The NASA Space Communications Testbed (SCT)

A robust and continuously available space communications network will play a key role in the planning and execution of safe and successful manned and robotic missions to the Moon, Mars and beyond. As future space missions become increasingly complex, it is essential that NASA develop a low cost method for validating, optimizing and verifying communications architectures, technologies and operational procedures for the evolving elements of the Space Exploration program. To this end, the Space Communications Testbed (SCT) is being developed by Comsat Laboratories, Glenn Research Center, Jet Propulsion Laboratory, Goddard Space Flight Center, and Langley Research Center. The SCT will be geographically distributed and seamlessly integrated between Comsat Laboratories and the various NASA Centers with each providing support in their relevant areas of expertise. The SCT will focus on the detailed testing of advanced space and ground communications networks, technologies and client applications essential for future exploration missions
