Updated: May 21, 2026 — SpaceX's highly anticipated Starship Flight 12 (IFT-12), the debut of the powerful Starship Version 3 (V3) from the brand-new Pad 2, was scrubbed during the countdown.
The countdown proceeded smoothly until approximately T-40 seconds, when SpaceX called a hold. After evaluating the data, the team decided to scrub the launch for the day. No major vehicle issues were reported — the problem originated from ground systems on the new launch pad.
This is a standard occurrence in the early operations of new hardware at Starbase, especially with the upgraded infrastructure for the more powerful Raptor 3 engines on the V3 stack.
The scrub was triggered by an issue with the water deluge system (also referred to as the flame diverter or water suppression system) under the new Orbital Launch Pad 2 (Pad 2) at Starbase, Texas.
The water deluge system floods the pad area with massive volumes of water just before engine ignition. It serves three critical purposes:
SpaceX teams stood down safely to troubleshoot rather than risk the launch. This conservative approach is typical for new vehicle versions and new pads.
Flight 12 marks several major milestones for the Starship program:
| Aspect | Details |
|---|---|
| Vehicle Version | First full Starship V3 stack (Booster 19 + Ship 39) |
| Launch Pad | New Pad 2 at Starbase, Texas |
| Key Upgrades | Raptor 3 engines, larger grid fins, improved heat shield, new fuel transfer systems |
| Objectives | Launch, stage separation, booster boostback & landing burn (no catch attempt), ship in-space maneuvers |
Starship is the most powerful rocket ever built, and SpaceX pushes the boundaries with rapid iteration. Common reasons for Starship launch delays and scrubs include:
SpaceX is expected to attempt another launch in the next available window (likely May 22, 2026). Teams will troubleshoot the deluge system issue overnight.
No. All indications point to a ground systems hold only. The vehicle performed normally during countdown.
It releases hundreds of thousands of gallons of water per minute onto the flame diverter to absorb heat, reduce noise, and protect the pad.
Once Flight 12 is successfully completed, SpaceX plans even more ambitious tests, including booster catches, in-orbit refueling, and higher-energy missions. The iterative development of Starship continues to accelerate.
Starship Flight 12 no go today is just a small step back in a program known for learning fast and flying often.
