“We will try to put a more precise point on our troubleshooting plan,” Todd said, explaining that the team is dealing with the same loss as before rather than a new one.
Russian space agency Roscosmos confirmed that the leak came from one of its service modules.
NASA astronauts Chris Cassidy and Roscomos cosmonauts Anatoly Ivanishin and Ivan Vagner carried out the tests on board.
“The size of the leak identified overnight has since been attributed to a temporary temperature change aboard the station with the overall leak rate remaining unchanged,” NASA said in a blog post Tuesday.
While crew members experience comfortable pressure while living in the orbiting laboratory, the space station experiences tiny air leaks over time.
Regular repressurization is possible thanks to the nitrogen tanks included in the cargo replenishment missions that deliver them to the space station.
The next refueling mission is expected to arrive this weekend. The Northrop Grumman Cygnus unmanned cargo aircraft will be launched Thursday evening from the Wallops Flight Facility in the US state of Virginia.
Then the crew members will rotate. NASA astronaut Kate Rubins and Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov will depart from the Baikonur Cosmodrome in Kazakhstan on October 14 and dock at the space station, while Cassidy, Vagner and Ivanishin will leave the space station on October 21 and return to Earth. . .
The trio will have spent 195 days together on the space station after launch in April.
Then, on October 23, the SpaceX Crew-1 mission will be launched on the space station, carrying NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japanese space agency astronaut Soichi Noguchi.
