SpaceX launched its Starship Falcon 9 rocket from its Starbase facility in southern Texas, on Thursday, the company’s latest attempt for a historic orbital test flight.

The Starship took off from its launchpad in Boca Chica at about 9:25 a.m. ET, clearing several critical hurdles along its hourlong journey before burning up upon reentry above the Indian Ocean.

“Starship reached orbital velocity!” SpaceX founder Elon Musk wrote on X at 9:40 a.m. ET. “Congratulations @SpaceX team!!”

The launch was initially scheduled for 8:30 a.m. ET, but was pushed back to give boats time to clear the keep out area.

Starship is the world’s biggest rocket, measuring 30 feet wide and standing nearly 400 feet tall — or about 90 feet taller than the Statue of Liberty. It weighs more than 11 million pounds when fueled. SpaceX designed the rocket with the goal of bringing people to Mars and the moon.

“While it’s not happening in a lab or on a test stand, this is absolutely a test,” SpaceX said in a post on X. “What we’re doing today will provide invaluable data to continue rapid development of Starship.”

This was the third launch attempt for SpaceX’s Starship, following two previous unsuccessful attempts. The last one — in November — ended in an explosion over the Gulf of Mexico just minutes into its test flight.

The rocket reached space following liftoff before communication suddenly was lost, SpaceX officials said, later confirming it had exploded over the Gulf.

“At company headquarters in Hawthorne, Calif., employees cheered as Starship soared at daybreak,” the Associated Press reported at the time. “The room grew quiet once it was clear that the spaceship had been destroyed.”
