At 17:59 UTC on March 1, 1984, the second satellite designed and built by the University of Surrey's Spacecraft Engineering Research Group - UoSAT in the United Kingdom, UoSAT-2 (UO-11) was launched on a Delta rocket from the Western Test Range at Vandenberg Air Force Base, Lompoc, California with LANDSAT 5. It weighs 60 kg.

Among its many experiments, UoSAT-2 carried the Digital Communications Experiment, which was one of the first (if not the first) non-military use of store-and-forward techniques with Low Earth Orbiting Satellites. UoSAT-2 was the test-bed for the packet radio satellites as we know them today. (Thanks WD3Q)
