Quote from ares6
Mars is not full of water. There are evidence of ice caps on the poles of the planet. Nitrogen is rich with iron. Microbes exists. If we melt the ice caps, then we can create life and environment on Mars.
Well I didn't mean literally full of water, of course. There is frozen water on Mars, as well as CO2. I think the Martian atmosphere only has like 2-3% Nitrogen? Earth is like 78%. What do you mean Nitrogen is full of Iron?? What I am saying is that you can melt the ice caps, but that environment will not be able to be sustained long term because of a weak magnetosphere and lack of plate tectonic activity.
