“We will try to put a finer point in our troubleshooting plan,” Todd said, explaining that the team is dealing with the same leak as before, rather than a new one.
Russia’s space agency Roscosmos has confirmed that the leak comes from one of its service modules.
NASA astronaut Chris Cassidy and Roscomos cosmonauts Anatoly Ivanishin and Ivan Wagner performed the tests on board.
“The size of the leak, identified overnight, has since been due to a temporary change in temperature on board the station, with the overall rate of leaks remaining unchanged,” NASA said in a statement Tuesday.
While crew members experience comfortable pressure while living in the orbital laboratory, the space station experiences small air leaks over time.
Regular pressure reductions are possible thanks to the nitrogen tanks that are included in the cargo delivery missions that deliver them to the space station.
The next supply mission is scheduled to arrive this weekend. The unscrewed cargo ship Northrop Grumman Cygnus will launch from Wallops Flight Center in the US state of Virginia on Thursday night.
Then the crew members will spin. NASA astronaut Kate Rubins and Russian cosmonauts Sergei Ryzhikov and Sergei Kud-Sverchkov will leave the Baikonur Cosmodrome in Kazakhstan on October 14 and board the space station, while Cassidy, Wagner and Ivanishin will leave the space station on October 21. on the ground .
The trio will spend 195 days together on the space station after their launch in April.
Then, on October 23, the SpaceX Crew-1 mission will launch to the space station, transporting NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker and the astronaut of the Japanese space agency Soichi Noguchi.
