On Wednesday, Dec. 14, an exterior leak was detected from the Roscosmos Soyuz MS-22 spacecraft docked to the Rassvet module on the Worldwide House Station. The exterior radiator cooling loop of the Soyuz is the suspected leak supply.
The Roscosmos Mission Management group in Moscow postponed Wednesday night’s deliberate spacewalk with two cosmonauts to guage the scenario and information from the Soyuz spacecraft. Not one of the crew members aboard the house station was at risk, and all carried out regular operations all through the day.
Roscosmos is carefully monitoring Soyuz spacecraft temperatures, which stay inside acceptable limits. NASA and Roscosmos proceed to coordinate exterior imagery and inspection plans to assist in evaluating the exterior leak location. Plans for a further inspection of the Soyuz exterior utilizing the station’s Canadarm2 robotic arm are underway.
The leak was first detected round 7:45 p.m. EST Dec. 14 when information from a number of stress sensors within the cooling loop confirmed low readings. At the moment, cosmonauts Sergey Prokopyev and Dmitri Petelin had been making ready to conduct a spacewalk. The cosmonauts didn’t exit the house station, and no crew members had been uncovered to the leaking coolant.
The Soyuz MS-22 spacecraft carried NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev and Dmitri Petelin into house after launching from the Baikonur Cosmodrome in Kazakhstan on Sept. 21.
The crew aboard station accomplished regular operations Thursday, together with taking part in science investigations and analysis, in addition to configuring instruments forward of a deliberate U.S. spacewalk on Monday, Dec. 19. Specialists are working by way of robotic plans forward of Monday’s spacewalk to greatest optimize for upcoming station operations and the Soyuz inspection.
A Roscosmos spacewalk scheduled for Dec. 21 is indefinitely postponed because the group continues its investigation of the Soyuz spacecraft.
