Salyut 5 |

**Salyut 5**Program: Almaz.*Payload*: Almaz s/n 103-01.*Mass*: 19,000 kg. Class: Manned.*Type*: Space station. Spacecraft: Almaz .*Perigee*: 215 km.*Apogee*: 232 km.*Inclination*: 51.6 deg.*Period*: 88.9 min.*COSPAR*: 1976-057A.*Duration*: 411.24 days.Second successful flight of the Almaz manned military space station. Operated for 409 days, during which the crews of Soyuz 22 and 24 visited the station. Soyuz 23 was to have docked but its long-distance rendezvous system failed. Soyuz 25 was planned, but the mission would have been incomplete due to low orientation fuel on Salyut 5, so it was cancelled. The film capsule was ejected 22 February 1977 (and sold at Sotheby's, New York, on December 11, 1993!). The station was deorbited on 8 August 1977. In addition to the human crew two Russian tortoises (Testudo horsfieldi) and Zebrafish (Danio rerio) were flown.

The results of the Salyut 3 and 5 flights showed that manned reconnaissance was not worth the expense. There was minimal time to operate the equipment after the crew took the necessary time for maintenance of station housekeeping and environmental control systems. The experiments themselves showed good results and especially the value of reconnaissance of the same location in many different spectral bands and parts of the electromagnetic spectrum.
