A coolant leak from a Russian space capsule hooked up to the Worldwide Area Station might have been attributable to a micrometeorite, a Russian space official mentioned Thursday.
Russia’s space company Roscosmos and NASA each mentioned that the incident hasn’t posed any hazard to the station’s crew. Nevertheless, the leak prompted a pair of Russian cosmonauts to abort a deliberate spacewalk earlier within the day.
Sergei Krikalev, a veteran cosmonaut who serves because the director of crewed space flight packages at Roscosmos, mentioned a meteorite putting certainly one of exterior radiators of the Soyuz MS-22 capsule might have triggered the coolant to flee.
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 however does not endanger the crew, Krikalev mentioned in a press release.
Krikalev mentioned Russian flight controllers had been assessing the scenario and following temperature indicators on the Soyuz. “There have been no different modifications in parameters on the Soyuz spacecraft and the station, so there isn’t any menace for the crew,” he mentioned.
NASA emphasised on Thursday that “not one of the crew members aboard the space station was in peril, and all carried out regular operations all through the day.”
It seconded the Russian assertion, saying that “the exterior radiator cooling loop of the Soyuz is the suspected leak supply.”
“Roscosmos is carefully monitoring Soyuz spacecraft temperatures, which stay inside acceptable limits,” NASA mentioned in a press release, including that “NASA and Roscosmos proceed to coordinate exterior imagery and inspection plans to help in evaluating the exterior leak location. Plans for a further inspection of the Soyuz exterior utilizing the station’s Canadarm2 robotic arm are underway.”
As Russian cosmonauts Sergey Prokopyev and Dmitri Petelin had been about to enterprise exterior the station on a deliberate spacewalk early Thursday, floor specialists noticed a stream of fluid and particles on a dwell video feed from space, together with a strain drop on devices, emanating from the Soyuz capsule.

Prokopyev, Petelin and NASA astronaut Frank Rubio used the capsule to reach on the Worldwide Area Station in September, and it serves as a lifeboat for the crew.
Krikalev mentioned the station’s future operations would rely on an evaluation of the capsule’s situation. “Selections in regards to the future flight program will probably be made on the premise of that evaluation,” he mentioned.
Together with Prokopyev, Petelin and Rubio, 4 different crew members are at present on the space outpos: NASA astronauts Nicole Mann and Josh Cassada, the Japan Aerospace Exploration Company’s Koichi Wakata and Anna Kikina of Roscosmos.
