SpaceX successfully completed a countdown dress rehearsal and launchpad hot fire engine test yesterday in preparation for the next commercial launch of its Falcon 9 rocket on November 25.

This was the first such fueling at Kennedy of the Falcon 9.

Update: This article gives some details about why the second engine burn of the upper stage rocket did not occur on the previous Falcon 9 launch, and what SpaceX has done to fix the problem. That failure caused speculation that the engine exploded at the attempt.

It is essential that engine functions in space on the November 25 launch in order for SpaceX to deliver its commercial satellite to its proper geosynchronous orbit.
