wednesday's scheduled launch of the shuttle discovery was delayed due to a fuel leak. the STS-119 launch has been rescheduled for tonight at 7:43 pm EDT. preparations for launch are fully underway and NASA reports that "more than 500,000 gallons of liquid hydrogen and liquid oxygen have been transferred to their respective containers inside the 154-foot tall orange tank" and no leaks are evident!
good luck to the discovery STS-119 crew!
