Tethers Unlimited, Inc (TUI) wants to capture asteroids and space debris while minimizing risk to the primary spacecraft. TUI proposes the use of a nanosatellite-scale satellite, called the Weightless Rendezvous And Net Grapple to Limit Excess Rotation (WRANGLER) System, which will capture and de-spin the space object. WRANGLER will do that by combining two innovative technologies that have been developed by TUI: the GRASP deployable net capture device, and the SpinCASTER tether deployer/winch mechanism. The leverage offered by using a tether to extract angular momentum from a rotating space object enables a very small nanosatellite system to de-spin a very massive asteroid or large spacecraft.
