CAPE CANAVERAL, Fla. (AP) - The countdown is under way, but the weather is not cooperating with Saturday's scheduled launch of space shuttle Endeavour.
Air Force meteorologists say the forecast is still 60% "no go" for Saturday evening. That's because of a risk of rain and thunderstorms. The weather improves to 60% positive for Sunday.
Endeavour's launch was put off twice last month by a hydrogen gas leak that has since been fixed.
Seven astronauts are set to do five spacewalks to install the final piece of a Japanese lab on the international space station.
