(18 Feb 2017) SpaceX will have to wait at least another day to launch from NASA's historic moon pad. Last-minute rocket trouble forced SpaceX to halt Saturday's countdown at Florida's Kennedy Space Center. The unmanned Falcon rocket remains at Launch Complex 39A, waiting to soar on a space station delivery mission. It's the same pad where Americans flew to the moon almost a half-century ago, and where the shuttle program ended in 2011. This will be SpaceX's first Florida launch since a rocket explosion last summer. The accident during prelaunch testing heavily damaged that pad. SpaceX turned to Launch Complex 39A - which it leases from NASA - to resume flights. The company hopes to launch astronauts from 39A next year. The next launch attempt could come as early as Sunday morning.
