Shuttle launch postponed

NASA today delayed the launch of its first space shuttle mission since the 2003 Columbia disaster after discovering a problem with one of the shuttle's fuel sensors, NASA's launch commentator said.
"We will not be able to fly today," commentator George Diller said.

Discovery was fuelled and ready to launch as planned at 0551 AEST when the problem with the liquid hydrogen fuel sensor occurred at 0332 AEST.

The sensor is one of four that detects fuel levels when the tank is nearly empty.

The astronauts had just been strapped into their spaceship when mission controllers called off the launch.
