A servicing system for on-orbit spacecrafts is disclosed. The system comprises a servicing or host spacecraft configured to perform on-orbit servicing of client spacecrafts. The servicing spacecraft comprises a dedicated, deployable, boom having capture and docking mechanisms. The capture mechanism comprises a plurality of capture arms attached to a grounding structure. In one embodiment, the capture arms are kinematically linked and are free to rotate with respect to the grounding structure using a single actuator, thereby synchronizing the rotation of the arms for any angular displacement of the actuator, thus the arms form a circle that is concentric with the boom axis. In a second embodiment, there are two sets of capture arms, with the arms in each set kinematically linked and independently actuated; thus, the two sets cooperatively form different grasping geometries. Further, the docking mechanism is configured to enable the host spacecraft to dock with the client spacecraft. The servicing spacecraft may also be configured to carry a robotic arm and a suite of end-effectors that can be automatically changed out on-orbit. The suite of end-effectors may include one configured with the disclosed capture mechanism, and another may be configured with the disclosed docking mechanism.
