> You can turn a satellite by spinning up a flywheel and then reabsorbing the angular momentum when you reach the desired orientation.

Wouldn't 2 of those allow for 2 different centers of rotation. If so, we can just walk though space.

No, the center of rotation is always that of the full system. It's not relative to which flywheel happens to be spinning.
