Growing potatoes on Mars, It is Possible.
Just a few years ago, NASA scientists told us they had found solid water, yes, ice, in the North Pole of Mars. With water, we have oxygen and hydrogen. We don't have to have an explosion like Matt Damon to grow potatoes.
I drew my ideas and put them on this website. I think humans can find suitable soil, enough water and oxygen on Mars, and build greenhouses. By the way, the light and temperature on Mars during the day are also quite suitable for plant growth.
