A leaky Soyuz capsule on the Worldwide Area Station test-fired its thrusters on Friday (Dec. 16) as Russian engineers investigated why it suffered an uncontrolled coolant spill this week.
The Russian-built Soyuz spacecraft, referred to as Soyuz MS-22, sprang a coolant leak Wednesday evening (Dec. 14) as two cosmonauts ready to take a spacewalk exterior the station. Russia’s house company Roscosmos canceled that spacewalk and postponed one other indefinitely because it investigates the reason for the coolant leak, which sprayed coolant particles into house from an exterior line on the capsule. On Friday, NASA additionally delayed a deliberate U.S. spacewalk to Dec. 21, a two-day slip, because the Soyuz work continues.
Russian engineers ordered the Soyuz MS-22 to fireplace its thrusters at 3:08 a.m. EST (0808 GMT) on Friday as a part of their investigation. The leak has been traced to an exterior coolant loop on the Soyuz spacecraft, NASA has mentioned.
“The programs that had been examined had been nominal, and Roscosmos assessments of extra Soyuz programs proceed,” NASA wrote in an replace (opens in new tab) Friday. “Temperatures and humidity inside the Soyuz spacecraft, which stays docked to the Rassvet module, are inside acceptable limits.”
Earlier within the day, a Roscosmos replace on Telegram (opens in new tab) said that temperatures contained in the Soyuz reached 86 levels Fahrenheit (30 levels Celsius) and had been inside operational limits, based on a Google translation from Russian. “This can be a slight temperature change,” Roscosmos wrote within the assertion, based on the interpretation.
The Soyuz MS-22 is docked to a Russian port on the Earth-facing facet of the station. It launched to the station in September to ship Russian cosmonauts Sergey Prokopyev and Dmitri Petelin and NASA astronaut Frank Rubio to the orbiting lab. It was Prokopyev and Petelin who had been planning to take a spacewalk when the leak started on Wednesday night. By noon Thursday (Dec. 15), a lot of the coolant had leaked out, NASA mentioned.
Russian engineers are working to find out the well being of the Soyuz spacecraft, however whether or not it could possibly nonetheless be used to return its crew to Earth as deliberate in 2023 is unclear.
Roscosmos has used a European-built robotic arm on Russia’s Nauka laboratory module on the station to examine the Soyuz capsule and reported some indicators of harm. NASA, in the meantime, will use the station’s Canadian-built Canadarm2 to examine the Soyuz on Sunday (Dec. 18).
