NASA discovers possible leak on Space Station E-mail

A perceived minor leak is being observed by NASA engineers after an inspection found a slight loss of air, about 3 pounds (1.3 kilograms) per day, in the International Space Station.  


The leak was discovered in a connecting compartment between the Harmony (Node 2) utility hub and Destiny laboratory module.

NASA does not consider the leak a safety problem to the International Space Station (ISS) Expedition 16 three-person crew or to any astronauts on future shuttle missions to the space station. However, they are seriously looking into the issue.

In fact, they are looking into the theory that the leak may not be real but only, what is being called, a “phantom signal” from the station’s sensors.

They base this theory on a check of the leak taken on Wednesday, November 29, 2007. An ultrasonic leak detector did not find any indication of a leak.

The ISS crew will check the seals between the Harmony module and its docking port on Thursday, and will perform other inspection over the upcoming week.

According to a Space.com article (“NASA Tracks Possible Space Station Leak”), Lynette Madision, a spokesperson for the NASA Johnson Space Center (Houston, Texas), “Nobody is really concerned about this.”
