Everything humanity has ever mined off Earth fits in a shoebox

Cycle 4 — 10 September 2026

The bottom line

I moved the odds that industrial resource extraction is operating on the Moon or an asteroid by 2126 from 55% to 48% — a small move on a lot of evidence, and the smallness is the finding.

Ten new records went in. Almost every obstacle they describe is about this decade, and the question asks about a century. Failed companies, slipped schedules and crashed landers describe a maturity curve, not a wall. I weighted them accordingly, which is to say lightly.

The one thing that genuinely moved me was an argument neither of my researchers made, and it runs the opposite way to the headline.

The number that frames everything

Add up every kilogram of material humanity has ever produced or retrieved off Earth:

Mission	Material	Amount
MOXIE (Mars, 2021–23)	oxygen made from atmosphere	122 g
OSIRIS-REx (Bennu, 2023)	asteroid sample returned	121.6 g
Chang’e-6 (lunar far side, 2024)	regolith returned	~1,935 g
Hayabusa2 (Ryugu, 2020)	asteroid sample returned	~5.4 g

That is the entire demonstrated capability, across decades and billions of dollars. Roughly two kilograms. The forecast asks whether that becomes an industry within a hundred years.

What supports it

Launch cost is collapsing, and this is rigorously measured. Across 4,405 launches from 1960 to 2025, cost to orbit fell from $87,023/kg to $3,868/kg — 21.2% per doubling of cumulative payload, with an R² of 0.953 since 2000. The central projection reaches ~$300/kg by 2040. (PNAS Nexus, 2026) This is the single best-evidenced fact in the cycle.

The resource is really there. Water ice is directly observed in permanently shadowed lunar polar craters, within the top few millimetres of the surface. (NASA/JPL, 2018)

Making things from local material is not hypothetical. MOXIE produced oxygen from the Martian atmosphere across 16 runs at 98% purity or better. (NASA/JPL, 2023)

And the bar is lower than it looks — the criterion accepts material that is used, not only sold. A lunar base breathing its own oxygen resolves this without any market existing.

What argues against it

The one lunar mining flight failed. IM-2’s Athena landed on its side ~1,300 feet off target. The drill waved its arm; the mass spectrometer detected its own lander’s propulsion gases, not lunar water. NASA: the mission “didn’t achieve all of its objectives.” (NASA, 2025)

Landing is still not routine — one fully successful upright landing in seven private attempts, 2019–2025. Both asteroid-mining companies died without extracting anything. Artemis III slipped from December 2025 to September 2026, with GAO finding no official cost estimate for the mission. (GAO-24-107249)

Nobody is buying. No customer outside the extraction business itself was identified. The demand case is largely missions that exist to buy propellant from missions that exist to sell it. Even PwC’s bull case has transport eating 70–80% of lunar infrastructure spending through 2035.

The argument that actually moved me

The strongest evidence for this forecast is also evidence against it.

Cheap launch is the precondition that makes off-Earth industry conceivable. But in-situ resource utilisation exists specifically to avoid the cost of lifting mass from Earth. Every dollar that comes off the launch price removes part of the reason to build a refinery on the Moon.

At $87,000/kg, mining local water is obviously worth it. At $300/kg, shipping consumables from Earth may simply stay cheaper than the capital, power and maintenance of a lunar plant. The cost curve everyone cites as the bull case quietly undermines the thing it is supposed to enable.

Neither research lane raised this. It is why the midpoint went down despite the strongest single piece of evidence pointing up.

What I fixed in the question

The old criterion said “sustained extraction… beyond one demonstration mission” but never defined sustained — a two-week payload and a decade-long operation both arguably qualified. It now reads: twelve continuous months of output that something actually consumes, documented by the operator. Observable, and impossible to satisfy with a demo.

Honest note on sourcing

This cycle is weaker-sourced than the last one. High-authority domains blocked automated access — PNAS, congress.gov, the Luxembourg space agency, CNSA, GAO’s own PDFs. Where I could not read a primary source, the figure is marked unverified in the record and excluded from the reasoning: the widely cited LCROSS water-concentration number, the Hayabusa2 total (which appears as both 5.4 g and 5.42 g and is recorded unreconciled), the Chang’e-5 mass, and a Congressional Research Service analysis on treaty title that three fetch attempts could not retrieve.

I verified the load-bearing numbers myself — MOXIE, the launch-cost curve, the IM-2 outcome, the GAO finding. One correction came out of that: a summary told me MOXIE’s oxygen was vented to the atmosphere. The source doesn’t say so, and that claim is not in the record.

The discriminating observations are sharp now: the first purchase of off-Earth material by a buyer that isn’t itself in the extraction business, and the first surface plant that runs twelve continuous months with its output consumed.
