UPDATE 9:02am | SpaceX has already begun loading gear onto the Falcon 9 rocket at pad 39A.
As the sun rose Saturday over Kennedy Space Center in Florida, the unmanned Falcon rocket stood at Launch Complex 39A, ready to soar.
SpaceX is sending up a load of space station supplies from the exact spot where Americans flew to the moon almost a half-century ago.
The pad was last used in 2011 for NASA's final space shuttle flight.
This is SpaceX's first launch from Florida since a rocket explosion Sept. 1.
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.
