I think it was one of the reasons it was created.

Interesting that the closer we look at Mars, the wetter (water ice) it gets. And if you have ice in quantity and a power source (reactors), one way trips are not only possible, but will quickly become the preferred solutions. Soil chemistry on Mars is still funky (perchlorates) and we have the unanswered question of what level of gravity does the negative impact of low-G kick in?

Mars is a third G; moon is a sixth. I would suggest that a variable-G facility for extended testing may be as important as developing reactors (and nuke rockets) for space settlement. Happily, the other bodies we might end up on permanently are either a third or a sixth-G. Gravity on asteroids approach zero-G. Cheers –
