Sergei Krikalev, a veteran cosmonaut who serves as the director of crewed space flight programs at Roscosmos, said a meteorite striking one of external radiators of the Soyuz MS-22 capsule could have caused the coolant to escape.The malfunction could affect the performance of the capsule’s coolant system and the temperature in the equipment section of the capsule but doesn’t endanger the crew, Krikalev said in a statement.NASA emphasized on Thursday that “none of the crew members aboard the space station was in danger, and all conducted normal operations throughout the day.”Group casts doubt on Amazon's claims of reducing plasticCosmonauts' spacewalk canceled at space station due to leak$698M deal to end Monsanto PCB pollution lawsuit in OregonSweden: chimps euthanized after escaping from zoo enclosureIt seconded the Russian statement, saying that “the external radiator cooling loop of the Soyuz is the suspected leak source.”“Roscosmos is closely monitoring Soyuz spacecraft temperatures, which remain within acceptable limits,” NASA said in a statement, adding that “NASA and Roscosmos continue to coordinate external imagery and inspection plans to aid in evaluating the external leak location.Plans for an additional inspection of the Soyuz exterior using the station’s Canadarm2 robotic arm are underway.”As Russian cosmonauts Sergey Prokopyev and Dmitri Petelin were about to venture outside the station on a planned spacewalk early Thursday, ground specialists saw a stream of fluid and particles on a live video feed from space, along with a pressure drop on instruments, emanating from the Soyuz capsule.Along with Prokopyev, Petelin and Rubio, four other crew members are currently on the space outpos: NASA astronauts Nicole Mann and Josh Cassada, the Japan Aerospace Exploration Agency’s Koichi Wakata and Anna Kikina of Roscosmos."
