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 Monday, May 18, the company has updated the target launch date to Wednesday, May 20, 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 21).
This marks a slight delay from the earlier target of May 19, which itself followed previous slips from mid-May dates. SpaceX has not yet issued a new official update confirming the May 20 window beyond its launches page, but multiple tracking sources now list it as the current NET (no earlier than) date.
Mission Details and What to Expect
- Vehicle configuration: This will be the debut flight of SpaceX’s Block 3 (Version 3) Starship and Super Heavy hardware, featuring upgraded Raptor engines and 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 19 target announced by SpaceX on May 12 was adjusted within days, a common occurrence as teams work through final ground testing, weather, and regulatory clearances. As of May 18, no static-fire or rollout updates have altered the May 20 window, 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.
- UTC: 22:30 – 00:00 (May 21)
- Pacific Daylight Time (PDT): 3:30 p.m. – 5:00 p.m. (May 20)
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 just days 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 Block 3 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 18, 2026, the countdown is on for Wednesday evening in Texas.
