(Reuters) -A routine spacewalk by two Russian cosmonauts aboard the International Space Station (ISS) was called off as it was about to begin after flight controllers noticed a stream of liquid spewing from a docked Soyuz spacecraft, a NASA webcast showed.
The spray of fluid, which was visible in NASA's live video feed as a torrent of snowflake-like particles emanating from the rear section of the Soyuz MS-22 capsule, was described by a NASA commentator as a coolant leak.
