Launch from the Baikonur Cosmodrome; landing 160 km east of Dzheskasgan.

Following a one day solo flight Soyuz T-9 docked with Salyut 7-Kosmos 1443 on June 28, 1983. The cosmonauts became the second resident crew of the station.

Almost immediately after docking at Salyut 7’s aft port, the crew entered Kosmos 1443 and commenced transferring the 3.5 tons of cargo lining its walls to Salyut 7. This included solar arrays to augment Salyut 7's power, to have been installed by the crew of the aborted Soyuz T-8.

On July 27, 1983 a small object struck a Salyut 7 viewport. It blasted out a 4 mm crater, but did not penetrate the outer of the window's two panes. It was not clear, if it was orbital debris or from a meteor shower.

On August 16, 1983 Soyuz T-9 was repositioned by rotating Salyut 7, freeing the aft port for Progress 17. Unmanned supply vessel Progress 17 to Salyut 7 docked with Salyut 7 on August, 19 1983 at 13:47:00 UTC, undocked on September 17, 1983 at 11:44:00 UTC and was destroyed in reentry on September 17, 1983 at 23:43:00 UTC.
During refuelling by Progress 17, the main oxidiser line of the Salyut 7 propulsion system ruptured. The seriousness of the malfunction was not immediately apparent in the West. However, after the malfunction, Salyut 7 had to rely on the main propulsion systems of visiting Progress freighters for maintaining orbital altitude.

The crew loaded Kosmos 1443’s VA capsule with 350 kg of experiment results and hardware no longer in use. It could have held 500 kg, had they had that much to put in. Kosmos 1443 then undocked, in spite of Western predictions that the FGB component would remain attached to Salyut 7 as a space station module. The VA capsule soft-landed on August 23, 1983 and the FGB component continued in orbit until it was deorbited over the Pacific Ocean on September 19, 1983.

On September 26, 1983 a Soyuz spacecraft (Soyuz T-10A) bearing Vladimir Titov and Gennadi Strekalov stood atop a Soyuz booster at Baikonur Cosmodrome. This was the Soyuz T-8 crew, again set to accomplish their mission of augmenting the Salyut 7 solar arrays. About 90 sec before planned launch time, the booster caught fire. Vladimir Titov and Gennadi Strekalov, who had been unable to dock with Salyut 7 on the Soyuz T-8 mission, were rocketed away from the pad by the Soyuz escape tower, while the booster exploded behind them, free of the booster, which exploded on the pad.

Progress 18 resupplied the station on October 22, 1983 - November 13, 1983. The freighter boosted Salyut to 326 x 356 km orbit on November 04, 1983, undocked on November 13, 1983 at 03:08:00 UTC and was destroyed in reentry on November 16, 1983 04:at 18:00 UTC.

The first EVA was performed by Vladimir Lyakhov and Aleksandr Aleksandrov on November 01, 1983 (2h 50m). The cosmonauts added a new panel to one edge of Salyut 7s top (center) array.
Following the second failure of Vladimir Titov and Gennadi Strekalov to reach the station, it was up to Vladimir Lyakhov and Aleksandr Aleksandrov to carry out the much-delayed solar array augmentation EVAs despite the fact they had not trained for it on the ground. They used two Yakor foot restraints installed on Salyut 7 near the base of the solar array.

Both cosmonauts went out of the space station for another spacewalk on November 03, 1983 (2h 55m). This EVA was a repeat of the first. Together the two new panels increased Salyut 7s available electricity by 50%.
