Depends on the rotational speed of the shuttle. I guess that in order to
get the most out of the microgravity environment, the shuttle's
rotational speed will normally be trimmed to zero - which means a
motorized mount isn't even necessary (after all a motorized mount's
purpose is to cancel out the eart's rotation).
