At 1:55 a.m. EDT, launch managers called a scrub, canceling today’s planned launch of space shuttle Endeavour on its STS-127 mission. Despite troubleshooting efforts, engineers were unable to achieve a decrease in the liquid hydrogen leak associated with the external fuel tank’s ground umbilical carrier panel. This is the same location where a similar leak resulted in a launch scrub on June 13.
