Soyuz Kontakt (Soyuz Contact) was the docking hardware of the Soviet crewed lunar spacecraft program. The Soviet lunar human program was canceled in 1974 after many failures. Four failures of the N-1 Rocket super heavy-lift launch vehicle and the success of the U.S. Apollo program ended the Soviet crewed moon program.[1]
