Unexplained leak from docked Soyuz spacecraft cancels Russian ISS spacewalk

(Reuters) – A planned routine spacewalk by two Russian cosmonauts aboard the International Space Station was canceled on Wednesday after flight controllers noticed a stream of particles ejected from a docked Soyuz spacecraft, a webcast from the ISS showed. POT.

A NASA commentator said the torrent of particles, which appeared to be coming from the rear section of the Soyuz MS-22 capsule, appeared to be spacecraft liquid, possibly coolant.

NASA said none of the crew members of the International Space Station (ISS) were thought to be in danger.

A Russian mission control operations official near Moscow was heard telling the two cosmonauts in a radio transmission that their spacewalk was canceled while engineers worked to determine the nature and source of the leak.

NASA commentator on the live stream, Rob Navias, broadcasting from NASA Johnson Space Center in Houston, also said the spacewalk was canceled due to the leak, which began around 8:30 p.m. EST. (01:30 GMT on Thursday).
