ABSTRACT:
A multipurpose modular spacecraft is adaptable quickly and easily for performing a variety of short- and long-range space missions, such as on-orbit maintenance missions and the like. The multipurpose modular spacecraft comprises a fully integrated short-range space vehicle including one or more relatively small modular propulsion sets which provide propulsion capability for relatively short-range missions and close-in maneuvering requirements. Longer-range propulsion capability is provided by a comparatively larger propulsion module designed for removable nested mounting within an open-sided chamber in the short-range vehicle. Relatively simple and easily operated latch mechanisms retain the propulsion sets and the propulsion module on the short-range space vehicle in preselected positions with relatively simple electrical fittings connected together to provide a control interface with the short-range space vehicle. The propulsion sets and/or the propulsion module can be replaced or removed as required to refuel the modular spacecraft or to adapt the spacecraft for a particular space mission.
