Even though our shuttles are no longer heading to space, there is still a ton of junk up there, and Swiss engineers would like to clean it up. NASA says more than half a million pieces of debris are circling the planet, including old satellites. Swiss engineers are developing a small satellite called CleanSpace One to do the job. It would grab space junk and pull it back towards earth, where both would burn up during re-entry.
