Access for servicing, from the Space Station to satellites flying at similar or different orbital altitudes; limitations in accessibility due to differential nodal regression between the orbits in question; avoidance of high delta-V expenditures for plane change maneuvers; and the orbit transfer alternatives of retrieving a satellite from higher orbit for servicing at the station or shuttle versus in situ servicing at the satellite orbit altitude by using an orbital maneuvering vehicle carrying a telerobotic servicer and the necessary replacement parts are discussed. Scenarios that promise large cost savings through reduced propellant-to-orbit transportation charges as well as other mission operation expenditures are considered. Natural orbit evolution factors often can be exploited to provide these benefits. The cumulative savings are projected to amount to tens of millions of dollars per year.
