Discovery had been scheduled to blast off at 1.36 a.m. (0536 GMT) from Kennedy Space Center in Florida to transport new equipment and experiments to the International Space Station.

The safety risk for Discovery's seven astronauts and the shuttle was too high, NASA said.
The space shuttle is now scheduled to lift off Wednesday at 0510 GMT.
