Launch preparations for the SES 10 communications satellite, the first spacecraft to ride a reused Falcon 9 booster to space, are on track for a late March blastoff from Florida, officials said.

Launching its 10th mission this year, SpaceX delivered an Intelsat communications satellite to a high-altitude transfer orbit Wednesday with a Falcon 9 rocket launched from Kennedy Space Center in Florida.
