The Soyuz MS-22 spacecraft Konstantin Tsiolkovsky, which launched Expedition 68 crewmembers Sergey Prokopyev, Dmitry Petelin, and NASA’s Frank Rubio on Sept. 21, 2022, returned to Earth in automated mode after suffering a leak in a coolant loop last December.
Cosmonauts Prokopyev and Petelin were preparing to conduct an EVA on the Russian segment of the International Space Station on Dec. 15 when controllers noticed a leak in the Soyuz MS-22 spacecraft’s service module. Flakes coming from the area of the coolant loop were noticed on live camera feeds pointing toward the spacecraft, and as a result, the EVA was canceled.
