Countdown Begins Again For Space Shuttle Endeavour

CAPE CANAVERAL, Fla. (AP) - NASA has begun another countdown for space shuttle Endeavour. But stormy weather could stall the weekend launch.

The space agency will try to launch Endeavour Saturday night, following a pair of delays last month caused by a hydrogen gas leak. The leak has since been plugged. But now, launch controllers will have to deal with thunderstorms.

Forecasters put the odds of acceptable weather at just 40% for a Saturday evening launch. The outlook is only slightly better for Sunday.

The seven astronauts assigned to the 16-day mission returned to the Kennedy Space Center Tuesday. They'll deliver and install the final piece of Japan's lab at the international space station.
