Terraforming is the longest boundary condition: a whole world. Segal's position is disciplined — we deploy the enclosures, shielding, and in-situ material systems that make ground habitable today, and we fund the research for the planetary scale that does not yet exist. Marked honestly, rung by rung.
A planet is the same problem as a building, scaled until the boundary conditions become the atmosphere itself. The algorithm does not change; the enclosure simply grows until, eventually, the enclosure is the sky.
So we work from the bottom up. Pressurized shells today. Linked, climate-managed enclosures next — paraterraforming, where a printed worldhouse holds its own air. Global atmospheric engineering remains research, and we say so. Anyone selling you a terraformed Mars on a product page is selling you the page.
// HABITABILITY LADDER
A printed pressurized structure. Deployable today.
Pre-deployed clusters fed by in-situ material.
A domed, self-holding biome — paraterraforming.
Linked enclosures and managed microclimate.
Global atmosphere and biosphere. Research horizon.
// 01 · Building blocks deployable
Scale the printed pressurized enclosure from a single habitat to a domed biome that holds its own atmosphere. This is the only rung above settlement with deployable building blocks today — and it is built from Segal's core competency.
// 02 · Century-scale
Research into raising atmospheric pressure and warming a thin, cold world — desorbing CO₂ from regolith and polar reserves, and the role and risk of engineered super-greenhouse gases.
// 03 · Multi-decade
Shielding inhabitants from radiation — printed regolith mass shielding at the structure scale today, and research into an artificial magnetosphere (an L1 magnetic dipole) at the planetary scale.
// 04 · Multi-decade
Research into raising surface temperature: orbital solar reflectors and statite mirrors, and albedo modification of polar deposits — with their energy budgets and reversibility studied honestly.
// 05 · Active research
Mapping and mobilizing subsurface ice and bound volatiles — the near-term ISRU that feeds habitats and the long-term inventory that any larger ambition depends on.
// 06 · Century-scale
The biological pathway — pioneer extremophiles, oxygenating cyanobacteria, and regolith-to-soil genesis — pursued under strict planetary-protection and reversibility constraints.
// 07 · Active research
Coupled atmosphere–regolith–energy climate models and digital twins — the instrument that tells us which rungs are reachable and which are fantasy, before any capital moves.
Deployable today: printed pressurized enclosures, in-situ material systems, and regolith mass shielding — the bottom rungs of the ladder, the same competency we run on Earth.
Research horizon: global atmospheric engineering, planetary magnetospheres, planetary-scale thermal systems, and open-environment biology — funded, modeled, and reported, but not sold.
We will move a rung up the ladder only when the rung below it carries weight. That is the whole discipline.
We work with research partners on the upper ladder and with developers on the deployable rungs today. Either conversation is short.
