Dealing with space junk.

Space junk is a growing problem — 200,000 pieces and counting — and as the amount of earth’s orbital debris increases, so does the chance some satellite will be involved in a cosmic collision. As this would cause much gnashing of teeth and woe for the affected terrestrial parties, some researchers from NASA’s Ames Research Center have pitched the idea of removing said junk with a laser — once again proving that everything’s better with lasers…

The idea is to use a 5kW ray, like the one we’ve got at the Starfire Optical Range, to slow our galactic garbage enough to burn it up in earth’s atmosphere. Current estimates say such a laser could eliminate ten pieces of junk a day, promising us a future of neat and tidy skies.
