+ NASA has lost contact with one its three spacecraft orbiting Mars, the agency announced Tuesday. Meanwhile, a second Mars orbiter is perilously close to running out of fuel, and the third mission is running well past its warranty.

+

Ground teams last heard from the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft on Saturday, December 6. “Telemetry from MAVEN had showed all subsystems working normally before it orbited behind the red planet,” NASA said in a short statement. “After the spacecraft emerged from behind Mars, NASA’s Deep Space Network did not observe a signal.”

+

NASA said mission controllers are “investigating the anomaly to address the situation. More information will be shared once it becomes available.”

That’s right—it’s the 2025 edition of our annual Charity Drive!

-

Every year since 2007, we’ve encouraged readers to give to Penny Arcade’s Child’s Play charity, which provides toys and games to kids being treated in hospitals around the world. In recent years, we’ve added the Electronic Frontier Foundation to our charity push, aiding in their efforts to defend Internet freedom. This year, as always, we’re providing some extra incentive for those donations by offering donors a chance to win pieces of our big pile of vendor-provided swag. We can’t keep it, and we don’t want it clogging up our offices, so it’s now yours to win.

-

This year’s swag pile is full of high-value geek goodies. We have over a dozen prizes valued at nearly $5,000 total, including gaming hardware and collectibles, apparel, and more. In 2023, Ars readers raised nearly $40,000 for charity, contributing to a total haul of more than $542,000 since 2007. We want to raise even more this year, and we can do it if readers dig deep.

+ SpaceX is planning to raise tens of billions of dollars through an initial public offering next year, multiple outlets have reported, and Ars can confirm. This represents a major change in thinking from the world’s leading space company and its founder, Elon Musk.

+

The Wall Street Journal and The Information first reported about a possible IPO last Friday, and Bloomberg followed that up on Tuesday evening with a report suggesting the company would target a $1.5 trillion valuation. This would allow SpaceX to raise in excess of $30 billion.

+

This is an enormous amount of funding. The largest IPO in history occurred in 2019, when the state-owned Saudi Arabian oil company began public trading as Aramco and raised $29 billion. In terms of revenue, Aramco is a top-five company in the world.

Those cases bring the outbreak total to 111.

-

The southern state’s outbreak now rivals outbreaks ongoing in Utah and Arizona, which have tallied 115 and 176 cases, respectively. The outbreaks are threatening to cost the country its measles elimination status, which was earned in 2000 after vaccination efforts stopped the virus from spreading continuously. If the current transmission of the virus isn’t halted by January, the virus will have circulated for 12 consecutive months, marking it once again as an endemic disease in the US.

-

In an update on Tuesday, South Carolina’s health department suggested the spread is far from over. Of the state’s 27 new cases, 16 were linked to exposure at a church, the Way of Truth Church in Inman. And amid the new cases, new exposures were identified at Inman Intermediate School. That’s on top of exposures announced Friday at four other schools in the region, which led to well over 100 students being quarantined.

+ A conservative group yesterday urged the Federal Communications Commission to take licenses away from NPR and PBS stations and let other entities use the spectrum. The request came from the Center for American Rights (CAR), a nonprofit law firm that has played a prominent role in the news-distortion investigations spearheaded by FCC Chairman Brendan Carr.

+

“In the wake of the wind-down of the Corporation for Public Broadcasting and the end of federal funding for NPR and PBS, the Center respectfully suggests that the Commission open an inquiry that looks at the future of ‘public’ broadcasting in that new environment,” a Center for American Rights filing said.

+

The CPB is set to shut down after Congress approved President Trump’s request to rescind its funding. The Center for American Rights said the CPB shutdown should be used as an opportunity to reassign spectrum used by NPR and PBS stations to other entities.

As companies race to turn fantasy into reality, they’ve developed a collection of tools to guide the development of generative AI. A cadre of major players in the AI race, including Anthropic, Block, and OpenAI, has come together to promote interoperability with the newly formed Agentic AI Foundation (AAIF). This move elevates a handful of popular technologies and could make them a de facto standard for AI development going forward.

-

The development path for agentic AI models is cloudy to say the least, but companies have invested so heavily in creating these systems that some tools have percolated to the surface. The AAIF, which is part of the nonprofit Linux Foundation, has been launched to govern the development of three key AI technologies: Model Context Protocol (MCP), goose, and AGENTS.md.

-

MCP is probably the most well-known of the trio, having been open-sourced by Anthropic a year ago. The goal of MCP is to link AI agents to data sources in a standardized way—Anthropic (and now the AAIF) is fond of calling MCP a “USB-C port for AI.” Rather than creating custom integrations for every different database or cloud storage platform, MCP allows developers to quickly and easily connect to any MCP-compliant server.

+ On Tuesday, French AI startup Mistral AI released Devstral 2, a 123 billion parameter open-weights coding model designed to work as part of an autonomous software engineering agent. The model achieves a 72.2 percent score on SWE-bench Verified, a benchmark that attempts to test whether AI systems can solve real GitHub issues, putting it among the top-performing open-weights models.

+

Perhaps more notably, Mistral didn’t just release an AI model, it released a new development app called Mistral Vibe. It’s a command line interface (CLI) similar to Claude Code, OpenAI Codex, and Gemini CLI that lets developers interact with the Devstral models directly in their terminal. The tool can scan file structures and Git status to maintain context across an entire project, make changes across multiple files, and execute shell commands autonomously. Mistral released the CLI under the Apache 2.0 license.

+

It’s always wise to take AI benchmarks with a large grain of salt, but we’ve heard from employees of the big AI companies that they pay very close attention to how well models do on SWE-bench Verified, which presents AI models with 500 real software engineering problems pulled from GitHub issues in popular Python repositories. The AI must read the issue description, navigate the codebase, and generate a working patch that passes unit tests. While some AI researchers have noted that around 90 percent of the tasks in the benchmark test relatively simple bug fixes that experienced engineers could complete in under an hour, it’s one of the few standardized ways to compare coding models.

A ruling for Trump would give him more power over the FTC and potentially other independent agencies such as the Federal Communications Commission.

-

Former FTC Commissioner Rebecca Kelly Slaughter, a Democrat, sued Trump after he fired both Democrats from the commission in March. Slaughter’s case rests largely on the 1935 ruling in Humphrey’s Executor v. United States, in which the Supreme Court unanimously held that the president can only remove FTC commissioners for inefficiency, neglect of duty, or malfeasance in office.

-

Chief Justice John Roberts said during yesterday’s oral arguments that Humphrey’s Executor is a “dried husk” despite being the “primary authority” that Slaughter’s legal team is relying on. Roberts said the court’s 2020 ruling in Seila Law made it “pretty clear… that Humphrey’s Executor is just a dried husk of whatever people used to think it was because, in the opinion itself, it described the powers of the agency it was talking about, and they’re vanishingly insignificant, have nothing to do with what the FTC looks like today.”

Twiki had Buck Rogers. And, of course, C-3PO and R2-D2 had Luke Skywalker. Now, in a scenario straight out of science fiction, MAPP will have whoever NASA names to the crew of the second Artemis mission to land on the moon.

-

The space agency has selected Lunar Outpost’s Mobile Autonomous Prospecting Platform, or MAPP, to become the first robotic rover to operate on the moon alongside astronauts. Although its tasks will be far simpler than those of the robots seen on TV and in the movies, the autonomous four-wheeled MAPP will help scientists learn more about the crew’s surroundings. Science instruments on the rover will characterize the surface plasma and behavior of the dust in the lunar environment.

-

“The Apollo era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets,” said Nicky Fox, NASA’s associate administrator for science, in a statement. “By deploying these… science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity’s interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon.”

+ Amazon has been updating the large-screened Kindle Scribe tablet more frequently and regularly than it updates its standard e-readers, and today the company is announcing the tablet’s third hardware update in four years. The regular Scribe is also being joined by a lower-end Scribe with less storage and no front light and an upgraded Kindle Scribe Colorsoft model with a color e-ink screen. This makes it only the second Kindle to include a color screen, after last year’s Kindle Colorsoft.

+

Both the regular Kindle Scribe and the Kindle Scribe Colorsoft are available to order starting today for $500 and $630, respectively. Both of those devices include a Premium Pen accessory and 32GB of internal storage; 64GB of storage is available for an extra $50 for both devices. The cheaper front light-less Scribe is coming sometime next year and will run $430 for a model with a more modest 16GB of storage. (These are all much more expensive than the original Scribe’s $340 launch price, but inflation, tariffs, and shortages are wreaking havoc with all kinds of tech prices for the past few years.)

+

The Scribe and Scribe Colorsoft both come with an updated front light “with miniaturized LEDs that fit tightly against the display,” narrowing the bezel and improving the uniformity of the lighting. Amazon has also tweaked the friction level of the paper-like texture on the glass display, shrunk the gap between the glass and the actual display panel to make writing on the tablet feel more like writing on paper, and added a quad-core processor and more RAM to speed the tablet up.

That order had called for the suspension of all permitting for wind power on federal land and waters pending a review of current practices. This led states and an organization representing wind power companies to sue, claiming among other things that the suspension was arbitrary and capricious.

-

Over 10 months since the relevant government agencies were ordered to start a re-evaluation of the permitting process, testimony revealed that they had barely begun to develop the concept of a review. As such, the only reason they could offer in defense of the suspension consisted of Trump’s executive order and a Department of the Interior memo implementing it. “Whatever level of explanation is required when deviating from longstanding agency practice,” Judge Saris wrote, “this is not it.”

-

Lifting Trump’s suspension does not require the immediate approval of any wind projects. Instead, the relevant agencies are likely to continue following Trump’s wishes and slow-walking any leasing and licensing processes, which may force states and project owners to sue individually. But it does provide a legal backdrop for any suits that ultimately occur, one in which the government’s actions have little justification beyond Trump’s personal animosity toward wind power.

+ Donald Trump’s decision to allow Nvidia to export an advanced artificial intelligence chip, the H200, to China may give China exactly what it needs to win the AI race, experts and lawmakers have warned.

+

The H200 is about 10 times less powerful than Nvidia’s Blackwell chip, which is the tech giant’s currently most advanced chip that cannot be exported to China. But the H200 is six times more powerful than the H20, the most advanced chip available in China today. Meanwhile China’s leading AI chip maker, Huawei, is estimated to be about two years behind Nvidia’s technology. By approving the sales, Trump may unwittingly be helping Chinese chip makers “catch up” to Nvidia, Jake Sullivan told The New York Times.

+

Sullivan, a former Biden-era national security advisor who helped design AI chip export curbs on China, told the NYT that Trump’s move was “nuts” because “China’s main problem” in the AI race “is they don’t have enough advanced computing capability.”

Those fell by the wayside as Google shredded its wearable strategy over and over, but gestures are back, baby. The Pixel Watch 4 is getting an update that adds several gestures, one of which is straight out of the Apple playbook.

-

When the update hits devices, the Pixel Watch 4 will gain a double pinch gesture like the Apple Watch has. By tapping your thumb and forefinger together, you can answer or end calls, pause timers, and more. The watch will also prompt you at times when you can use the tap gesture to control things.

-

In previous incarnations of Google-powered watches, a quick wrist turn gesture would scroll through lists. In the new gesture system, that motion dismisses what’s on the screen. For example, you can clear a notification from the screen or dismiss an incoming call. Pixel Watch 4 owners will also enjoy this one when the update arrives.

-

On Nov. 27, less than a week after COP30 ended, a powerful political bloc in Brazil’s National Congress, representing agribusiness, and development interests, weakened safeguards for the Amazon’s rivers, forests, and Indigenous communities.

-

The rollback centered on provisions in an environmental licensing bill passed by the government a few months before COP30. The law began to take shape well before, during the Jair Bolsonaro presidency from 2019 to 2023. It reflected the deregulatory agenda of the rural caucus, the Frente Parlamentar da Agropecuária, which wielded significant power during his term and remains influential today.

+ Although many of us associate it with rally-derived machinery from the late 1990s and early 2000s, these days, Subaru has mostly abandoned its performance cars to concentrate on its true calling—rugged, all-wheel-drive vehicles that are high on practicality, powered by horizontally opposed “boxer” engines. One area where the brand has never particularly excelled has been fuel efficiency, which is where today’s test car, the Subaru Forester Hybrid, comes in.

+

The last time Ars reviewed a Subaru Forester, it left us impressed. How about one with 40 percent better economy, in that case? Now, the 2.5 L flat-four engine operates on the Atkinson/Miller cycle, which generates 162 hp (121 kW) and 154 lb-ft (208 Nm). There’s an electric motor-generator starter and an electric traction motor with 118 hp (88 kW) and 199 lb-ft (270 Nm) that work together to send a combined 194 hp (145 kW) to all four wheels via a symmetrical all-wheel drive system and a planetary continuously variable transmission.

If that sounds vaguely familiar, that’s because it’s the same powertrain that Subaru has also fitted to the smaller Crosstrek Hybrid that we drove in September.

The only snag was that this didn’t match the recipe as described in historical texts. Now the same team is back with a fresh analysis of samples collected from a recently discovered site that confirms the Romans did indeed use hot mixing, according to a new paper published in the journal Nature Communications.

-

As we’ve reported previously, like today’s Portland cement (a basic ingredient of modern concrete), ancient Roman concrete was basically a mix of a semi-liquid mortar and aggregate. Portland cement is typically made by heating limestone and clay (as well as sandstone, ash, chalk, and iron) in a kiln. The resulting clinker is then ground into a fine powder with just a touch of added gypsum to achieve a smooth, flat surface. But the aggregate used to make Roman concrete was made up of fist-sized pieces of stone or bricks.

-

In his treatise De architectura (circa 30 CE), the Roman architect and engineer Vitruvius wrote about how to build concrete walls for funerary structures that could endure for a long time without falling into ruin. He recommended the walls be at least two feet thick, made of either “squared red stone or of brick or lava laid in courses.” The brick or volcanic rock aggregate should be bound with mortar composed of hydrated lime and porous fragments of glass and crystals from volcanic eruptions (known as volcanic tephra).

+ Heat-reddened clay, fire-cracked stone, and fragments of pyrite mark where Neanderthals gathered around a campfire 400,000 years ago in what’s now Suffolk, England.

+

Based on chemical analysis of the sediment at the site, along with the telltale presence of pyrite, a mineral not naturally found nearby but very handy for striking sparks with flint, British Museum archaeologist Rob Davis and his colleagues say the Neanderthals probably started the fire themselves. That makes the abandoned English clay pit at Barnham the oldest evidence in the world that people (Neanderthal people, in this case) had learned to not only use fire, but also create it and control it.

+

A cozy Neanderthal campfire

+

Today, the Barnham site is part of an abandoned clay pit where workers first discovered stone tools in the early 1900s. But 400,000 years ago, it would have been a picturesque little spot at the edge of a stream-fed pond, surrounded by a mix of forest and grassland. There are no hominin fossils here, but archaeologists unearthed a Neanderthal skull about 100 kilometers to the south, so the hominins at Barnham were probably also Neanderthals. The place would have have offered a group of Neanderthals a relatively quiet, sheltered place to set up camp, according to Davis and his colleagues.

So why should NASA undertake such a bold mission?

-

A new report published Tuesday, titled “A Science Strategy for the Human Exploration of Mars,” represents the answer from leading scientists and engineers in the United States: finding whether life exists, or once did, beyond Earth.

-

“We’re searching for life on Mars,” said Dava Newman, a professor in the Department of Aeronautics and Astronautics at Massachusetts Institute of Technology and co-chair of the committee that wrote the report, in an interview with Ars. “The answer to the question ‘are we alone is always going to be ‘maybe,’ unless it becomes yes.”

+ A single sperm donor who carries a rare cancer-causing genetic mutation has fathered at least 197 children across 14 countries in Europe, according to a collaborative investigation by 14 European news groups.

+

According to their investigative report, some of the children have already died, and many others are expected to develop deadly cancers.

+

The man—Donor 7069, alias “Kjeld”—carries a rare mutation in the TP53 gene, which codes for a critical tumor suppressor called protein 53 or p53. This protein (which is a transcription factor) keeps cells from dividing uncontrollably, can activate DNA repair processes amid damage, and can trigger cell death when a cell is beyond repair. Many cancers are linked to mutations in p53.

-

“Just being ready is the point, right?” Elba says. “It keeps people in check. Keeps the world straight. If they see how prepared we are, no one starts a nuclear war.”

-

There’s a lot that goes wrong in the film, namely the collapse of deterrence itself. For more than 60 years, the US military has used its vast arsenal of nuclear weapons, constantly deployed on Navy submarines, at Air Force bomber bases, and in Minuteman missile fields, as a way of saying, “Don’t mess with us.” In the event of a first strike against the United States, an adversary would be assured of an overwhelming nuclear response, giving rise to the concept of mutual assured destruction.

+ Rep. Haley Stevens (D-Mich.) filed articles of impeachment against Health Secretary Robert F. Kennedy Jr. Wednesday, accusing him of abusing the powers of his office and undermining public health, putting Americans’ lives at risk.

+

He “has got to go,” Stevens said in a video announcing the impeachment articles. In an accompanying press statement, she said Kennedy, who rose to prominence as an ardent anti-vaccine activist, “has turned his back on science, on public health, and on the American people—spreading conspiracies and lies, driving up costs, and putting lives at risk.”  She called him the “biggest self-created threat to our health and safety.”

+

It is very unlikely that an impeachment push will gain traction in the Republican-controlled Congress. No other Democratic lawmakers are backing the articles.

The Pebble Core Duo 2 and Core Time 2 are a natural evolution of the company’s low-power smartwatch designs, but its next wearable is something different. The Index 01 is a ring, but you probably shouldn’t call it a smart ring. The Index does just one thing—capture voice notes—but the firm says it does that one thing extremely well.

-

Most of today’s smart rings offer users the ability to track health stats, along with various minor smartphone integrations. With all the sensors and data collection, these devices can cost as much as a smartwatch and require frequent charging. The Index 01 doesn’t do any of that. It contains a Bluetooth radio, a microphone, a hearing aid battery, and a physical button. You press the button, record your note, and that’s it. The company says the Index 01 will run for years on a charge and will cost just $75 during the preorder period. After that, it will go up to $99.

-

Core Devices, the new home of Pebble, says the Index is designed to be worn on your index finger (get it?), where you can easily mash the device’s button with your thumb. Unlike recording notes with a phone or smartwatch, you don’t need both hands to create voice notes with the Index.

+ Nvidia, AMD, and Intel have all made high-quality image upscaling a cornerstone feature of their new GPUs this decade. Upscaling technologies like Nvidia’s Deep Learning Super Sampling (DLSS), AMD’s FidelityFX Super Resolution (FSR), and Intel’s Xe Super Sampling (XeSS) are all ways to transform a lower-resolution source image into a higher-resolution image, delivering better-looking games without requiring as much graphics hardware as you’d need to render the higher-resolution image natively. Later additions have focused on improving ray-tracing performance and “frame generation” technologies that boost frame rates by creating new AI-generated frames to insert between natively rendered frames.

+

Generally speaking, Nvidia’s DLSS technologies have provided better image quality than AMD’s FSR, but they have only been available on newer Nvidia hardware—the GeForce RTX 20-series or newer for most features, with frame-generation features locked to the RTX 40- and 50-series. FSR’s results don’t look as good, but they have benefited from running on just about anything, including older GPUs, Nvidia GPUs, and even integrated Intel and AMD GPUs.

+

Today, AMD is trying to shift that dynamic with something called “FSR Redstone,” a collection of ray-tracing and frame-generation features all intended to boost AMD’s image quality while being relatively easy to implement for game developers who are already using FSR 3.1 or FSR 4.

The deal includes HBO and the HBO Max streaming service but not WBD’s cable channels, which are to be split off ahead of the acquisition into a separate company called Discovery Global. Netflix said WBD’s split should conclude in Q3 2026.

After a grueling 24 races, the title was decided in a three-way fight by the finest of margins; just two points, less than half a percent, separated the winning driver from second place when the checkered flag waved on Sunday.

-

Coming into Abu Dhabi, McLaren’s Lando Norris was, if not a comfortable favorite, then at least the driver with the highest odds of prevailing. After a strong start to the season, the British driver’s form dipped at the Dutch Grand Prix. But he bounced back, retaking the championship lead from his Australian teammate Oscar Piastri in Mexico in October.

-

For much of the season, it seemed to be a two-car race. McLaren had a clear car advantage and two strong drivers, suggesting a repeat of the years we saw Lewis Hamilton and Nico Rosberg duking it out to bring home titles for Mercedes. But that didn’t figure on Red Bull developing its car late in the season. New boss Laurent Mekies has revitalized the energy drinks squad, and four-time champion Max Verstappen was able to close inexorably toward the McLaren drivers in the points with a string of sublime performances.

-

So imagine my surprise when, within two blocks of my first ride on the XPress 750, I had to pull off to the side of the street and lower the seat. This was especially notable given that the XPress is a budget bike (currently on sale for just under $1,000.00) that is only offered in a single frame size. So kudos to Lectric for giving me a comfortable and enjoyable ride, and doing so with a lot of features I wouldn’t expect at this price point.

-

That said, hitting that price necessitated some significant compromises. We’ll discuss those in detail so you can get a sense of whether any of them will get in the way of your riding enjoyment.

+ A measles outbreak that began in South Carolina at the start of October is showing no signs of slowing as officials on Tuesday reported 27 new cases since Friday. Those cases bring the outbreak total to 111.

+

The southern state’s outbreak now rivals outbreaks ongoing in Utah and Arizona, which have tallied 115 and 176 cases, respectively. The outbreaks are threatening to cost the country its measles elimination status, which was earned in 2000 after vaccination efforts stopped the virus from spreading continuously. If the current transmission of the virus isn’t halted by January, the virus will have circulated for 12 consecutive months, marking it once again as an endemic disease in the US.

+

In an update on Tuesday, South Carolina’s health department suggested the spread is far from over. Of the state’s 27 new cases, 16 were linked to exposure at a church, the Way of Truth Church in Inman. And amid the new cases, new exposures were identified at Inman Intermediate School. That’s on top of exposures announced Friday at four other schools in the region, which led to well over 100 students being quarantined.

-

On Tuesday, the European Commission announced that the social media giant had offered users an alternative choice of Facebook and Instagram services that would show them fewer personalized advertisements.

-

The offer follows an EU investigation into Meta’s policy of requiring users either to consent to data tracking or pay for an ad-free service. The Financial Times reported on optimism that an agreement could be reached between the parties in October.

+ Big Tech has spent the past year telling us we’re living in the era of AI agents, but most of what we’ve been promised is still theoretical. As companies race to turn fantasy into reality, they’ve developed a collection of tools to guide the development of generative AI. A cadre of major players in the AI race, including Anthropic, Block, and OpenAI, has come together to promote interoperability with the newly formed Agentic AI Foundation (AAIF). This move elevates a handful of popular technologies and could make them a de facto standard for AI development going forward.

+

The development path for agentic AI models is cloudy to say the least, but companies have invested so heavily in creating these systems that some tools have percolated to the surface. The AAIF, which is part of the nonprofit Linux Foundation, has been launched to govern the development of three key AI technologies: Model Context Protocol (MCP), goose, and AGENTS.md.

+

MCP is probably the most well-known of the trio, having been open-sourced by Anthropic a year ago. The goal of MCP is to link AI agents to data sources in a standardized way—Anthropic (and now the AAIF) is fond of calling MCP a “USB-C port for AI.” Rather than creating custom integrations for every different database or cloud storage platform, MCP allows developers to quickly and easily connect to any MCP-compliant server.

Prime Video dropped an extended teaser for the fifth and final season of The Boys—based on the comic book series of the same name by Garth Ennis and Darick Robertson—during CCXP in Sao Paulo, Brazil. And it looks like we’re getting nothing less than a full-on Supe-ocalypse as an all-powerful Homelander seeks revenge on The Boys.

-

(Spoilers for prior seasons of The Boys and S2 of Gen V below.)

-

Things were not looking good for our antiheroes after the S4 finale. They managed to thwart the assassination of newly elected US President Robert Singer, but new Vought CEO/evil supe Sister Sage (Susan Heyward) essentially overthrew the election and installed Senator Steve Calhoun (David Andrews) as president. Calhoun declared martial law, and naturally, Homelander (Antony “Give Him an Emmy Already” Starr) swore loyalty as his chief enforcer. Butcher (Karl Urban) and Annie (Erin Moriarty) escaped, but the rest of The Boys were rounded up and placed in re-education—er, “Freedom”—camps.

+ The Supreme Court’s conservative justices appear ready to overturn a 90-year-old precedent that said the president cannot fire a Federal Trade Commission member without cause. A ruling for Trump would give him more power over the FTC and potentially other independent agencies such as the Federal Communications Commission.

+

Former FTC Commissioner Rebecca Kelly Slaughter, a Democrat, sued Trump after he fired both Democrats from the commission in March. Slaughter’s case rests largely on the 1935 ruling in Humphrey’s Executor v. United States, in which the Supreme Court unanimously held that the president can only remove FTC commissioners for inefficiency, neglect of duty, or malfeasance in office.

+

Chief Justice John Roberts said during yesterday’s oral arguments that Humphrey’s Executor is a “dried husk” despite being the “primary authority” that Slaughter’s legal team is relying on. Roberts said the court’s 2020 ruling in Seila Law made it “pretty clear… that Humphrey’s Executor is just a dried husk of whatever people used to think it was because, in the opinion itself, it described the powers of the agency it was talking about, and they’re vanishingly insignificant, have nothing to do with what the FTC looks like today.”

I love roguelikes. Reader, I can’t get enough of them. If there’s even a whisper of a hot new roguelike on Steam, I’m there. You may call them arcane, repetitive, or maddeningly difficult; I call them heaven.

The second best part of video games is taking a puny little character and, over 100 hours, transforming that adventurer into a god of destruction. The best thing about video games is doing the same thing in under an hour. Beat a combat encounter, get an upgrade. Enter a new area, choose a new item. Put together a build and watch it sing.

-

If you die—immediately ending your ascent and returning you to the beginning of the game—you’ll often make a pit stop at a home base to unlock new goodies to help you on your next run. (Some people distiguish between roguelikes and “roguelites,” with the latter including permanent, between-run upgrades. For simplicity’s sake, I’ll use “roguelike” as an umbrella term).

+ B-9 had Will Robinson. Twiki had Buck Rogers. And, of course, C-3PO and R2-D2 had Luke Skywalker. Now, in a scenario straight out of science fiction, MAPP will have whoever NASA names to the crew of the second Artemis mission to land on the moon.

+

The space agency has selected Lunar Outpost’s Mobile Autonomous Prospecting Platform, or MAPP, to become the first robotic rover to operate on the moon alongside astronauts. Although its tasks will be far simpler than those of the robots seen on TV and in the movies, the autonomous four-wheeled MAPP will help scientists learn more about the crew’s surroundings. Science instruments on the rover will characterize the surface plasma and behavior of the dust in the lunar environment.

+

“The Apollo era taught us that the further humanity is from Earth, the more dependent we are on science to protect and sustain human life on other planets,” said Nicky Fox, NASA’s associate administrator for science, in a statement. “By deploying these… science instruments on the lunar surface, our proving ground, NASA is leading the world in the creation of humanity’s interplanetary survival guide to ensure the health and safety of our spacecraft and human explorers as we begin our epic journey back to the Moon.”
