The proposed project aims to increase the TRL of the Microwave Heating Demonstrator (MHD) payload concept developed for investigating the potential of the microwave heating method to fabricate construction components and extract valuable resources such as oxygen and water from lunar regolith. Because the development is timely and essential to support ESA’s lunar ISRU-derived mission activities, the initial concept and design of the MHD payload were successfully developed with support from the UKSA’s NSTP GEI (GEI2-037) and Pathfinder (PF3-090) funding, and ESA’s Off-Earth Manufacturing and Construction Campaign (4000133998/21/NL/GLC). Therefore, as a follow-on of the Pathfinder project, this Space Exploration Technology grant proposal aims to increase the TRL of the MHD subsystems. The main objectives of this project are to: (i) develop a microwave generator (MWG) hardware unit based on solid-state amplification capable of delivering 250 W of output power with 50 % of power-added efficiency (PAE), (ii) develop a concept of an oxygen and water extraction subsystem and upgrade the mass spectrometer subsystem accordingly, (iii) develop a complete packaging CAD design of the MHD payload with the update of the above subsystems developed in this project, and (iv) exploit the technological advancements arising from this project to place the UK industry at the forefront of lunar ISRU missions such as ESA’s EL3 and NASA’s Commercial Lunar Payload Services (CLPS) program. |

For an extended stay on the Moon, humans require habitation with substantial protection from space radiation and micrometeorites. The lunar regolith is a readily available resource in-situ, which could be thermally treated to extract oxygen and water as well as build lunar surface elements, e.g., lunar habitats, landing pad and path using 3D printing techniques. Due to the volumetric heating characteristic intrinsic to microwave heating, it is a much more efficient process than solar or laser sintering for large-scale manufacturing and construction. Our proof of concept experiment has demonstrated that microwave energy couples efficiently with lunar simulants and can readily heat it above the melting temperature. However, testing with lunar simulants cannot fulfil some missing information on microwave heating of lunar regolith, which includes the effects of nanophase iron and highly electrostatic and irregular particle shapes under the real lunar environment, i.e. vacuum and microgravity. Therefore, we aim to develop flight hardware of MARVEL (Microwave heating Apparatus of lunar Regolith for Variant Experiments of Lunar ISRU) as a payload for future ESA lunar ISRU missions. MARVEL will (i) collect and compact three samples (25~50g); (ii) heat the samples with 250 W of input power for 60 minutes; and (iii) measure the temperature and volatile release profile every second until it is cooled down to ambient temperature; to demonstrate the potential of microwave heating for construction and oxygen/water extraction. The ESA’s ISRU demonstrator mission includes a core payload to demonstrate oxygen extraction from lunar soils and secondary payloads demonstrating other aspects of lunar ISRU. Our proposed MARVEL payload could potentially address both these challenges with a unique and enabling technology for Europe. The initial concept of MARVEL at TRL 2, submitted to the ESA RFI of Lunar ISRU Demonstration Platform in December 2018, has made more progress with new consortium members. With the success of this project, we will (i) develop a model of microwave heating behaviour of lunar regolith under lunar conditions; and (ii) establish crucial criteria for developing a microwave heating-based fabrication method, including 3D Printing. |

Humans are explorers, and the Moon is expected to play a vital role in our endeavour to expand our presence into space. However, a sustainable and affordable exploration of the Solar System cannot rely solely on Earth’s resources and must use materials obtained and processed locally. The current road map agreed upon by several international space agencies envisages a long-duration presence on the Moon by 2028, initiated through the Lunar Orbital Platform Gateway and supported by commercial service providers. A key aim of this road map is to enable development of In-Situ Resource Utilisation (ISRU) to minimise dependency on transporting all resources from Earth. ISRU is a rapidly growing field in Europe as evidenced by recent ISRU workshop in 2019, organised by ESA with over 350 participants from academia and industry. Water, required for life support and propellant, has been identified as the primary resource. However, for an extended stay on the Moon, humans will require habitats with substantial shielding from radiation and micrometeorites damage. Thus, ESA is planning ISRU demonstrator missions by mid to late 2020s, with a core payload provided by industry to demonstrate oxygen extraction from lunar regolith (soil) as well as secondary payloads for demonstrating other aspects of lunar ISRU. For example, lunar regolith could be thermally treated to extract resources and build an outer habitat shell using additive manufacturing techniques (a.k.a. 3D printing) by robots. Proof of concept experiments have demonstrated that microwaves couple efficiently with lunar regolith and sinter/melt it to build 3D structures and enable resource extraction. The Open University (OU) has an extensive ongoing programme of lunar research, including a rich heritage in spacecraft instrumentation, e.g., Ptolemy and the ProsSPA instruments, of which the latter will perform first ISRU demonstration of producing water on the Moon through reduction of regolith using hydrogen. The OU has also recently invested in a custom-designed microwave instrument to evaluate the heating of planetary materials under vacuum; progressing microwave heating experiments from traditional microwaves in the air to a controllable microwave heating in a simulated space environment. Added Value Solutions UK Ltd. (AVS) designs bespoke solutions for space science markets and are developing thrusters using microwave generators designed by VIPER RF, a microwave design consultancy. Thus, the OU has initiated a collaborative project MARVEL (Microwave heating Apparatus for Regolith Variant Experiments for Lunar ISRU) with AVS and VIPER to prepare the groundwork for the UK to lead development of a Microwave Heating Demonstrator (MHD) payload on future missions to the Moon with the flight hardware being developed and built in the UK. The initial concept development of the MHD payload was successfully completed with support from UKSA’s NSTP GEI funding. As a follow-up of the GEI project, this NSTP Pathfinder grant will allow the consortium to develop a complete (including design) concept of the MHD payload. The main objectives of this project are to: (i) develop the detailed features and functional integration of the microwave cavity design, (ii) evaluate the cavity design through computational simulation, and lab-based experiment using the existing bespoke microwave heating system with specific parameters for the MHD payload, (iii) devise a realistic concept and analyse the requirement for developing 1 kW solid-state microwave generator, which can be included in the MHD payload, and (iv) develop a robust payload concept of MHD, and exploit the technological advancements arising from this project to place the UK industry at the forefront of lunar ISRU missions such as ESA’s ISRU demonstrator mission and NASA’s Commercial Lunar Payload Services (CLPS) program. The successful completion of the proposed project will increase the TRL of the MHD payload from 2 to 3/4. |

Sustainable, affordable exploration of the solar system cannot rely solely on Earth’s resources and must use materials obtained and processed locally. The current road maps of international space agencies envisage a long-term presence on the Moon by 2028. Central to this is the development of In-Situ Resource Utilisation (ISRU) to offset the need to transport all materials from Earth. For an extended stay on the Moon, humans will require habitation with substantial shielding for protection from radiation and micrometeorites. Lunar regolith (soil) is a readily available in-situ resource which could be thermally treated to build structures using additive manufacturing techniques by robots. Proof of concept experiments have demonstrated that microwaves couple efficiently with lunar regolith, hence microwaves could be an efficient mechanism to sinter/melt lunar regolith to build 3D structures and enable the extraction of volatiles. MARVEL (Microwave heating Apparatus of lunar Regolith for Variant Experiments of Lunar ISRU) aims to establish the foundation to develop a Microwave Heating Demonstrator (MHD) for ISRU experimentation on a future lunar mission. This will be achieved by formulating a conceptual design and initiating UK-based collaboration between academia and industry, with the goal of enabling UK leadership and design of an MHD payload on future missions to the Moon, such as ESA’s demonstrator mission ‘HERACLES’ or NASA’s CLPS (Commercial Lunar Payload Services) program, and indigenously developed flight hardware. |
