Mars from high orbit: a rust-red globe against black space, Valles Marineris cutting a dark scar across the equator.

Imagine Mars

First-principles notes on crust, ice, power, Starship, and the silicon backbone that makes return possible.

Starship S40 in orbit over a sunlit Earth: heatshield tiles and stainless flank, the ship stretching toward the curved horizon.

Starship

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.

The First Interplanetary Flyby

Two years outside the Earth-Moon system, a flyby of the Red Planet, and a return to Earth. Not a landing. A named commander is not a closed architecture.

A dense star field over a dark horizon — the view this desk argues we have to reach.

Manifesto

A single planet is an unacceptable failure mode

Consciousness trapped on one world is a brief accident. Ice, power, Starship, and the TeraFab files are the loads that have to close.

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.
