Starship, consisting of the Starship upper stage stacked atop its Super Heavy booster, launched around 7.20pm ET from SpaceX’s Starbase facilities. After sending the Starship stage to space, Super Heavy returned for a soft water landing in the Gulf of Mexico roughly 10 minutes after liftoff.

A mission in August ended a streak of testing failures earlier this year as SpaceX pushed to stress-test features for its total reusability. SpaceX, after Monday’s flight, is hoping to start launching a more advanced Starship prototype equipped with features tailored for moon and Mars missions.

“We’ve done everything we can think of to make that next test flight, Flight 11, successful,” SpaceX President Gwynne Shotwell said at a conference in Paris last month. “But, you know, you never know when you’re going to get punched in the face, so we’ll see.”

SpaceX during the mission is aiming to deploy its second cluster of dummy Starlink satellites in space and see the ship reach the Indian Ocean after blazing back through Earth’s atmosphere, where a variety of experimental heat shield tiles on Starship’s exterior will face super-hot plasma.
