On her part, Barnawi expressed her excitement and pride in announcing the launch date of the expedition to complete the goals of the Kingdom's space program, which will contribute to achieving future explorations in various fields. For his part, Al-Qarni said: "The fact is that our mission as the first Saudi astronauts to visit the International Space Station would not have been possible without the support of our wise leadership."
