Russian house capsule leak probably because of micrometeorite strike, official says

A coolant leak detected from the aft finish of the Russian house capsule docked to the Worldwide House Station was probably attributable to a micrometeorite strike, in response to a Russian house official. 

Sergei Krikalev, a veteran cosmonaut who serves because the director of crewed house flight packages at Roscosmos, stated Thursday {that a} meteorite hanging one of many radiators of the Soyuz MS-22 capsule might have triggered the coolant to flee.

Krikalev stated in an announcement that the malfunction might have an effect on the efficiency of the capsule’s coolant system and the temperature within the tools part of the capsule.

Roscosmos and NASA have each stated that the incident had not posed any hazard to the station’s crew.

“There have been no different adjustments in parameters on the Soyuz spacecraft and the station, so there isn’t a menace for the crew,” he stated.

The leak, nonetheless, compelled the cancellation of a deliberate spacewalk for Russian cosmonauts Sergey Prokopyev and Dmitri Petelin.

Floor specialists noticed a stream of fluid and particles on a dwell video feed from house, in addition to a stress drop on devices. 

“Floor groups at Mission Management in Moscow proceed to evaluate a coolant leak detected from the aft finish of the Soyuz MS-22 spacecraft docked to the Worldwide House Station. Consequently, the deliberate Dec.14 Roscosmos spacewalk was canceled to permit time to guage the fluid and potential impacts to the integrity of the Soyuz spacecraft,” NASA wrote in a weblog put up.

“NASA and Roscosmos will proceed to work collectively to find out the following plan of action following the continued evaluation,” the company stated. “The crew members aboard the house station are secure, and weren’t in any hazard through the leak.”

The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Prokopyev and Petelin into house after launching from Kazakhstan on Sept. 21.

It serves as a lifeboat for the crew.

Together with Prokopyev, Petelin and Rubio, 4 different crew members are at present on the house outpost: NASA astronauts Nicole Mann and Josh Cassada, the Japan Aerospace Exploration Company’s Koichi Wakata and Anna Kikina of Roscosmos.

Krikalev stated the station’s future operations would depend upon an evaluation of the capsule’s situation.

“Choices concerning the future flight program might be made on the idea of that evaluation,” he stated.

In November, the James Webb House Telescope workforce introduced that it might regulate its statement technique to keep away from its mirror being struck by the tiny house rocks.
