1971-032A
The first DOS station, DOS 1, was originally to be named Zarya, but was renamed Salyut after launch on 1971 Apr 19. It had the designation 17K No. 121.
The first crew reached the station on Apr 24; Soyuz-10 soft docked but could not complete the seal and had to undock and return to Earth without boarding the station.
A second crew docked on Jun 7 aboard Soyuz-11. Georgiy Dobrovolskiy, Viktor Patsaev, and Vladislav Volkov became the first space station crew, and settled into a routine of on-board experiments. After shattering the spaceflight duration record they prepared to return to Earth. The crew transferred back to Soyuz-11, closed the Salyut hatch, and undocked from the station completing the first station expedition.
Salyut was maintained in orbit for several months, but was deorbited over the Pacific in October when it became clear that the Soyuz program would remain grounded for some time. This set the precedent for the controlled reentry of massive spacecraft in empty areas of the South Pacific Ocean.
Soyuz-10 was docked to Salyut for 5h30m. Soyuz-11 was docked for 22d10h40m and the hatch open/close time was about 22d08h35m.
