The launch of space shuttle Endeavour's STS-127 mission to the International Space Station is on hold due to a leak associated with the gaseous hydrogen venting system outside the external fuel tank. The system is used to carry excess hydrogen safely away from the launch pad at NASA's Kennedy Space Center in Florida. At 12:26 a.m. EDT Saturday, managers officially scrubbed the launch for at least 96 hours.

The earliest the shuttle could be ready for liftoff is June 17, however there is a range conflict on that date with the scheduled launch of the Lunar Reconnaissance Orbiter/Lunar Crater Observation and Sensing Satellite from Cape Canaveral Air Force Station, Fla.

Mission STS-127 is the 32nd flight dedicated to station construction, and the final of a series of three flights dedicated to the assembly of the Japanese Kibo laboratory complex.The STS-127 payload is the Kibo Japanese Experiment Module Exposed Facility and Experiment Logistics Module Exposed Section.
