Live coverage: Ariane 5 blasts off with two Intelsat satellites

Watch a time-lapse video of the 229-foot-tall (70-meter) Falcon 9 rocket being lifted into place on pad 39A in readiness for the launch of the SES 10 communications satellite. This will be a major milestone for SpaceX as it will mark the first time a flown Falcon 9 first stage has been reused.

SpaceX technicians at Cape Canaveral are readying for the first launch of an upgraded Falcon 9 rocket configuration next week, a mission that will debut changes to make the launcher safer for astronauts and make it easier — and less expensive — for the company to reuse first stage boosters.
