(CNN) -- A gaseous hydrogen leak on the space shuttle Endeavour forced NASA to cancel Saturday's planned launch, the space agency said.
NASA officials postponed Saturday's scheduled launch of space shuttle Endeavour because of a leak.
Shuttle managers will assess the leak and meet at 2 p.m. ET Sunday to discuss what steps to take next, including setting a new launch date, NASA said. They planned a news conference after the meeting, the space agency said.
The earliest the shuttle could be ready to launch now is Wednesday, NASA said, but there is a conflict on that date with the scheduled launch of the Lunar Reconnaissance Orbiter/Lunar Crater Observation and Sensing Satellite.
Endeavour, carrying seven astronauts and a key component for Japan's Kibo science laboratory, is scheduled for a mission to the International Space Station.
