Last-minute problem keeps SpaceX rocket, astronauts grounded

Last-minute technical trouble forced SpaceX to call off Monday's attempt to launch four astronauts to the International Space Station for NASA. The countdown was halted with just two minutes remaining until liftoff from Kennedy Space Center. With just a split second to blast off, there was no time to deal with the problem, which involved the engine ignition system. (AP Video shot by Stephen Smith)
