Russian Spacecraft to Manually Dock with ISS After Antenna Problem Forces Change

Manual Docking Procedure Initiated After Antenna Malfunction

MOSCOW, March 23 (Reuters) - An unmanned Russian cargo spacecraft has a problem with an antenna so it will have to be manually docked when it reaches the International Space Station (ISS), Russia's Roscosmos state space corporation said in a statement.

Details of the Launch and Antenna Issue

A Soyuz-2.1a rocket launched the Progress MS-33 cargo spacecraft on Sunday from Baikonur in Kazakhstan but a problem with one of the KURS automated rendezvous antennas was identified, Roscosmos said.

Manual Docking Operation

Russian cosmonaut Sergei Kud-Sverchkov, the current ISS commander, will manually dock the cargo ship on Tuesday at about 13:35 GMT, Roscosmos said. 

Cosmonaut Training and Preparedness

"A manual approach of ships to the ISS is regularly practiced by cosmonauts in training," said Oleg Kononenko, head of Russia's Cosmonaut Training Center.

System Status and Troubleshooting Efforts

NASA said all other systems are operating as normal and that Roscosmos will continue troubleshooting the antenna. 

Cargo and Crew Details

The cargo ship is carrying about 2.5 tonnes of food, water, fuel, oxygen and supplies for the crew aboard the ISS.

Current ISS Crew Members

There are currently seven crew aboard the ISS including Russians Kud-Sverchkov, Sergei Mikayev and Andrei Fedyaev, U.S. astronauts Christopher Williams, Jessica Meir and Jack Hathaway, and France's Sophie Adenot.

Key Takeaways

  • Progress MS‑33 launched March 22, 2026 aboard Soyuz‑2.1a, but a KURS‑NA antenna failed to deploy, disabling full automated docking functionality (en.wikipedia.org)
  • Russian ISS commander Sergei Kud‑Sverchkov will manually dock the spacecraft on March 24, 2026 using the TORU manual backup system, a procedure routinely practiced (en.wikipedia.org)
  • Despite the antenna issue, all other systems are operating normally, and Roscosmos alongside NASA will continue diagnostics while the spacecraft carries roughly 2.5 tonnes of supplies to the seven-person ISS crew (en.wikipedia.org)
