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.

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 ...

A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...

Can plants grow on Mars and the moon: a growth experiment on Mars and moon soil simulants. [PDF]

PLoS ONE, 2014
When humans will settle on the moon or Mars they will have to eat there. Food may be flown in. An alternative could be to cultivate plants at the site itself, preferably in native soils.

Evaluating Seismic Ambient Noise Techniques for Detecting Ice‐Bearing Rocks on the Moon

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract One of the primary objectives of upcoming lunar missions is to locate ice‐bearing rocks at the South Pole. While evidence for their presence exists, the exact distribution and quantity remain uncertain. In this study, we evaluate the potential of seismic ambient noise techniques—including seismic interferometry, H/V spectral ratios ...

Additive manufacturing of physical assets by using ceramic multicomponent extra-terrestrial materials [PDF]

, 2016
Powder Bed Fusion (PBF) is a range of advanced manufacturing technologies that can fabricate three-dimensional assets directly from CAD data, on a successive layer-by-layer strategy by using thermal energy, typically from a laser source, to irradiate and

Functional Comparison of Lunar Regoliths and Their Simulants [PDF]

Journal of Aerospace Engineering, 2013
AbstractLunar regolith simulants are essential to the development of technology for human exploration of the Moon. Any equipment that will interact with the surface environment must be tested with simulant to mitigate various risks, such as unexpected mechanical abrasion, chemical interactions, or thermal failures. To reduce the greatest amount of risk,

Investigation of the Thermal Conductivity of Dry and Icy Lunar Regolith Simulants

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract This study investigates the thermal conductivity of lunar regolith simulants, both with and without the addition of ice. A novel icy regolith simulant was developed, combining microgranular water ice particles and lunar highlands simulant LHS‐1.

High-Energy Detonation Based Lunar Regolith Simulation for Resource Utilization

Aerospace
As international lunar exploration shifts from mainly understanding the Moon to equally prioritizing its utilization, the requirement for highly similar lunar regolith simulants has grown.
