Watch: SpaceX's Falcon Heavy rocket launches from Florida SpaceX successfully launched a Falcon Heavy rocket from Kennedy Space Center in Florida for the first time in three years on Tuesday morning. CAPE CANAVERAL, Fla. - The first SpaceX Falcon Heavy rocket to launch in three years soared above a thick blanket of fog Tuesday morning sending a top-secret U.S. national security mission to space. SpaceX launched the world's most powerful rocket at 9:41 a.m. using more than 5 million pounds of thrust to rise above the dense fog and into the blue sky. Inside the Falcon Heavy fairings, or nose cone, was the U.S. Space Force spacecraft known as USSF-44. Ahead of the launch, forecasters with the Space Force 45th Weather Squadron predicted a nearly perfect morning for liftoff with a 90% chance of favorable liftoff conditions. Dense fog surrounded the Kennedy Space Center launchpad 39A and the rocket Tuesday morning. Still, fog is not a launch weather constraint and the countdown continued without issue.

As the boosters came back down, they break the sound barrier, sending shock waves – or sonic booms – that can be heard from Kennedy Space Center as far inland as Orlando. SpaceX successfully landed both side boosters at Cape Canaveral Landing Zone 1 generating a double sonic boom. The boosters returned to land about 8 minutes after launch. However, the rumble of the landing took even longer to reach areas farther from the landing site. The landings marked the 150th and 151st rocket boosters SpaceX has successfully recovered post liftoff. What is Falcon Heavy launching? SpaceX image The U.S. Space Force contracted SpaceX to launch the USSF-44 mission. It marks the first national security mission for the Falcon Heavy. According to the Space Force, the spacecraft has multiple payloads designed to test space technology for future programs. "The Falcon Heavy is an important element of our overall lift capability, and we're very excited to be ready for launch," Program Executive Officer for Assured Access to Space Brig. Gen. Stephen Purdy, said ahead of launch. "Every national security launch brings important capabilities to the nation, and investments in space capabilities increase the effectiveness of operations in every other domain – the U.S. military is better connected, more informed, faster and precise because of space."
