DARPA's Phoenix Would Harvest Dead Satellites:
NASA launches its TDRS-K tracking and data-relay satellite successfully on a Atlas V booster on Jan. 30. Then, on Feb. 1, launch of the Intelsat-27 commercial communications satellite on a Sea Launch booster fails.
TDRS-K cost NASA $350 million and its Atlas V launch another $200 million or so. Intelsat-27 and its launch would have cost less, but its failure still illustrates the high costs and risks in launching space hardware.
So DARPA is looking to dramatically reduce the cost, and risk, of launching communications satellites into geosynchronous orbit by instead removing and reusing antennas from retired spacecraft in graveyard orbit.
