SpaceX’s SN10 Starship prototype exploded Wednesday after a successful flight and touchdown.
The prototype soared more than 6 miles (10 kilometers) into the air, turned horizontal to control descent, then flipped back vertical for the landing. Minutes later the rocket exploded.
SpaceX has not said what caused the explosion.
Chief Executive Elon Musk tweeted, “Starship 10 landed in one piece! RIP SN10, honorable discharge.”
He added: “SpaceX team is doing great work! One day, the true measure of success will be that Starship flights are commonplace.”
SpaceX’s two previous prototypes, SN9 and SN8, experienced failures just before landing.
The Starship is intended to be SpaceX’s vehicle to Mars.
