A Soyuz Capsule on ISS is Leaking Coolant Into Space - by spacewriter
The Soyuz MS-22 crew ship is pictured docked to the Rassvet module. In the background, the Prichal docking module is attached to the Nauka multipurpose laboratory module. Courtesy NASA.Roscosmos first noticed the leak on the Soyuz crew ship at 7:45 p.m. EDT on December 14th. That’s when multiple sensors showed low readings from the coolant loop. The cosmonauts delayed and ultimately cancelled their walk, in large part to avoid contact with the leaking coolant.
The cause of the leak is still under investigation. Ground crews are still assessing whether and how much damage the outgassing ammonia has done to the exterior of the space station as well as the spacecraft itself. In particular, they’ll want to know if there’s been any effect on solar panels, radiators, insulating blankets, and other parts of the station.
Roscosmos is monitoring Soyuz spacecraft temperatures, which are still within acceptable limits. NASA and the Russian space agency are coordinatingof the affected spacecraft and planning further inspections to evaluate the location of the leak and possibly what caused it to happen. Plans for an additional inspection of the Soyuz exterior using the station’s Canadarm2 robotic arm are underway.
along with the NASA, the Japanese Aerospace Exploration Agency, the European Space Agency, and the Canadian Space Agency.
