Earth has a space junk problem. More than half a million pieces of debris float in orbit around our planet, any of which could collide with a satellite or spacecraft and cause real damage. Unfortunately, we don't have a reliable way to capture the junk and move it to a more distant orbit where it won't cause harm. Now, Stanford and NASA researchers have developed a robotic device to do just that, inspired by the sticky feet of the gecko.
