NASA today prospered there Return to Flight launch of Space Shuttle Discovery, this was to be the first space shuttle mission since the space shuttle Columbia disintegrated on its return to Earth more than two years ago. The flight was postponed when at 1:32 p.m. EDT (1732 GMT) there was an issue with a low-level fuel cutoff sensor located inside the External Tank.

The sensor protects an orbiter’s main engines by triggering them to shut down in the event fuel runs unexpectedly low. Discovery was scheduled to lift off at 3:51 p.m. EDT (1951 GMT) from Kennedy Space Center in Cape Canaveral, Florida. NASA said there will be some opportunities to launch the craft tomorrow, though no date has been confirmed as of yet.
