Discovery Won't Launch Before Sunday
NASA has announced that the space shuttle Discovery's earliest launch window will be on Sunday, July 17 at 1914 UTC (2:14 pm EDT); although, it could be much later. A problem with a fuel gauge on the shuttle's external tank halted the countdown on Wednesday. Engineers have so far been unable to find the source of the problem. The shuttle's launch window will last until the end of the July, and then opens up in September again.
