, 2015 – Boeing [NYSE: BA] recently completed the first flight of a NATO Airborne Warning and Control System (AWACS) aircraft with modern flight deck and avionics systems that replace 1970s-era analog systems.
During the two-hour flight on Dec. 31 testers evaluated five full-color glass displays with customizable engine, navigation and radar data. The systems performed better than expected and the program will now enter an extensive flight test qualification phase. Fourteen NATO AWACS in total will receive the flight deck modernization, delivery of the first upgraded aircraft is scheduled for January 2016.
“These improvements provide NATO with an AWACS fleet that will save time and fuel and will also decrease operational costs by allowing a reduction in the flight crew size,” said Jon Hunsberger, Boeing AWACS program manager.
The upgrades ensure compliance with current and future air traffic control and navigation requirements, giving the aircraft broader access to airspace around the world. They also resolve recurring issues involving out-of-production avionics by using commercial, off-the-shelf digital avionics. The AWACS is based on the Boeing 707.
The upgrade to the first NATO AWACS, as well as for a U.S. Air Force AWACS aircraft, is part of a $394-million Air Force contract awarded in 2012. First flight of the upgraded U.S. AWACS is expected in 2016.
Thirteen additional NATO AWACS will receive installation of the upgrade as part of a $257 million modification effort. Those modifications begin in 2016 and will be completed by 2018.
“The AWACS program is a model for enduring transatlantic defense cooperation,” said Brian Moran, president, EU & NATO relations. “Boeing is honored to enhance this critical capability for the Alliance in close collaboration with industry partners from across Europe and the United States.”

4 Wing Cold Lake, Canadian Armed Forces
F-15 Eagles from the 142nd Fighter Wing arrive in Yellowknife, Northwest Territories, for Exercise Vigilant Shield 2017, Oct. 17, 2016. Vigilant Shield 17 represents a unique opportunity to practice and hone joint interoperability and cooperation skills between Canada and the United States in order to protect borders as well as national interests. (U.S. Air National Guard photo by Senior Master Sgt. Shelly Davison, 142nd Fighter Wing Public Affairs).
Aircraft, personnel and equipment from the Canadian Armed Forces and the United States Air National Guard have deployed to Yellowknife, N.W.T. as part of Exercise VIGILANT SHIELD 17 from October 17 to 21, 2016.
The North American Aerospace Defense Command (NORAD) led, bi-national exercise aims to deploy and conduct air sovereignty operations in the far north and the high Arctic, thus demonstrating a combined ability to detect, identify and meet possible threats in some of the most remote regions in the world.
“This exercise is an outstanding opportunity to demonstrate our shared bi-national, NORAD role,” said Major Tristan McKee, the Canadian Detachment Commander in Yellowknife for Exercise VIGILANT SHIELD 17.
“This is one of a series of times, through progressively more complicated exercises over the past few years, where aircraft and personnel from both Canada and the United States can come together to operate and support each other successfully at multiple forward operating locations. Practicing these combined operations is a key goal of Exercise VIGILANT SHIELD 17.”
Deployed to Yellowknife in support of this exercise are F-15 Eagles and personnel from the 142nd Fighter Wing of the United States Air National Guard, based out of Portland, Oregon. Alongside them are personnel and equipment from a variety of Royal Canadian Air Force locations, primarily from 4 Wing Cold Lake.
This exercise provides a forum for NORAD to practice its ability to deploy to a variety of locations across vast distances, yet still support and achieve a complex set of missions and objectives.
Canadian and American military personnel are deployed to a number of other locations in Canada, such as 5 Wing Goose Bay, Inuvik, N.W.T., and Canadian Forces Station Alert, Nunavut. NORAD forces are commanded by Canadian NORAD Region Headquarters in Winnipeg, Man. and coordinated through the Canadian Air Defence Sector at 22 Wing North Bay, Ont.
Deployed assets across the entire exercise include: CF-18 Hornet, CH-149 Cormorant, CC-130H Hercules, F-15 Eagle, F-22 Raptor, E-3 Sentry, KC-135 (USAF) Stratotankers and hundreds of necessary maintenance and support personnel required for sustained flying operations. The participants can also count on the Canadian Army who deployed personnel to the various exercise locations to provide security support.
NORAD is a bi-national command formed by a partnership between Canada and the United States that provides aerospace warning, aerospace control and maritime warning in defence of North America. | aerospace |

(RepublicanNews.org) – The Russian Su-34 fighter jet is a twin-seat aircraft used to strike enemy targets in the air and on the ground, day and night, under “any weather conditions.” Although the jet is one of the more advanced planes at Russia’s disposal, it has a history of problems, with multiple crashes on record just this year.
On October 17, video of a Su-34 crash surfaced on social media, showing the jet hitting a residential building and starting a fire that killed at least 13 people, including three children. The accident happened in Yeysk, Russia, just south of the port city of Mariupol, Ukraine. Both pilots ejected before impact.
At least 13 reported dead in Russia after military plane hits building https://t.co/mXD9av8xkc
— The Guardian (@guardian) October 18, 2022
The Russian Defence Ministry said the jet had just taken off from the Yuzhny airbase when an engine fire started, causing the crash. Footage of the incident seems to verify the aircraft was traveling away from the airbase, and satellite footage showed multiple Su-34 jets on the same military base.
An impromptu interview with one of the surviving pilots confirmed there was no enemy fire shooting the craft out of the air. US Council on Foreign Relations (CFR) security expert J Andrés Gannon said the video indicates an engine malfunction. Another expert, Paul Beaver, conjectured a missile might have hit the plane.

The company has concluded the auction for some of its assets, which were put up for sale as part of its Chapter 11 bankruptcy proceedings. Altogether, the three winning bids come to around $36 million.
The winning bids were submitted by Rocket Lab, Launcher (and its parent company, Vast), and Stratolaunch. According to court filings, Rocket Lab will get Virgin’s 144,000-square-foot Long Beach, California–based manufacturing facility for $16.1 million; Launcher successfully bid for the Mojave-based facilities for $2.7 million; and Virgin’s “Cosmic Girl” aircraft and related assets will go to Stratolaunch for $17 million.
“As Virgin Orbit embarks on this path, the management and employees would like to extend their heartfelt gratitude to all stakeholders, including customers, partners, investors, and employees, for their support and dedication over the years,” the company said in a statement. “It is through their collective efforts that the Company has been able to achieve significant milestones and make lasting contributions to the advancement of satellite launch in the United States and the United Kingdom.”
Stratolaunch had submitted a “stalking horse” bid for the modified Boeing 747 aircraft earlier this month. A stalking horse bid sets the minimum floor price for the assets, so it appears that Virgin did not receive any competing bids for that property.
Virgin Orbit filed for Chapter 11 bankruptcy protection on April 4 after months of bad news: In January, a failed rocket launch from Cornwall, U.K., followed by an announcement that it was furloughing most of its staff due to insufficient capital. The company entered bankruptcy after it failed to secure additional funding to continue operations.
Virgin — to be distinguished from Virgin Galactic, a company that launches humans into space — had developed a novel way of sending small payloads into orbit using a modified Boeing 747 jet and a small rocket called LauncherOne. According to some estimates, Virgin Orbit spent upward of $1 billion developing the modified jet and rocket launch system.
All in all, the winning bidders are getting a steal. Rocket Lab already has a massive footprint in Long Beach, and it will only benefit from the additional square footage and machines, like 3D printers and specialty tank welding machines. Vast, which has ambitions of launching the first private space station, will get the Mojave leases for test stands and an aircraft hangar. And Stratolaunch, the company purchasing Cosmic Girl, is getting the plane for just a small fraction of its development price.
“The combination of [Virgin’s] assets with Rocket Lab’s existing production, manufacturing, and test capabilities is expected to advance the production of Rocket Lab’s larger launch vehicle, Neutron,” Rocket Lab said in a statement. “Rocket Lab will not be integrating Virgin Orbit’s launch system within its existing launch services.”
According to court filings, the final sale hearing is scheduled for May 24 at 2 p.m. EDT. | aerospace |

News 1 - NASA’s Juno spacecraft completed fourth Jupiter flyby
NASA’s Juno spacecraft made the fourth flyby over Jupiter. Juno was about 2,670 miles (4,300 kilometres) above the planet's cloud tops and traveling at a speed of about 129,000 mph (57.8 kilometres per second) relative to the planet.
