USA 52 was launched from Cape Canaveral, Florida, on the same Delta rocket used to launch USA 51. The Relay Mirror Experiment (RME) satellite hosted a 24-inch mirror to test pointing technology by deflecting ground-based beams back to earth. Results from experiments aboard this satellite will aid in the design of laser defenses against missile threats. RME was built by Ball Space Systems Division and weighed 1,040 kg at launch.
