4K video: Wide-angle view of Falcon 9 hotfire

Two South Korean Earth-watching satellites will ride Ariane 5 rockets into orbit in 2018 and 2019 after Arianespace beat SpaceX in a competition to launch the spacecraft.

An Atlas 5 lifts off at dawn creating a spectacular sky show as it races toward orbit carrying the fifth Advanced Extremely High Frequency (AEHF 5) communications satellite for the U.S. Air Force.

The mission was the second of potentially three Falcon 9 flights set to take place this week. Liftoff from pad 40 at Cape Canaveral Space Force Station happened at 10:35 p.m. EDT (0235 UTC).
