Photos: Falcon takes flight

Two pioneering communications satellites purely powered by plasma rocket thrusters lifted off from Cape Canaveral aboard a Falcon 9 launcher Wednesday, starting missions to broadcast video across Asia and Latin America, and improve navigation for airplanes crossing the United States.

SpaceX raised a Falcon 9 rocket vertical Tuesday on pad 39A at NASA’s Kennedy Space Center, positioning the launch vehicle for a flight Wednesday carrying 57 more Starlink Internet satellites and two commercial Earth-imaging microsatellites for BlackSky.

SpaceX scrubbed the launch of a nearly 7.5-ton Intelsat communications satellite Sunday after a computer-triggered abort halted the countdown in the final 10 seconds.
