In space, no one can hear you scream, but you can hear an air leak. In old science fiction movies, air leaks on spaceships and stations reveal themselves as convenient holes to slap a patch on, but on the complex International Space Station (ISS), it isn't that simple. NASA is working on a new system for detecting the ultrasonic noise of an air leak quickly before it turns into a dangerous race against time.
