1.10.4.2 Progress Missions to Salyut 6
For information on Salyut operations during these Progress missions, see section 2.7.3.
| Progress 1 | January 20-February 8, 1978 | |
| Can be seen as a prototype for subsequent Progress missions. Progress 1 docked with the aft port of the Salyut 6 space station on January 22. The aft port carried fixtures for transferring fuel and gases from Progress to the station. The crew vented air from Progress 1’s tanks into the station, and unloaded nearly 1300 kg of food, replacement parts, scientific instruments, and other supplies from the orbital module. They then worked in concert with the TsUP to pump fuel and oxidizer into Salyut 6. Propellants were pumped into each separate tank in turn. After refueling was complete, but while the Progress and station were still docked, the propellant lines linking Progress and Salyut were vented to space to prevent residual propellant from contaminating the station’s docking surfaces. After that, they loaded the orbital module with refuse. On February 5 and 6, Progress 1’s engine was used to make adjustments to Salyut 6’s orbit. On February 6, Progress 1 backed away from Salyut 6. A deorbit burn took place over the U.S.S.R. on February 8, followed by destructive reentry over the Pacific Ocean. | ||
| Progress 2 | July 7-August 4, 1978 |
| Progress 3 | August 7-23, 1978 |
| Progress 4 | October 3-26, 1978 |
| Progress 5 | March 12-April 5, 1979 | |
| Served as a receptacle for contaminated fuel from the damaged Salyut 6 propulsion system. | ||
| Progress 6 | May 13-June 9, 1979 |
| Progress 7 | June 28-July 20, 1979 | |
| Delivered the KRT-10 radio telescope, which was deployed from the rear port of Salyut 6 after Progress 7 backed away. Cameras on Progress 7 televised
deployment. | ||
| Progress 8 | March 27-April 26, 1980 |
| Progress 9 | April 27-May 22, 1980 | |
| Before Progress 9, cosmonauts carried water into Salyut stations in 5 kg bottles. Progress 9 was the first to pump water directly into the new Rodnik system tanks aboard Salyut 6.[1] | ||
| Progress 10 | June 29-July 19, 1980 |
