The Stellenbosch UNiversity SATellite or SUNSAT (COSPAR 1999-008C) was the first miniaturized satellite designed and manufactured in South Africa. It was launched aboard a Delta II rocket from the Vandenberg Air Force Base on 23 February 1999 to become the first launched South African satellite. Sunsat was built by post-graduate engineering students at the University of Stellenbosch. Its AMSAT designation was SO-35 (Sunsat Oscar 35).
Last contact by ground control with SUNSAT was on 19 January 2001 and on 1 February 2001 the end of SUNSAT's functional life in orbit was announced. The satellite operated in orbit for nearly 2 years.
It is predicted to reenter the atmosphere after about 30 years from launch.
