That's all fine, ambitious, and so on - but once you're at the asteroid you need to be able to get around it. Now this asteroid is planned to be small, maybe not a lot bigger than the Orion spaceship visiting it, so it won't have any gravity worth speaking of. Loosing your grip and floating pathetically away from the asteroid would be kind of embarrassing, so Draper engineer Michele Carpenter, Draper fellow Todd Sheerin, and some  MIT students have been working on 'control moment gyroscope (CMG) hardware' - essentially the beginnings of a gyroscope controlled jetpack.Michele Carpenter, told Popular Science that “The CMGs enable a finer level of control by operating continuously. Thrusters aren’t well suited for this function because they are discrete ...
