Mind you, I'm not against research in either drugs or mechanical solutions (better exercise machines), but they could serve as backup in case the main system - centripetal acceleration - is malfunctioning.
One question NASA has yet to answer is the minimal level of gravity necessary to prevent muscle and bone degradation. Is the Moon or Mars human-habitable in terms of gravity? If that's not the case, then mission plans would have to include rotating habitats for planetary surfaces, which makes matters a little more complex.
- AndrewKemendo 11y agoYou're joking right? A quick google search returns hundreds of resources from nasa.gov about research into bone and muscle degradation.
- coldtea 11y agoHundreds of resources from nasa.gov regarding research into bone and muscle degradation don't automatically translate to what the parent asked for, for NASA "to answer (...) the minimal level of gravity necessary to prevent muscle and bone degradation".
- AndrewKemendo 11y agoIt's probably the wrong question was my real point.
- eximius 11y agoIs there one? I imagine it is a proportional effect. You'd experience degredation at .9g, it just wouldn't be nearly as bad. The more interesting, and difficult I'd wager, is what is the minimum healthy level.
