Energy-efficient regolith compactor for surface construction

The objective of the project was to design, developed and test the compaction device Breadboard in a regolith simulant Testbed. An experimental test campaign aimed to verify that the compaction device can be successfully used to improve the surface geotechnical properties of two different regolith simulants: GreenSpar-250 analogous to lunar Highlands, and AGK-2010 analogous to lunar Mare regions.

Fused Layer Deposition of Lunar Regolith

In order to enable lunar exploration in a sustainable manner, it is necessary to develop technologies that allow the use of lunar resources in-situ. Additive manufacturing techniques are being studied for in-situ resources utilization on the Moon (e.g.: solar or laser sintering). The results of these studies, presented samples with low mechanical properties due to the formation of defects and cracks within the final product.

Off-Earth manufacturing through self-growing 3D printer

During the project activities, the authors proposed a conceptual framework, which utilizes resources available in situ through the chemical and physical processes associated with agriculture; the soil and CO2 (if present) are transformed into fibrous plant matter, harvested and finally converted into mechanical and structural components.

Moon Fibres

Institut für Textiltechnik der RWTH Aachen University (ITA) and Institute for Structural Mechanics and Lightweight Design RWTH Aachen University (SLA) have already spun MoonFibres from regolith simulant. Gradel SARL uses the xFKin3D technological process to produces ultra-lightweight structural components made of various types of fibres and resin. This technology requires less material to create parts with equal structural strength as the ones produced in traditional ways. The produced parts can be 2D or 3D parts.

Magnetic Powder as Propellant in Electrostatic Thrusters (MPEP)

The main objectives of this project were to develop a thruster prototype based on magnetic powder electrostatic propulsion and to test it in vacuum with direct thrust measurements. The aim was to check the robustness of the concept and to measure and calculate important performance parameters such as thrust and specific impulse, to allow a comparison with other thruster technologies. This project demonstrated for the first time the feasibility of electrostatic propulsion based on powder emission.

LUPIN (Lunar Lithography Manufacturing)

Nowadays, human Moon exploration, and the consequent desire to establish a permanent settlement on its surface, represents one of the most fascinating challenge to face. The permanent presence of a human outpost very far from Earth raises the problem of the huge amount of payload required for the settlement, as well as the need of rapid and in-time supply of material and spare parts useful for all the activities carried out in-situ, including the realization of medicals tools and patient-specific back-up implants.

Smart Resource Management based on Internet of Things to support Off-Earth Manufacturing of Lunar Infrastructures (SMARTIE)

SMARTIE (Smart Resource Management based on Internet of Things to support Off-Earth Manufacturing of Lunar Infrastructures) is an ESA study to assess the requirements, architecture, hardware and software needs and costs for implementation of an Internet of Manufacturing Things (IoMT) for a lunar human base and associated infrastructure.

Effective use of Germanium

Germanium (Ge) has been identified as one of the major environmental hotspots of ESA’s space missions. As one of the critical raw materials the use of it (mainly driven by solar cells) is a major contributor to mineral resource depletion.
Today, Germanium is used as a growth template for certain solar cells. While the thickness of the Germanium on a solar cell level is extremely thin, around 140μm, actually only 10-20μm are actively being used. The rest is structural.

OMAR – On orbit manufactured spacecraft

The objective of this activity is to assess the system level and design impacts of optimising a satellite design for on-orbit manufacturing and assembly, as well as preparing it to be refurbished, reused or recycled on orbit afterwards, and to identify the technologies needed.

Analysis of space debris recycling potential to supply raw materials for construction on the Moon

As on Earth, space debris should not only be seen as a threat. Instead, the value of waste as a recycled good should be understood. On Earth, this potential is already fully recognised. The German recycling industry alone generates more revenue than the entire European space industry. Nevertheless, this treasure was never lifted in space.
