The increasing space debris has a great influence on space activity. It has already been an actual problem how to deal with the threat of space debris to spacecraft. Aiming at the problem of low-orbit large-scale useless target recovery, a new combined flexible capture and recovery scheme was proposed based on the concept of space-based recovery technology. A space net was projected to capture the abandoned target which was passively de-orbited through the inflatable dragincreasing method. Then IRDT was utilized in reentry, deceleration and return to the ground. A dynamic model was established, and simulation calculation analysis was carried out. The simulation results show that the scheme is technically feasible and can be used for the capture and recovery of future space targets.

Key words: space active debris removal, space-based recovery, space net capture, inflatable drag-increasing deorbit, inflatable reentry, space debris
