Can The Human Body Handle Rotating Artificial Gravity?
Artificial gravity for spaceflight is a concept older than spaceflight itself, but we've only ever seen one small scale test ever flown in space. However decades of research have been performed to show that the human body can adapt to the conditions required for rotating artificial gravity.
@stux I guess the issue is what happens when we try and reach a far off planet and have to experience gravity again. Especially on a multi generational mission .
@zleap Even a few weeks or months like to Mars would be an issue with muscle and bone mass loss I think😮
Like people born on Mars, Martians would not be able to handle Earths gravity I guess
🇳🇱
The average time astraunauts spend on the ISS is 6 months, and they recover find for earht gravity. Longest time was 14 months and he too recovered just fine in earth gravity.
So while yes it is an issue, the current methods we have of handling it are more than enough to make it workable and "safe enough"
I did not say that 
For long term trips, like multigenerational, artificial gravity is a must.
But there are reasons its impractical. The gyroscopic effect would making changing directions of a craft with AG far more costly and stressful. We barely have enough fuel as is, if we added in AG due to the added fuel it would take to make course corrections it would be virtually impossible
The only way I would see it as being practical is multigenerational going from one star system to another.
If you go in a straight line from point a to b and only spin up at a and spindown at b, and both a and b are close to their respective suns, then its doable. You can harvest the energy via solar panels to do the spinup and down.
Could be helpful for something like mars since mars is probably still close enough to the sun that we can use socal energy to do the spin up and down.
@stux @freemo Ok i will watch the video, but I assume that it would be possible to adjust the gravty level if artificial, Tuvok did this on learning Curve (ST Voager) to help teach his recruits to be ready for any conditions. I think Mars has less gravity, it may be that you set the gravity closer to that of Mars or reduce slowly en route, so by the time you get there, you body has adapted.
@freemo @zleap
Oh yes! But the people on ISS have to workout for about 2 hours a day or so to keep up with the loss right
