Soyuz spacecraft leak on space station forces cosmonauts to cancel spacewalk

A sizable coolant leak from one of Russia’s Soyuz crew spacecraft docked to the International Space Station forced cosmonauts to cancel a spacewalk as flight controllers on the ground worked to troubleshoot the problem.

The leak, which was traced back to the coolant system for the Soyuz MS-22 spacecraft, was first detected on Wednesday (Dec. 14) at 7:45 p.m. EST (0045 GMT on Dec. 15), about an hour and 40 minutes before Expedition 68 crewmates Sergey Prokopyev and Dmitry Petelin of the Russian federal space corporation Roscosmos were scheduled to begin a 6-hour, 40-minute spacewalk. The extravehicular activity (EVA) was called off after the two cosmonauts had already donned their spacesuits and were in the process of depressurizing the airlock to begin the outing.

Instead, Prokopyev and Petelin, who were never in any danger, repressurized the airlock and reentered the space station.

Cameras on the exterior of the space station showed a steady stream of frozen flakes being ejected from the Soyuz spacecraft into space. Although not yet confirmed, it was believed the source of the leak was an exterior coolant system located near the aft section of the vehicle.
