DARPA’s Plans To Reuse Satellites
DARPA Opens International Dialog on Satellite Servicing
“Current satellites are not designed to be serviced in space. When a communication satellite in geosynchronous orbit (GEO) fails 36,000 kilometers above the earth, typically, it is moved into a “graveyard” orbit where it remains indefinitely. Many of the satellites which are obsolete or have failed still have usable antennas, solar arrays and other components which are expected to last much longer than the life of the satellite, but currently there is no way to re-use them.”
