Hey all,
I recently read a bit about proposals to induce "artificial gravity" on a mars mission by spinning two sections of a spacecraft on a long cable in order to create a centrifugal force that would simulate gravity by pulling astronauts outward toward the floor of their capsule, or, similarly, a space station that consisted of a very large ring spinning at a certain RPM. My initial thought is that as people moved around within the spacecraft or station, it could shift the center of mass, thereby causing some weird effects that would have to be somehow compensated for, though perhaps I'm mistaken in assuming this.
My question is whether or not the rotation of the said objects would be maintained, or if additional propellant would be required to periodically "re-boost" the rotation of a station or spacecraft in order to maintain the desired RPM?
Thanks!,
