When most people think about space exploration, they picture massive rockets launching from Cape Canaveral, astronauts aboard the International Space Station, or major agencies like NASA and the European Space Agency (ESA). Yet one of the most active centres for preparing the next phase of space exploration is located in a much smaller country: Luxembourg.
Over the past decade, Luxembourg has been steadily building an ecosystem focused on space resources – the idea that materials found on the Moon, asteroids, and other celestial bodies could be used to support future missions and potentially enable new economic activities in space. At the centre of this ecosystem is ESRIC, the European Space Resources Innovation Centre, which brings together research institutions, space companies and entrepreneurs working on technologies that could allow humans to use resources beyond Earth.
With a growing presence of international companies and new research infrastructure under development, Luxembourg is positioning itself as a key contributor to the emerging field of lunar and asteroid resource utilisation.
Why Space Resources Matter
Traditionally, everything needed for a space mission must be launched from Earth. Rockets carry fuel, water, oxygen, construction materials and scientific equipment. Because escaping Earth’s gravity requires enormous energy, sending mass into space is extremely expensive. The concept of space resources, often called in‑situ resource utilisation (ISRU), proposes a different approach. Instead of transporting everything from Earth, future missions could rely on materials already available in space.
Examples include:
- Water ice on the Moon, which could be converted into drinking water, breathable oxygen, or spacecraft propellants.
- Lunar soil (regolith) that could be processed into construction materials for landing pads, roads, or habitats – or used to chemically extract oxygen.
- Asteroids containing water, carbon and other useful elements that could support propellant production and manufacturing in orbit.
Using local resources could dramatically reduce the cost of long-duration missions and make sustainable exploration, such as permanent lunar bases or future missions to Mars, far more feasible.
Many space agencies are actively investigating these possibilities. In ESA’s strategic roadmaps, ISRU is consistently presented as a foundational capability for sustainable exploration and European strategic autonomy in space. NASA’s Artemis programme and ‘Moon to Mars’ architecture, which aims to return astronauts to the Moon later this decade, places strong emphasis on technologies capable of using lunar resources. Luxembourg recognised early that this emerging field could become strategically important.
Luxembourg’s SpaceResources.lu Initiative
Luxembourg already plays a major role in the global satellite communications sector, hosting companies such as the SES global space solutions company. Building on this heritage, the government launched the SpaceResources.lu initiative in 2016, aiming to support research, attract companies, and create a legal and financial framework for space‑resource activities. Rather than focusing on launch capabilities, Luxembourg’s strategy has been to build an ecosystem that combines:
- Research and technology development.
- Industrial partnerships.
- Start-up creation and support.
- International collaboration.
ESRIC is an important pillar of this strategy.
ESRIC: A European Hub for Space Resources
ESRIC, launched in 2020, is a joint initiative of the Luxembourg Space Agency (LSA) and the Luxembourg Institute of Science and Technology (LIST) in strategic partnership with the European Space Agency (ESA). Its objective is to develop Luxembourg into a centre of expertise for space resources, connecting scientific research, engineering and entrepreneurship. The centre focuses on three main areas:
- Scientific research on resource identification and quantification.
- Technology development for extraction and processing systems.
- Support for innovation, startups and the space resources community.
This integrated approach helps translate academic research into technologies that could eventually be used in real lunar or asteroid missions. ESRIC also organises the annual Space Resources Week conference, the fifth edition of which attracted more than 490 attendees from 35 countries to the city’s Kirchberg district in early May 2026.
Studying the Materials of the Moon and Asteroids
Before resources can be used in space, scientists need to understand the properties of extraterrestrial materials. Lunar regolith, for example, is extremely fine and abrasive. Formed by billions of years of meteorite impacts, it behaves differently from soil on Earth and can damage machinery or interfere with mechanical systems.
Researchers working with ESRIC study these materials using regolith simulants: laboratory-created substances that mimic lunar or asteroid soil. These simulants allow engineers to test excavation systems, processing techniques and construction methods under realistic conditions. Important research questions include:
- How can oxygen be extracted efficiently from lunar soil?
- Can lunar materials be used to produce metals or structural components?
- What mineral processing technologies function best in low gravity and without water?
Understanding these processes is essential before any real industrial activity in space becomes possible.
A Growing Industrial Ecosystem
Luxembourg’s strategy has attracted several international companies active in space exploration and related technologies. One of the most prominent is ispace Europe, the Luxembourg-based subsidiary of the Japanese company ispace.
The company developed the TENACIOUS lunar micro-rover – designed, manufactured and assembled in Luxembourg – which was integrated into ispace’s Hakuto-R Mission 2. Although the mission’s lander did not survive touchdown, the development of TENACIOUS marked a significant milestone as the first European-built rover to reach lunar orbit. ispace Europe is also leading the ESA-backed MAGPIE (Mission for Advanced Geophysics and Polar Ice Exploration) project, a robotic lunar rover mission focused on prospecting and analysing potential water-ice resources near the Moon’s south pole.
Another important actor is Lunar Outpost, a US company specialising in robotic mobility systems for planetary exploration. The company develops rovers designed for lunar missions, including vehicles capable of prospecting for resources or supporting astronaut operations.
GomSpace, headquartered in Denmark and also established in Luxembourg, is a leading developer of CubeSats and small satellite systems for exploration and communications infrastructure. Its technologies support ESA’s Hera planetary defence mission, including the Juventas CubeSat. In collaboration with Luxembourg’s EmTroniX, which contributes expertise to the CubeSat’s low-frequency radar system designed to probe the internal structure of the asteroid Dimorphos, the mission advances asteroid science and planetary defence research.
Just recently, Blue Origin opened a European office in Luxembourg, marking another step in the country’s growing involvement in lunar exploration and space-resources activities. As part of this collaboration, Blue Origin and Luxembourg are working together on the Oasis-1 mission, which aims to map lunar resources from an ultra-low orbit. The mission will search for key materials such as water ice, helium-3 and rare earth elements, helping scientists to better understand where valuable resources may be located on the Moon. Developed by Blue Origin’s Luxembourg office and its Space Resources Center of Excellence in Los Angeles/USA, the project is carried out with the support of local partners GomSpace and ESRIC. These connections help ensure that the technologies and research developed in Luxembourg remain aligned with upcoming exploration missions.
Testing Technologies for the Lunar Environment
Developing technologies for the Moon presents a major engineering challenge. Equipment must operate in a vacuum, survive extreme temperature changes and handle abrasive lunar dust while functioning with limited power and maintenance.
To address these challenges, ESA and its partners are preparing a major new testing facility at ESRIC: the Dusty Thermal Vacuum Chamber (DTVC), scheduled to be installed in 2026 and operational in the following year. The DTVC will allow engineers and researchers to simulate the harsh lunar environment under controlled laboratory conditions for payloads up to 2.3 metres long, cycling between -180 and +160 degrees celsius in the presence of lunar dust simulants at high vacuum. This facility will make it possible to test robotic systems, excavation technologies, resource‑processing equipment and other hardware designed for lunar operations.
Having such infrastructure in Luxembourg will significantly strengthen Europe’s capabilities for developing and validating technologies related to lunar exploration and space resources.
Start‑Ups and Innovation
Alongside established aerospace companies, Luxembourg has worked to encourage start‑ups and entrepreneurial innovation. Luxembourg’s space resources ecosystem has fostered companies such as Maana Electric, which develops technologies to produce solar panels from locally available materials for sustainable energy generation in remote environments on Earth and, in the future, on the Moon.
Other emerging companies within the ecosystem focus on areas such as robotics and mobility systems, autonomous operations for lunar environments, resource extraction and processing technologies, and advanced materials and manufacturing techniques. By linking research institutions, industrial partners and new companies through ESRIC, Luxembourg aims to accelerate innovation in this still‑emerging field.
Looking Towards the Lunar Economy
The coming decade is expected to see a renewed wave of lunar exploration. NASA’s Artemis programme and several international missions aim to establish sustained human and robotic activity on and around the Moon. These missions will test technologies for extracting water, producing oxygen and using lunar materials for construction. If successful, they could mark the beginning of a lunar infrastructure supporting exploration, science and commercial activity.
The testing facilities, companies and research emerging from Luxembourg’s ecosystem — including the capabilities centred around ESRIC — could play a key role in strengthening Europe’s autonomous capacity in the future space economy, from resource utilisation and sustainable lunar infrastructure to advanced space technologies.
A Small Country with a Strategic Role
Luxembourg’s involvement in space resources illustrates how smaller nations can shape the future of space exploration and utilisation through strategic focus and international collaboration.
By combining research at institutions, such as LIST, and industrial expertise from companies across the spectrum from startups to global players, the country has created a growing ecosystem dedicated to the technologies of future lunar exploration. At the heart of this effort, ESRIC acts as a bridge between research, industry, and innovation, helping transform scientific ideas about space resources into technologies that could support humanity’s next steps beyond Earth.
While extracting resources from the Moon or asteroids remains a long-term challenge, the foundations for that future are already being built. Luxembourg has positioned itself as one of the places where that work is actively underway.
