Today’s launch opportunity has been scrubbed because of poor weather. “The launch director and team have made the determination to scrub today’s launch attempt,” Mike Curie, NASA launch commentator reported. Next launch attempt is Sunday morning at 1:52 a.m. EDT. Our countdown coverage will begin at 12:45 a.m. EDT on the launch blog and on NASA TV. The forecast calls for a 40 percent chance of acceptable conditions for the Sunday attempt.
