List of Progress missions
This is a list of missions conducted by Progress automated spacecraft. Progress is an uncrewed Russian cargo spacecraft which has been used since 1978 to deliver supplies to Soviet space stations Salyut 6, Salyut 7, Mir, and later to the International Space Station. All launches have occurred from the Baikonur Cosmodrome.
More than 178 flights have been launched, all except Progress M-12M, Progress M-27M and Progress MS-04/65P have reached their destinations, with no injuries or loss of life after launch; Progress M-12M and MS-04 failed during launch, whereas Progress M-27M experienced a spacecraft loss of attitude control while in orbit. The Progress M-24 spacecraft collided with Mir during a failed docking attempt in 1994, and Progress M-34 caused serious damage to the Spektr module when it drifted off course during a docking test in 1997.
The spacecraft uses the automatic Kurs docking system for rendezvous with its destination space station, where crew are used in supervisory roles, only intervening using the manual TORU system when problems occur. Five variants of the Progress spacecraft have been flown so far: Progress 7K-TG, Progress-M 11F615A55, Progress-M1, Progress-М 11F615A60 and Progress-MS. In addition, three custom Progress M variants were launched to deliver ISS modules Pirs in 2001, Poisk in 2009 and Prichal in late 2021.
Flights
Flights to Salyut 6
All Progress spacecraft traveling to Salyut 6 were launched by the Soyuz-U, and dockings were to the rear port of the station. Progress 7 deployed the KRT-10 astronomy satellite.Flights to Salyut 7
Kosmos 1669 is the only Progress spacecraft to have received a Kosmos designation, which is usually reserved for the military, experimental and failed spacecraft.Veteran enthusiast Robert Christy suggests this may have been an error due to confusion with a TKS spacecraft which later became Kosmos 1686. Astronautix.com suggests that the spacecraft may have gone out of control shortly after launch, but then been recovered after the Kosmos designation had been applied. Alternatively, it could have been given the designation as it was used to test modifications that would be used on future Progress missions. Some news agencies reported that it was a free-flying Progress-derived spacecraft, or that it was a new type of spacecraft derived from the Progress.
