Challenge-1[1] or Challenge One (TelNet Challenge One)[2][3] is the first domestically made satellite from Tunisia. It was launched on 22 March 2021 by Russia on a Soyuz 2 rocket from Baikonur in Kazakhstan. The satellite was built by a team of telecommunications engineers from TelNet, as an Internet of Things satellite.[1][3] This marked Tunisia as the 6th African country[1] and the 1st country in the Maghreb to manufacture its own satellite.[4] The satellite is to be the first of a constellation of 30 satellites.[5] The satellite was first announced in September 2019 for a July 2020 launch.[6]
