"Tonight's spacewalk with cosmonauts Sergey Prokopyev and Dmitri Petelin is cancelled as mission controllers evaluate the impact of a coolant leak seen on the Soyuz MS-22 crew ship. The space station is in good condition and the Expedition 68 crew is safe," NASA said on its Twitter page for updates from the ISS.
Russian space agency Roscosmos confirms that “the planned spacewalk of Russian cosmonauts Sergei Prokopyev and Dmitry Petelin from the International Space Station (ISS) has been canceled due to technical reasons”.
The cosmonauts were ordered to postpone the spacewalk for the second time in the last 30 days.
The spacewalk was initially planned for November 25 but was postponed until December 15 due to a malfunction in the pumps of a cooling system of one of the spacesuits.
