Photos: Atlas 5 rolls out for launch

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.

The U.S. Space Force’s third new-generation GPS 3-series navigation satellite has arrived in Florida for final processing and fueling ahead of a launch currently targeted for April 29 aboard a SpaceX Falcon 9 rocket.

A rocket engine with a long pedigree marked a big milestone on Monday. It’s 60 years since the hydrogen-fueled RL10 engine debuted onboard a Centaur upper stage launched from Cape Canaveral on Nov. 27, 1963.
