Space, the final frontier is in dyer need of cleaning; according to NASA, “the Earth’s orbit has been made a mess by space junk.” With that said it needs to be cleaned up. Apparently they had a handle on things, but NASA further explains that: “two events in the past four years — a 2007 Chinese anti-satellite weapon test and a 2009 crash-in-orbit of two satellites — put so much new junk in space that everything changed.”

The Defense Advanced Research Projects Agency  called “Catcher’s Mitt” has mentioned, ” harpoons, nets, tethers, magnets and even a giant dish or umbrella-shaped device, that would sweep up tiny pieces of debris,” and the  ”think-tank” which is also an arm of the Defense Department has outlined all sorts of unusual techniques.”

Donald Kessner, who headed the National Academy of Sciences says; he likes one company’s idea of a satellite that is armed with nets that could be sprung on wayward junk. Attached to the net is an electromagnetic tether that could either pull the junk down to a point where it would burn up harmlessly or boost it to safer orbit.
