SpaceX Uses Falcon 9 Again to Launch Rocket, Incredible Footage

SpaceX's latest mission's off to a good start, thanks to the same rocket booster that launched NASA astronauts on their journey to the International Space Station in May ... and here's the incredible footage.

The Falcon 9 launched the ANASIS-II Mission rocket on Monday around 5:30 PM ET from the Cape Canaveral Air Force Station in Florida, this time to set a communications satellite into orbit.

Videographer Ryan Chylinski utilized a slo-mo camera and zoom lens to capture the stunning moment ... and the telescope-tracking vid shows the rocket in great detail.

As we reported ... Falcon 9 launched 2 American astronauts -- Doug Hurley and Bob Behnken -- into orbit on May 30, then returned to the ground on a remote droneship.
