SpaceX has postponed the launch of its third-generation Starship rocket, designated for the Flight 12 mission, which was scheduled for May 21, 2026. The decision to scrub the launch was made after the countdown experienced multiple holds at T-minus 40 seconds, ultimately halting at approximately 6:40 p.m. CDT (7:40 p.m. EDT / 2340 UTC).
Elon Musk, founder and CEO of SpaceX, reported on social media that the hydraulic pin securing the tower arm did not retract, leading to the cancellation. He indicated that if repairs could be completed overnight, a new launch attempt could occur the following day at 5:30 p.m. CDT.
Mission Parameters and Objectives
The Starship rocket stands at 407 feet (124 meters) tall and is designed for a suborbital mission. During the Flight 12 mission, the Super Heavy booster (Booster 19) is expected to splash down in the Gulf of Mexico, while the Starship upper stage (Ship 39) will meet its end in the Indian Ocean. The launch window for the next attempt opens at 5:30 p.m. CDT (6:30 p.m. EDT / 2230 UTC) on May 22, provided that repairs are successful.
Development and Financial Context
Following five successful flights of Starship Version 2 in 2025, SpaceX has moved to this next iteration after extensive testing, including two explosive incidents that destroyed a Super Heavy booster and a Starship. In a recent filing with the U.S. Securities and Exchange Commission, SpaceX disclosed that it has invested over $15 billion in Starship development. The company reported a loss of $657 million from operations in 2025, alongside a Segment Adjusted EBITDA of $653 million, which includes a $3 billion investment in research and development for the next-generation launch vehicle.
Flight 12’s Payload and Objectives
For this test flight, Flight 12 will deploy 20 Starlink simulator satellites on a suborbital trajectory approximately 10 minutes into the flight. Additionally, two modified Starlink satellites will be released to scan the Starship’s heat shield and transmit imagery back to operators, aiding in the assessment of heat shield readiness for future missions. Several tiles on the Starship have been painted white to simulate missing tiles, serving as imaging targets during this test.
Moreover, SpaceX plans to relight one of the Raptor engines on Ship 39 during a coast period, nearly 39 minutes into the mission. This engine demonstration will provide valuable data for future deorbiting burns as SpaceX prepares for orbital launches. Ship 39 is expected to target a controlled splashdown in the Indian Ocean over an hour after liftoff from Texas.
