RemoveDEBRIS is a satellite that is supposed to test various technologies in space in order to remove space debris . The experimental satellite platform was brought to the ISS on April 4, 2018 with the SpaceX CRS-14 mission and placed in orbit on June 20, 2018. The mission is under the direction of the University of Surrey .
consortium
RemoveDEBRIS was planned and manufactured by an international consortium. These include:
- Surrey Space Center / University of Surrey United Kingdom : coordination, subsatellites, sails
-
ArianeGroup , formerly Airbus Safran Launchers ( France ): satellite control
-
Surrey Satellite Technology ( United Kingdom ): Platform and Avionics
-
Airbus ( United Kingdom ): Harpoon
-
Airbus ( Germany ): network
-
Airbus ( France ): Visual identification
-
Center Suisse d'Electronique et de Microtechnique ( Switzerland ): Visual identification
-
Institut national de recherche en informatique et en automatique ( France ): Visual identification
-
Innovative Solutions In Space ( Netherlands ): Mechanism for deploying the subsatellites
-
Stellenbosch University ( South Africa ): Subsatellites
mission
RemoveDEBRIS will test different methods of how space debris can be removed effectively. For this purpose, the satellite will expose its own subsatellites as targets.
network
In September 2018 RemoveDEBRIS deployed a sub-satellite called DebrisSAT-1 (DS-1) . With a balloon, its frontal area was greatly enlarged, so that the braking effect of the residual atmosphere had a stronger effect and it moved away from RemoveDEBRIS. RemoveDEBRIS recaptured DS-1 with a network.
Visual identification
Another subsatellite, DebrisSAT-2 (DS-2) was used as a target for the second experiment on October 28, 2018. RemoveDEBRIS used a 2D camera and a 3D lidar device to observe DS-2 and determine its position and speed.
Harpoon
A third experiment was carried out on February 8, 2019. A harpoon was shot at a target that was located at the end of a boom 1.5 meters in length.
sail
The last experiment was planned for March 2019. It should explore the possibility of accelerating re-entry with the help of an inflatable sail . Without this sail, RemoveDEBRIS would remain in orbit for over 2.5 years after the end of the experiments. The orbit height should be reduced by the sail so quickly that the satellite burns up after 8 weeks. In fact, it was still in orbit at an altitude of 398–403 km in mid-2019.
