Today's Return to Flight launch of Space Shuttle Discovery has been postponed due to 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.

NASA managers are currently meeting to evaluate the sensor issue. More information will be released at a press conference scheduled for no earlier than 4:30 p.m. EDT this afternoon from Kennedy Space Center, Fla. The press conference will be broadcast on NASA TV.

Eileen Collins is the commander for the Return to Flight mission and leads an international crew of six astronauts. Discovery is set for a 12-day flight to deliver equipment and supplies to the International Space Station. The STS-114 mission comes after a two and a half year initiative to reinforce the orbiters and improve the safety of the Space Shuttle fleet.
