About Georgy Grechko
Georgy Mikhaylovich Grechko was a Soviet cosmonaut. He flew to space on three missions, each bound for rendezvous with a different Salyut space station. Soyuz 17 was the first crewed vehicle to visit Salyut 4, Soyuz 26 was the first crewed vehicle to visit Salyut 6, and Soyuz T-14 visited Salyut 7. During the latter mission, Grechko helped to relieve the crew of Soyuz T-13, who had repaired damage to the station. Georgy Grechko's first mission to space began during the winter of 1974, when he and fellow Soviet cosmonaut Aleksei Gubarev were crewmen of the Soyuz 17-Salyut 4 mission. Grechko made the first spacewalk in an Orlan space suit on 20 December 1977 during the Salyut 6 EO-1 mission. A minor planet 3148 Grechko discovered by Soviet astronomer Nikolai Stepanovich Chernykh in 1979 is named after him.
