(Crewed missions)

Soyuz 27 (Russian:Союз 27,Union 27) was a 1978Soviet crewed spacecraft which flew to the orbitingSalyut 6 space station, during the missionEP-1.[2] It was the third crewed flight to the station, the second successful docking and the first visitation mission. Once docked, it marked the first time that three spacecraft were docked together.

The main function of the EP-1 mission was to swap Soyuz craft with the orbiting crew, in so doing freeing a docking port for a forthcoming supply tanker.CosmonautsVladimir Dzhanibekov andOleg Makarov returned to Earth in theSoyuz 26 spacecraft after spending five days on the station. The descent module is displayed at theSergei Pavlovich Korolyov Museum of Cosmonautics inZhytomyr,Ukraine.[3]
