Sigma 5 was the fifth international manned spaceflight mission of the Sigma program between the Mascyllary and Dulebian space programmes. It was the first mission that successfully landed humans on the Moon. The overarching project, and its culmination into the first lunar landing, evolved into a keen symbol of détente between the democratic and communist blocs of the Great Game and is agreed upon to mark the end of the Space Race.
The four crew members and astronauts Lukas Brennzer, Georgy Cheryomushev, Walther Gählen and Aleksandr Sahalinov launched from X on May 2, 1980 at 12:10:00 UTC with a Atlant-3 rocket, before arrving in lunar orbit three days later. While Command Module pilot Cheryomushev remained in orbit and flew the X alone, Brennzer, Gählen and Sahalinov jettisoned the Lunar Module Einigung to depart for landing on the Moon; at 13:07 UTC on May 5, 1980, Einigung touched down in the Mare Ingensis region. Five hours later, Sahalinov became the first person to step onto the lunar surface, with Brennzer and Gählen following twenty and fifty-three minutes respectively.
