Salyut 6 Visiting Expeditions | |
Soyuz 6 EP-1 was a 1978 Soviet crewed space flight to the orbiting Salyut 6 space station, during the expedition EO-1. It was the third crewed flight to the station, and the second successful docking. It was also the first crew to visit an occupied station and marked the first time that three spacecraft were docked together. The launching spacecraft was Soyuz 27 (Russian: Союз 27, Union 27), and the crew of EP-1 are often referred to as the Soyuz 27 crew.
The main function of the mission was to swap Soyuz craft with the orbiting crew, in so doing freeing a docking port for a forthcoming supply tanker. Cosmonauts Vladimir Dzhanibekov and Oleg Makarov returned to Earth in the Soyuz 26 spacecraft after spending five days on the station.
