## The Gap Between Announcement and Orbit

SpaceX has said "humans to Mars by the late 2020s" since 2016. It's 2026. Starship has completed its full test flight sequence — orbital velocity, controlled reentry, booster catch. That's genuinely impressive. But let's be honest about what it doesn't mean yet.

## What's Been Achieved

- **Starship IFT-8**: Ship survived reentry within target zone. Booster caught by mechazilla arms for second time.
- **Raptor reliability**: 33 engines firing simultaneously with zero failures on the last flight.

## What Remains Unsolved

**Radiation**: The Mars transit delivers ~300 mSv per crew member per trip — equivalent to 60 chest CT scans each way. No credible shielding solution yet.

**ISRU**: Making fuel on Mars from CO₂ and water ice. MOXIE proved oxygen production works; scale-up is orders of magnitude harder.

**Mars entry**: Starship's aerodynamic profile for Mars entry hasn't been tested even in simulation at full fidelity.

## Realistic Timeline

| Milestone | Optimistic | Realistic |
|-----------|-----------|---------|
| Uncrewed Mars landing | 2028 | 2030 |
| Crewed transit test | 2031 | 2034 |

The technology is on track. The biology isn't.
