The attitude control problem for spacecraft, with gas jet, or momentum exchange actuators, and using the recent nonlinear geometric control theory is studied. Necessary and sufficient conditions for controllability of the system, in the case that the gas jet actuators yield one, two or three independent torques are given. In the case of momentum exchange devices controllability is studied with three independent actuators, and controllability is shown to be impossible with fewer devices. The former conditions with gas jet actuators are presented in three equivalent ways, and an equivalence established with an earlier condition by J. Baillieul. The local controllability problem is also studied in the case of gas jet actuators yielding two independent torques.
