The crew seems to be walking right past an important thing: evidence of liquid water in the form of the sedimentary rock pile at right. Look at the pattern/texture on the rocks, indicating that at some time in the distant past (prior to their uplifting & jumbling), they were formed in a shallow body of water. WOW!
Oh, wait, this is just a painting, not a real video feed from Mars.
Seriously, I hope to see in my lifetime some evidence (via a robot proxy, most likely) of past or present life elsewhere in our solar system. I suspect that Mars is fairly dead now, but finding fossils there would be very awesome! (Heck, even sedimentary rocks as you've depicted would be really cool. Not just the layers we've seen, nor the beads of hematite, but actual rippled sand patterns.)
Of course, Jupiter's moon Europa might be our best bet for finding living things offworld. I hope I live long enough to witness that, if it's there...
(For the record, as vast as our universe is, I suspect--believe, actually--that there's life in a lot of places. But the scientist in me requires PROOF. I hope that we humans find it, soon, and in our own backyard would be very convenient!)
