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

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

Journal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Biomining of lunar regolith simulant EAC-1 A with the fungus Penicillium simplicissimum

Fungal Biology and Biotechnology
Background On a future lunar habitat, acquiring needed resources in situ will inevitably come from the Lunar regolith. Biomining, i.e. the use of microorganisms to extract metals from the regolith, is sustainable and energy-efficient, making it highly ...

Accumulation of Dust on a Surface and the Subsequent Formation of Compact Aggregate Piles

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract Dust aggregation is a prominent topic in space physics, yet the accumulation of dust on surfaces in airless environments remains poorly understood. It is commonly assumed that, during the initial stages of dust deposition, particles spread uniformly to form a monolayer.

Analysis of four Apollo 16 double drive tubes using QEMSCAN® mapping techniques: Implications for sampling the lunar regolith in highland terrains

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2504-2523, October 2025.
Abstract The lunar regolith contains a rich history of Solar System impact events and solar activity. Many future missions will land in the south polar region of the Moon, a heavily impact cratered highland terrain, similar to the Apollo 16 landing site.

Spirulina supported plant growth in regolith simulants and elevated levels of CO2

Frontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

Viscosity measurements of selected lunar regolith simulants

American Mineralogist
Abstract In the context of evaluating lunar construction options, this study focuses on characterizing the viscosities and glass transition properties of lunar regolith simulants to support the development of additive manufacturing processes using molten regolith. Employing the modular TUBS lunar regolith simulant system, we measured the

Discovery of a Lunar Cold Spot at Apollo 16's South Ray Crater

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Lunar cold spots are extensive, ray‐like regions of reduced nighttime temperature surrounding young impact craters. Using improved Diviner temperature maps, we identify a faint cold spot surrounding South Ray crater at the Apollo 16 landing site.
