SpaceX's Starship V3 rocket, the tallest ever built, is now ready for its debut test flight, scheduled for May 21, 2026. The rocket was stacked at the SpaceX Starbase facility in South Texas, where it underwent a final wet dress rehearsal, successfully fueling both the Super Heavy booster and Ship upper stage. This mission, designated Flight 12, will be a suborbital launch, with plans for the stages to splash down in the Gulf of Mexico and Indian Ocean, respectively. Starship V3 boasts significant upgrades over its predecessors, including docking ports for in-space refueling, essential for future missions beyond low Earth orbit (LEO), such as NASA's Artemis missions. NASA has contracted SpaceX to use Starship as a lunar lander for the Artemis program, with Artemis 3 scheduled for late 2027. This mission will involve the Orion capsule rendezvousing with Starship in LEO. Depending on the results of Flight 12, SpaceX may attempt to recover the Ship upper stage in future flights, further advancing its goal of full reusability.
