Watch SpaceX’s Starship flight 13 launch tonight
NEWS | 16 July 2026
SpaceX is launching the latest version of its Starship megarocket for a test flight that—if all goes to plan—should look a lot like the last one I agree my information will be processed in accordance with the Scientific American and Springer Nature Limited Privacy Policy .

SpaceX is gearing up to launch its Starship megarocket. On Thursday, no earlier than 6:45 P.M. EDT, Elon Musk’s space company will attempt a thirteenth flight test of Starship that will see the rocket put through its paces once again. But as with its last test flight, Starship will not enter Earth orbit; nor will SpaceX try to catch the vehicle’s Super Heavy V3 first stage. Instead, after helping Starship get to space, the technically reusable booster will attempt a controlled descent and landing at splashdown in the Gulf of Mexico. Overall, this flight will look much like the last one, which was largely a success. Riding atop the Super Heavy V3 booster, Starship will lift off from SpaceX’s Starbase complex in Boca Chica, Texas. Its payload includes a cache of Starlink V3 satellites—next-generation spacecraft that are the largest and heaviest yet launched for SpaceX’s relentless expansion of its broadband internet mega constellation. Ultimately, SpaceX wants this flight to iron out the kinks that arose in the last test, chief among them performance issues with the Raptor engines that provide thrust for Starship and its booster.

The flight will also test various upgrades to Starship’s heat shield—one of the most crucial components for the spacecraft, which is designed to be fully reusable. That reusability, SpaceX hopes, will eventually allow the company to phase out its partially reusable workhorse rocket, the Falcon 9, in favor of launching Starships multiple times per day with a mass-to-orbit price tag that competitors can’t beat. The system, in short, is SpaceX’s all-in bet for continuing its global dominance of space launch and satellite communications. If successful, it could catapult the now-publicly traded company and the world alike into a revolutionary new era of spaceflight. SpaceX will have a 90-minute window in which to launch Starship, with a livestream of the rocket beginning some 30 minutes before liftoff on X, and SpaceX's website. Once in space, Starship will attempt to deploy its batch of 20 Starlink satellites. These will seek to connect to the Starlink network via laser-based communications; six of the satellites carry cameras to relay images of Starship’s heat shield to engineers on the ground. All 20 satellites are expected to burn up in Earth’s atmosphere about 20 minutes post-deployment. The whole test from launch to splashdown in the Indian Ocean should last just over an hour. Even without its core goal of full reusability, Starship would be extremely ambitious. It’s SpaceX’s largest vehicle—indeed, the spacecraft is the world’s largest rocket. Fully stacked with its booster, the vehicle is about 407 feet tall and has enough thrust to launch 100 metric tons of cargo into space. Leaving aside SpaceX’s lofty business goals, NASA hopes to use Starship to further U.S. moon base ambitions as part of its Artemis program. If SpaceX can get a NASA-sponsored lunar-lander variant of Starship ready on time, the space agency could use it to send humans to the surface of the moon for the first time in more than 50 years as soon as 2028. A watchdog report published in March made plain that SpaceX wasn’t keeping to schedule, however, and the space agency is also funding development of a Blue Origin lunar lander for the task. The clock is ticking for both companies: NASA’s Artemis III, a crewed mission to test key capabilities for both vehicles in low-Earth orbit, is targeted for launch before the end of next year. But regardless of what happens on Starship’s 13th flight, the vehicle—and the nation—still has a long and perilous ahead, with many more test flights to come before bringing astronauts to the moon, or anywhere else.
