Space Junk Net Successfully Completes Capture Test

A British satellite has just successfully proven that it can capture space junk using a system both innovative and old-school: nets.

RemoveDebris, based out of the University of Surrey and funded by a variety of partners including the European Commission and Airbus, has had the goal of finding a low-cost space junk removal system for years. Back in June, the RemoveDEBRIS system was deployed from the International Space Station. On September 16th, the group began to proceed with in-space testing.

Operating over 186 miles (30o km) above the Earth, the RemoveDEBRIS system set out to capture a tiny satellite known as a CubeSat. With a net shooting off at around 44 MPH (20 meters per second) and a vision based navigation including cameras and LiDAR, the net was able to quickly capture the runaway CubeSat.

About RemoveDebris mission:

RemoveDebris is an EU (European Union) research project to develop and fly a low-cost in-orbit demonstrator mission that aims to de-risk and verify technologies needed for future ADR (Active Debris Removal) missions.

RemoveDebris is aimed at performing key ADR technology demonstrations (e.g., capture, deorbiting) representative of an operational scenario during a low-cost mission using novel key technologies for ADR. The project is based on and aimed at contributing to global/European ADR roadmaps.

A microsatellite called here RemoveSAT, will release, capture and deorbit two space debris targets, called DebrisSats, in sequence using various rendezvous, capture and deorbiting technologies thus demonstrating in orbit, key ADR technologies for future missions in what promises to be the first ADR technology mission internationally.

Space junk is an ever-growing problem with more than 7,500 tonnes of redundant hardware now thought to be circling the Earth. Ranging from old rocket bodies and defunct spacecraft through to screws and even flecks of paint – this material poses a collision hazard to operational missions.

The rising population of space debris increases the potential danger to all space vehicles, but especially to the International Space Station (ISS), space shuttles, satellites, and other spacecraft.
