What the UK Space Resources Review Establishes
The UK Space Agency published its independent space resources technology review on October 6, 2026, drawing on responses from 27 UK organizations. Prepared by Frazer-Nash Consultancy following a commission in 2025, the assessment identifies national capabilities in using materials found beyond Earth and examines how those capabilities could contribute to international exploration missions.
The UK ISRU Technology Review addresses in-situ resource utilization (ISRU), meaning the use of materials available at a mission destination to produce useful supplies. On the Moon, that could involve extracting oxygen from minerals or recovering water from icy ground. Its findings are explicitly informational and do not represent national policy or a commitment to fund the technologies described.
Its central finding is that UK space resources technology contains promising individual capabilities, but considerable development remains before those capabilities can operate as dependable production systems. Resource-measuring instruments have reached comparatively advanced stages. Many extraction and processing concepts remain laboratory projects, with unresolved questions about scale, environmental performance, and integration.
The survey received 29 responses, excluding two from organizations outside the UK. Among the remaining respondents, 18 represented industry, eight represented academia, and one represented a public body. Fourteen of the industrial respondents came from small or medium-sized organizations.
These figures describe the study’s participants rather than a complete national census. Participation was voluntary, and the review acknowledges that respondents’ interests and perceptions may influence its findings. The results offer evidence about the organizations engaged in this work, without establishing the total size of the UK industry.
The geographical emphasis was pronounced. In the survey underlying the October 2026 review, 85% of respondents identified lunar applications for their technology, compared with 44% for Mars. Technologies could serve multiple destinations, so those percentages are overlapping categories.
The review also restricts its scope deliberately. It concentrates on capabilities relevant to UK exploration priorities and gives particular attention to European and American missions. It does not claim to inventory every international technology or provide an exhaustive account of global competition.
That boundary matters when interpreting its recommendations. The assessment supports a strategy of contributing selected equipment, scientific expertise, and processing methods to larger international systems. It does not establish that the UK can independently deliver every element of a lunar industrial operation.
Useful Resources Require a Complete Production Chain
Lunar material becomes useful only after equipment can locate it, acquire it, and deliver an acceptable product to a user. The review organizes that progression into five broad stages: prospecting, excavation, beneficiation, processing, and products and purification. Beneficiation means preparing or concentrating raw material before further treatment.
This organization explains why a successful experiment can coexist with an incomplete industrial capability. An oxygen extraction reactor may work with a carefully prepared laboratory sample, yet depend on an undeveloped machine to provide material of the correct particle size. Its output may also require purification and storage equipment before a spacecraft can use it.
New Space Economy’s explanation of lunar ISRU production processes places those connections within the broader operating system. Excavation equipment and reactors depend on electricity, heat management, and reliable material transfer. These supporting systems consume mass and power that must be included in any assessment of the benefits of local production.
The UK review recognizes those dependencies but excludes detailed treatment of several enabling technologies because they serve activities beyond resource extraction. Power and communications fall into that category. Their exclusion narrows the study; it does not make them optional for an actual installation.
Oxygen illustrates the difference between resource abundance and product availability. In its 2020 description of a ground-based extraction facility, the European Space Agency (ESA) explained that lunar regolith, the loose dust and fragmented rock covering the surface, contains approximately 40% to 45% oxygen by weight. That oxygen is chemically bound in minerals and glass rather than available as breathable gas.
ESA’s oxygen extraction explanation describes using electricity and molten salt to release it. An industrial installation would also need to collect the gas and prepare it for a specified application. Breathing systems and rocket propulsion impose their own requirements for purity and delivery conditions.
Water presents a different set of dependencies. Its usefulness depends on concentration, physical form, and accessibility at a particular site. New Space Economy’s coverage of water in lunar materials explains why ice in cold polar terrain differs from small quantities of water-related material elsewhere on the surface.
The review’s process roadmapping tool makes these connections explicit. Users choose an intended product, assemble the functions required to produce it, and position candidate technologies within that sequence. For a developer, this exposes the equipment its own technology must receive material from and supply material to.
A national capability map can consequently serve as a procurement tool as well as a research inventory. It can identify where further investment would complete a production pathway, and where another isolated prototype would leave the same missing connections unresolved.
Prospecting Connects Scientific Instruments With Resource Decisions
The strongest capabilities identified in the review include instruments that determine what materials are present and how they are distributed. Such measurements are necessary before engineers can select a processing method or estimate how much useful product a site might supply. A scientific detection alone does not establish an economically recoverable deposit.
The Open University and RAL Space contribute to this area through miniature laboratories and gas-analysis instruments. Mass spectrometers, which identify substances by measuring electrically charged particles, can investigate gases released from heated samples. Those measurements help distinguish water from other volatile substances that escape when material warms.
ProSPA is a miniature laboratory developed for ESA’s Prospect payload. The October 2026 review assigns it technology readiness level six, indicating a level of development beyond basic laboratory proof but short of demonstrated operation in its intended mission. It combines sample handling with gas processing and analysis.
Prospect pairs that laboratory with Leonardo’s ProSEED drill. In an October 15, 2026 update, ESA described plans to drill as deep as 1 meter and transfer samples into the laboratory for heating to almost 1,000°C. The agency continued to identify 2027 as the planned mission year, with delivery on Intuitive Machines’ IM-4 mission.
The intended measurements address resource composition and extraction behavior. As of October 23, 2026, Prospect remains a planned scientific and technology investigation, rather than an operating mine or a demonstration of commercial production volumes. Its sampling work could help determine which later extraction experiments are justified.
Other instruments demonstrate why technical maturity must be separated from mission outcome. The review describes the Peregrine Ion Trap Mass Spectrometer, developed with UK participation, as having operated successfully in space during Astrobotic’s unsuccessful 2024 lunar landing mission. It gathered measurements during flight, but the lander did not reach the surface.
The University of Oxford’s Lunar Thermal Mapper provides another example. The instrument launched aboard Lunar Trailblazer in February 2025, but the spacecraft lost communications before accomplishing its intended lunar mapping work. The National Aeronautics and Space Administration (NASA) records the mission’s end as July 31, 2025.
Neither case supports treating the intended lunar observations as completed. They demonstrate that instrument development, successful operation, and delivery of useful resource information are separate milestones, each exposed to different risks.
Prospecting also has a possible commercial function before material production begins. Measurements can inform landing-site selection and equipment design, reducing uncertainty for later missions. That does not establish an existing market for all such data, but it explains why a country with strong scientific instrumentation could contribute without owning an extraction plant.
Moving and Preparing Regolith Deserves Equal Attention
Dust and fragmented rock must move reliably through equipment before many extraction processes can begin. The review identifies excavation, transfer, and handling as areas of UK activity with uses beyond resource production. Surface construction and scientific sampling also require machines that can interact with abrasive ground.
Amentum and the University of Manchester developed the Mobile Lunar Excavation and Size Separation System, known as MoLES³. The system combines a mobile excavation platform with equipment that separates collected material by particle size. The October 2026 review assigns the relevant development a technology readiness level of four.
ESA’s account of the 2025 Space Resources Challenge describes the team’s rover and static sieving unit. The system participated in testing at the LUNA facility in Cologne, where teams worked with lunar-like terrain and material under operational constraints. These were ground demonstrations, not lunar deployments.
Particle-size control has direct consequences for downstream equipment. A reactor designed for fine material cannot automatically accept the same mixture of dust and larger fragments that an excavator removes from the surface. Preparing a consistent input can reduce uncertainty in heating and material flow.
Imperial College London contributes research on electrostatic separation. This approach uses electrical forces to move or sort particles according to their behavior in an electric field. The review includes both mineral enrichment and particle-size separation concepts, placing them between excavation and processing.
These techniques could reduce the amount of unwanted material that must pass through an energy-intensive reactor. Their value still depends on how effectively they separate the actual material available at a mission site. Performance with a selected laboratory mixture does not establish performance with every lunar soil composition.
Construction-oriented research follows a related path. Lucideon’s flash-sintering work uses an electric field to assist the consolidation of regolith simulant into denser material. Sintering bonds particles through heating without requiring the entire material to become a freely flowing liquid.
The review describes laboratory feasibility under Earth conditions and identifies further work on vacuum operation and larger samples. These are important distinctions because a small test specimen does not demonstrate a usable landing pad or structural component. Mechanical properties must be measured for the intended shape and loading conditions.
The broader lesson appears in New Space Economy’s coverage of the international technology gap assessment. Resource acquisition and preparation influence the requirements of the processing equipment that follows. Funding a chemical extraction method without addressing its feedstock requirements can leave a technically successful project unable to function within a mission.
Oxygen Extraction Builds on Industrial Expertise
The UK review identifies oxygen and metal extraction as a concentration of national research and industrial capability. This work connects lunar exploration with established expertise in metallurgy, meaning the processing and study of metals. Its relevance comes from the chemistry of lunar minerals and the potential usefulness of both oxygen and the remaining metallic material.
Metalysis provides an example through molten salt electrolysis. Electrolysis uses electrical energy to drive chemical reactions, and this approach adapts a terrestrial metal-production process to oxygen-bearing lunar material. In ESA’s ground experiment, regolith simulant remained solid within molten calcium chloride heated to approximately 950°C.
The review records an earlier proof-of-concept result in which researchers extracted 96% of the oxygen from a lunar regolith simulant. That percentage describes extraction under the experiment’s conditions. It should not be interpreted as the overall efficiency of a complete lunar production installation, which would include energy consumption and equipment losses.
The proposed ISRU Demonstration Mission builds on this processing route. The review’s mission annex identifies OHB as the lead following earlier leadership by Thales Alenia Space UK, with UK organizations among the contributors. The October 2026 review lists the mission as proposed, with no confirmed launch date.
That description is more precise than treating the project as a fully scheduled UK lunar oxygen plant. The technology offers a route toward such a demonstration, but mission status and national participation require separate statements. An established industrial process on Earth still needs substantial adaptation for unattended operation beyond Earth.
Other approaches occupy earlier development stages. Frazer-Nash Consultancy’s Hydrogen Plasma Extraction from Regolith concept uses energized hydrogen to react with oxygen-bearing minerals and form water vapor. The water could then undergo electrolysis to recover oxygen and hydrogen.
The review assigns that concept technology readiness level two and describes concept design with supporting models. Those are useful development outputs, but they do not establish a working flight system. Because the review’s author also develops this concept, its inclusion should be understood as part of the disclosed capability inventory rather than an independently established ranking of competing methods.
Microwave processing offers another research direction. A demonstrator involving the University of Surrey, The Open University, and Added Value Solutions investigates heating regolith for resource extraction and structural-material production. The review places that work at technology readiness levels four to five.
A separate planetary demonstration shows both the promise and the scale still to be addressed. NASA’s Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) produced 122 grams of oxygen from the Martian atmosphere between 2021 and its final run in August 2023. NASA reports a peak production rate of 12 grams per hour at a purity of at least 98%.
The MOXIE results establish that oxygen production from a local planetary resource can work beyond Earth. They do not validate lunar mineral processing, because the feedstock and equipment are different. They also leave the development of sustained production and product storage to larger systems.
Water Purification Expands the Supplier Base
Extracting water and making it suitable for use are separate operations. A system may release water from icy material without removing substances that would interfere with drinking-water systems or downstream chemical equipment. The review includes technologies addressing both recovery and purification.
The Aqualunar Challenge brought additional organizations into this area through a prize competition conducted with Canadian partners. It supported development of technologies for purifying water associated with lunar ice. The competition illustrates how a clearly described technical problem can attract participants outside the established spacecraft supply chain.
Naicker Scientific’s SonoChem System won the UK competition on March 27, 2025, receiving a £150,000 prize. The official award announcement describes its use of sound waves to generate small bubbles in contaminated water. Conditions created within those bubbles support chemical reactions that remove contaminants.
The announcement also named RedSpace’s FRANK system and Queen Mary University of London’s AquaLunarPure as runners-up. Their proposed approaches address the same desired product through different treatment processes. None of those prize results constitutes evidence of operational lunar water production.
Interstellar Mapping’s Static Water Extraction System occupies another position in the review. It uses staged heating to release different volatile substances before recovering water. The October 2026 review assigns it technology readiness level five and describes validation of an experimental assembly in a relevant environment.
Regolithix’s Regolith Ice Plasma Purifier for Lunar Exploration, known as RIPPLE, proposes a sequence involving vaporization and particle separation before plasma processing. The review assigns it level four and identifies further development and environmental testing. Its proposed outputs connect water recovery with the production of hydrogen and oxygen.
The distinction between laboratory water treatment and lunar operation remains substantial. A treatment process must function within available electrical power and tolerate the physical conditions of the mission. Water also requires controlled pressure and temperature to remain in the form needed by the equipment.
Terrestrial applications offer a possible additional route for development. The Aqualunar announcement discusses the potential relevance of purification technologies to water problems on Earth. Such transfer remains an opportunity to test, rather than evidence that a lunar design will automatically outperform established terrestrial treatment methods.
For UK space resources technology, these projects widen the pool of contributors. They also create an integration task: a purification unit must accept the output of a particular extraction process, then supply water meeting the requirements of a specific user. Competitions can develop candidate components, but subsequent contracts must establish those interfaces.
Funding and Facilities Must Support Repeatable Systems
Most technologies described by the survey respondents were at technology readiness level five or below. The technology readiness level (TRL) scale runs from early scientific principles to systems proven through operation. A position on that scale describes maturity, but does not by itself establish production capacity or commercial viability.
The review makes that limitation explicit. Its TRL assessment did not incorporate scale, so a technology demonstrated successfully in a small application could still require extensive work before supporting sustained exploration. A mature instrument and a mature industrial plant cannot be treated as equivalent simply because both receive high scores.
Respondents repeatedly identified funding continuity as an obstacle. Industrial participants described incentives to build individual demonstration prototypes rather than repeatable systems. Academic participants described projects slowing or ending when short research contracts expired.
Those accounts are survey evidence rather than an independent financial audit. Even so, they identify a specific development problem: the funding available for an initial experiment may not connect to the funding needed for environmental testing and mission integration. A prototype can survive technically but lose its development team.
The review also maps facilities that could support more coordinated testing. The University of Manchester provides a lunar mechanical analogue testbed, and The Open University has thermal-vacuum and resource-processing facilities. Metalysis contributes electrolysis and analytical capabilities, with Lucideon supplying ceramic-processing infrastructure.
Access requires more than knowing that a facility exists. A developer needs suitable test conditions and enough time to investigate failures. The resulting measurements must also be usable by the organization responsible for integrating the equipment into a spacecraft or production system.
The review proposes that existing facilities could support a UK testing role for domestic and international developers. That possibility depends on coordination among facility owners and potential users. The publication does not establish that a funded national testing service already exists.
The most informative experiments would connect multiple stages of production. An excavation machine could supply a separation system whose output feeds a reactor, allowing engineers to measure how interruptions or changing material properties affect the complete chain. That would generate evidence unavailable from testing each device independently.
This is an engineering implication of the review’s functional mapping, rather than a claim that one particular architecture has already been selected. Its practical value lies in making test results relevant to the eventual mission. Equipment needs to demonstrate acceptable output over useful operating periods, including restarts and foreseeable faults.
Commercial Demand Depends on Delivery and Procurement
The review discusses potential economic benefits, but its technology inventory does not establish a present commercial market for lunar commodities. Producing a useful substance is only part of a business proposition. A supplier must also have a customer requiring that substance in a deliverable quantity and location.
New Space Economy’s discussion of space resource market evaluation explains why location changes value. Oxygen available beside an extraction reactor differs commercially from oxygen stored aboard an ascent vehicle. Transportation, storage, and transfer can determine whether the product reaches its intended user.
The appropriate comparison includes the complete cost of local production against the alternative of delivery from Earth. Production equipment itself must be transported, installed, and operated. Replacement parts and backup supplies can remain necessary even after a plant begins working.
Lower launch costs have competing effects on that calculation. They can reduce the cost of delivering extraction equipment, but can also reduce the cost of supplying consumables directly from Earth. The net effect depends on the mission architecture and how often the equipment operates.
New Space Economy’s coverage of lunar economy demand drivers connects resource production with the missions and infrastructure that would consume its output. Announced exploration ambitions are not equivalent to binding orders. A proposed plant serving infrequent missions faces a different utilization problem from one supplying regular transportation.
The UK review’s respondents requested clearer mission pathways and an initial government-funded mission. Such procurement could give developers a defined operating requirement and a route to flight testing. It would still need to distinguish the purchase of research from a commitment to buy recurring supplies.
International participation offers a more immediate route for many UK organizations. A supplier can provide an instrument or processing subsystem within a larger mission, gaining experience without financing an entire production chain. That approach also creates dependence on partner schedules and procurement decisions.
Regulatory clarity remains part of this commercial picture. The review records industry requests for clearer treatment of space resources and material already in orbit. It also describes the UK’s participation in international discussions about responsible resource use, but those discussions should not be presented as a complete operating framework already in place.
Technology selection consequently requires more than choosing the highest laboratory yield. The selected process must fit a customer’s mission and a realistic development budget. The UK review provides a way to organize that decision, but it does not substitute for product specifications, procurement commitments, or integrated operating evidence.
Summary
The UK space resources review identifies credible contributions in scientific instrumentation and material processing, supported by facilities that could assist further development. Its strongest commercial implication concerns how those contributions are assembled: a useful national position can emerge from supplying well-defined parts of international systems, without attempting to own every stage of resource production.
The next measurable advance would be a change in the evidence available to customers. Repeatable tests connecting material acquisition to an accepted final product would allow procurement decisions to rely on operating performance rather than separate component demonstrations. That would make capability maps useful for buying equipment and planning missions, as well as describing research.
Appendix: Top Questions Answered in This Article
What Is In-Situ Resource Utilization?
In-situ resource utilization means using materials available at a mission destination to produce useful supplies. Lunar applications include recovering water or extracting oxygen from minerals. The process extends beyond extraction because material must also be prepared, purified, and delivered in a form that equipment or people can use.
What Does the UK Technology Review Establish?
The review identifies UK capabilities and development needs in space resource technologies. It draws on a survey of 27 UK organizations and examines selected technologies within a production chain. Its findings are informational, and publication does not constitute national policy or a funding commitment for the projects it describes.
Which UK Capabilities Are Comparatively Advanced?
The review identifies resource prospecting instruments among the UK’s more mature capabilities. These instruments measure material composition or investigate gases released from samples. Some have operated in space, but instrument operation does not necessarily mean that a mission completed its intended lunar resource measurements.
What Will Prospect Investigate?
Prospect is a planned European lunar investigation combining a drill with a miniature laboratory. It is intended to collect subsurface material and examine gases released during heating. ESA’s October 2026 description continued to identify a planned 2027 mission, with measurements supporting scientific understanding and resource-use experiments.
Can Oxygen Be Extracted From Lunar Soil?
Ground experiments have demonstrated oxygen extraction from material designed to resemble lunar regolith. The oxygen is chemically bound in minerals, requiring energy and processing equipment to release it. Those results support further development, but they do not establish a complete production system operating on the Moon.
Why Does Particle Size Matter?
Processing equipment requires material with physical properties suitable for its design. Excavated regolith contains particles of different sizes, which can affect movement and heating inside equipment. Sorting that material can provide a more consistent input, although the separation system itself must operate reliably under the mission’s conditions.
What Did the Aqualunar Challenge Achieve?
The Aqualunar Challenge supported development of technologies for purifying water associated with lunar ice. Naicker Scientific’s SonoChem System won the UK competition in 2025, with RedSpace and Queen Mary University of London named runners-up. These awards recognized development work rather than successful water production on the lunar surface.
Does a High Technology Readiness Level Establish Commercial Viability?
A high technology readiness level indicates substantial technical development or successful operation in a defined setting. It does not establish profitability or adequate production capacity. The UK review explicitly notes that its readiness assessment did not account for scale, which remains important when moving from experiments to sustained supply.
Why Is Continuous Funding Important?
Respondents described gaps between early research and later development, with short funding periods interrupting teams and projects. Sustained production requires testing beyond an initial prototype. Environmental qualification and integration with other equipment can demand additional work before a customer has enough evidence to select a system for flight.
What Would Make Lunar Resource Production Commercially Useful?
A producer needs a customer requiring an acceptable product at a location the system can serve. The full cost of production and delivery must be assessed against supply from Earth. Repeatable operating evidence and defined procurement requirements would help determine whether a proposed system can meet that customer’s needs.
Appendix: Glossary of Key Terms
In-Situ Resource Utilization
The use of materials available where a mission operates to produce supplies for that mission or other users. In lunar exploration, it can involve converting local material into oxygen or recovering water, reducing the quantity of some supplies transported from Earth.
Beneficiation
Preparation of raw material before chemical or thermal processing. It can involve separating particles by size or concentrating a useful mineral, helping downstream equipment receive material with more consistent properties or a larger proportion of the substance being sought.
Regolith
The loose dust and fragmented rock covering a solid planetary surface. Lunar regolith provides potential construction material and contains oxygen-bearing minerals, but its abrasive particles also complicate excavation and equipment operation. Its properties differ between locations and types of terrain.
Mass Spectrometer
An instrument that identifies substances by measuring electrically charged particles according to their mass relative to their charge. In resource prospecting, it can analyze gases released from heated material, helping scientists determine which volatile substances a sample contains and in what proportions.
Volatiles
Substances that can escape as gases under relevant temperature and pressure conditions. Water is an important example in lunar exploration, although samples can contain other volatile compounds. Their behavior affects sample preservation and the design of extraction and purification equipment.
Regolith Simulant
Material made on Earth to reproduce selected properties of lunar or other planetary regolith. A simulant may reproduce chemical composition or physical behavior, but does not necessarily reproduce every characteristic. Test results must be interpreted according to the properties the chosen material represents.
Sintering
A process that bonds particles into a more consolidated material through heating, sometimes assisted by pressure or an electric field. Lunar construction research investigates whether this can turn loose regolith into useful shapes without importing large quantities of binding material from Earth.
Electrolysis
The use of electrical energy to drive a chemical reaction. Space resource applications include splitting water into hydrogen and oxygen, or releasing oxygen from minerals in suitable processing systems. Its usefulness depends on equipment performance and the availability of electrical power.
Technology Readiness Level
A scale describing how far a technology has progressed from scientific principles toward demonstrated operation. The rating applies to a defined technology and setting. It does not independently establish production scale or the financial viability of using that technology within a larger system.
