Crew: Dzhanibekov, Makarov. First docking to a space station of two manned spacecraft at one time. First station 'lifeboat' swap. First crew to visit another already aboard a space station. Backup crew: Ivanchenkov, Kovalyonok.

First crew to visit another already aboard a space station.

Narrative (adapted from D S F Portree's Mir Hardware Heritage, NASA RP-1357, 1995)

Soyuz 27 docked without incident at the front port of Salyut 6 carrying cosmonauts Oleg Makarov and Vladimir Dzhanibekov, who formed the first Visiting Expedition crew in the Soviet space station program (or, for that matter, in any space station program). For the docking, the Tamyrs withdrew to their Soyuz 26 spacecraft and sealed the hatch into Salyut 6 behind them. This was done in the event of a depressurisation emergency associated with the docking of Soyuz 27. There was also some concern that stresses and vibrations produced when the 7-ton Soyuz 27 spacecraft contacted the front port might transmit through Salyut 6, forcibly uncoupling Soyuz 26 from the rear port. The Soyuz 27-Salyut 6-Soyuz 26 combination massed about 33,000 kg and featured seven compartments: two descent modules, two orbital modules, the transfer compartment, the work compartment, and the small aft intermediate compartment. The four cosmonauts conducted many experiments, including Rezonans, which was designed to determine if resonant frequencies might threaten the structural integrity of the three-spacecraft combination. The experiment called for the cosmonauts to jump around Salyut 6 on command from the TsUP. The guest crew spent 5 days on Salyut 6, then returned to Earth in Soyuz 26, leaving the fresh Soyuz 27 spacecraft for the Tamyrs. This was the first of many such spacecraft swaps.
