No 'fun and games' at all because you have volunteers understand the risks up front with no bullshit. That the radiation shields are experimental and they'll likely be insufficient to prevent an involuntary sterilization at the least.
The understanding that, as the first out there, there's absolutely no chance of rescue should things go wrong.
But it's THE CHALLENGE of overcoming seemingly impossible odds with a reasonable chance of success that WILL find great people stepping up to willingly do so.
Without colonizing off this blessed rock and eventually beyond our solar system we're through when the next dinosaur-exterminating rock falls or even the Yellowstone volcanoes erupt as hard as some predict.
NASA had brave volunteers as well—no-one questions their courage.
The problem is that it is not “real” until somebody gets badly injured or dies in space or on the Moon (or Mars).
I don’t think the public is ready for it—even if the volunteers are.
We will find out soon enough.
My concern is the rush—there is some really great tech that is a couple of decades away that could make these missions hundreds of times less risky—nanotech shielding for all vehicles and spacesuits is one example.
I would also like to see robots land first and build and stock underground settlements—that would greatly reduce the risk to humans.
We will get it done eventually—I am not worried about that for one moment.
