The launch came a day after the original flight was scrubbed because of high shear winds at the launch site. Arabsat-6A lifted off at 6:35 pm EDT (22:35 GMT) from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida. The launch occurred without any major technical malfunctions and delivered its payload into its transfer orbit 34 minutes into the flight.
As the second stage coasted over the night side of the Earth, the three Falcon boosters that make up the first stage of the rocket carried out a complex de-orbiting maneuver that sent the two side boosters back to Cape Canaveral Air Force Station in Florida, where they made a successful, near-simultaneous ground landing. Meanwhile, the core booster, which flew higher and farther downrange than the other two, deorbited and made a dramatic landing on the deck of the drone ship "Of Course I Still Love You," which was stationed in the Atlantic Ocean.
This booster recovery is the first time all three first stage units have managed to land safely. During the Falcon Heavy's maiden flight in 2018, the two side boosters were recovered, but the core booster crashed when three of the engines failed, causing it to crash into the sea at 300 mph (483 km/h).
