SpaceX has sent its enormous
Starship rocket into
Earth’s orbit for the first time on a milestone flight intended to pave the way for future missions to the moon and Mars.The rocket, the largest and most powerful ever built, blasted off from
SpaceX’s Starbase launch facility in
Texas at 7.48am local time (1.48pm BST), marking its 14th test flight and first attempt to circle the planet before falling back to
Earth.Despite an engine failure on ascent that threatened to prevent
Starship from reaching orbit, mission controllers decided it was safe to press ahead with a burn that pushed the ship on to a planned trajectory to take it around the planet.Cheers and applause broke out at
SpaceX after initial suggestions that the orbit attempt might be abandoned were quashed and the decision to go ahead was announced. Moments after the orbit burn,
Daniel Hewitt, an engineer who was narrating a live stream of the launch, declared: “
Starship is in orbit.”
Elon Musk’s company has flown
Starship in its full form since 2023 but previous test flights have only sought to put the rocket into suborbital trajectories, which are simpler and carry fewer risks for the public.The launch from Starbase in

Indian Ocean far from populated areas. The risks are harder to control when rockets are on full orbital paths around the planet.
Starship propelled to an altitude of about 171 miles (275km), with the original aim of completing six loops of
Earth in nearly 10 hours before splashing down in the
Pacific Ocean somewhere west of
Chile. More than an hour into the mission however,
SpaceX said
Starship would come back early, aiming for a landing three hours after launch.

Earth’s orbit - loopMartin Barstow, a professor of astrophysics and space science at the
University of Leicester, said: “This is an important milestone for
SpaceX, with
Starship successfully reaching orbit, and at the first attempt.”The achievement “marks the beginning of the transition from the testing and development phase to becoming a working vehicle able to deliver the large payloads needed to return to the moon,” he added. “Congratulations to the whole
SpaceX team. Having this large launch capability will also be transformational for the whole space industry.”On the launchpad, the rocket stands more than 120 metres tall, with the
Starship upper stage sitting on the “Super Heavy” booster stage. To remain in orbit, the rocket is required to travel at about 28,000km/h (17,400mph).A successful mission will be a relief for
SpaceX and Nasa, who hope to use
Starship to carry astronauts to the moon as part of a new era of lunar expeditions. It will also cheer investors after the company’s high-profile launch on the stock market in June. The company’s stock price rose sharply in the initial public offering before falling back. It has since recovered some of those losses.During the mission,
SpaceX staff will want to see the booster launch, ascend and separate from the
Starship upper stage, then return to an offshore landing point in the Gulf of Mexico. The company does not intend to catch the booster in giant mechanical arms, as it did after a previous test flight in 2024.People watch after the rocket’s successful launch. Photograph:

Earth, but on the last test flight the manoeuvre was ended early because three engines started to clog up with ice. The booster then attempted a landing burn with only eight of 13 planned engines reigniting, leading to a hard landing in the water.On the latest test flight,
Starship deployed next-generation Starlink satellites, which will unfold their antennas, deploy their solar arrays and then raise their orbits using onboard thrusters. Three of the satellites are carrying cameras to capture images of
Starship’s heat shield that will feed into testing for future missions.Musk has set himself the ambitious target of developing fully reusable rockets to speed up mission turnaround times and reduce the costs of future space travel. But several
Starship test flights have ended in failure. In March last year, the rocket exploded soon after launch and scattered debris over the Bahamas. Two months later,
Starship span out of control shortly after separating from its booster. A month after that, the rocket exploded during preparations for a test flight.
