Mission Controllers Assess Soyuz Coolant Leak

Ground teams at Mission Control in Moscow continue to assess a coolant leak detected from the aft end of the Soyuz MS-22 spacecraft docked to the International Space Station. As a result, the planned Dec.14 Roscosmos spacewalk was canceled to allow time to evaluate the fluid and potential impacts to the integrity of the Soyuz spacecraft.

NASA and Roscosmos will continue to work together to determine the next course of action following the ongoing analysis. The crew members aboard the space station are safe, and were not in any danger during the leak.

The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into space after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.
