Starship, the world's most powerful rocket, flew further and faster than ever before during its third test flight on Thursday, although it was eventually lost as it re-entered the atmosphere over the Indian Ocean, SpaceX said.

Lift-off from the company's Starbase in southeast Texas came around 8.25am local time (1325 GMT) and was carried live on a webcast that was eventually watched by more than 3.5 million people on social media platform X.

The sleek mega rocket is vital to Nasa's plans for landing astronauts on the Moon later this decade — and Elon Musk's hopes of eventually colonising Mars.

Two prior attempts have ended in spectacular explosions, although that's not necessarily a bad thing: The company has adopted a rapid trial-and-error approach in order to accelerate development, and the strategy has brought success in the past.

When the two stages of Starship are combined, the rocket stands 397 feet (121 metres) tall -- beating the Statue of Liberty by a comfortable 90 feet.

Its Super Heavy Booster produces 16.7 million pounds (74.3 Meganewtons) of thrust, almost double that of the world's second most powerful rocket, Nasa's Space Launch System (SLS) -- though the latter is now certified, while Starship is still a prototype.

Starship's third launch test in its fully stacked configuration was its most ambitious yet and the company said it was able to meet many of its objectives.

These included opening and closing Starship's payload door to test its ability to deliver satellites and other cargo into space.

High definition footage from an onboard camera showed Starship firing its engines in space, with the curve of the Earth visible in the background. It hit a top speed of more than 26,000 kilometres per hour and achieved an altitude of more than 200 kilometres.

Starship flew halfway around the globe, then began its descent phase over the Indian Ocean, with engineers cheering as the craft's heat shield composed of 18,000 hexagonal tiles glowed red hot.

But ground control stopped receiving signals when it was 65 kilometres above sea level, and announcers declared the vessel "lost" before it could achieve its final goal of splashing down in the water.

"Starship will make life multiplanetary," Musk, the company's billionaire founder, posted on X afterward, emphasising the progress made in this test flight.

The first so-called "integrated" test came in April 2023. SpaceX was forced to blow up Starship within a few minutes of launch, because the two stages failed to separate.

The rocket disintegrated into a ball of fire and crashed into the Gulf of Mexico, sending a dust cloud over a town several miles (kilometers) away.

The second test in November 2023 fared slightly better: The booster separated from the spaceship, but both then exploded over the ocean, in what the company euphemistically called a "rapid unscheduled disassembly."

SpaceX's strategy of carrying out tests in the real world rather than in labs has paid off in the past.

Not only does SpaceX need to prove it can launch, fly and land Starship safely -- it must eventually also show it can send multiple "Starship tankers" into orbit to refuel a main Starship for its onward journey to the Moon.
