A British satellite, designed to test out ways to clean up debris in space, just successfully ensnared a simulated piece of junk in orbit using a big net. On Sunday, September 16th, the vehicle, known as the RemoveDEBRIS satellite, deployed its onboard net, which then captured a nearby target probe that the vehicle had released a few seconds earlier. The demonstration shows that a simple idea like a net may be an effective way to clean up all the material orbiting Earth.

The RemoveDEBRIS satellite is meant to try out numerous different methods for cleaning up space junk, which has become a growing problem ever since we started launching rockets into orbit. Thousands of dead, uncontrollable objects linger in orbit, including defunct satellites, spent launch vehicles, and other pieces of debris that have come off other spacecraft. And all of this junk is moving fast, at upwards of 17,000 miles per hour. The more debris we have in orbit, the higher the chance that these pieces might collide at break-neck speeds, creating even more debris that could pose a threat to other spacecraft.
