SpaceX’s Starship has blasted off from Texas on a fourth test flight for the rocket that Nasa and Elon Musk are counting on to get humanity to the moon and Mars.
The world’s largest and most powerful rocket — almost 400ft tall — was empty as it soared above the Gulf of Mexico and headed east.
The spacecraft on top is aiming for a half-lap around the planet with a splashdown in the Indian Ocean, after it ditches the first-stage booster in the Gulf.
This time, SpaceX is looking to avoid explosions by controlling the descents. SpaceX came close in March, but lost contact with the spacecraft as it flew out of space and blew up short of its goal.

The booster also ruptured in flight, a quarter of a mile above the Gulf.
Last year’s two test flights ended in explosions shortly after blasting off from the southern tip of Texas near the Mexican border. The first one left a crater in the pad at Boca Chica Beach and threw debris for thousands of feet.
SpaceX upgraded the software and made some rocket-flyback changes to improve the odds.
The Federal Aviation Administration signed off on Tuesday on this fourth demo, saying all safety requirements had been met.
Starship is designed to be fully reusable, which is why SpaceX wants to control the booster’s entry into the Gulf and the spacecraft’s descent into the Indian Ocean — it is intended as practice for planned future landings. Nothing will be recovered from Thursday’s flight.
Nasa has ordered a pair of Starships for two moon-landing missions by astronauts later this decade. Each moon crew will rely on Nasa’s own rocket and capsule to leave Earth, but meet Starship in lunar orbit for the ride down to the surface.
SpaceX is already selling tourist trips around the moon. The first private lunar customer, a Japanese tycoon, pulled out of the trip with his entourage last week, citing the oft-delayed schedule.
SpaceX’s founder and chief executive has grander plans: Mr Musk envisions fleets of Starships launching people and the infrastructure necessary to build a city on Mars.
