List of Progress missions

In addition, three custom Progress M variants were launched to deliver ISS modules Pirs in 2001, Poisk in 2009 and Prichal in late 2021.

All Progress spacecraft traveling to Salyut 6 were launched by the Soyuz-U, and dockings were to the rear port of the station.

Veteran enthusiast Robert Christy[3] suggests this may have been an error due to confusion with a TKS spacecraft which later became Kosmos 1686.

[4] 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.

Progress M1-4 spent 25 days in free flight, prior to redocking with the same port.

For more than three decades, over 167 Progress robot spacecraft have provided logistical support to the Soviet/Russian space program in low Earth orbit.
