Just as we are talking about space junk, which come to find out there is over 9000 tons up there. A rocket has launched carrying an Earth imager that was developed in South Korea. The demonstration mission consists of two spacecraft, a servicer, and a client. The servicer will use sensors to find the client. Basically like a game of cat and mouse. The servicer will chase down the client and try to latch onto it. The mission is to simulate how we could rendezvous with, dock, and capture pieces of free-floating space junk. The junk would be lowered to where it re-enters Earth's atmosphere. Pretty neat, I hope it works out.
