1977-097A
DOS 5 (17K No. 125) was the first of the advanced DOS stations with two docking ports. It was launched on 1977 Sep 29 by a three stage Proton-K, and named Salyut-6.
The first visit to DOS 5 was a failure when Soyuz-25 could not dock with the -X (forward) port. Soyuz-26 docked at the rear, +X, port with the first crew, Romanenko and Grechko. Grechko made a spacewalk on Dec 19 to verify that the -X port was undamaged. Romanenko floated out the hatch briefly during this spacewalk, which was the first Soviet EVA since 1969.
In January 1978 the first visiting crew of Dzhanibekov and Makarov docked with the -X port in Soyuz-27 and brought Soyuz-26 back to Earth, leaving the long stay crew with a fresh transport ship and freeing up the +X port for the docking of Progress-1, the first automated cargo supply ship, the following week. A second visiting crew in March on Soyuz-28 featured the first 'guest cosmonaut', Vladimir Remek of Czechoslovakia. This visit didn't involve a ship exchange; Romanenko and Grechko returned to Earth in Soyuz-27 shortly after the Soyuz-28 crew landed. Their record setting mission demonstrated key space station operations of resupply and crew exchange, laying the groundwork for the DOS 8 (Mir) permanent occupations.
The station remained unoccupied until June when the EO-2 crew reached it aboard Soyuz-29. A Polish guest cosmonaut made an 8-day visit on Soyuz-30 two weeks later, accompanied by Russian commander Pyotr Klimuk. The aft port was vacant for only 4 days before being occupied by a second Progress cargo ship. Engineer Ivanchenkov made a spacewalk on Jul 29 to expose and retrieve experiment samples, with Commander Kovalyonok supporting from the open hatch. Progress-3 then brought more supplies in early August, followed by a new visiting crew aboard Soyuz-31. East German astronaut Sigmund Jahn and Russian commander Valeriy Bykovskiy carried out experiments and returned to Earth aboard Soyuz-29 on Sep 3, leaving their fresh ship at the rear port. On Sep 7 the EO-2 crew demonstrated a new manuever, undocking from Salyut aboard Soyuz 31 and backing off while controllers flipped Salyut end-to-end; they reapproached and docked with the front port. The rear port had to be kept free for Progress craft, since refuelling could only be done from that end. The flight took 29 minutes. After one more Progress resupply flight, the EO-2 crew landed in Soyuz-31 on Nov 2.
In Feb 1979 the EO-3 crew of Lyakhov and Ryumin docked at the front port in Soyuz-32 followed in March by Progress-5 at the rear port. On 1979 Mar 16 the ODU engine cover failed to open before an engine burn, and the cover was burnt through. Attempts to repair the ODU over the following week were unsuccessful. After undocking of the Progress, Soyuz-33 was launched with a Bulgarian astronaut aboard and Nikolai Rukavishnikov as commander, the first civilian to command a Soviet mission. However, an engine problem caused Soyuz-33 to miss its rendezvous, leaving the EO-3 crew with a transport ship nearing its sell-by date. After the Progress-6 resupply mission in May, Soyuz-34 was launched with no crew aboard and made an automatic docking on Jun 8. The aging Soyuz-32 was then recovered empty on Jun 13, and on Jun 14 the EO-3 crew flew Soyuz-34 round to the front port, later landing it safely on Aug 19. Progress-7 in July delivered the KRT-10 radio astronomy experiment which was left mounted in the rear port when the Progress undocked. However attempts to jettison it failed when it caught on the aft structure, and Ryumin made a spacewalk on Aug 15 to free it.
In Dec 1979 the automated Soyuz T spaceship made a test flight in which it docked to Salyut-6 and remained attached until Mar 1980 when it returned to Earth.
Later in Mar 1980 Progress-8 docked to the empty station in preparation for a new expedition. This was the first time a Progress had been sent while a crew was not aboard. On 1980 Apr 10 Soyuz-35 docked bringing with it the EO-4 crew of Leonid Popov and (once again) Valeriy Ryumin. Progress-9 brought more supplies at the end of April, and Soyuz-36 visited in May with civilian commander Valeriy Kubasov and Hungarian astronaut Bertalan Farkas, who exchanged ships and returned in Soyuz-35. Soyuz T-2, the first crewed test flight of the Soyuz T, docked in June for a brief visit. Progress-10 in July was followed by Soyuz-37 carrying Vietnamese astronaut Pham Tuan, a propaganda coup during the 1980 Olympics. They returned to Earth in Soyuz-36 leaving the EO-4 crew to do another docking port swap in Soyuz-37. On Sep 19 Soyuz-38 arrived with the first astronaut of African descent, Arnaldo Tamayo Mendez of Cuba. On Sep 30, after the return of Soyuz-38, Progress-11 docked with the station, while Soyuz-37 returned the EO-4 crew to Earth on Oct 11.
The DOS station remained in orbit with Progress-11 attached. The next visitor was Soyuz T-3 in November, the first use of a Soyuz T for a primary expedition and the first three-person crew since the Soyuz-11 accident. The EO-5 visit was brief and Soyuz T-3 returned to Earth in December just after Progress-11 was jettisoned.
In Jan 1981 Progress-12 docked with the station and was used to raise its orbit. Soyuz T-4 delivered the EO-6 crew in March and they were visited by two guest crews in old-style Soyuz ships: Soyuz-39 in March with a Mongolian and Soyuz-40 in May with a Rumanian. EO-6 crew returned to earth on May 26 ending the human occupation of the DOS-5 station.
On 1981 Jun 19 the experimental TKS spaceship Kosmos-1267 docked at the forward port. It remained there until the complex was deorbited a year later.
