One of the promising capture methods currently being studied by ESA is the use of nets to capture non-cooperative space debris.
This technology is also being explored for use in other domains. Recently experts from Michigan Technological University’s HIRoLab developed a “drone-catcher” that has the capability to capture unmanned aerial vehicles (UAVs) by shooting out a net:
Nets appear to have a very large applicability to debris, because of the associated scalability and low sensitivity to the target attitude. A thorough programme for characterisation, development and testing of throw-net systems is being implemented by ESA.
SKA Polska is one of the companies working with ESA on the development of the net for capturing space debris. They have conducted 0 g testing during parabolic flights, watch this in the video below:
