After suffering through a month’s delay, NASA enjoyed a trouble-free countdown for space shuttle Discovery, all set to blast off on a space station construction mission Wednesday night. Launch director Mike Leinbach said Monday that the countdown was going smoothly, and forecasters put the odds of good launching weather at 90 percent. “The team is anxious to go,” he said. Shuttle managers had so little to discuss at Monday morning’s launch review at that they wrapped up in under an hour.
