Quiet Breakout: A State School in Orlando Quietly Won the Lunar Mining Patent Race

The most important lunar mining technology in the United States is sitting in a warehouse next to a public university in Florida. Not a SpaceX subsidiary. Not a Lockheed unit. A research foundation attached to a state school in Orlando, holding more US patents on extracting industrial-scale water from the surface of the Moon than every named aerospace company combined.

Sift the US patent record from 2023 to today. Filter for grants whose titles mention lunar surfaces, regolith, or cislunar operations. You get 24 patents. The University of Central Florida Research Foundation holds five of them. Blue Origin Manufacturing holds one. Colorado School of Mines holds one. Northeastern, Northwestern, Florida International University, Mitsubishi Electric, Ball Aerospace, Oshkosh Corporation, Sidus Space, and the Chinese Academy of Sciences each hold one. NASA, by name, holds two.

Five times Blue Origin. Two-and-a-half times the federal agency that sent humans to the Moon.

Before 2020, the US Patent and Trademark Office had granted exactly zero patents on systems for extracting water from lunar regolith. Zero. The category did not exist. UCF invented it.

How a 5,000-square-foot lab in Orlando ate the lunar economy

The principal inventor is named on every UCF lunar patent: Philip Metzger. He spent 30 years at NASA’s Kennedy Space Center, where he co-founded a skunk-works lab called Swamp Works in 2012 and led $5.4 million in space-mining research before retiring early and walking across the marsh to UCF’s Florida Space Institute. The International Astronomical Union has since named asteroid 36329 after him. He is a planetary physicist with an asteroid and four continuation patents on the same machine.

That machine is called Aqua Factorem. The 2025 grant (US 12,305,514, issued May 20) describes it like a soft-rock processing plant scaled for vacuum. A bucket digs a permanently-shadowed lunar crater floor. A gravel separator drops anything coarser than ice grain. The remainder, an ice-regolith powder of 10–100 micron particles, gets fed into a pneumatic separator that splits it by aerodynamic drag into streams of lithic fragments and ice. Each stream then passes a magnetic separator, which yanks out paramagnetic basalt, and a tribocharger, which uses friction-induced static charge to accelerate ice particles 100 to 10,000 times harder than rock fragments of the same size. The discharged slag is up to 80 percent of the input mass.

The whole thing is engineered for one number. The conventional way to liberate lunar ice is to bake the regolith with microwaves or steam. Metzger’s NIAC report puts the power requirement for that approach at 800 kilowatts. Aqua Factorem’s mechanical approach uses less than 100 watts. That is an 8,000x reduction in the only resource you cannot ship from Earth.

A second UCF patent, granted August 12, 2025 (US 12,384,730), takes the basalt that Aqua Factorem rejects as trash and turns it into bricks. The trick is metallurgy. After magnetic sorting, UCF’s machine compacts a thin top layer of magnetic lunar dust above a thicker sublayer of non-magnetic dust. A microwave generator at swept wavelengths heats the magnetic top layer to 1,200–1,600 K while the sublayer barely warms, sintering a slab without thermally cracking the substrate. Same cratering equipment. Same regolith feedstock. Different layer of microwave susceptor. You get fuel out of one process and a road out of the other.

This is not a slide deck. It is a closed mass loop with two issued US patents and three more in the same family.

The university that sells the dirt

Aqua Factorem and its sibling brick reactor are the public face. The quieter business is that UCF also owns the dirt every other space company tests against. Around 2018, planetary scientist Daniel Britt and engineer Anna Metke set up the Exolith Lab on UCF’s campus to manufacture high-fidelity lunar, Martian, and asteroid regolith simulants. In 2023, they spun the operation out as Space Resource Technologies. According to the company’s own page, they have shipped more than 300 tonnes of simulant to over 50 countries, and more than 400 peer-reviewed papers reference their products. NASA hardware, SpaceX hardware, and Blue Origin hardware bound for vacuum testing all eventually passes through buckets of UCF’s recipe.

The arithmetic is unsentimental. If you are a Tier-1 prime trying to certify a regolith excavator before flight, you are buying your test medium from a UCF spinoff. If you are a NIAC investigator filing a patent on a regolith processor, you are filing on top of UCF priority art. If you are a student team competing in NASA’s annual Lunabotics challenge, you will, on May 12 of this year, drive a robot through the world’s largest simulated south-pole lunar surface in Exolith’s test bin.

NASA spent the 1960s teaching American universities to make rockets. UCF, in the 2020s, has taught itself to sell shovels.

Why the literature has gone vertical

Patents are a lagging indicator. Look at the academic literature and the slope steepens. Filter OpenAlex for papers with “lunar regolith” in the title. Forty-eight in 2018. Seventy-five in 2019. By 2024 the number is 175. In 2025, a single year, it is 247 — five times the 2018 baseline. The first four months of 2026 already carry 92.

Some of that is China’s Chang’e-6 sample return reseeding the field with novel soil chemistry. Some is the Artemis program, finally about to put boots on the lunar south pole, where the ice is. But the through-line is constraint removal. Until ice was confirmed in permanently-shadowed regions in 2009, lunar industrial chemistry was a thought experiment. Once it was real, the question stopped being whether you could extract a kilogram of water on the Moon and became how cheaply. That is the question UCF kept answering, in five patents, while the cislunar startups raised seed rounds.

Who cares

Anyone whose investment thesis assumes a pure-play public lunar mining company is going to capture this market should reread their term sheet. The patent record says the floor for everyone else just got higher: the basic mechanical-separation approach to lunar water, and the basic microwave-sinter approach to lunar construction, are spoken for, owned by a research foundation that licenses freely to industry but binds whomever it licenses. Blue Origin’s 2025 lunar water grant exists; it does not look like a substitute. It looks like a different mousetrap on the same problem.

For corp-dev scouts, the lesson is geographic. The next decade of space-resource intellectual property will be defined by whoever owns the test medium, the patent priority, and the simulant pipeline. As of April 2026, that is one organization, in Orlando, that fits comfortably inside a single city block.

For aerospace journalists used to writing about Hawthorne and Kent: drive south. There’s a story in a warehouse next to a community college that hasn’t made the trade press yet, and it is older, denser, and farther along than the press releases coming out of New Glenn’s hangar.

The first private spacecraft is supposed to extract lunar water before the decade is out. Whoever does it will, almost certainly, run on a machine whose priority art reads: assignee, the University of Central Florida Research Foundation; inventor, Philip Metzger; filed March 13, 2020.

Method note. Patent counts come from the USPTO grant record; the underlying corpus is 9.3 million US utility grants pulled from USPTO bulk grant XML. We filtered grants from 2008 through April 21, 2026 whose titles match “lunar,” “regolith,” or “cislunar,” and excluded obvious false positives like cosmetic plant cultivars and toddler shoes. Each company’s count combines variant spellings of its assignee name. Patent text excerpts are from the issued grant claims and abstracts. Literature counts come from OpenAlex, filtered to works whose titles contain the exact phrase “lunar regolith.” Aqua Factorem power figures and mechanism details come from Philip Metzger’s NIAC Phase I report (NASA NTRS 20230008775) and the issued claims of US 12,305,514. Space Resource Technologies tonnage and country figures are self-reported on the company’s about page. We have not independently audited license terms; the framing that UCF holds priority on the basic approach is based on the patent record we can see, not on litigation outcomes that have not happened yet.
