In order for off-Earth top surface structures built from regolith to protect astronauts from radiation, they need to be several metres thick. With support from European Space Agency (ESA) and Vertico, the Technical University Delft (TUD) advanced research into constructing habitats in empty lava tubes on Mars in order to create subsurface habitats. By building below ground level not only natural protection from radiation is achieved but also thermal insulation because the temperature below ground is more stable.

Motivation: This study aimed to develop promising robotic fabrication methodologies for a fibre-based in-situ robotic fabrication process, for application in a lunar habitat as an alternative to existing additive manufacturing methodologies. Previous work has verified that fibre composite fabrication processes are capable of a high degree of automation and structural performance.

The contract was part of the broader framework of two ESA-led mission study teams performing parallel and independent activities to establish the mission concept, considering the ISRU payload (Segment 1), the delivery service (lander, Segment 2) and the communication service (Segment 3).
In this context the scope of the OHB Italia contract activities was related to defining the ISRU Payload.

Solar System bodies – including the Moon and Near-Earth Objects (NEOs) – contain a rich diversity of materials such as metals and volatiles that could be used as energy sources and as means to sustain human life, as humankind ventures deeper into space. Space agencies worldwide are considering such resources as potential raw materials for space infrastructure development, based on recent technological advances related to space in-situ manufacturing.

The main aspect of this study is to investigate the feasibility of the mission concept and the demonstration of the economic viability of a commercial payload delivery service to the Moon, as well as demonstrating the production of water/or oxygen with materials from the Moon. The study considered a payload delivery service that would be an end-to end service from Earth to a targeted location on the Moon, launched not later than 2025.

Several studies have addressed the building of a lunar base either under ESA or other space agencies and entities. These studies have looked at conceptual designs, often of one specific element of the base, while most of the requirements are not adequately or not at all taken into consideration.

The study and exploitation of In Situ Resource Utilisation (ISRU) technologies (with an initial focus on the Moon) are stimulating an increasing interest in the international community, both at Agency and industry levels, in view of and in preparation for future crewed exploration missions and in terms of scientific and societal long-term benefits.
Thales Alenia Space
ALCHEMIST is a payload design created in order to produce water from lunar regolith so as to demonstrate the end-to-end process of hydrogen reduction of FeO on the lunar surface.
Space Applications
The ISRU-DM mission aims to perform the first demonstration of ISRU on the Moon, via the production of water or oxygen from raw lunar material (i.e. regolith, ice etc.) At Agency-level a phase-0 level study was also performed to understand the technical and programmatic feasibility of undertaking the ISRU-DM mission via the provision of commercial services from industry.
