ISS May Have A Leak

Rio writes "The International Space Station is experiencing a slow, steady drop in air pressure, and American and Russian flight controllers are investigating possible causes of the leak. The Local 6 News report says Mission Control notified astronaut Michael Foale and cosmonaut Alexander Kaleri about the leak just before their bedtime late Monday afternoon. Mission Control first noticed the drop in pressure Jan. 1 and said the data showed a daily decline of about 2 millimeters of mercury. As of Monday, the pressure had declined a total of nine millimeters. That is equivalent to about one-quarter of a pound per square inch, said NASA spokesman James Hartsfield."
