Before the planned spacewalk, the docked Soyuz spacecraft started leaking/spraying/venting large quantities of droplets into space. This corresponded with an instrument warning about low coolant pressure levels. Roscosmos decided to cancel the planned spacewalk, repressurize the airlock, and bring the cosmonauts back inside the ISS. They are also determining what to do about the Soyuz spacecraft.
Russian Spacewalk 56 plans to move a radiator from the Rassvet module to the Nauka multipurpose laboratory module at the International Space Station. Spacewalkers will be Sergey Prokopyev and Dimitri Petelin. Spacewalk will last about 7 hours Postponed from Nov 25, Dec 6. Scrubbed on Dec 14 due to a Soyuz coolant leak.
The two cosmonauts were informed through radio communication from a representative of Russia’s Mission Control Operations near Moscow. That the spacewalk had been postponed while scientists investigated the nature and cause of the leak.
The spacewalk was postponed due to the leak. Which started on Thursday, according to NASA commentator Rob Navias, who was hosting the live webcast from NASA’s Johnson Space Center in Houston.
On August 30, the ISS detected a fall in atmospheric pressure. The Soyuz MS-09 spacecraft was linked to the orbiting station when the crew discovered a two-millimeter hole in the hull by individually inspecting the compartments and add-on modules. It was repaired that day’s evening with different levels of epoxy glue. The pressure level stabilized. The workers added another coat of sealant to the patch on August 31.
Dmitry Rogozin, CEO of Roscosmos, said that a drill had destroyed the Soyuz MS-09 spacecraft from the inside. To find those ultimately responsible, the space rocket company Energia is undertaking an investigation. Investigations are being conducted to determine who had complete access to the spacecraft, what tasks were completed, and who oversaw them.
