Article
Full-text available
The authors demonstrated the feasibility of sintering lunar regolith layer-by-layer solely using concentrated sunlight. First trials using actual concentrated sunlight led to an inhomogeneous sintering of individual layers of lunar regolith simulant, due to the significant flux density variations caused by atmospheric fluctuations. Tests focusing X...
Article
Lunar regolith simulant is exposed to a fast neutron flux of a spallation source. The samples consisted of a set of as-received, traditionally sintered, and solar sintered JSC-2A lunar regolith simulant. Aluminium samples were also irradiated for comparison. The ChipIr beamline of the ISIS neutron and muon source was used to provide a flux of atmos...
Article
As the utilisation of materials from the Moon, Mars, and asteroids is once again under the spotlight with the publication of a space resources strategy in Europe, and the preparation of lunar surface missions in the US, it is crucial to understand the past implementation failures of In-Situ Resource Utilisation (ISRU) in mission architectures. Goin...
Article
Full-text available
Extraction of oxygen from lunar soil is key to the sustainability of human and robotic operations on the Moon and would open the path to in-space refuelling with space resources. This work investigates reducing the temperature of the electrochemical FFC process, by changing the salt from pure CaCl2 to eutectic mixtures with KCl, NaCl and LiCl. Init...

Since the early 2010s, the European Space Agency (ESA) has increased its activities on developing in-situ manufacturing solutions, to overcome the limitations related to fairing size, launch mass capabilities or logistic missions cost and complexity. Technology development activities have addressed promising processes for manufacturing in space, as...

The European Astronaut Centre (EAC) is currently constructing the European Lunar Exploration Laboratory (LUNA), a large training and operations facility to be located adjacent to EAC at the DLR (German Aerospace Centre) campus in Cologne, Germany. With an estimated representative lunar testbed area of approximately 660 m2, a large volume of lunar r...

Additive manufacturing (AM) is one of the most promising techniques for on-site manufacturing on extraterrestrial bodies. In this investigation, layerwise solar sintering under ambient and vacuum conditions targeting lunar exploration and a moon base was studied. A solar simulator was used in order to enable AM of interlockable building elements ou...

Space Resource Utilisation (SRU) or In Situ Resource Utilisation (ISRU) is the use of natural resources from the Moon, Mars and other bodies for use in situ or elsewhere in the Solar System. The implementation of SRU technologies will provide the breakthrough for humankind to explore further into space. A range of extraction processes to produce us...
Article
The capability to manufacture items in space is an exploration enabling advancement, and will be crucial for sustainable human exploration as we progress beyond Earth orbit. The extrusion based Fused Filament Fabrication (FFF) method using thermoplastics represents a robust and simple methodology applicable to printing parts for both current and fu...

Conference Paper
Full-text available
Future missions to the Moon will require the utilization of the local resources in order to make them affordable. The EU-funded RegoLight project advances existing 3D printing technologies and methodologies for the purpose of shaping lunar regolith, a readily available resource on the Moons surface, through the means of concentrated sunlight that s...
Conference Paper
Full-text available
In the last few years, different concepts have been investigated in the context of building human-tended bases in extra-terrestrial environments through ISRU. NASA has conducted a 3D printed habitat challenge in 2015, which put international focus on the topic. Amongst microwave sintering, contour crafting and other Additive Manufacturing (AM) tech...
Article
Full-text available
The authors investigate mechanical properties of sintered lunar regolith. Using JSC-1A and DNA lunar simulants, they study the influence of changes in glass content, main plagioclase series, and ilmenite content on a defined sintering process and on the mechanical properties of resulting sintered samples. Ilmenite addition up to 20 wt% of the regol...
