Upon arriving at Salyut 6, Kovalyonok and Ivanchenkov switched on the station’s air regenerators and thermal regulation system, and activated the water recycling system to reprocess water left aboard by the Tamyrs. De-mothballing Salyut 6 occurred simultaneously with the crew’s adaptation to weightlessness, and required about one week. On June 19 Salyut 6 was in a 368 km by 338 km orbit. Onboard temperature was 20 °C, and air pressure was 750 mmHg (100 kPa). Soon after this, Kovalyonok and Ivanchenkov performed maintenance on the station’s airlock, installed equipment they brought with them in Soyuz 29’s orbital module, and tested the station’s Kaskad orientation system. The station operated in gravity-gradient stabilized mode June 24–June 26 to avoid attitude control system engine firings which could cause interference with a 3-day smelting experiment using the Splav-01 furnace. The previous crew installed the furnace in the intermediate compartment so it could operate in vacuum.

During their stay on board of Salyut 6 two visiting crews docked with the station.
