Mike Curie/NASA Launch Commentator: This is Shuttle Launch Control at 1:55 a.m. Eastern daylight time.
We are scrubbing the launch attempt for today. The troubleshooting efforts have not resulted in a
significant decrease in the amount of liquid hydrogen, or I should say, gaseous hydrogen,
that's being detected outside of the Ground Umbilical Carrier Plate -- the same area
where we experienced a leak the last launch attempt.
STS-127 Launch Director Pete Nickolenko has just given the team a go to scrub the
launch attempt after two more attempts to open the vent valve,
once again, displayed much higher than expected amounts of gaseous hydrogen.
