Unlike on Earth, where atmospheric drag makes electromagnetic launchers (mass drivers) impractical, the Moon's vacuum environment makes them highly efficient. This technology could turn the Moon into a "train station" for the solar system, launching raw materials and goods to Mars at a fraction of the energy cost.

Tom Mueller argues that moving data centers to space is an inevitable solution to AI's crushing energy demand on Earth. With compute power needs growing over 15% annually, space offers unlimited solar power as an input, with data as the only output beamed back via laser.

Tom Mueller believes the Moon is more important than Mars in the near term, primarily as a source of critical resources. He highlights a potential terrestrial copper shortage, driven by data center demand, as a key economic driver for establishing a lunar mining presence.

The agency's purpose is to tackle near-impossible challenges where no viable business case or revenue model exists, such as developing nuclear propulsion for Mars. Once a breakthrough is made, the technology can be handed off to the private sector for commercialization, product improvement, and cost reduction.

Fusion reactors on Earth require massive, expensive vacuum chambers. Zephyr Fusion's core insight is to build its reactor in space, leveraging the perfect vacuum that already exists for free. This first-principles approach sidesteps a primary engineering and cost hurdle, potentially making fusion a more commercially viable energy source.

CEO Tom Mueller argues that while the Moon is important, some near-Earth asteroids are easier targets for resource extraction. The Moon's gravity well requires significant fuel for landing and takeoff, whereas asteroids have almost no gravity, making resource return missions far more efficient from a propulsion standpoint.

Despite nuclear power's poor public image based on fission, significant advances in fusion technology are positioning it as a potential solution for clean, abundant energy. We may look back on 2026 as the year this shift became viable.

Radiant founder Doug Bernauer was tasked with powering a Mars colony at SpaceX. After struggling with solar's limitations, Elon Musk suggested nuclear. This R&D directly led him to found Radiant, applying space-grade power concepts to terrestrial energy problems.

After helping solve Earth-to-orbit launch, Mueller founded Impulse Space to focus on the next major opportunity: moving payloads around in space. He views launch as a 'solved' problem and in-space transportation as the next critical layer of infrastructure.
