NASA on Friday delayed space shuttle Discovery's launch by at least one day to give engineers time to plug a small helium gas leak and a nitrogen gas leak aboard the craft.
Discovery's countdown to launch an 11-day resupply mission to the International Space Station was scheduled to begin at 3 p.m. Friday. Liftoff for its 39th and final mission was supposed to take place on Monday at 4:40 p.m. from Kennedy Space Center. Now, it won't happen before Election Day at the earliest.
NASA officials said the leaks are in the Orbital Maneuvering System pod, the system used to maneuver the shuttle in orbit, but they said they don't think that the leaks are serious.
