The planet

Mars

Crust, ice, sulfur, dunes, organics. The papers that treat the planet as it is — before the city, before the stack that has to fly.

Mars research

On this desk

Dichotomy, ice, native sulfur, Kaiser Crater dunes, Gale organics, power, dust. New Mars papers land here. Starship hardware and TeraFab stay on their own tabs.

Metallic Waves on Ancient Mars

They look like metal. They are sand.

Mars’s Subsurface Sanctuary

Curiosity found the largest organic molecules yet confirmed on Mars inside a 3.7-billion-year-old lakebed. Reconstructing what radiation destroyed may matter more than what survived.

The Imperative of Making Life Multiplanetary

Preserving and extending the light of consciousness — a tiny candle in a vast darkness that could easily go out.

The Rock That Broke Open Mars

Curiosity’s wheel fractured an ordinary stone in Gediz Vallis and exposed yellow crystals no mission had confirmed on Mars: native elemental sulfur.

The Last Meters of Dust

Starship can cross the vacuum. Return propellant cannot. The bottleneck is not interplanetary distance — it is meters of abrasive, buried ice.

The Martian Dichotomy

A 4-billion-year-old scar that decided where the last oases could live — and why the carbon cycle died.

The Ice Is Not Vanishing

Twenty to thirty meters of global equivalent water. The loss rates are geological. The problem is extraction, not disappearance.

Powering Mars

3.6 megawatts to keep a crew alive and fill two Starships. Solar is a dust-storm hostage. Fission is the baseload that makes return possible.

Was Early Mars Green?

Ninety to ninety-nine percent chance it was livable, at least in pulses. Curiosity and Perseverance keep handing over the receipts.

A Single Planet Is a Failure Mode

Making life multiplanetary is not optional. It is the minimum requirement to turn a brief accident into a durable feature of the cosmos.

Why Mars, Not the Moon

The Moon cannot hold an atmosphere. Mars starts with CO2, ice, a 24.6-hour day, and 97% of Earth’s land mass. Self-sustaining civilization has a preferred planet.
