Mars from high orbit

Imagine Mars.Build it.

First-principles notes on crust, ice, power, Starship, and the silicon backbone that makes return possible. Lacey Presley’s public desk — essays, native Mars films, and dispatches from X.

Starship on a Martian field

Vehicle · SpaceX published figures · August 2026

Starship is the stack that has to fly.

Fully reusable. Methane and oxygen. Tankers in LEO, then Mars. The published vehicle is 124 meters of stainless and 33 Raptor 3s. This desk keeps the surface loads that vehicle still has to close.

Soft splashdown

Starship / Super Heavy V3 · second V3 flight. 20 Starlink V3 satellites — first Starship deployment of the class. Ship guided on four flaps to the Indian Ocean, three-engine landing burn, intact heatshield seen for the first time.

Manifesto

A single planet is an unacceptable failure mode.

Read the paper

Consciousness trapped on one world is a brief accident — a tiny candle in a vast darkness that could easily go out. The work is to keep that flame alive: ice that can be mined, power that does not die in a dust storm, a vehicle that is itself the escape system, and compute that can live in orbit. The TeraFab files live with the rest of the research.

This site is the public desk for that work: the Martian dichotomy as carbon tomb, the 20–30 meter ice inventory, TeraFab as logistics, and the 2026 cryogenic-refueling gate. Sourced from @LaceyPresley and the MarsForge community. The archive lives here so the argument can be read without the scroll.

The Rock That Broke Open Mars

A rover wheel fractured an ordinary stone in Gediz Vallis. Inside: yellow crystals no mission had confirmed on Mars — native elemental sulfur.
