Orbital Sciences awarded contract for DARPA satellite program

Effort will develop new a space architecture in which traditional large, multi-functional "monolithic" spacecraft are replaced by clusters of wirelessly interconnected spacecraft modules.

Orbital Sciences Corp. (Dulles, Va., USA) announced on Dec. 18 that it has been awarded a Phase 2 contract by the Defense Advanced Research Projects Agency (DARPA, Arlington, Va.) to develop the final design for System F6 (Future Fast, Flexible, Fractionated, Free-Flying Spacecraft). The Phase 2 award to Orbital came as a result of a down-select by DARPA from among several companies that participated in the program's Phase 1 study contracts in 2008 and 2009. The Phase 2 contract is valued at $74.6 million over a one-year period of
performance.

The objective of the System F6 program is to develop and demonstrate the basic building blocks of a radically new space architecture in which traditional large, multi-functional "monolithic" spacecraft are replaced by clusters of wirelessly interconnected spacecraft modules. Each of these modules performs a subset of the tasks performed by a large classical spacecraft and works together in a cluster to provide the same overall effective mission capability. By allowing the various functions of a spacecraft to be developed and launched separately, this type of "fractionated" system provides benefits such as reduced overall risk, budgetary and planning flexibility, faster initial deployment, and ultimately greater survivability, including selective replacement of damaged or obsolete elements of a complex spacecraft.

"System F6 has the potential to be a game-changing innovation in the way space systems are designed, built and operated in much the same way as the DARPA-developed Internet has changed many aspects of our daily lives," stated Gregg Burgess, Orbital's vice president for National Security Systems in the company's Advanced Programs Group. "System F6 is not just an incremental improvement in technology, but rather a fundamental transformation of the entire space community. Fractionated and networked architectures could be the answer to recurring problems that debilitate the space sector, including significant cost increases, late deliveries, launch mishaps and on-orbit failures."

In the next phase of the System F6 program, Orbital will be responsible for the detailed design and ground testing of the new technologies, architectures and programmatic concepts required to successfully fractionate a space system. These include wireless data communications, cluster flight operations, distributed spacecraft computing systems, rapidly relocatable ground systems, and value-centric design methodologies.

Orbital was selected by DARPA out of four Phase 1 contractors to continue work on Phase 2 of the program, leading to a planned flight demonstration in 2013. The company's program partners include IBM and NASA's Jet Propulsion Laboratory. Phase 2 will include development of the detailed design of the spacecraft modules, ground elements and launch options.
