Why are governments spending tens of billions of dollars to return to the Moon more than fifty years after Apollo?
The short answer. three reasons overlap. The first is strategic: the United States and China both see a sustained lunar presence as a marker of technological leadership, and China's stated goal of landing astronauts before 2030 has turned the programme into a race. The second is legal and diplomatic: whoever operates on the Moon first will shape the norms for resources, safety zones and coordination, which is what the US-led Artemis Accords (76 signatories by September 2026) and the China-led International Lunar Research Station are competing to define. The third is scientific and practical: the poles hold water ice that could supply life support and propellant, and the Moon is a test bed for the systems needed for Mars.
Three motives
| Motive | What it means in practice | Evidence |
|---|---|---|
| Strategic competition | Being first to land crew in this era; building infrastructure that others must use | NASA statements framing China as the pacing competitor; China's pre-2030 crewed landing goal |
| Rule setting | Norms for resource use, safety zones, data sharing and debris | Artemis Accords; ILRS agreements |
| Science and capability | Ice at the poles, far-side astronomy, geology; rehearsal for Mars | NASA science priorities; Moon to Mars architecture |
The Artemis Accords
The Accords are a set of bilateral political commitments between NASA (through the US State Department) and partner governments, first signed in October 2020. They are not a treaty. They commit signatories to transparency, interoperability, emergency assistance, registration of objects, release of scientific data, protection of heritage sites, deconfliction of activities through "safety zones", and the principle that extracting and using space resources is consistent with the Outer Space Treaty.
Exhibit 3.1
Signatories rose to 76 by September 2026, 17 of them in 2026
Artemis Accords signatories · signatories
| Measure | Value | Source |
|---|---|---|
| Signatories, September 2026 | 76 | NASA, Wikipedia snapshot |
| Added in 2026 | 17 | Payload |
| Share of the world's nations | Nearly 40% | NASA |
| Recent signatories | Oman (61st, Jan 2026), Jordan (63rd, Apr 2026) | Agency reports |
The growth matters for economics because signatories are the pool of likely partners, payload customers and astronaut-seat buyers for the US-led architecture. Several European, Asian and Gulf signatories already pay for instruments, landers or astronaut seats (Chapter 44, Chapter 45, Chapter 46).
The International Lunar Research Station
China and Russia announced the ILRS in 2021 as a joint robotic and later crewed research base near the lunar south pole. Membership counts vary between sources, from 13 to 17 countries and organisations, including Azerbaijan, Belarus, Egypt, Pakistan, Serbia, South Africa, Thailand, Venezuela, Kazakhstan and Senegal. China leads the hardware; Russia's role has shrunk since its Luna 25 lander crashed in August 2023, but the two have discussed a jointly built lunar power reactor for 2033–2035 (Chapter 42).
Why now and not twenty years ago
Three things changed between 2010 and 2026:
1. Launch became cheaper. Reusable rockets cut the price of reaching orbit several-fold (see the S5 Launch study), and fully reusable heavy rockets promise a further step.
2. NASA learned to buy services. Commercial cargo and crew to the International Space Station showed that fixed-price contracts with private companies could deliver capability at lower cost than government-owned systems. CLPS (Chapter 12) and the human landing system contracts (Chapter 8) apply the same model to the Moon.
3. Evidence of water ice firmed up. Orbital and impact data from 2008–2010 turned polar ice from a hypothesis into a mapped, if uncertain, resource (Chapter 30).
Why the economics are still government-led
No private customer today pays enough to sustain lunar transport on its own. The commercial lander companies earn most of their lunar income from NASA task orders; other income comes from foreign agencies, universities and a small number of private payloads. This is the core economic fact of the Moon in 2026: demand is political, and the market's size is set by budgets (Chapter 11) rather than by sales.
What would change this view
A large private buyer of lunar products (helium-3 for quantum computing is the only credible candidate so far, Chapter 32), a sharp fall in transport cost from fully reusable landers, or a political decision in Washington or Beijing to scale back would each change the balance between strategic and commercial motives.
