Soyuz 29 was the fifth mission, the fourth successful docking, and the second long-duration crew for the orbiting station. Commander Vladimir Kovalyonok and flight engineer Aleksandr Ivanchenkov established a new space-endurance record of 139 days. The crew returned on board Soyuz 31, which had been swapped by a crew launched in August who returned in Soyuz 29. The second long-duration mission to Salyut 6 was launched into orbit on 15 June 1978. The space station had been vacant for three months since the record-breaking mission of Soyuz 26 ended after 96 days. The crew successfully docked on 17 June and Kovalyonok and Ivanchenkov reactivated the station. Kovalyonok, who was aboard the failed Soyuz 25 mission to Salyut 6, became the first person to visit the same station twice. They switched on the station's air regenerators and thermal regulation system, and activated the water recycling system to reprocess water left aboard by Soyuz 26. De-mothballing Salyut 6 occurred simultaneously with the crew's adaptation to weightlessness, and required about one week. Cosmonauts V. Kovalyonok and A. 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.
