A reusable space vehicle docked in an intermediate orbit for rescue missions allows a satellite to be serviced with less delay, energy expenditure, and cost than a space vehicle launched from Earth for each mission. The reusable repair vehicle can be moved from one orbit to another with minimal energy expense while not having to wait for a launch window. Once a servicing need is identified, a destination orbit is identified for the space vehicle and a minimum energy path is identified. If the time to the next launch window between the docking orbit and the destination orbit happens to be near enough to allow for a timely rendezvous, the space vehicle is moved directly to the destination orbit. The space vehicle can be a vehicle designed to be piloted by humans or telerobotically. In one implementation, the inactive space vehicle is docked in an Intermediate LEO orbit (altitudes of approximately 250 km to approximately 500 km) and is used to rendezvous with objects in High LEO orbits (altitudes of approximately 500 km to approximately 1500 km) or objects in Low LEO orbits (altitudes of approximately 250 km or less). The space vehicle can be a modified lunar lander.
