comment Why did the Hubble telescope have to stay powered on while in storage?
I don't have any evidence to make a real answer but I believe that some of the instruments had to be temperature controlled. I is also likely that they wanted to keep the gyros running since there would be the chance of failure on startup.

Why, oh why would you bring that stuff back to Earth? Hasn't anyone seen Andromeda Strain?

comment Why is NASA buying expensive rockets from ULA when SpaceX is offering the same thing for almost half the price?
More cynically: political favors. It is good to order stuff from the territory of the senators who control your budget.

comment Spacesuit needed for 1 psi 100% methane atmosphere - 60 Fahrenheit?
The airlock would be a very big problem. since the atmosphere is 100% methane, the base will have to lose atmosphere every time it cycles the lock. Even if you burn methane in a controlled manner to generate the blow-out gas, you will still be using oxygen.

I think that the scale is on the order of the Earth becoming tidally locked to the ISS.

So, it would radiate faster than it would gain heat (assuming it wasn't deep frozen to begin with).

@Uwe, If the hotdog was in the shade, I think that it would free dry but in direct sun, I think that it will gain more heat than it radiates.

@IlmariKaronen, The images look OK to me. Maybe they've been fixed.
