SpaceX launched its sixth Starship rocket Tuesday, proving for the first time that the stainless steel ship can maneuver in space and paving the way for an even larger, upgraded vehicle slated to debut on the next test flight.

The only hiccup was an abortive attempt to catch the rocket's Super Heavy booster back at the launch site in South Texas, something SpaceX achieved on the previous flight on October 13. The Starship upper stage flew halfway around the world, reaching an altitude of 118 miles (190 kilometers) before plunging through the atmosphere for a pinpoint slow-speed splashdown in the Indian Ocean.

The sixth flight of the world's largest launcher—standing 398 feet (121.3 meters) tall—began with a lumbering liftoff from SpaceX's Starbase facility near the US-Mexico border at 4 pm CST (22:00 UTC) Tuesday. The rocket headed east over the Gulf of Mexico, propelled by 33 Raptor engines clustered on the bottom of its Super Heavy first stage.

BOCA CHICA BEACH, Texas—I've taken some time to process what happened on the mudflats of South Texas a little more than a week ago and relived the scene in my mind countless times.

With each replay, it's still as astonishing as it was when I saw it on October 13, standing on an elevated platform less than 4 miles away. It was surreal watching SpaceX's enormous 20-story-tall Super Heavy rocket booster plummeting through the sky before being caught back at its launch pad by giant mechanical arms.

This is the way, according to SpaceX, to enable a future where it's possible to rapidly reuse rockets, not too different from the way airlines turn around their planes between flights. This is required for SpaceX to accomplish the company's mission, set out by Elon Musk two decades ago, of building a settlement on Mars.

BOCA CHICA BEACH, Texas—SpaceX accomplished a groundbreaking engineering feat Sunday when it launched the fifth test flight of its gigantic Starship rocket and then caught the booster back at the launch pad in Texas with mechanical arms seven minutes later.

This achievement is the first of its kind, and it's crucial for SpaceX's vision of rapidly reusing the Starship rocket, enabling human expeditions to the Moon and Mars, routine access to space for mind-bogglingly massive payloads, and novel capabilities that no other company—or country—seems close to attaining.

The test flight began with a thundering liftoff of the 398-foot-tall (121.3-meter) Starship rocket at 7:25 am CDT (12:25 UTC) from SpaceX's Starbase launch site in South Texas, a few miles north of the US-Mexico border. The rocket's Super Heavy booster stage fired 33 Raptor engines, generating nearly 17 million pounds of thrust and gulping 20 tons of methane and liquid oxygen propellants per second at full throttle.

It's unclear yet how long SpaceX's workhorse Falcon 9 rocket will remain grounded as engineers investigate a rare launch failure last week, but the next test flight of the company's next-generation Starship vehicle appears to be on track for liftoff next month.

On Monday, SpaceX test-fired the 33 Raptor engines on the Starship rocket's Super Heavy booster at the company's Starbase facility in South Texas. The methane-fueled engines fired for about eight seconds, long enough for SpaceX engineers to verify all systems functioned normally. At full power, the 33 engines generated nearly 17 million pounds of thrust, twice the power output of NASA's iconic Saturn V Moon rocket.

SpaceX confirmed the static fire test reached its full duration, and teams drained methane and liquid oxygen from the rocket, known as Booster 12 in the company's inventory of ships and boosters. The upper stage for the next Starship test flight, known as Ship 30, completed the static fire of its six Raptor engines in May.
