The CleanSpace One satellite is being designed to grab expired satellites from orbit, and bring them back to Earth

NASA currently monitors approximately 17,000 pieces of space junk that are orbiting the earth at extremely high speeds. These odds and ends consist of things like dead satellites, spent rocket stages and parts that have broken off of spacecraft. As the amount of junk increases, it becomes increasingly difficult for functioning satellites to avoid colliding with it. When collisions do occur, the satellite is often destroyed, with the resulting debris further adding to the problem. Scientists from Swiss research institute EPFL, however, have decided that enough is enough – they’re currently developing a small satellite known as CleanSpace One, which will be tasked with grappling expired satellites and pulling them back to Earth.
