Video: 4K video replay of SpaceX’s CRS-21 launch (members only)

Launching the commercial WorldView 4 Earth-imaging satellite for DigitalGlobe, a United Launch Alliance Atlas 5 rocket thunders away from California’s Vandenberg Air Force Base today at 10:30 a.m. local time (1:30 p.m. EST; 1830 GMT).

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral early Tuesday, heading due east over the Atlantic Ocean to deliver the EchoStar 23 communications satellite into orbit 34 minutes later.

Look back on the Oct. 30 launch of a SpaceX Falcon 9 rocket with this gallery of photos showing the 229-foot-tall launcher lifting off from pad 39A at NASA’s Kennedy Space Center in Florida.
