DARPA's Satellite Servicing - Repurposing - Concept

Innovators Sought for DARPA Satellite Servicing Program, DARPA

"More than $300 billion worth of satellites are estimated to be in the geosynchronous orbit (GEO--22,000 miles above the earth). Many of these satellites have been retired due to normal end of useful life, obsolescence or failure; yet many still have valuable components, such as antennas, that could last much longer than the life of the satellite. When satellites in GEO "retire," they are put into a GEO disposal or "graveyard" orbit. DARPA's Phoenix program seeks to develop technologies to cooperatively harvest and re-use valuable components from retired, nonworking satellites in GEO and demonstrate the ability to create new space systems at greatly reduced cost."
