ABSTRACT:
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.
