Florida ? NASA will decide whether to try a night launch today of space shuttle Discovery at a crucial morning meeting before fueling the spacecraft.

Strong winds kept the shuttle and its seven astronauts grounded Friday, and low clouds scrubbed a launch on Thursday after a nail-biter of a countdown.

NASA was planning a second attempt at 7:47 p.m. CDT today, although there was only a 30 percent chance of acceptable weather because of high winds. Technicians on Friday fueled the shuttle’s power cells.

“If the weather forecast stays where it is now, it is more than likely they will be going for a launch attempt tomorrow,” astronaut James Kelly at Mission Control in Houston told the space station crew Friday afternoon. “It looks like the weather is similar to what it was yesterday, and as you know we came very close to getting it yesterday.”
