October 4, 2012 — Developers are working on a system to remove space junk using a harpoon fired from a satellite to pull it out of its orbit. On Wednesday, Russia’s Mission Control Centre dropped an earlier plan to move the International Space Station into a different orbit to avoid possible collision with space debris. NASA estimates that more than 21,000 fragments of orbital debris larger than 10cm are stuck in earth’s orbit. Graphic shows proposed idea to harpoon space junk and drag it back to Earth.
