    Mission managers scrubbed another attempt to launch the space shuttle Endeavour today as thunderstorms within 20 miles of Pad 39A at Kennedy Space Center, Fla., violated flight rules.

    The pad was "red" for lightning within 10 nautical miles of the pad, violating launch constraints, and thunderstorms within 20 nautical miles of the runway the orbiter would have to use in an unlikely but always possible return-to-launch-site abort. The "field mill" rule setting limits on electrical fields that could trigger lightning during a launch also were in violation, and conditions were worsening when the scrub was called.

    "The vehicle and our teams were ready, but the weather has just bitten us again," said Launch Director Mike Leinbach in calling the scrub out to the crew on the pad.

    "When the time is right we'll be here and be ready," said Endeavour commander Mark Polansky.

    Crew were assessing their systems to determine if another attempt can be made on Tuesday.
