HOUSTON (NASA PR) — Late Monday night, the Expedition 63 crew was awakened by flight controllers to continue troubleshooting a small leak on the International Space Station that appeared to grow in size. Ground analysis of the modules tested overnight have isolated the leak location to the main work area of the Zvezda Service Module. Additional work is underway to precisely locate the source of the leak.
The leak, which has been investigated for several weeks, poses no immediate danger to the crew at the current leak rate and only a slight deviation to the crew’s schedule.
NASA astronaut and station commander Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner were instructed to move into the Russian segment to collect data at various locations in the Russian modules. The size of the leak identified overnight has since been attributed to a temporary temperature change aboard the station with the overall rate of leak remaining unchanged.
Previous leak checks were conducted in the modules in the U.S. segment of the station.
