Because Phobos has always the same face turned toward Mars, an electric propulsion system could be placed at the front to slow down the orbital speed.
But what would be the energy needed to supply the force of the propulsion system ?

1. ## integrate!
Hi I have problems integrating two questions, how do I integrate sqrt(x^2-4) / x? And (4lnx) / (x(1+(lnx)^2)? Thank you very much!!
2. ## Re: integrate!
For the second problem, first use t= ln(x), then use z = 1+ t^2. Hope this helps!
