why not die? (Score 3, Informative)

Why does he need to stay alive once he gets there? Can't he just walk around Mars and record what he sees and send it back to earth until he runs out of supplies and dies? I mean I would probably go to Mars and look around a place no one has ever been to if it meant I would be remembered as "that guy who went to Mars and just walked around until he died," and I'm only slightly insane. I bet you could find someone crazy enough to do it and still smart enough to keep the spaceship running.
