Question by NONAME: Artificial Gravity on Spacecraft Questions.?
It seems to me so much work has been done on bone loss and other physiological aspects of long term spaceflight that (analyzing the published data) nothing can compare to induced artificial gravity. I guess most of us have heard of a spinning compartment allowing a 1-G environment to overcome the physiological problems of long term weightlessness, when, say, traveling to Mars.
Assuming bearings and seals could be made to function and be lubricated sufficiently well as to not fail under the adverse conditions of deep space; should we not retake a look at this revolving system? Is two years too long a time for this system to function without failing?
My question is this… With modern computing systems as good as they are, could not the whole spacecraft spin like a bullet to give 1-G, with the computers taking star sightings at attitudes determined at intervals and compute course corrections? And, would this not help the physiological problems? It seems that NASA and other countries’ Space Agencies shy away from such ideas siting cost as their main concern, yet spend billions on none productive research. Why is this?
Astronauts could shower (wash clothes, even) and remain fit and strong, especially when they eventually return from their long journey.
What are your thoughts on 1-G space traversing ?
Helge P. I would appreciate thoughtful input from a grown-up. Re-reply in a few years, eh.
permative: Forgive me. I did err here. I meant, in hindsight to say the research is ground based (Packing for Mars: pages 211-228) and my text was based on these pages.

Centrifuges. Big fucking centrifuges.
