NASA's bouncing 'Hedgehog' robot is designed to explore comets

Eventually its batteries ran down we lost contact. A sad way to end the mission, but we can't say that we didn't learn anything: NASA engineers are now working on a low-gravity unmanned exploration vehicle designed to bounce, tumble and roll around asteroids and comets. It's called the Hedgehog.
