SPCX — NASA Wind-Tunnel Tests Super Heavy V3 Booster · Starship HLS Artemis Missions

Test Details

Today from DogeDesigner on NASA observation:

- **Subject**: NASA (National Aeronautics and Space Administration)

- **Target**: SpaceX Super Heavy Version 3 booster

- **Test location**: NASA Ames Research Center

- **Model scale**: 1.2% (scale-down model of real vehicle)

- **Test speeds**: Mach 0.2 - Mach 3.5 (subsonic ~ supersonic)

- **Measured**: Aerodynamic forces · buffeting · vibrations

- **Purpose**: Improve re-entry flight guidance / structural-load simulations

- **Final application**: Starship HLS Artemis missions

Why This Test Matters

1. **Super Heavy V3 validation**: V3 is latest iteration · booster of large rocket to replace Falcon 9 · safety/performance validation is precondition for commercialization

2. **Artemis HLS mission prep**: Starship HLS (Human Landing System) is NASA's crewed Moon-landing program. Super Heavy V3 is launch booster for this mission

3. **NASA-SPCX partnership deepens**: NASA resources (Ames wind tunnel) used by SPCX · substance of government-private partnership

4. **Mach 0.2-3.5 wide coverage**: Wide range from subsonic to supersonic = full flight profile validation

SPCX Role in Artemis Program

Artemis (NASA crewed Moon return/settlement program):

- Starship HLS: Lunar lander (SPCX responsible)

- Super Heavy: Launch booster (SPCX responsible)

- Falcon Heavy / Falcon 9: Other payload launches (SPCX responsible)

- Dragon: Crew/cargo transport (SPCX responsible)

- Orion: Crew capsule (Lockheed Martin responsible)

- SLS: Launch rocket (Boeing responsible, delay/cost issues)

SPCX responsible for Artemis multi-axis. Today's Super Heavy V3 test is progress on this axis.

Combined With Recent SPCX·NASA Flow

- **7/27**: NASA Admin Sean Duffy bull statement

- **7/28**: Starship Flight 13 heat-shield stress test success

- **7/29**: Starship Flight 13 landing success (soft splash)

- **7/31**: US Space Force $1.8B contract

- **Today**: NASA Super Heavy V3 wind-tunnel test · Colossus BlackRock 1.2 GW · Musk 99.99% compute to space

SPCX (a) government contract expansion, (b) technical validation progress, (c) orbital DC frame strengthening on 3-fold axis expansion.

Meaning of Mach 0.2-3.5

- **Mach 0.2**: Early launch (subsonic)

- **Near Mach 1**: Sound-speed breakthrough (transonic · hardest zone)

- **Mach 3.5**: Post-atmosphere ascent (supersonic)

Wide-range speed testing = full flight profile safety/performance confirmation.

Counter-view

(1) Wind-tunnel test is one of many validation stages · actual launch validation separate, (2) 1.2% scale model can't perfectly match real vehicle, (3) Artemis HLS mission real Moon landing timing still uncertain.

Implications

1. **NASA-SPCX partnership substance**: Uses government resources · softens political/regulatory risk

2. **Super Heavy V3 real prep**: Physical basis for all-in Starship decision expanded

3. **Artemis follow-on mission support**: Real progress on crewed Moon landing

4. **SPCX price reversal material**: Substantive progress continues despite today's record-low close
