CAPE CANAVERAL, UNITED STATES — The world鈥檚 most powerful rocket, SpaceX鈥檚 Falcon Heavy, blasted off Tuesday on its highly anticipated maiden test flight, carrying CEO Elon Musk鈥檚 cherry red Tesla Roadster toward an orbit near Mars.

Screams and cheers erupted at mission control in Cape Canaveral, Florida as the massive rocket fired its 27 engines and rumbled into the blue sky over the same NASA launchpad that served as a base for the US missions to the Moon four decades ago.

鈥淭he mission went as well as one could have hoped,鈥 an ecstatic Musk told reporters after the launch, calling it 鈥減robably the most exciting thing I have seen literally ever.鈥

鈥淚 had this image of a giant explosion on the pad with a wheel bouncing down the road with the Tesla logo landing somewhere,鈥 he said. 鈥淔ortunately that is not what happened.鈥

Loaded with Musk鈥檚 red Tesla and a mannequin in a spacesuit, the monster rocket鈥檚 historic test voyage captured the world鈥檚 imagination.

SpaceX鈥檚 webcast showed the Tesla Roadster soaring into space, as David Bowie鈥檚 鈥淪pace Oddity鈥 played in the background — with the words 鈥淒ON鈥橳 PANIC鈥 visible on the dashboard, in an apparent nod to the sci-fi series the 鈥淗itchhiker鈥檚 Guide to the Galaxy.鈥

The Roadster was also outfitted with a data storage unit containing Isaac Asimov鈥檚 science fiction book series, the Foundation Trilogy, and a plaque bearing the names of 6,000 SpaceX employees.

Musk posted a live video showing the 鈥淪tarman鈥 mannequin appearing to cruise, its gloved hand on the wheel, through the darkness of space, with the Earth鈥檚 image reflected on the car鈥檚 glossy red surface.

He tweeted late Tuesday night that the rocket鈥檚 upper stage had made a successful final burn, sending the car and its mannequin passenger out of Earth鈥檚 orbit, into an orbit around the Sun that brings it close to Mars.

After surviving a five-hour journey through the Van Allen Belt — a region of high radiation — the car now embarks on a journey through space that could last a billion years and take it as far as 250 million miles (400 million kilometers) from Earth, the same as a trip around the equator 10,000 times.

鈥淢aybe it will be discovered by some future alien race,鈥 Musk told reporters. 鈥淲hat were these guys doing? Did they worship this car?鈥 he mused.

鈥楪IANT STEP鈥
About two minutes into the flight, the two side boosters peeled away from the center core and made their way back toward Earth for an upright landing.

Both rockets landed side by side in unison on launchpads, live video images showed.

鈥淣ew Olympic sport — Synchronized Landings!鈥 wrote NASA astronaut Randy Bresnik on Twitter.

The third, center booster failed to land on an ocean platform — known as a droneship — as planned.

鈥淚t didn鈥檛 have enough propellant,鈥 Musk said, adding that it plunged into the ocean about 100 meters (yards) away from its landing point.

鈥淎pparently it hit the water at 300 miles an hour and took out two of the engines,鈥 he added.

Experts said the launch would likely catch the eye of the US space agency NASA, which may consider using the Falcon Heavy as a way to fast-track its plans to reach the Moon again for the first time since 1972.

Acting NASA Administrator Robert Lightfoot congratulated SpaceX and called it a 鈥渢remendous accomplishment.鈥

Kennedy Space Center Director Bob Cabana said 鈥渢he successful launch of a new vehicle on its first flight is a significant accomplishment they can be very proud of.鈥

Canadian astronaut Chris Hadfield tweeted: 鈥淲hat we鈥檙e watching is @SpaceX leaving all other rocket companies in the dust. Congrats to everyone there!鈥

FALCON HEAVY SPECS
President Donald Trump also offered his congratulations, tweeting: 鈥淭his achievement, along with @NASA鈥檚 commercial and international partners, continues to show American ingenuity at its best!鈥

Musk replied: 鈥淭hank you on behalf of SpaceX. An exciting future lies ahead!鈥

The Falcon Heavy launched from the same NASA pad that was the base for the Apollo-era Moon missions of the 1960s and 1970s.

It is 鈥渢he most powerful operational rocket in the world by a factor of two,鈥 SpaceX said.

That means it can carry twice the payload of United Launch Alliance鈥檚 Delta IV Heavy, at a far lower cost — about $90 million per launch compared to $350 million for its competitor.

But the Falcon Heavy is not the most powerful rocket ever — just the biggest in operation today.

The Saturn V rocket that propelled astronauts to the Moon could deliver more payload to orbit. The Soviet-era Energia, which flew twice in 1987 and 1988, was also more powerful.

The Falcon Heavy is essentially three smaller, Falcon 9 rockets strapped together, adding up to a total of 27 engines.

The 230-foot (70-meter) tall rocket is designed to carry nearly 141,000 pounds (64 metric tons) into orbit — more than the mass of a fully loaded 737 jetliner.

It was initially intended to restore the possibility of sending humans to the Moon or Mars, but those plans have shifted and now the Falcon Heavy is being considered mainly as a potential equipment carrier to these deep space destinations, Musk said Monday.

Instead, another rocket and spaceship combination being developed by SpaceX, nicknamed BFR — alternately known as 鈥淏ig Fucking Rocket,鈥 or 鈥淏ig Falcon Rocket鈥 — would be the vehicle eventually certified for travelers. — AFP
