Thanks to CTOnews.com netizen yeung233 for the clue delivery! CTOnews.com A coolant leak on the Soyuz MS-22 spacecraft aboard the International Space Station (ISS) led to the emergency cancellation of the extravehicular mission of astronauts Sergey Prokopyev and Dmitri Petelin.

NASA International Space Station officials said the ground team at Moscow Mission Control Center would continue to evaluate coolant leaks detected at the tail end of the Alliance MS-22 spacecraft. As a result, the planned December 14 spacewalk was cancelled in order to assess fluids and potential effects on the integrity of the Soyuz spacecraft. The International Space Station is in good condition.

CTOnews.com has learned that the Soyuz MS-22 spacecraft launched from Baikonur Cosmodrome in Kazakhstan on September 21, carrying American astronaut Frank Rubio and Russian cosmonauts Sergey Prokopyev and Dmitri Petelin into space.
