Progress MS-01

[7] The Russian Progress is an uncrewed cargo resupply spacecraft that is largely based on the crewed Soyuz.

This latest update in the line of Progress spacecraft, also to be introduced on the crewed Soyuz craft, is largely focused on communications and navigation systems that are upgraded using modern electronics.

After launch, ground controllers were able to communicate the Progress MS-01 via a Russian Luch data relay satellite in geosynchronous orbit.

The spacecraft is still compatible with the Soyuz-U rocket that is being phased out in a soft transition to the newer version, alternating flights between the two to iron out any problems with no significant interruption of the supply chain to International Space Station (ISS).

[8] Afterward, Progress is loaded with trash and no-longer-needed items before the hatch is closed and the spacecraft undocks.

[10] On 1 July 2016 Progress MS-01 was briefly undocked to perform a test of the TORU manual control system.

Alexey Ovchinin then manually flew Progress back to the port with capture occurring at 6:05 UTC.
