That sucks... bigtime.

Gentlemen (and ladies),

Let's all wish them luck and hope that they get this beautiful girl off the ground tomorrow.

the launch has been scrubbed due to a problem with the ECO early cut-off fuel sensors. a problem with these sensors was noted during the fueling tests on Discovery earlier this year.

The failure was with the LH2 ECO Sensor #2. The sensors presently shows 'WET' with the tank full. At ~L-3 hours, a test command is sent to transition the sensors from WET to DRY to check the sensors out. Sensor #2 failed to transition to DRY. This is in violation of the launch criteria (basically, we are NO GO if there is anything anomalous with these sensors, failed hard, intermittent or transient).

Please continue discussion of this scrub under the News & Events forum thread, Launch Scrub.
