SpaceX delays Starship flight 12 to early April as it prepares the upgraded Version 3 for future lunar missions.
SpaceX has announced another delay for the highly anticipated flight-12 test of its Starship rocket, pushing the launch to early April. The company, led by CEO Elon Musk, is working on finalizing updates to the rocket's design, which is expected to debut as the upgraded Version 3 model.
In a social media post on March 7, Musk confirmed the delay, stating that the launch would now occur in "four weeks." This marks a shift from the previous timeline, which had anticipated the launch taking place in early March. Neither Musk nor SpaceX has publicly disclosed the specific reasons for the delay.
A redesigned Starship enters the spotlight
The upcoming flight will feature the first test of Starship Version 3, the latest iteration of what is considered the largest and most powerful rocket ever built. Standing at over 400 feet tall, the redesigned Starship is touted by Musk to be "slightly larger" and "considerably more powerful" than its predecessor, Version 2.
In its final planned configuration, the Starship system will consist of two parts: the Super Heavy booster for initial thrust and the upper-stage spacecraft, also called Starship, which will carry crew and cargo. SpaceX aims for the rocket to be fully reusable and capable of supporting ambitious missions, including lunar landings under NASA's Artemis program and, eventually, human expeditions to Mars.
Version 3 introduces new capabilities, including the ability to refuel its upper stage midflight. This involves two Starships docking in orbit to transfer hundreds of tons of super-cooled propellant, a critical milestone that is necessary for long-distance missions to destinations such as Mars.
Preparations underway in Texas
SpaceX has continued testing the hardware for the flight-12 mission at its Starbase facility in South Texas. On March 7, the company confirmed completing a "cryoproof" test of the designated upper-stage vehicle, known as Ship 39. This test demonstrated the vehicle's propellant loading and structural strength, marking an important step toward final launch readiness.
Additionally, SpaceX reported on March 9 that the Super Heavy booster assigned to the mission has passed preflight checks and is ready for further testing. These milestones indicate steady progress as SpaceX prepares for the rocket's debut.
NASA pressures SpaceX ahead of Artemis 4

The delay comes as SpaceX is under mounting pressure from NASA to ensure Starship is ready for future lunar missions. The space agency has selected Starship as the lander for several Artemis missions, including Artemis 4, scheduled for 2028. Starship’s ability to handle lunar surface operations and long-duration space travel is central to NASA's plans to return humans to the moon.
Meanwhile, SpaceX faces competition from Blue Origin, another private aerospace company tasked with developing lunar landers for Artemis. Both companies are racing to meet NASA's timelines for the ambitious program.
A year of challenges and successes for Starship
Although 2025 saw significant challenges for Starship, including three failed test flights, SpaceX ended the year strong with two successful launches in August and October. The October mission marked the final use of Version 2, making way for the debut of Version 3 in 2026.
When Starship Version 3 finally takes flight, it will be a pivotal test not just for the upgraded rocket but for SpaceX's broader ambitions. With plans to launch from both Texas and Florida later this year, the company is laying the groundwork for Starship’s role in lunar exploration, while keeping its long-term sights on Mars.
As of now, all eyes are on April, when SpaceX hopes to launch Starship flight 12 and demonstrate the capabilities of its next-generation rocket. Whether it succeeds in reaching orbit or beyond, this mission marks an important step forward in the evolution of the Starship program.
