NASA and its Russian counterpart have recognized 50 “areas of concern” associated to a long-running leak aboard the house station, a media report states.
The leak has been ongoing since 2019 within the Russian section of the Worldwide House Station (ISS) and was the main target of a brand new report from NASA’s Workplace of the Inspector Basic (OIG) printed in September. Whereas NASA and Roscosmos are addressing the leak, it stays a prime “security danger” for astronauts on board, the OIG report said.
NASA officers, talking in an unique with the Washington Publish, stated they’re monitoring 4 cracks and 50 different “areas of concern” on the ISS. The cracks have “all been coated with a mixture of sealant and patches” by Roscosmos, NASA famous in an announcement to the newspaper, and fixes are ongoing. Nonetheless, the leaking space is the highest danger, at a 5 on a scale of 5, in NASA’s inner danger assessments, the OIG said.
“Now we have conveyed the seriousness of the leaks a number of instances, together with after I was in Russia earlier this yr,” affiliate administrator Jim Free added in an interview with the Publish. Because the leaks are adjoining to a hatch, Free added that Roscosmos acquiesced to a NASA request to shut the hatch as a lot as doable: “We have come to a compromise that they shut it within the night.”
NASA astronauts additionally stay on the U.S. facet of the orbiting advanced to be near their escape automobiles, in case of the necessity of evacuation, the company famous in its assertion to the information outlet. That stated, NASA has burdened repeatedly that the leak poses no instant menace to astronauts.
“Not an affect proper now on the crew security or automobile operations, however one thing for everyone to concentrate on,” ISS program supervisor Joel Montalbano stated in a information convention in February 2024 when the leak briefly elevated to 2.4 kilos per day, up from a historic low of 0.2 kilos per day.

The leak has been ongoing for 5 years and patches have been ongoing because it was first uncovered; company officers famous in a Sept. 27 livestreamed briefing that restore work lowered the excessive leak noticed in April 2024 by roughly a 3rd.
The escaping air originated in a service module switch tunnel in Russia’s Zvezda module that launched in 2000.

The ISS is meant to final till 2030 to serve each NASA’s staffing wants, and likewise to offer industrial low Earth orbit analysis. Within the following decade, NASA hopes to have a set of business house stations able to take over operations.
NASA’s OIG is monitoring a number of different dangers that might imperil conserving the ISS going that lengthy, starting from a sudden micrometeoroid strike to provide chain points.
SpaceX has been tasked to construct a big Dragon-type spacecraft to take away the ISS from orbit, in a contract awarded by NASA earlier this yr. The OIG said will probably be trying to study extra concerning the schedule, prices and dangers related to the brand new automobile and the deorbiting plan.
