Eventually NASA checks the air leak down on the ISS, but it is not yet fixed

The ISS has a small but pesky air leak.


The mystery of the long-running space is almost solved. NASA and ISS crews have been harassed before the weather leaked, which was seen in late 2019. The leak was only recently reported. NASA in search of a ka track dish below it. A new round of tests eventually shortens the space.

NASA astronauts Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Evan Wagner have conducted a series of tests to include closing hatches around the station so that NASA can monitor air pressure in each section. His recent efforts led NASA to the core of the Zvezda service module.

The Russian-made Zvezda service module includes live quarters with life support, communications and propulsion systems. Additional work is underway to find the exact source of the leak, NASA said in a statement on Tuesday.

The space agency insisted the crew had no immediate threat from the leak.

Flight controllers woke up astronauts and cosmonauts late Monday night so they appeared to be “increasing in size at length.” The crew used an ultrasound leak detector to collect data for analysis.

Leaks may be more consistent than they appeared before. “The size of the leak known overnight is then attributed to a change in the temporary temperature at the station, as the overall rate of the leak remains the same,” NASA said.

The crew has returned to regular activities, including getting ready for a busy October on the ISS. The station will expect new cargo deliveries as well as new crew of astronauts and cosmonauts. SpaceX is also set to unveil it The first operational crew dragon mission for the ISS In late October.

Isolating a leak into a specific service module is a big step. Once the exact location is found, NASA can investigate repair options and eventually end the long, leakage saga.
