During preparations for this evening’s planned spacewalk by Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin, ground teams noticed significant leaking of an unknown substance from the aft portion of the Soyuz MS-22 spacecraft docked to the Rassvet module on the International Space Station. The spacewalk has been canceled, and ground teams in Moscow are evaluating the nature of the fluid and potential impacts to the integrity of the Soyuz spacecraft, which carried Prokopyev, Petelin, and NASA astronaut Frank Rubio into space after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.
