Endeavour launch scrubbed again
Hydrogen vent system not in such good shape
NASA has scrubbed today's planned launch of space shuttle Endeavour - the second such knock-back due to a gaseous hydrogen leak and despite assurances yesterday that the vehicle was "in good shape" to go.
The agency canned the lift-off at 05:55 GMT after detecting an escape in at the "Ground Umbilical Carrier Plate" (in pic) - part of the system "used to carry excess hydrogen safely away from the launch pad" and at "the same location where a similar leak resulted in a launch scrub on June 13".
NASA reports: "Vent valve troubleshooting took place for about an hour before it became clear the problem could not be solved."
Deputy Space Shuttle Program Manager LeRoy Cain said: "We're going to step back and figure out what the problem is and go fix it. Once we get it fixed, and we're confident that we have a solution that's going to work and allow us to go fly safely, then we'll proceed forward."
