The Soyuz spacecraft connected to the Earth-facing facet of the Worldwide Area Station has suffered a coolant leak. A deliberate spacewalk by Russian cosmonauts Sergey Prokopyev and Dmitri Petelin has been cancelled, in accordance with NASA.
The spacewalk was scheduled to happen at 6 p.m. PT. to maneuver a heat-dissipating radiator from the Rassvet module to Russia’s recently-installed Nauka multi-purpose laboratory module however a stream of particles was seen within the imaginative and prescient of the MS-22 Soyuz previous to the cosmonauts exiting the station. NASA famous the astronauts on board are protected and the area station is in good situation via a tweet on Wednesday night.
“Tonight’s spacewalk has been cancelled due to an noticed leak of what’s believed to be a cooling substance,” mentioned Rob Navias, from NASA communications, in the course of the broadcast.
The spacecraft carried each Prokopyev and Petelin to the station on Sep. 21, together with NASA astronaut Frank Rubio, for the Soyuz MS-22 mission.
Navias famous in the course of the broadcast that the flakes have been “indicative of a leak” however the substance has not been confirmed. The leak was coincident with a drop in strain in one of many exterior cooling loops of the spacecraft. Specialists at Roscosmos in Moscow are evaluating the leak and can assess whether or not it has induced any injury to the integrity of the Soyuz spacecraft.
That is the second time the spacewalk to maneuver the radiator has been cancelled. Initially, the cosmonauts have been going to conduct their work on Nov. 25 however there was an issue with the water cooling loops within the cosmonaut’s fits.
