SpaceX is preparing for Starship’s twelfth integrated flight test (IFT-12), the next major milestone in its ambitious push toward fully reusable orbital launch capabilities. As of Tuesday, May 20, the company has updated the target launch date to Thursday, May 21, 2026, with the launch window opening at 5:30 p.m. CDT (22:30 UTC) from the new Pad 2 at Starbase in Boca Chica, Texas. The two-hour window extends until approximately 7:00 p.m. CDT (00:00 UTC on May 22).
This marks a 24-hour delay from the earlier target of May 20, which itself followed previous slips from mid-May dates. SpaceX has confirmed the May 21 window on its launches page and dedicated Starship Flight 12 page.
Mission Details and What to Expect
- Vehicle configuration: This will be the debut flight of SpaceX’s next-generation Starship and Super Heavy vehicles, powered by the next evolution of the Raptor engine and featuring structural improvements. The booster (B19) and ship (S39) will fly from the newly constructed second launch pad at Starbase (OLP-2 / Pad 2).
- Flight profile: Suborbital test flight. The Super Heavy booster will not attempt a tower catch and is expected to be expended in the Gulf of Mexico. The Starship upper stage will follow a suborbital trajectory, deploying 20 Starlink simulator satellites (including two modified units designed to capture and relay heat-shield imagery during reentry).
- Significance: IFT-12 represents the first launch from Starbase’s second pad and the introduction of the next-generation Starship/Super Heavy stack. It continues the rapid iteration that has defined the program, building on the success of prior flights while testing new hardware under real flight conditions.
Why the Schedule Matters
Starship flight tests remain highly dynamic. The May 20 target was adjusted within days, a common occurrence as teams work through final ground testing, weather, and regulatory clearances. As of May 20, Starship and Super Heavy have been rolled out and stacked on the pad for final preparations, but SpaceX typically provides a final “go/no-go” poll closer to liftoff and may issue last-minute adjustments via its website or X account.
For viewers in different time zones:
- Eastern Daylight Time (EDT): 6:30 p.m. – 8:00 p.m. (May 21)
- UTC: 22:30 – 00:00 (May 22)
- Pacific Daylight Time (PDT): 3:30 p.m. – 5:00 p.m. (May 21)
Live coverage is expected on SpaceX’s YouTube channel and X account, with the webcast usually beginning about an hour before the window opens.
Looking Ahead
With IFT-12 now one day away, attention is already turning to IFT-13 (currently targeted for later in 2026) and the long-term goal of dozens of Starship flights per year. The program’s pace continues to accelerate as SpaceX expands launch infrastructure and iterates on the next-generation design.
Schedules can shift quickly in the Starship program – watch @SpaceX and @elonmusk on X for real-time updates, or check the official launches page for the latest confirmation. As of May 20, 2026, the countdown is on for Thursday evening in Texas.
