Soyuz 17 (Russian: Союз 17, Union 17) was the first of two long-duration missions to the Soviet Union's Salyut 4 space station in 1975. The flight by cosmonauts Aleksei Gubarev and Georgy Grechko set a Soviet mission-duration record of 29 days, surpassing the 23-day record set by the ill-fated Soyuz 11 crew aboard Salyut 1 in 1971.
