This is why sending humans to Mars is stupid - at least in our current resource and energy constrained world. Humans requires suits, food, air, water, health support, housing, massive infrastructure to return back and so on. On the other hand, they don't contribute much more in terms of sensors or agility. I know most of you are now super uncomfortable reading this and you want to be poetic and tell me all about spirit of adventure and what not. But get this: We need to make best out of our resources and technologies. We can have self driving cars and robots working in warehouses and delivering pizza. Why do we really need humans on Mars? I'm all of sending humans to Mars once we have found almost unlimited resorvoir of enery and world GDP has increased to point where we don't know what to do with all the excess. But until then let's send 100s of robots to mars, let's survey as much land there as possible, may be establish robot colony there, send robots with more and better sensors. May be robots can even build there biosphere first over years to prepare arrivals of humans. That would be much better use of our limited resources.
