Engineers are troubleshooting a small air leak aboard the International Space Station that was discovered last September, NASA reported Thursday. While it poses no safety threat, the lab’s three-man crew plans to seal themselves in the Russian segment of the station this weekend to help engineers pin down the leak’s location.
“All the space station hatches will be closed this weekend so mission controllers can carefully monitor the air pressure in each module,” NASA said in a blog post. “The test presents no safety concern for the crew.
“The test should determine which module is experiencing a higher-than-normal leak rate. The U.S. and Russian specialists expect preliminary results should be available for review by the end of next week.”
Expedition 63 commander Chris Cassidy and his two Russian crewmates, Anatoly Ivanishin and Ivan Vagner, were launched to the station aboard the Soyuz MS-16/62S spacecraft April 9. They’ve had the lab complex to themselves since the two-man crew of a SpaceX Crew Dragon capsule undocked and returned to Earth on Aug. 2.
