As such, the relief Soyuz crew wasn't fully trained yet for the accelerated MS-23 launch in February 2023, necessitating a wait until yet another spacecraft (MS-24) was ready in September to carry them to the ISS.Īfter the relief crew arrived, the three MS-22/MS-23 astronauts then returned home in the replacement spacecraft, having been required to spend 12 months on the ISS instead of six to accommodate the spacecraft changeover. Soyuz crews typically launch every six months. The Russian agency determined it was best to quickly send up an empty replacement Soyuz, MS-23, and return MS-22 back to Earth for analysis. Roscosmos next examined its options for the spacecraft, then set to carry three astronauts home in early 2023, including American astronaut Frank Rubio, who would inadvertently spend a record-setting 371 consecutive days aboard the ISS due to the Soyuz malfunction. The extravehicular activity was canceled due to the risk to the cosmonauts. The most dramatic of the two other Russian leaks was a December 2022 incident aboard the Soyuz MS-22 spacecraft, shortly before a scheduled Roscosmos spacewalk two cosmonauts were in fact already suited up to exit the station just before the leak happened. McDowell is an astrophysicist and astronomer who also tracks launches, re-entries and other major spaceflight milestones. One is whatever, two is a coincidence, three is something systemic," McDowell said in the report. "You've got three coolant systems leaking - there's a common thread there. Roscosmos has said the last two incidents were likely due to micrometeroid impacts, although Harvard-Smithsonian space analyst Jonathan McDowell told The Guardian he suspects there is a "systemic" problem. The Nauka leak is the latest in a string of ISS Russian equipment coolant escapes in recent months. Russian cosmonauts Sergey Prokopyev and Dmitry Petelin work to deploy a radiator for the Nauka multipurpose laboratory module during a spacewalk at the International Space Station on May 12, 2023.
