Five years ago today (Feb. 6), SpaceX’s brawny Falcon Heavy rocket left Earth for the first time ever.
That debut mission, which lifted off from NASA’s Kennedy Space Center in Florida, was no ordinary test flight. For starters, it crowned the Falcon Heavy as the most powerful rocket in the world, a title it held until NASA’s Space Launch System flew this past November on the Artemis 1 mission.
The payload was quite memorable as well: The big new rocket sent SpaceX founder and CEO Elon Musk‘s red Tesla Roadster, with a spacesuit-clad mannequin named Starman in the driver’s seat, into orbit around the sun. (Since this was a test flight, SpaceX didn’t put an operational satellite on board. But Musk decided to make the dummy payload an interesting one.)
Starman and his ride are still cruising through deep space, by the way. But they’re headed for a violent end: An orbit-modeling study found that the car will eventually crash into Venus or Earth, probably in the next few tens of millions of years.

The Falcon Heavy consists of three strapped-together first stages of SpaceX’s workhorse Falcon 9 rocket, which are reusable; they’re designed to make vertical landings shortly after liftoff and fly again after some refurbishment. The Heavy’s central booster is topped by an upper stage, which carries the payload.
The Falcon Heavy’s 27 first-stage Merlin engines generate a whopping 5 million pounds of thrust at liftoff, which allows the huge rocket to carry up to 70.3 tons (63.8 metric tons) of payload to low Earth orbit (LEO) on each mission, according to its SpaceX specifications page (opens in new tab). The Falcon 9, by comparison, can deliver about 25.1 tons (22.8 metric tons) to LEO.
The Falcon Heavy now has a total of five flights under its belt, all of them successful. The rocket lofted the Arabsat-6A telecom satellite to orbit in April 2019, then launched a mission for the U.S. Air Force two months later.
The Heavy was then idle for about 40 months, a gap attributable mostly to customer delays in getting their satellites ready. In November 2022, the rocket roared back into action, launching a handful of satellites for the U.S. Space Force. The Heavy flew again on Jan. 15 of this year on another Space Force mission — and it likely won’t be long before we see another liftoff.
“Falcon Heavy has completed five launches to date, and could fly up to five missions this year,” SpaceX said via Twitter today (opens in new tab).
SpaceX is currently gearing up for the debut of another big rocket, by the way, one that will be more powerful than any vehicle that’s ever flown — Starship, which the company is developing to take people and cargo to the moon and Mars.
The latest Starship prototype aced its first-ever fueling test on Jan. 23, and it could launch to orbit for the first time as early as next month if remaining tests go well, Musk said recently.
