Soyuz 32

Soyuz 32 (Russian: Союз 32, Union 32) was a 1979 Soviet manned space flight to the Salyut 6 space station. It was the eighth mission to and seventh successful docking at the orbiting facility. The Soyuz 32 crew was the third long-duration crew to man the space station.

Cosmonauts Vladimir Lyakhov and Valery Ryumin spent 175 days in space, setting a new space endurance record. Because of the failure of a visiting crew to successfully dock and the resultant decision to send an unmanned Soyuz craft as a replacement return vehicle, the Soyuz 32 crew had no visitors.
