NASA to explain test results; launch likely July 11

NASA plans to host a 1 p.m. news conference to discuss this morning's fuel-loading test at Kennedy Space Center.

Since no leaks of hydrogen gas were reported during the roughly three-hour operation, officials are expected to confirm a July 11 launch date for Endeavour's 16-day International Space Station assembly mission.

Gas leaks scrubbed launch attempts on June 13 and June 17, but repairs since then apparently worked during today's test.

Mike Moses, chairman of the Mission Management Team, and Pete Nickolenko, launch director for Endeavour's STS-127 mission, will appear at the briefing.

The targeted liftoff time July 11 is 7:39 p.m., in the middle of a 10-minute launch window.

The top goal for Endeavour's crew of seven is to complete assembly of Japan's Kibo science lab complex.

The shuttle will also deliver American astronaut Tim Kopra to the station to join its crew of six, and bring home Japanese astronaut Koichi Wakata.
