The ambition to expand humanity beyond Earth’s ecosystem and into the solar system requires a foundational economic engine. For Jim Keravala, the CEO and Chief Architect of Offworld, that engine is mining. Caravala notes that the first stage of industrialization, whether on Earth or extraterrestrially, is typically mining, followed by construction, manufacturing, and fabrication.
Offworld’s vision is built on this sequence, pioneering a revolutionary swarm robotic mining architecture.
“The premise around Offworld is really born from our vision and passion about seeing humanity expand beyond Earth’s ecosystem into the solar system,” Caravala explains.
The Robot Puppies and 24/7 Mining
Offworld focuses its efforts on autonomous robot fleets. These robotic systems are built on a modular, common platform, allowing for multiple “species” of robots that operate like “swarms of large ant”. Caravala affectionately refers to them as “little robo puppies”.
The immediate goal is to deploy this intelligence architecture to have hundreds, if not thousands, of these robots mining, constructing, and manufacturing on the Moon, Mars, and eventually in free space.
While these robots consume heavy duty power—ranging from 2 kilowatts steady state to about five or six kilowatts peak during heavy work—they are designed for maximum efficiency. Based on the energy density of modern batteries, each robot can sustain a “good shift” of about 6 to 8 hours runtime. To ensure productivity, the architecture incorporates battery swap robots that can replace power packs quickly, allowing the entire system to run 24/7.
Saving Earth First: Liberating Billions in Minerals
While the ultimate destination is space, Offworld’s technology is already impacting Earth. The company has deployed pilot robotic programs in open pit and underground mines, targeting high-value metallic critical minerals such as platinum, copper, nickel, and rare earths.
The biggest initial business case on Earth involves tackling hundreds, if not thousands, of end-of-life underground mines. These are mines where conventional processes have become too uneconomical to continue. Crucially, when an underground mine reaches this threshold, there is often 30 or 40% of the ore still left inside.
“The mining companies are desperate to find ways to reactivate the mines that they’re not burdened with all these liabilities,” Caravala states.
Offworld’s autonomous robots can harvest this remaining mineral and “liberate billions of dollars of mineral” without putting a single person inside the mine. This capability makes the technology a “game changer for mining there on Earth as well,” proving it is not just logical for asteroid or lunar mining.
The Technological Leap: Touchless Mining
The path to efficiency involves radical technological innovation, particularly the development of “touchless mining”.
Caravala explained that they leveraged tooling developments in microwave and electric pulse beam energy. This energy is used to directly break the grain boundary bonds of the rock. The core physics behind this approach is that all crystalline and amorphous rock is 10 times stronger when compressed than when pulled apart (tensile strength).
Instead of trying to crush the rock, Offworld uses fluctuating microwave beams or a gigawatt electropulse shock in a few nanoseconds to get inside the rock and push it apart. By attacking the grain boundary bonds directly, they can reduce the energy used by about 10 times.
This innovation, paired with processing robots that refine and separate metal ions as close to the rock face as possible, offers profound economic benefits. Currently, typical mining operations haul out millions of tons of ore every year that is less than 1% metal grain (99% waste rock). This crafting process consumes 3 to 4% of the world’s energy costs globally.
Instead, the Offworld vision involves processing robots that grow ingots of pure metal. By taking out only hundreds of thousands of kilograms of pure metal instead of millions of tons of waste rock, they could reduce the cost of mining by an order of magnitude (10x), and save another order of magnitude through refined processing.
If this proves feasible, Caravala believes it would be “the biggest game changer of the last 10,000 years of mining”.
The Business of Space: Finding Revenue Fast
While the technology is advanced, Caravala stresses that the biggest challenge has been navigating the “psychic” economic nature of the commodities world. As prices fluctuate, the mining industry’s appetite for exploring new technologies “waxes and wanes”.
His advice for anyone starting a space business is rooted in this economic reality: what may seem like a cliché is profound wisdom—find customers and get to revenues as quickly as possible.
He advises that investment should be a supplement to annual recurring revenues (ARR). The market uncertainties for companies operating beyond Low Earth Orbit (LEO) and Geostationary Orbit (GEO) are too significant in 2025 to confidently close a business case based on the 10- or 12-year return-on-investment timelines common in infrastructure or oil and gas.
The key takeaway is that “there’s no such thing as a space business; there’s just business,” and focusing on annual recurring sales is the required baseline to mitigate risk and sustain operations.
