Some scientists are finding more evidence of water on Mars, and some are pitching a differing explanation. In any case, I find it amazing that we have spacecraft orbiting another planet sending back huge quantities of data.
I hope we do find an active water-based ecosystem there with novel bacteria (or something similar). But it is interesting either way.
