Spacecraft servicing devices and related assemblies, systems, and methods

A spacecraft servicing system, comprising:

• a host ship;
• a resupply spacecraft;
• and
• mission extension pods each comprising at least one spacecraft servicing component and a docking mechanism, the mission extension pods collectively carried by the host ship, the host ship configured to transfer a mission extension pod of the mission extension pods to a location external to a target spacecraft where the docking mechanism of the mission extension pod engages with the target spacecraft in order to service the target spacecraft with the at least one spacecraft servicing component of the mission extension pod, the docking mechanism of the mission extension pod securing the mission extension pod to the target spacecraft, the host ship configured to retrieve at least some of the mission extension pods supplied from the resupply spacecraft at a selected orbit in space and to retain the at least some of the mission extension pods on an external portion of the host ship,
• wherein the host ship comprises a pod retrieval mechanism, the pod retrieval mechanism configured to engage and secure at least one mission extension pod of the mission extension pods in space for transport and to deploy the at least one mission extension pod at the target spacecraft, and
• wherein the pod retrieval mechanism comprises a robotic arm coupled to the host ship.
