The Race for Lunar Helium 3
Lunar Ambition: Startup Targets Rare Helium-3 on the Moon
Two former executives from Blue Origin, ex-president Rob Meyerson and lead architect Gary Lai, have taken a bold step with their new venture – a company aiming to mine helium-3 directly from the lunar surface and bring it back to Earth for commercial use.
The company, Interlune, kept its operations under wraps since its establishment in 2022. Yet, it recently made a splash by announcing a $15 million funding round on top of earlier angel investor backing.
This news carries significant weight because, while the investment amount may seem modest, the concept has the potential to disrupt the space industry entirely. There's been much chatter lately about developing a "lunar economy," but the specifics of this remain hazy. Most companies with plans for moon missions have focused on providing services or extracting lunar water for NASA or other clients tied to government contracts. In essence, no one has yet found a way to truly generate wealth off the moon itself – NASA remains the primary economic driver. It's a bit like a gold rush where the gold hasn't turned up yet.
Challenges and Aspirations
Interlune aims to change the game by extracting helium-3, an exceptionally rare and valuable resource on Earth. However, numerous challenges lie ahead. Firstly, the company needs to develop a way to efficiently separate the gas from lunar regolith, the moon's gritty, abrasive surface material. Then, they face the hurdle of transporting the helium-3 back to Earth – a logistical feat yet to be achieved. Finally, the company must establish a large, stable market for the isotope to sustain its operations.
Meyerson, however, stands undeterred. With NASA pouring billions into the Artemis Program for a lunar return, he believes the time is ripe to capitalize on the infrastructure and resources this program will provide for a pioneering lunar mining operation. The project would have been unimaginable just a few years ago – even now, its feasibility hangs in the balance.
"Helium-3 stands out as the one lunar resource whose value justifies the tremendous cost and effort of a retrieval mission," Meyerson stated in an interview. "The demand exists even today, with eager buyers lined up."
Helium-3: Potential Game-Changer
Helium-3 is a stable helium isotope containing two protons and a single neutron. The sun produces it through nuclear fusion, and solar winds carry it throughout the solar system. Due to Earth's magnetic shield, the isotope doesn't naturally occur here, with only trace amounts found from nuclear tests, reactors, and radioactive decay. It's a precious commodity, with a single litre costing thousands of dollars, leading to diligent recycling efforts by the US Department of Energy. On the moon, where there's no protective magnetosphere, scientists theorize that vast pockets of helium-3 are trapped within the regolith.
According to Meyerson, there's immediate interest in helium-3 from the fields of superconducting quantum computing and medical imaging. In the longer term, there's the tantalizing possibility of helium-3 fusion reactors – a long-held dream of scientists like Apollo 17 astronaut and geologist Harrison "Jack" Schmitt. Naturally, the scientific community remains divided on the ultimate practicality of this technology.
Nonetheless, Meyerson's core argument is that the scarcity of helium-3 has limited exploration into its commercial potential. He believes a reliable supply would trigger entirely new industries and applications.
Of course, that's all contingent on Interlune successfully finding, extracting, and shipping the helium-3.

Lunar Mining: The Challenge Begins
The cornerstone of Interlune's mission is creating a viable method for extracting gas from the moon's surface – a notoriously tricky task. Even though the estimated total amount of helium-3 on the moon is enormous, possibly surpassing a million metric tons, it's widely dispersed. The company might have to process a staggering amount of regolith to obtain a single usable gram of the isotope. With this in mind, Interlune has prioritized developing an energy-efficient extraction process.
The company's strategy hinges on a demonstration mission slated for 2026. This mission will sample the lunar soil, verify helium-3 concentrations, and then put their extraction system to the test. Meyerson envisions utilizing one of NASA's Commercial Lunar Payload Services (CLPS) missions for the launch – these private space ventures routinely fly payloads to and from the moon under contract with NASA.
"Our plan is to have a pilot plant in place by 2028, with full-scale operations for helium-3 recovery commencing by 2030," Meyerson outlined. "The goal is to meet the existing Earth-based demand for this resource."
Extraction and Lunar Transportation
The transportation logistics for bringing helium-3 back to Earth could be provided by SpaceX or Meyerson's previous company, Blue Origin. Both enterprises are actively developing reusable lunar landing vehicles and transportation infrastructure between the moon and Earth.
Interlune's latest funding round attracted notable investors, including Alexis Ohanian's venture firm, Seven Seven Six. The firm appreciates the near-term market demand for helium-3 but also recognizes the potential for exponential growth if large-scale lunar extraction becomes feasible.
"There are endless investment options out there, but some opportunities are true moonshots," explained Katelin Holloway, lead investor from Seven Seven Six. "This is literally the case with Interlune, and that's what makes it so thrilling. The impact may not be immediate, but it could shape the future for generations to come. Plus, the near-term applications for helium-3 solidify the business case for us, which is always a bonus."
The Competition Heats Up
Interlune isn't alone in seeing the economic potential of the moon. Several other companies have plans for establishing lunar operations, though not all focus on helium-3 extraction. For instance, Astrobotic Technology, a Pittsburgh-based firm, plans to start mining lunar ice at the moon's south pole. This water ice can be broken down into hydrogen and oxygen – crucial components for rocket fuel. In theory, this creates the potential for a lunar "gas station," refueling rockets for deeper space missions.
Another enterprise, ispace, based out of Tokyo, has similar plans for lunar ice mining. Additionally, several governments, notably China, have expressed keen interest in lunar resources and are developing their own plans for establishing a presence on the moon.
Risk vs. Reward
While the potential rewards of lunar mining are vast, so are the risks. Foremost is the sheer technological challenge of operating in the harsh lunar environment. The abrasive dust-like regolith wreaks havoc on moving parts and machinery, and temperatures swing wildly between extremes of hot and cold. Equipment failures far from Earth carry a whole new level of consequence.
Furthermore, the economics of space ventures are notoriously unpredictable. Even if Interlune can overcome the technical hurdles, the market demand for helium-3 might not develop as they project. If the price drops, the entire business model could crumble.
Yet, the lure of space remains strong. The potential creation of a true off-world economy is enticing, and the possible scientific and technological breakthroughs could benefit humanity as a whole. While the odds are long, ventures like Interlune represent the bold, risk-taking spirit that has often driven innovation. Whether they succeed or fail, they're pushing the boundaries of what we believe to be possible.
Ethical and Environmental Questions
Beyond the technical and economic challenges, mining on the moon raises profound ethical and environmental concerns. To date, exploration of space has mostly been conducted in the name of science and discovery. Transitioning to large-scale resource extraction marks a significant shift with potential repercussions.
Some experts worry about irreversible damage to the pristine lunar landscape. While desolate by Earth standards, the moon possesses a unique beauty and scientific value as a record of our solar system's history. Large-scale mining operations could forever alter it.
Others raise the specter of repeating historical patterns of exploitation. Will the benefits of a lunar economy flow mainly to a select few wealthy nations and corporations, echoing the colonialist exploitation of Earth's resources? There is a growing push to proactively establish international frameworks to ensure that any resources extracted from the moon contribute to the common good of humanity.
The Outer Space Treaty
The main legal document currently governing activities in space is the Outer Space Treaty, put forward by the United Nations in 1967. The treaty broadly prohibits nations from claiming sovereignty over celestial bodies like the moon. However, it leaves room for interpretation regarding the commercial exploitation of space resources.
In 2015, the United States passed the Commercial Space Launch Competitiveness Act, granting US companies the right to own and sell any resources they extract from asteroids or the moon. This legislation drew criticism, with some observers arguing it violates the spirit of the Outer Space Treaty.
In 2020, the Artemis Accords were unveiled, a NASA-led initiative seeking to establish guidelines for sustainable and peaceful lunar exploration. Countries like Australia, Canada, Japan, and the United Kingdom have signed on. Noticeably absent, however, are Russia and China, two key players in the modern space race.
A Precarious Balance
The development of a viable lunar economy will require a careful balancing act. On one hand, there's the urgent need to develop sustainable practices that ensure the benefits of space exploration don't come at the cost of irreversible environmental damage and ethical compromises. On the other hand, rigid regulations that stifle innovation could hamstring progress entirely, squandering the potential to kickstart revolutionary new industries.
The issue is further complicated because space-based business ventures carry an inherently high risk. Investors need some assurances and incentives to commit significant capital to such endeavors. Finding a viable path forward is crucial to avoid creating regulatory barriers that only the largest, wealthiest entities can overcome.
A Step into the Unknown
Ultimately, Interlune's quest to mine helium-3 on the moon serves as a microcosm of the broader questions facing humanity as the space frontier opens for business. Can we develop the technologies and frameworks to tap into the vast wealth of the solar system without repeating past mistakes? Will the fruits of lunar mining be used ethically, or will they simply fuel further inequality and conflict?
The answers to these questions remain veiled, likely to unfold over decades and even centuries. Yet, companies like Interlune, whether they ultimately succeed or not, are the first pioneers venturing into this uncharted territory. Their actions will have ripple effects for generations to come, shaping how humanity chooses to expand its footprint in the cosmos.
The Ripple Effects of Lunar Mining
If Interlune and other lunar mining enterprises do succeed, the implications extend far beyond just securing a supply of helium-3. The act of establishing a sustained human presence on the moon with large-scale industrial operations would create spill-over effects in various fields.
One major area likely to benefit is robotics and automation. The harsh lunar environment, coupled with the communication delays between Earth and the moon, necessitates a high degree of autonomy in lunar machinery. Innovations made to keep rovers drilling, digging, and processing regolith under minimal human supervision could find direct applications in terrestrial mining, deep-sea exploration, or hazardous waste cleanup projects.
Furthermore, developing the ability to extract and utilize resources in-situ (meaning directly in their place of origin) is crucial for any long-duration space missions. If we plan to send astronauts to Mars and beyond, we need to find ways to live off the land, so to speak. Mastering techniques for harnessing water ice, solar energy, and vital materials on the moon could become stepping stones for crewed missions to other parts of the solar system.
The technological advancements stemming from a lunar economy could also spur innovation back on Earth. Materials science breakthroughs might be needed to withstand the extreme lunar conditions, leading to new, ultra-durable alloys or composites. Energy storage and power generation advancements would be critical, perhaps fostering improvements in solar panels or creating better, more compact batteries on Earth.

A New Economic Frontier
Should lunar mining become commercially viable, it has the potential to disrupt entire industries. Access to a steady, off-planet source of helium-3 could revolutionize medical imaging technologies or make quantum computing more accessible. If fusion power ever becomes a reality, and helium-3 does prove to be a superior fuel, the global energy landscape could be completely transformed.
The economic shifts triggered by a lunar economy might not always be predictable. Just as the rise of the Internet created entirely new industries and job sectors, the ability to reliably source materials from space could lead to businesses and applications we can't even imagine today.
Of course, there's the looming possibility that the promised breakthroughs and economic windfalls never fully materialize. The history of innovation is also a history of expensive failures and overhyped technologies. Even if some lunar resources prove commercially viable, it might amount to a niche market rather than a global economic revolution.
Beyond the Economic Impact
The impact of Interlune's mission, and others like it, goes beyond the purely economic or technological. By attempting to turn a profit from exploiting extraterrestrial resources, companies like this will force us to have difficult conversations about ownership, ethics, and our long-term vision for humanity's role in space.
Success in lunar mining could reawaken a sense of optimism about the future. At a time when challenges like climate change, global conflict, and political polarization can feel overwhelming, seeing humanity reach out into the stars offers hope for a brighter future where these Earth-bound problems are overcome through cooperation and technological advancement.
Then again, it could end up highlighting all the worst aspects of human behavior – greed, short-sightedness, and the tendency to prioritize individual or national gain rather than working together for the greater good. Only time will tell which course we'll set.
The Long Game
For better or worse, it seems inevitable that the quest for extraterrestrial resources will become a major theme in the 21st century. The moon, being our closest celestial neighbor, is the logical starting point. However, asteroids rich in precious metals, or the ice-laden moons of Jupiter, might be next on the target list.
Whether Interlune ultimately succeeds in retrieving helium-3 is almost beside the point. Their ambition has sparked a conversation and, perhaps more importantly, ignited action toward establishing a functioning lunar economy. It remains to be seen if this will be a force for good, a source of conflict, or simply another overhyped technological dead end.
Yet, something profound shifts when we move from just exploring space to actively exploiting it. It marks a transition from seeking knowledge to pursuing profit, with enormous potential consequences, both positive and negative.
In the short term, the focus will likely be on practical matters. Interlune will either develop the technology to harvest lunar resources or it won't. Governments and space agencies will clash or cooperate over regulatory frameworks. Investors will weigh their risks and decide whether or not to throw their money behind lunar ventures.
However, the long-term implications are far more profound. If humanity can successfully establish a self-sustaining presence on the moon, supported by a thriving lunar economy, it opens the door to unimaginable possibilities. From the moon, we may one day launch missions to Mars or build vast orbital colonies, expanding our footprint across the solar system.
Conclusion
The resources of space could free us from the limitations of Earth. However, they could also deepen existing inequalities or become a new source of global conflict. It's a sobering thought that the choices we make today, driven by ambition and greed or foresight and cooperation, could ripple out and shape the fate of our species for centuries to come.
Only time will tell whether ventures like Interlune will be remembered as the pioneering steps towards a future where humanity thrives among the stars or as footnotes in a story of missed opportunities and misguided ambition. The future of space exploration, it seems, hangs precariously in the balance.
