UoSAT-4, also known as UO-15 and OSCAR-15, is a British satellite in Low Earth Orbit. It was built by a spin-off company of the University of Surrey, Surrey Satellite Technology (SSTL) and launched in January 1990 from French Guiana.[1]
UoSAT-4 was launched on the same rocket as its sister satellite, UoSAT-3.[2]
Mission
UoSAT-4 carried equipment to supplement UoSAT-3, but failed after two days in orbit.[2]
The satellite forms part of the growing amounts of orbital debris orbiting around the Earth. The payload will decay in the Earth's atmosphere some time in the future.
