STS-127: Hydrogen Leak Forces Second Scrub

After lightning delayed Shuttle Endeavour's fueling by almost 3 hours, the old gaseous hydrogen leak issue surfaced again. Mission managers declared a scrub at 1:55 EDT this morning. NASA reports:

Endeavour Launch Now Targeted for July 11

Space shuttle Endeavour's STS-127 second launch attempt was cancelled early Wednesday, June 17 due to a liquid hydrogen leak associated with the ground umbilical carrier panel. It's the same location where a similar leak scrubbed Endeavour's first launch attempt on June 13.

Endeavour's next launch attempt is targeted for July 11 at 7:39 p.m. EDT.
