How Did Georgiy Grechko Die?

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.
