Video: Falcon 9 fires engines at pad 39A ahead of Es’hail 2 launch (members only)

SpaceX rolled out a Falcon 9 rocket Sunday night to pad 39A at NASA’s Kennedy Space Center in Florida for liftoff with the next 60 Starlink internet satellites, but officials have pushed back the launch until Wednesday.

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.

Iranian government officials admitted Sunday that an attempt to place a small Earth-imaging satellite into orbit was unsuccessful, the fourth consecutive launch failure for the country’s space program.
