NASA has a new state-of-the-art space capsule on the launch pad and a new high-tech countdown clock to go with it for Thursday, Dec. 4, 2014, morning's liftoff of Orion on an unmanned orbital test flight. NASA spokesman George Diller said the old clock, while still working, had become too expensive to fix and maintain. (AP Photo/Wilfredo Lee, File)
