A spacecraft structure using functionally independent modules assembled around a lightweight core structure to provide a vehicle that is lighter, uses less volume, and is easier to design, manufacture and test than a conventional spacecraft. In the disclosed embodiments, the modules are formed on generally flat panels, which serve as thermal radiators. The modules extend radially from the core structure and are attached to the core structure either in coplanar rows that extend axially along the core structure or in a coplanar set that extends circumferentially around the core structure. Interconnection between modules is achieved through a backbone interface, through which the modules are connected to the core structure. A large number of variant configurations may be implemented using the modular approach, by selecting a core, components and modules of number and size to meet mission requirements. The modular spacecraft may be easily designed and adapted to operate with its radiating modules facing in north-south directions for maximum thermal radiation, or in other orientations as needed for specific missions. All of the configurations have the advantage that they occupy a relatively small volume and allow large components, such as antennas and solar arrays, to be stowed for launch in the ample spaces between rows of modules.

[ What is claimed is:] [1.] A modular spacecraft architecture, comprising:a lightweight core structure selected to accommodate system components needed for a spacecraft mission and a propulsion system needed for the mission;a plurality of functionally independent, low-volume, cooperative spacecraft modules that remain attached to the core structure during the spacecraft mission and cooperate with each other for purposes of the spacecraft mission, each spacecraft module providing for its own structural integrity and its own thermal management; anda standardized backbone interface for interconnecting the spacecraft modules to allow for the transfer of power, data and other signals through the interface and thence to others of the modules;whereby the low-volume spacecraft modules are light in weight and leave space for stowing large components between modules in a launch configuration.
