ISS Leak: Russian Space Agency Acknowledges 'Slight' Temperature Rise

European robotic arm controlled by astronaut Anna Kikina inspects the Soyuz MS-22 spacecraft after the detection of a leak that led to the cancellation of a spacewalk.

The Russian space agency Roscosmos on Friday acknowledged a “slight” rise in temperature aboard a spacecraft docked to the International Space Station (ISS), which it said was harmless, two days after a leak potentially due to a micrometeorite impact.

A number of tests were performed on the Soyuz MS-22 spacecraft, according to Roscosmos, including measuring the temperature in the living space of the ship. It is now 30°C, the Russian space agency said on Telegram.

This is a slight change in temperature, continued Roscosmos, which says that this situation is not critical for the operation of equipment and the comfort of the station crew.

But the whole issue is to determine if the ship will still be able to bring back to Earth two Russian cosmonauts and their American colleague Frank Rubio, whose mission is scheduled to end in March 2023.

The temperature in the spacecraft is currently maintained by means of the Russian segment of the ISS, Roscosmos clarified.

The Soyuz MS-22 leak came on Wednesday when Russian cosmonauts Sergei Prokopiev and Dmitry Petelin were preparing for a spacewalk, which was ultimately canceled.

Russian astronauts Sergey Prokopyev and Dmitry Petelin performed a spacewalk outside the International Space Station ( ISS), on November 17, 2022, successfully.

The source of the leak has been identified as coming from the Soyuz cooling system, and the liquid was presumed to be coolant.

Images broadcasts by the US space agency had clearly shown a jet of white particles escaping abundantly into space from the ship. Most of the fluid had escaped by Thursday, NASA said Friday.

Temperatures and humidity inside the Soyuz spacecraft […] are within acceptable limits, the US agency also reassured.

According to the NASA, a successful test of the ship's engines was completed on Friday, but further checks remain in progress.

A spacewalk scheduled for Monday has been pushed back to Wednesday, to allow the station's Canadian robotic arm to be used to provide more exterior images of the Soyuz on Sunday, NASA said.

Besides the crew who arrived on board of the Soyuz, four other people are currently in the ISS: the Russian Anna Kikina, the Americans Nicole Mann and Josh Cassada, and the Japanese Koichi Wakata. They traveled with an American SpaceX vessel.

The ISS is one of the few fields of cooperation still in progress between Moscow and Washington since the beginning of the Russian offensive in Ukraine, launched on February 24, and the Western sanctions that followed.
