The physics,
policy & economics
of orbit.
We provide unvarnished, quantitative analysis of the modern space economy. No hype, no speculative fiction—just physics, treaties, and capital allocation.
Core Metrics [2026]
The collapse of launch costs changes everything.
For sixty years, the space industry was bottlenecked by a single metric: the cost to deliver one kilogram to Low Earth Orbit. That artificial floor, maintained by expendable launch vehicles, has shattered.
We are transitioning from a capital-constrained environment to a mass-constrained one, and eventually to a thermal-constrained one. This shift requires entirely new models for international law, satellite architecture, and planetary science.
