Phoenix
Abstract
To date, servicing operations have not been conducted on spacecraft beyond low earth orbit (LEO). A large number of national security and commercial space systems operate at Geosynchronous (GEO) altitudes, furthermore, many end-of-life or failed spacecraft drift without control through portions of the GEO belt, creating a growing hazard to operational spacecraft. Technologies for servicing of spacecraft with the expectation such servicing would involve a mix of highly autonomous and remotely (i.e., ground-based) teleoperated robotic systems have been previously pursued. The Phoenix servicing program will build upon these legacy technologies, tackling the more complex GEO environment and going beyond pure traditional servicing functions. The program seeks to repurpose high value long life components on existing satellites in GEO, in full collaboration and cooperation with existing satellite owners, utilizing commercial ride-along capability to send newly developed small, modular, and inexpensive "satlet" satellite modules into GEO for use in upgrading, fixing, repairing, and enhancing the repurposed components. Key challenges include transportation and orbital maneuvering, robotic systems and integration, and extravehicular tool requirements. The anticipated transition partner is the Air Force.
