An unmanned Soyuz capsule has launched to the ISS to replace a damaged space shuttle at the International Space Station.
The Soyuz MS-23 took off from Russia’s Baikonur Cosmodrome in Kazakhstan.
She has around 430 kilograms of cargo on board for the crew, including medical equipment and equipment for scientific experiments.
The capsule is scheduled to dock with the ISS on Sunday at 2 a.m. (Swiss time).
The unusual mission became necessary because the MS-22 ferry docked at the ISS has a leak – probably caused by a micrometeorite. The liquid escaping from the cooling system made the return of two Russians and one American seem risky.

The plan now is that cosmonauts Sergei Prokopyev and Dmitri Petelin and NASA astronaut Frank Rubio, who came to the ISS in September with the MS-22, are expected to return to Earth with the MS-23 in the autumn. In the meantime, the damaged MS-22 capsule could fly back from the ISS unmanned.
American-Russian cooperation in space

Russia and the United States have been working closely together on the space station around 400 kilometers above the earth for more than 20 years, but the relationship got into a serious crisis exactly one year ago because of the Russian invasion of Ukraine.

According to the state agency TASS, the scientific and technical council of the Russian space agency Roskosmos decided a few days ago “after detailed consultations” to continue using the Russian segment of the ISS until 2028.
