Dec 15 (Reuters) - A planned routine spacewalk by two Russian cosmonauts aboard the International Space Station was called off on Wednesday after flight controllers noticed a stream of particles spewing from a docked Soyuz spacecraft, a NASA webcast showed.

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

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

Somebody call a plumber.

Roscomos was never able to stanch the leak of the external cooling loop, so the leak only stopped when there was no coolant left. In the immediate aftermath, Russian flight controllers attempted to use the European robotic arm, attached to the Russian segment of the station, to observe the aft end of the Soyuz where the leak occurred. This 11-meter arm did not provide conclusive data.

The external cooling loop of the Soyuz MS-22 spacecraft is now inoperable. Effectively, this means that a separate cooling loop that keeps the interior of the Soyuz cool—for the comfort of the passengers and the avionics—can no longer easily dump heat into space. Because these flight computers are embedded fairly deeply into the guts of the spacecraft, it's difficult to cool them with the ambient atmosphere of the space station with the hatch open.

At present, the space station is in "high beta," which means it's in a period of full illumination from the Sun during the entirety of its orbit. Over time, this may cause the flight computers to overheat. For this reason, some consideration is being given to an early departure by the crew of Soyuz MS-22, cosmonauts Sergey Prokopyev and Dmitri Petelin and NASA's Frank Rubio. They could leave the station as early as this month if flight controllers determine there is the potential for the flight computers or other sensitive avionics to be damaged before the spacecraft's planned return in March 2023.

 

No official confirmation yet but it looks like Soyuz MS-22 will be declared too unsafe to return crew.

The plan.

Maybe the Cosmonauts don't want to go home only to be given a Kalashnikov and sent to a "special military operation"?

 

And a rusty one at that.
