Salyut 4 ( Russian Салют-4 "Salut") was a Soviet space station that was launched on December 26, 1974 by a Proton-K rocket into orbit. It burned up on February 2, 1977 when it re- entered the earth's atmosphere. During its operating time, it was manned by two crews: first by Alexei Gubarew and Georgi Grechko with the spaceship Soyuz 17 , then by Pyotr Klimuk and Vitaly Sevastyanov with Soyuz 18 . Another visit took place with the unmanned spacecraft Soyuz 20 .
