Endeavour Clears Hurdle For July 11 Launch
A test fueling of space shuttle Endeavour's external tank
revealed no gaseous hydrogen leaks, verifying recent repairs were
successful, NASA managers confirmed during a Wednesday afternoon
news conference at NASA's Kennedy Space Center in Florida.
The tanking test began at 0652 EDT Wednesday. During the next
three hours, teams in the Launch Control Center watched closely for
signs of a leak as liquid oxygen and liquid hydrogen poured into
the massive orange tank. Previous attempts to launch Endeavour on
the STS-127 mission were scrubbed by a leak in the area of the
Ground Umbilical Carrier Plate, which attaches a gaseous hydrogen
vent line to the external tank. Crews worked to investigate and
repair the problem.
"There were absolutely no leak indications whatsoever noted on
the two leak detectors," said Launch Director Pete Nickolenko.
"We'll continue to look at the data, and our next step is to move
Endeavour's launch is targeted for July 11 at 1939 EDT.
