SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Wednesday evening, heading due east over the Atlantic Ocean to deliver the SES 11/EchoStar 105 communications satellite into orbit 36 minutes later.

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.
