In 2015, astrophysicist Neil deGrasse Tyson predicted that the world’s first trillionaire would be the person who exploits the natural resources on asteroids. In 2023, NASA’s OSIRIS-REx mission returned 122 grams of rock from the asteroid Bennu — about the weight of a deck of playing cards — after a seven-year round trip. Those 122 grams are the total quantity of asteroid material humanity has successfully retrieved from space and brought to Earth. The gap between the promise and the operational reality is the entire story of asteroid mining in 2026: the resources are real, the physics is plausible, the companies exist, and nobody has extracted a single commercially viable gram of anything from any asteroid, ever. Two of the three most prominent companies from the 2010s hype cycle are dead. The current generation is further along, more technically grounded, and still years away from proving the business case.
What’s actually up there
The resource thesis is not speculation. Metallic M-type asteroids are more than 90 percent iron by mass and contain concentrated deposits of platinum-group metals — platinum, palladium, rhodium, iridium, ruthenium, and osmium — at densities 1,000 to 10,000 times higher than terrestrial ore bodies. A single metallic asteroid a few hundred meters across could theoretically contain more platinum-group metals than have been mined in all of human history. The concentrations aren’t evenly distributed and haven’t been verified by direct assay on more than a handful of samples, but spectroscopic surveys of near-Earth asteroids and laboratory analysis of metallic meteorites consistently support the thesis.
The value density is staggering at current spot prices. Rhodium trades at approximately $334,000 per kilogram as of early 2026. Iridium is roughly $215,000 per kilogram. Platinum sits at about $67,000 per kilogram. Palladium is around $55,000 per kilogram. AstroForge — the most visible PGM-focused mining company — estimates that a successful mission returning 1,000 to 2,000 kilograms of refined PGM material would be worth $70 to $140 million. The margins on asteroid-sourced PGMs, the company claims, could reach 85 percent — compared to roughly 7 percent for terrestrial PGM mining. Those are projections built on assumptions that haven’t been tested in a single real extraction, but they explain why venture capital keeps writing checks.
The second resource thesis — and arguably the more economically near-term one — isn’t precious metals at all. It’s water. Water is worthless on Earth and enormously expensive to launch to orbit. Carbonaceous C-type asteroids contain significant water ice that can be extracted thermally, electrolyzed into hydrogen and oxygen, and used as rocket propellant. The value proposition isn’t selling water on Earth. It’s selling it in space, where every kilogram of propellant you don’t have to launch from the surface saves thousands of dollars in launch costs. This is the thesis that TransAstra and Karman+ are building toward — not Earth-return mining but in-space resource utilization that creates a supply chain for the growing orbital economy.
Who’s actually trying
The 2010s generation is gone. Planetary Resources, founded in 2010 with backing from Larry Page, Eric Schmidt, and James Cameron, was acquired by a blockchain company called ConsenSys in 2018 — a sentence that tells you everything you need to know about what happened. Deep Space Industries, founded in 2013, was acquired by Bradford Space in 2019 and pivoted entirely away from mining. Both companies burned through tens of millions of dollars without getting a spacecraft to an asteroid.
The current generation is leaner, cheaper, and further along — but not yet successful. AstroForge, founded in 2022 in Huntington Beach, California, is the highest-profile PGM-focused company. Its first mission in April 2023 launched a microwave-sized satellite carrying simulated asteroid material and an onboard refinery designed to demonstrate that metal processing could work in microgravity. The solar panels wouldn’t deploy initially, the satellite wobbled, communications were intermittent, and the simulated extraction was never completed. Its second mission, Odin, launched in February 2025 with the goal of flying to asteroid 2022 OB5 and capturing imagery for a future mining mission — the first commercial deep space mission to target an asteroid. AstroForge lost contact with the probe approximately 20 hours after deployment. The company titled its debrief “Odidn’t.” Its third mission, Vestri, is scheduled for 2026 and aims to land on the target asteroid and take measurements for future extraction. AstroForge’s plan is to vaporize asteroid ore and use magnets to separate the metal in space, then return refined PGMs to Earth with a heat shield and parachute — all for less than $10 million per mission.
TransAstra, founded by Joel Sercel, has the deepest research portfolio and the most NASA institutional backing. The company partnered with NASA in 2019 to build MiniBee, a prototype demonstrating “optical mining” — using concentrated sunlight inside a capture bag to heat and extract water and volatiles from carbonaceous asteroid material. TransAstra’s full architecture, called Apis, envisions harvesting up to 100 metric tons of water from a single near-Earth asteroid and delivering it to lunar orbit, all from a single Falcon 9 launch. The company is pursuing near-term revenue from space tug and debris capture contracts while developing the longer-term mining infrastructure. Sercel himself has cautioned that mining PGMs and returning them to Earth is “not a near-term prospect” — TransAstra is building the enabling infrastructure, not going straight for the ore.
Karman+, the newest of the three, plans to go directly to an asteroid in 2026 and test excavation equipment. The UK-based Asteroid Mining Corporation is taking a different approach entirely — focusing on terrestrial applications that generate immediate revenue to fund future space operations, explicitly avoiding the venture capital treadmill that killed the 2010s generation.
Why the economics don’t close yet
The physics of reaching an asteroid is not the hard part — some near-Earth asteroids are actually energetically closer to reach than the Moon. The hard parts are everything that happens after arrival. Anchoring to a body with negligible gravity. Extracting material in microgravity, vacuum, and temperature extremes ranging from -270°C in shadow to +120°C in direct sunlight. Processing raw material into something refined enough to be worth returning to Earth. Packaging it in a reentry vehicle that can survive atmospheric entry. Recovering it on the surface. Doing all of this robotically, with round-trip communication delays measured in minutes to hours, on a spacecraft that launched for less than $10 million.
No one has demonstrated any of these steps at commercial scale. OSIRIS-REx proved sample return is possible — at a mission cost of approximately $1 billion for 122 grams. AstroForge’s thesis is that commercially focused hardware, riding on cheap SpaceX launches, can do it for orders of magnitude less. That thesis hasn’t been tested. The company’s first two missions both failed to achieve primary objectives.
The market problem is equally real. Platinum-group metals are valuable precisely because they’re rare — global annual platinum production is roughly 190 metric tons. Introducing significant asteroid-sourced supply would depress prices, potentially destroying the economics that justified the mission. The rare earth elements market has this same structural vulnerability — the value exists because of scarcity, and the mining operation undermines the scarcity it’s exploiting. AstroForge’s planned 1,000-to-2,000-kilogram returns per mission would represent roughly 0.5 to 1 percent of annual platinum production, which is probably absorbable. But the pitch to investors involves scaling far beyond that, and the price impact of scaling has no historical precedent.
The water-in-space thesis avoids the price-depression problem because the market doesn’t exist yet — there’s no orbital propellant depot competing for customers. But it requires the orbital economy to develop enough that in-space refueling becomes a real market rather than a theoretical one. SpaceX’s Starship architecture could either create that market (by generating demand for in-orbit propellant transfer) or destroy it (by making Earth-to-orbit launch so cheap that space-sourced water has no cost advantage).
Where it sits
Asteroid mining is simultaneously the most over-hyped and most under-appreciated resource play in the Moonshot 2169 landscape. Over-hyped because no company has extracted anything from any asteroid commercially, two out of three 2010s pioneers are dead, and the current leader has failed two of its first two missions. Under-appreciated because the resource concentrations are real, launch costs have dropped 100x since the concept was first proposed, and the three surviving companies are technically more credible than anything that existed a decade ago. The Outer Space Treaty of 1967 doesn’t explicitly prohibit commercial resource extraction — the 2015 U.S. Commercial Space Launch Competitiveness Act explicitly authorized it — but the legal framework for property rights, environmental liability, and international disputes in space mining remains essentially unwritten.
The constraint isn’t physics. It isn’t law. It isn’t even money. It’s the gap between “we know the resources exist” and “we’ve proven we can get them” — a gap that AstroForge’s Vestri mission in 2026 is designed to narrow. If Vestri successfully lands on an asteroid and takes measurements, it won’t prove asteroid mining works. It will prove that the next mission has a target worth mining. That’s not a commercial breakthrough. It’s the beginning of a beginning. We cover asteroid mining alongside fusion energy, solid-state batteries, space elevators, and 20 other unfinished machines across our Technology Moonshots course — where “done” means boring, measurable, and operable on a random Tuesday, and nothing about asteroid mining is done yet.
