Taking CD players into the International Space Station, Science Officer Don Pettit demonstrates gyroscopic spin stabilization in microgravity in the Saturday morning science. Floating a CD player in microgravity, Pettit shows us how the player spins irrationally, and when the CD inside is played how the spinning becomes more stable, a spinning CD provide enough stability to set the player quite stable. Pettit also combines two and three CD players perpendicularly, tied by tape to depict a gyroscopically stabilized platform, in the off position the CD players again act like solid bodies and spin irrationally, but when they are turned on they show a far better stability than a single CD player. This means a stable platform can be used as an utility device up in gravity.
