| EVA and Progress 2. Progress 2 delivered, among other items, the Kristall kiln. Fuel transfer was carried out under TsUP control, leaving the cosmonauts free to do other things. On July 29, the Fotons conducted an EVA to retrieve detectors and materials samples launched attached to the Salyut 6 hull. The EVA lasted 2 hr, 5 min. Afterwards, the Fotons replenished the Salyut 6 air supply, which had been depleted by the EVA, from tanks in Progress 2. They then filled Progress 2 with trash. It separated and deorbited on command from the TsUP.[1] |

| Transfer from aft port to front port. The Fotons conducted the first transfer of a Soyuz from the aft port to the front port of a space station. This became a routine procedure. They undocked Soyuz 31 and backed off to 100-200 m distance. Then the TsUP commanded Salyut 6 to rotate laterally 180°, placing the front port before the waiting Soyuz 31 spacecraft. The operation freed the aft port for additional Progress freighters.[2] | |||
