Is muscle wasting a significant issue? Mars does have gravity, the people will no doubt be doing some physical work, so it won't be as bad as in orbit. On top of that, if they have no plans for ever coming back to Earth, then is there a significant downside to at least some atrophy?
- jahnu 11y agoIt's true that exercise does limit the loss and I guess you are right that it won't matter if you stay there. I suppose we just don't have enough data to say one way or the other. Edit: an old Nasa article on the topic... http://science.nasa.gov/science-news/science-at-nasa/2001/ast02aug_1/ http://science.nasa.gov/science-news/science-at-nasa/2001/as...
- jerf 11y agoCorrect. We know some things about how bad zero gravity is, we do not know how bad microgravity is. Given that it's probably a range (one presumes that .98G is probably medically indistinguishable from 1G, one presumes .02G is very like 0G though perhaps not quite indistinguishable), it's probably fair to say we are comprehensively ignorant.
