Mars being the fourth planet away from the Sun really should be able so sustain some sort of life, do you agree?
I do, haven't they found water under the surface though?
They have found that it does have a fairly thin atmosphere, and features consistant with crater impact. I don't know if they found water however.
I wonder how hot it gets on mars.
I dont think it gets much hotter then earth if at all. The rotational and seasonal cycles are nearly identicaly to Earths, as well as the axis tilt that causes them.
