This Space Junk Removal Experiment Will Harpoon & Net Debris in Orbit

The first experiment designed to demonstrate active space-debris removal in orbit has just reached the International Space Station aboard SpaceX's Dragon capsule. The RemoveDebris experiment, designed by a team led by the University of Surrey in the U.K. as part of a 15.2 million euro ($18.7 million), European Union (EU)-funded project, is about the size of a washing machine and weighs 100 kilograms (220 lbs.). It carries three types of technologies for space-debris capture and active deorbiting — a harpoon, a net and a drag sail. It will also test a lidar system for optical navigation that will help future chaser spacecraft better aim at their targets. "For this mission, we are actually ejecting our own little cubesats," Jason Forshaw, RemoveDebris project manager at the University of Surrey, said last year. "These little cubesats are maybe the size of a shoebox, very small. We eject them and capture them with the net."
