How Russian cargo ships test automated docking systems at the International Space Station
In short: This video covers the operational testing of automated rendezvous systems on Russian Progress cargo ships. It explains how these unpiloted spacecraft perform complex docking maneuvers, including the use of backup manual control systems when primary automated technology encounters technical issues during approach.
The Progress spacecraft serves as a vital logistics vehicle for the International Space Station, often carrying supplies or removing waste. Testing upgraded rendezvous systems is critical for refining automated docking procedures. For instance, the Progress 47 mission in July 2012 successfully redocked to the Pirs compartment after an initial attempt was aborted due to a system malfunction.
When primary automated systems like the KURS rendezvous antennas fail to deploy, as seen with the Progress 94 mission in March 2025, backup protocols are activated. Cosmonauts utilize the Telerobotically Operated Rendezvous System (TORU), a manual control interface located within the Zvezda Service Module, to safely guide the craft to the station's docking port.
