SpaceX completes spectacular Starship test flight

SpaceX has successfully launched its biggest ever rocket, named Starship, from Texas after a year of mishaps.

Elon Musk's flagship spacecraft, which has been earmarked for future missions to the moon and Mars, took off just after 6.30pm local time on Tuesday. It launched into orbit and deployed eight dummy satellites before splashing down as planned in the Indian Ocean.

The aim was to test the 403ft-tall ship's new heat shield tiles and satellite deployment abilities, among hundreds of other upgrades from past iterations. Three minutes into the flight and dozens of miles above ground, the rocket's upper half separated as planned from its Super Heavy booster - the 232ft first stage that normally lands back in its launch tower's giant catch-arms.

But this time the booster, which SpaceX said had been fitted with larger and stronger fins for greater stability, targeted the Gulf of Mexico waters to demonstrate an alternate landing strategy. Meanwhile, Starship was launched into space, and deployed its eight dummy Starlink satellites, a key demonstration for a rocket that represents the future of SpaceX's dominant launch business.

An hour into the mission, Starship re-entered Earth's atmosphere over the Indian Ocean, putting a variety of hexagonal heat shield tiles to the test as it blazed at supersonic speed.

But SpaceX has been trying to create an exterior shield that requires little to no refurbishment after each use. The crewless demo launch came after back-to-back tests in January and March ended just minutes after lift-off, raining wreckage into the ocean, before the most recent test in May ended when the spacecraft tumbling out of control and breaking apart.

That all came after the first Starship exploded minutes into its inaugural test flight in 2023. NASA has ordered two Starships to land astronauts on the moon later this decade, while Mr Musk has ambitious plans to send humans to space in the next few years..
