Update for 3 pm ET: SpaceX CEO Elon Musk says the second Starship launch is postponed to no earlier than Saturday, Nov. 18 to replace a grid fin actuator on the launch stack, according to an update Musk posted on X, formerly Twitter.

It's been nearly seven months since SpaceX's first Starship megarocket exploded in a brilliant fireball over South Texas in a failed launch test, but the company is ready to try again. If you're hoping to watch SpaceX's second Starship test flight, you'll need to know when to tune in, and for that, we've got you covered. 

SpaceX's second Starship and Super Heavy booster test flight is currently scheduled to launch from the company's Starbase site near Boca Chica, Texas no earlier than Saturday, Nov. 18, at 8 a.m. EST (1300 GMT). It will be 7 a.m. local time at liftoff time. The launch was originally set for Nov. 17, but SpaceX delayed it by 24 hours to replace a grid fin actuator on the launch stack.

Standing 395 feet tall (120 meters) tall, Starship is the world's tallest and most powerful rocket, and it's designed to be fully reusable for SpaceX missions to deep space. NASA has picked Starship to land its Artemis 3 astronauts on the moon in 2025. But first, SpaceX has to prove Starship is ready for orbital flight, which is where this test comes in. It remains to be seen if SpaceX will target the 8 a.m. EST start time or aim for sometime within its launch window. Here's what we know about what time the mission will fly.
