SpaceX's big new rocket blasted off Tuesday on its first test flight, carrying a red sports car aiming for an endless road trip past Mars.
The Falcon Heavy rose from the same launch pad used by NASA nearly 50 years ago to send men to the moon. With liftoff, the Heavy became the most powerful rocket in use today, doubling the liftoff punch of its closest competitor.
The three boosters and 27 engines roared to life at Kennedy Space Center, as thousands watched from surrounding beaches, bridges and roads, jamming the highways in scenes unmatched since NASA's last space shuttle flight.
At SpaceX Mission Control in Southern California, employees screamed, whistled and raised pumped fists into the air as the launch commentators called off each milestone.
Two of the boosters — both recycled from previous launches — returned minutes later for simultaneous, side-by-side touchdowns on land at Cape Canaveral.
Sonic booms rumbled across the region with the vertical landings. There was no immediate word on whether the third booster, brand new, made it onto an ocean platform 300 miles offshore.
SpaceX chief executive Elon Musk owns the rocketing Tesla Roadster, which is shooting for a solar orbit that will reach all the way to Mars.

As head of the electric carmaker Tesla, he combined his passions to add a dramatic flair to the Heavy's long-awaited inaugural flight. Ballast for a rocket debut is usually concrete or steel slabs, or experiments.
Cameras mounted on the car fed stunning video of the convertible floating high above the ocean with its driver, a space-suited dummy, named "Starman" after the Davie Bowie song.
A sign on the dashboard read: "Don't panic!" Bowie's "Life on Mars?" played in the background at one point.
"View from SpaceX Launch Control," Musk wrote via Twitter. "Apparently, there is a car in orbit around Earth."
Minutes later, he provided a livestream of "Starman" tooling around the blue home planet, looking something like a NASCAR racer out for a Sunday drive, with its right hand on the wheel and the left arm resting on the car's door.

On the eve of the flight, Musk told reporters the company had done all it could to maximize success and he was at peace with whatever happens: success, "one big boom" or some other calamity.
Musk has plenty of experience with rocket accidents, from his original Falcon 1 test flights to his follow-up Falcon 9s, one of which exploded on a nearby pad during a 2016 ignition test.
The Falcon Heavy is a combination of three Falcon 9s, the rocket that the company uses to ship supplies to the International Space Station and lift satellites. SpaceX is reusing first-stage boosters to save on launch costs. Most other rocket makers discard their spent boosters in the ocean.
Unlike most rockets out there, the Falcon Heavy receives no government funding. The hulking rocket is intended for massive satellites, like those used by the US military and major-league communication companies. Even before the successful test flight, customers were signed up.
