Polarization Changes in Lunar Simulant Soil: The Role of Incident, Reflection, and Off‐Plane Angles

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Observing the polarization of the lunar regolith is essential for obtaining detailed information about the composition and characteristics of lunar soil. Observations conducted via lunar orbiters facilitate polarization measurements over wide areas; however, achieving very high‐resolution imaging requires either a large optical system or a ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Controlled Source DAS Coupling Tests: Implications for Unburied Deployment on the Moon and Earth

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Moonquake recordings are key to understanding the Moon's internal structure, yet existing data from the Apollo missions are limited. Distributed Acoustic Sensing (DAS) offers a promising alternative to conventional seismometers for future lunar seismic monitoring, particularly due to its robustness and suitability for high‐scattering ...

Laser powder-directed energy deposition of lunar highlands regolith simulant in argon and vacuum environments: Effects of atmosphere on microstructure

Additive Manufacturing Letters
Additive manufacturing (AM) of lunar regolith offers a potential pathway for in-situ resource utilization (ISRU) on the Moon, but the limited understanding of how the extreme conditions of the lunar environment influence processing approaches has limited

Binder Jetting of Lunar Regolith: Densification Optimization in Air and Vacuum, and Mechanical Performance Evaluation

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Binder jetting has emerged as a compelling approach for processing lunar regolith, as it is well‐suited for low‐energy environments and requires lower amounts of organic binder, compared to the competitive technologies. This study investigates the feasibility of binder jetting lunar regolith simulants from micrometric particles, focusing on ...

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).

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 ...
