Read the following paragraph and determine if the hypothesis is true:

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).

Hypothesis: post-graduate engineering students at the University of Stellenbosch designed another satellite after that
It's impossible to say
