Apogee: 747 km (464 mi). Perigee: 395 km (245 mi). Inclination: 96.6000 deg. Period: 96.10 min. Delayed from April 15; October 18, 19, 26, 28; Nov. 4, 9 and 11; 2004, and March 2, 2005. Autonomous Rendezvous Technology mission, planned to guide itself to within a few metres of a US satellite. On April 16, DART closed within 100 m of the MUBLCOM satellite, then evidently began a series of out-of-control maneuvers resulting in an in-space collission and MUBLCOM being bumped into a 3 to 5 km higher orbit. Remarkably both satellites continued to function. DART then detected that it was running unexpectedly low on nitrogen cold gas used for orientation. Its autonomous software aborted further rendezvous operations and the DART was deorbited shortly thereafter.

The Microsatellite Technology Experiment was a classified mission, believed to be a test of prototype inspect-and-disable satellites that would control the constellation of geostationary satellites on which the world depends for television reception and communications. Each microsatellite, one built by Orbital Sciences, and the other by Lockheed Martin, had a mass of about 250 kg. They were believed to be solar-powered and equipped with propulsion systems that would allow them to rendezvous with geosynchronous satellites. Once they had reached the satellite, they would presumably be capable of destroying, disabling, or jamming them. To deliver the two satellites to near-synchronous orbit, a Naval Research Laboratory liquid propellant bus equipped with a 400 N main engine and solar panels was used.
