NASA and Roscosmos continue to evaluate an external leak that occurred Dec. 14, 2022, from the Roscosmos Soyuz MS-22 spacecraft docked to the Rassvet module of the International Space Station. Roscosmos has identified the source of the leak as the external cooling loop of the Soyuz.

As part of the ongoing evaluation and investigation, Roscosmos flight controllers conducted a successful test of the Soyuz MS-22 thrusters at 3:08 a.m. EST Friday, Dec. 16. The systems that were tested were nominal, and Roscosmos assessments of additional Soyuz systems continue. Temperatures and humidity within the Soyuz spacecraft, which remains docked to the Rassvet module, are within acceptable limits.

NASA is supporting the ongoing investigation with the use of the Canadarm2 robotic arm to provide additional viewing of the Soyuz exterior on Sunday, Dec. 18. To accommodate this change in plans, NASA has determined a new target date for the upcoming U.S. spacewalk to install an International Space Station Roll-Out Solar Array (iROSA), which was originally scheduled for Monday, Dec. 19. The spacewalk will take place Wednesday, Dec. 21.

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.

The leak was first detected around 7:45 p.m. EST Dec. 14, when data pressure sensors in the cooling loop showed low readings. At that time, Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin were preparing to conduct a spacewalk. The spacewalk was cancelled, so the cosmonauts did not exit the space station or become exposed to the leaking coolant. From data analysis and cameras aboard the space station, the majority of fluid had leaked out by yesterday, Dec. 15, around 1:30 p.m. EST.

An international partnership of space agencies provides and operates the elements of the  International Space Station (ISS). The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken.
