Re: The Moon wins.
The current EMU's PLSS uses ice to cool the person inside.
I don't think you are the expert on comms on Mars. Neither am I, but I have read a dozen or so papers on the subject. The Moon has no chance to use propagation at low frequencies, Mars does. The Moon can't over time retain satellites without massive fuel reserves, Mars can use COTS Comms SATs or GPS.
Geoff, my point about the waste of time it would be trying to test Mars Systems at the Moon was directed at all the nonsense posted by the other lunies above your post... I was being lazy...
I think this Moon or Mars thing is all mute. Without a good political reason for going neither the Moon or Mars will soon be a target for NASA's Code M.
