SpaceX has completed a key Starship V3 launch rehearsal, topping up with propellant as the company prepares its 12th test flight.
A towering Starship V3 stack has rolled into its next phase of testing, and the latest rehearsal is raising expectations for SpaceX’s next high-stakes development milestone.
On May 12. 2026. SpaceX’s newest Starship configuration—paired with a Super Heavy Version 3 (V3) booster—completed a launch rehearsal ahead of an anticipated liftoff that could come as soon as mid-May.. The company has described the upcoming attempt as a pivotal step. not only for the rocket’s engineering roadmap but also for the broader schedule pressure surrounding SpaceX’s planned plans this year.
The rocket currently being readied for its next test flight stands about 124 meters tall.. In its fully reusable configuration. SpaceX says the system is designed to carry up to 150 metric tons of cargo into space—an ambition that underpins the company’s push to make large-scale. frequent launches a practical reality rather than a one-off achievement.
As part of the rehearsal, SpaceX reported that it successfully loaded more than 5,000 metric tons of propellant into the vehicle.. In practical terms. that kind of fueling exercise is a crucial rehearsal checkpoint: it tests the ground systems and countdown procedures needed to move from preparation to a full attempt at launch.
SpaceX says this next effort will be the rocket’s 12th test flight. and it will be the first time the latest version of the vehicle is put through its paces.. While earlier flights have shown promise. the development path for Starship has also included dramatic setbacks. with many prior tests ending in fiery explosions that underscored how much iterative work remains before the system can reliably meet mission goals.
The pressure around Starship is not happening in isolation.. The company is pushing toward going public this year, and that financial and reputational milestone adds urgency to demonstrating progress.. At the same time. SpaceX has repeatedly pointed to Starship as a potential accelerator for its satellite internet business. which relies on building and operating large constellations that have become a major profit driver through Starlink.
Beyond communications, the company is also leaning into the idea of launching and operating artificial intelligence data centers in orbit.. That broader vision depends on Starship’s ability to move payloads efficiently. and on a future where repeated launches are routine rather than exceptional—goals that the next test flight aims to support. even if it is not yet demonstrating everything the system will eventually need to do.
Like previous demonstration flights, the next test is not expected to include Starship attempting to reach low-Earth orbit.. That capability is still considered a crucial requirement ahead of NASA’s planned Artemis III mission. which is expected to involve a chain of steps culminating in lunar landing operations.
Artemis III is scheduled as a milestone mission in which SpaceX’s Starship Human Landing System (or Blue Origin’s Blue Moon rocket. depending on NASA’s selection and mission architecture) would dock with an Orion crew capsule in lunar orbit.. The Artemis III approach is intended as a demonstration step. followed by Artemis IV. with an ultimate aim of ferrying astronauts from lunar orbit to the moon’s surface as soon as 2028.
Even with the hardware development moving forward. some experts have questioned whether Starship will be ready on time for the Artemis timeline.. That skepticism reflects the real-world challenge of turning test-flight momentum into the kind of reliability and readiness large government missions require.
For now. the rehearsal’s most immediate significance is simple: it shows SpaceX is pressing ahead with the next iteration. completing a key fueling and countdown rehearsal milestone as it gears up for a new attempt.. For the space industry watching Starship’s trajectory. the question is less whether SpaceX can keep testing. and more whether the upcoming sequence of demonstrations can shrink the gap between bold technical ambition and the mission-level readiness NASA will demand.
