I don't think we have dealt with Mars problems at all, the road is still very long for any manned mission and I'm pretty sure the Moon will get its own base long before we even consider the possibility to explore Mars with humans. The base on the Moon being by itself a problem that we have not dealt at all. I mean we started space exploration like yesterday and each new problem seems to go on a logarithmic scale, they are hundred of times harder each time.
