Spark plasma sintering and optical characterization of lunar regolith simulant

Acta Astronautica, 2022
Preprint version. Paper submitted to a journal on January 05, 2022.. Under review. Abstract To satisfy the essential needs, including energy requirements, for human and robotic space explorations on planetary objects like Moon, Mars and asteroids, the proper exploitation of resources available in-situ represents a crucial issue.

The Effect of Tip Design on Technological Performance During the Exploration of Earth, Lunar, and Martian Soil Environments

Journal of Field Robotics, Volume 43, Issue 1, Page 387-408, January 2026.
ABSTRACT This paper investigates the penetration performance of soil‐burrowing probes with different tip designs during shallow‐depth penetration in various media, including terrestrial soils (Hostun sand) and well‐characterized planetary soil simulants (LHS‐1 Lunar regolith simulant and MGS‐1 Martian regolith simulant).

Planetary Soil Simulant Characterisation: NU-LHT-2M Study Case to Support Oxygen Extraction Lab Tests with a Low-Temperature Carbothermal Process

Aerospace
Since the landing on the lunar surface, the lunar regolith has begun to interact in different ways with landed elements, such as the wheels of a rover, astronaut suits, drills, and plants for extracting oxygen or manufacturing objects.

Performance of Lunar Regolith Shield under Meteoroid Impact: Uncertainties of a Numerical Prediction

Applied Sciences, 2022
The protection of the future lunar base from radiation, thermal stresses and impacts of meteoroids can be achieved by several options, generally consisting in a shielding system, made of either regolith or combined materials.

Mineral Weathering Experiments for Terrestrial Planetary Analogs in a Continuous‐Flow Reactor

Geofluids, Volume 2026, Issue 1, 2026.
Understanding the groundwater environments for ancient Mars and other terrestrial bodies is of great interest for evaluating their habitability. Here, we experimentally tested simulated aqueous alterations of two Mars simulants (variants of MGS‐1) using a continuous‐flow packed bed reactor, reacting with three ionic simulated groundwater analog ...

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Experimental Evaluation of Lunar Regolith Settlement Caused by Ice Extraction

Aerospace
Water resources are essential to human exploration in deep space or the establishment of long-term lunar habitation. Ice discovered on the Moon may be useful in future missions to the lunar surface, necessitating the consideration of in situ resource ...

Verification of a virtual lunar regolith simulant

Frontiers in Space Technologies
Introduction: Physical regolith simulants are valuable tools for developing In-Situ Resource Utilisation hardware. However, using virtual models of regolith instead can reduce costs, limit exposure to hazardous materials, and offer a practical method of testing the effects of reduced gravity.Methods: We verify a virtual model of regolith as ...

The Influence of Space Weathering on the Far‐Ultraviolet Reflectance of Apollo‐Era Soils

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract Building on our previous studies of the far‐ultraviolet (FUV) reflectance of Apollo soil 10084 and lunar soil simulants JSC‐1A and LMS‐1 (Gimar et al., 2022, https://doi.org/10.1029/2022je007508; Raut et al., 2018, https://doi.org/10.1029/2018je005567), we present new FUV results for Apollo soils 68501 and 71061. Heavily weathered soils (68501,

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, Volume 27, Issue 22, November 2025.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...
