Thunderstorms delay space shuttle launch again

Thunderstorms forced NASA to call off Sunday evening’s launch of shuttle Endeavour, the fourth delay for the space station construction mission.

The launch team came within minutes of sending Endeavour and seven astronauts to the international space station. But storms quickly moved in from the west and violated NASA’s safety rules, and managers halted the countdown. They will try again Monday, despite an outlook calling for more bad weather.
