Before a human crew goes to Mars' moon Phobos or to even lower mass asteroids, could a long stay at such an object be simulated gravitationally in the space station? I've heard that the ISS people don't like movements which disturb their microgravity experiments.
But (when they are finished with that :) ) could the ISS at least for a few months spin enough to simulate the tiny surface gravity of Phobos? 0.0057 m/² I think. Wouldn't it be interesting to learn how dust fall and how humans orient in such an environment? If stuff eventually sail downwards, and if people prefer to sleep horizontally, then maybe that says something about what such miniscule gravity does to us. And maybe it would be good even for the ISS to swing a bit.
