SpaceX's Starship spacecraft returned from its longest-yet flight in orbit on Saturday to the tower it was launched from on Friday.
The spaceship descended and smoothly slipped between the mechanical "chopstick arms" above Launch Pad 2 in the US state of Texas. It was the first key recovery of the rocket system's centerpiece vessel in the company's decadelong effort to develop a fully reusable rocket.
It was the 15th test flight of the world's biggest and most powerful rocket system. SpaceX had intended to also capture the Super Heavy booster that launched the Starship, but the lower stage recovery was aborted and it exploded over the Gulf of Mexico shortly after launch on Friday.
The successful return of the craft's upper stage after orbiting Earth 14 times for over 22 hours, during which it deployed 26 Starlink satellites, marked a key milestone in the multibillion-dollar development of Starship, which billionaire Elon Musk sees as key to SpaceX's satellite business and ambitions to put humans on the moon and eventually Mars.
NASA welcomed the news. The US space agency is paying billions of dollars for Starship to land Artemis astronauts on the moon later this decade and help build a permanent lunar base.
