Updated after scrubs.<\/strong><\/p>\n

SpaceX\u2019s Falcon 9 rocket is set for liftoff from Cape Canaveral on Friday evening, heading due east over the Atlantic Ocean to deliver the SES 9 television broadcast satellite into orbit 31 minutes later.<\/p>\n

The 229-foot-tall rocket is poised for launch from Complex 40 at 6:35 p.m. EST (2335 GMT) Friday at the opening of a 91-minute launch window.<\/p>\n

Perched atop the rocket is the SES 9 communications satellite, a 11,620-pound (5,271-kilogram) spacecraft made by Boeing, ready to beam television programming, data services and mobile connectivity to homes, businesses, ships and airplanes in the Asia-Pacific and the Indian Ocean region.<\/p>\n

The timeline below outlines the launch sequence for the Falcon 9 flight with SES 9. It does not include times for the experimental descent and landing attempt of the first stage booster, which SpaceX says is unlikely to succeed due to the high speed required for the SES 9 launch.<\/p>\n

SpaceX\u2019s landing platform is positioned about 400 miles (650 kilometers) east of Cape Canaveral for the first stage landing attempt, which is expected around 10 minutes after liftoff.<\/p>\n

\"The
The Merlin engine shuts down after a short burn to put the SES 9 satellite in the proper orbit for deployment. SpaceX has programmed the engine to burn until the second stage\u2019s propellant tanks are nearly empty instead of timing the engine cutoff to put the SES 9 spacecraft into a specific orbit. The adjustment allows the rocket to put SES 9 into the highest orbit possible.<\/figcaption><\/figure>\n

T+0:31:24: SES 9 Separation<\/b><\/p>\n

\"The
The SES 9 satellite separates from the Falcon 9 rocket in an orbit with a predicted high point of about 39,300 kilometers (24,400 miles), a low point of 290 kilometers (180 miles) and an inclination of 28 degrees. Due to the decision to burn the second stage nearly to depletion, there is some slight uncertainty on the orbital parameters based on the exact performance of the launcher.<\/figcaption><\/figure>\n
