They all travel at speeds up to 17,500 mph (miles per hour), fast enough for a relatively small piece of orbiting debris to damage a satellite or a spacecraft.2 The rising population of space debris increases the potential danger to all space vehicles, but especially to the International Space Station, space shuttles and other spacecrafts with humans on board.
