Question

Can plants be cultivated on planet Mars ?

Answer 1

I heard asparagus could work in that soil.  Of course it would have to be in an insulated structure.  Inside of a crater with a transparent bubble top would be ideal.

Answer 2

I think the atmosphere is so thin that (A) there wouldn't be enough oxygen for the poor little plants, and (B) there wouldn't be enough insulation provided by the atmosphere to regulate surface temperatures (and by that, I mean it would be super hot during the day and super cold during the night).
