The leak has since been determined to be coolant, and ground teams at Mission Control in Moscow continue to assess the leak from the aft end of the Soyuz MS-22 spacecraft. Following the ongoing analysis, NASA and Roscosmos will continue to work together to determine the next course of action. The crew members aboard the space station are safe and were not in any danger during the leak. The Soyuz MS-22 spacecraft transported NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into space after launching on September 21 from the Baikonur Cosmodrome in Kazakhstan.
