Since the number of space-debris (hereinafter, referred to as “debris”) in earth orbit is increasing year after year. High risk of collision that debris and operational satellites. Peculiarly, the density of low orbits is high. Debris fall into atmosphere and disappears naturally. However it requires a lot of time. Orbits of altitude of 800 or higher, it'll be necessary for hundreds of years. Each research institution reported even when new satellites aren't launched, the number of debris automatically increases due to collision and crushing of each debris (Kessler syndrome state). If the number of debris continue to increase, it is evident that will a serious impact on future space development. Therefore, it is urgent to actively remove debris from onorbit. The removal method of dropping debris to the Earth, in the same as natural extinction is promising. As above, require deceleration to drop debris. However, propulsion system of the debris is not working. For this reason, mounting propulsion device is necessary. In this study, we assume that the upper of the H-series rocket will be the removing target and capturing it using robot arm. In this paper, results of examining capture strategy and a trial product of gripping mechanism.
