Sending people to Mars, and then what?

Will it be a "simple" round trip? The real problem is what to when you're there. Is there a base station? I don't see that happen before 2025. Maybe on the moon, but not on Mars. Maybe a return trip to Mars by 2025 or 2030, but not staying there.

Any round trip to Mars would require making the return fuel on site, correct?

If that's the case then just making a couple of unmanned return flights to test that seems it would take a decade.

A one-way ticket to Mars is certainly doable with current tech but unless we're sending Donald Trump I fail to see how we as a planet could get behind that concept.
