Abstract: PROBLEM TO BE SOLVED: To provide an attitude control method for an orbital non-cooperative object capable of damping the angular momentum of the orbital non-cooperative object by simple method without a large-scale system such as a net, tether or the like. SOLUTION: A projection material 2 is projected to the non-cooperative objet 1 freely moving on aerospace orbit from another satellite to apply an impact in the direction of damping the angular momentum, thereby reducing the angular momentum. Accordingly, the movement of the non-cooperative object can be made into a single spin or stopped so that capture by a robot arm or the like is enabled.

Abstract: PROBLEM TO BE SOLVED: To provide a joint mechanism appropriate for a rotary joint to be used for a joint mechanism of a robot to be used in space, and to provide a rotary joint. SOLUTION: In this joint mechanism for transmitting the force from a primary side to a secondary side, an elastic body and a preload generating means for giving a selected preload to the elastic body are arranged between a primary side member and a secondary side member. The elastic body is energized by the preload selected by the preload generating means so that a phase difference between them becomes zero. When the force more than the selected preload is applied between both the members, this variable holding force joint is characterized to generate a phase difference between them.
