Phoenix
Abstract
To date, servicing operations have never been conducted on spacecraft beyond low earth orbit (LEO). A large number of national security and commercial space systems operate at geosynchronous earth orbit (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 that such servicing would involve a mix of highly autonomous and remotely (i.e., ground-based) tele-operated robotic systems have been previously pursued. The Phoenix servicing program will build upon these legacy technologies, tackling the more complex GEO environment and expanding beyond pure traditional servicing functions. The program seeks to validate robotics operations in GEO suitable for a variety of potential servicing tasks, in full collaboration and cooperation with existing satellite owners. The program will examine utilization of a new commercial ride-along capability to GEO called Payload Orbital Delivery (POD) to support hardware delivery for upgrading, repairing, assembling, and reconfiguring satellites. The program will include an early LEO flight experiment focused on satlets as a path of risk reduction for modular assembly on orbit. Key challenges include robotic tool/end effector requirements, efficient orbital maneuvering of a servicing vehicle, robotic arm systems, and integration and efficient and low cost transportation of robotic tools. The anticipated transition partners are the Air Force and the commercial spacecraft servicing providers. Beginning in FY 2015, the GEO robotics portion of this effort will be funded under the Robotic Servicing of Geostationary Satellites program within this Project.
