The predawn launch from NASA’s Kennedy Space Center of a Falcon Heavy rocket June 25 was the first nighttime liftoff of SpaceX’s heavy-lifter, the most powerful launcher currently operational anywhere in the world. The Falcon Heavy’s two side boosters returned to Cape Canaveral less than nine minutes later.

The world’s most powerful operational rocket flashed to life at 2:30 a.m. EDT (0630 GMT) Tuesday and climbed into a moonlit summer sky from pad 39A at NASA’s Kennedy Space Center in Florida, the same site where the Apollo 11 astronauts left Earth for their historic moon landing nearly 50 years ago.

SpaceX’s third Falcon Heavy rocket took off from the Kennedy Space Center in a predawn launch Tuesday, delivering two dozen research and weather observation spacecraft into orbit on a marathon three-and-a-half mission for the U.S. Air Force. The mission included the successful landing of the Falcon Heavy’s two side boosters back at Cape Canaveral, and a SpaceX recovery boat netted part of the rocket’s payload fairing for the first time.

SpaceX’s Falcon Heavy rocket rolled out of its hangar and up the ramp to pad 39A at NASA’s Kennedy Space Center in Florida, then was raised vertical at the seaside launch complex early Monday in preparation for a late-night liftoff with two dozen weather observation and technology demonstration satellites.

On its third flight Monday night, SpaceX’s Falcon Heavy rocket will fly to three different orbits with two dozen spacecraft on a mission set to last more than six hours, prompting SpaceX founder Elon Musk to declare it the company’s “most difficult launch ever.”
