That's kinda hard to just pull out that kind of money from Uranus.

In the early days, NASA did a lot of psychological testing to see how people would get along for extended periods of time in a small space. The result was not very good. It doesn't take long before the astronauts start disliking each other intensely. They don't talk much and try to avoid looking at each other. For one thing, they may stink for lack of bathing.

So, if you don't get along well with people here on earth, chances are you won't like going to Mars. (Not to mention the problems of going to the "bathroom" in zero gravity and the fact that the food is terrible, but that's another story.)

Yes, you can grow bone. I forgot to mention that the astronauts, after they came back, recovered almost all of their bone mass. However, the author stated that it doesn't come back the same as it was originally. It depends on which bones get stressed the most during exercise. It doesn't seem to come back on the hips very well because there's no good way to exercise or put stress on hips.

They experimented with dropping or banging the hip onto the floor from a height of about 4 to 6 inches. It worked a little but was not seen as being very effective. A word of caution: If a person has osteoporosis, they might break their hip if they try that.

So it seems the danger of breaking a hip, which could be life threatening, is still a problem, for those who have osteoporosis. I learned by reading that exercising doesn't build up all bones equally. Walking or jogging will help build up leg bones. Lifting hand weights will help build up arm bones etc.. (use it or lose it). Exercise the bones you wana keep healthy seems to be the rule.

By the way, if you lose bone mass and then gain it back, there's no way to tell if the bones are stronger or weaker than they were originally. And bone mass is not the same as bone strength; a big boned person could have weak bones while a small boned person might have strong bones.
