The Stellenbosch UNiversity SATellite is 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. Sunsat was built by post-graduate engineering students at the University of Stellenbosch. Its AMSAT designation was SO-35 (Sunsat Oscar 35). Using only the above description and what you know about the world, "The Stellenbosch UNiversity SATellite is the first miniaturized satellite designed and manufactured in South Africa. the second satellite launch was not successful" is definitely correct, incorrect, or inconclusive?
