Use of 3He Neutron Sensors for Planetary Penetrator Experiments

Earth and Space Science, Volume 12, Issue 6, June 2025.
Abstract This paper provides a report on a test that was carried out over 20 years ago to demonstrate that two 3He gas proportional neutron sensors could survive a high‐impact penetrator test. This test was carried out as part of a risk reduction effort for a proposed mission that would send multiple penetrators to landing locations within lunar ...

Evaluating the Depth–Age Hypothesis for the Evolution of the Lunar Regolith

The Planetary Science Journal
Lunar regolith is the fractured rock layer covering most of the lunar surface. This rock is fractured into regolith primarily by repeated meteorite impacts over eons.

The Meter‐Scale Roughness of Asteroid (101955) Bennu From the OSIRIS‐REx Laser Altimeter

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract Asteroid (101955) Bennu is a near‐Earth, potentially hazardous, rubble pile asteroid, and was the primary target of the NASA OSIRIS‐REx mission. The surface is dominated by the expression of boulders and has been heavily modified by impact cratering. Here, we analyze surface roughness, calculated using data from the OSIRIS‐REx Laser Altimeter,

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.

Integrated Seismic Refraction, Reflection, and Rayleigh Wave Imaging at Kilbourne Hole, New Mexico: Implications for Lunar Subsurface Exploration

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract Maars are volcanoes with a central crater surrounded by an ejecta ring formed through surface explosive processes from underlying magma interacting with fluids. The study of terrestrial maar volcanoes, as analogs to explosive volcanic vents on the Moon and other planets, can improve our understanding of planetary volcanism and evolution.

Optimal Radio Window for the Detection of Ultra-High-Energy Cosmic Rays and Neutrinos off the Moon [PDF]

, 2005
When high-energy cosmic rays impinge on a dense dielectric medium, radio waves are produced through the Askaryan effect. We show that at wavelengths comparable to the length of the shower produced by an Ultra-High Energy cosmic ray or neutrino, radio ...

Review and Evaluation of Ceramic‐Stabilized Iron Oxides for Use as Energy Storage Based on Iron‐Steam Process

steel research international, Volume 96, Issue 5, May 2025.
The iron‐steam process is an emerging technology for hydrogen production and storage, gaining attention due to its potential for sustainability and cost‐effectiveness. Developing an inexpensive and stable contact mass with maximum oxygen capacity while maintaining suitable reaction kinetics and chemical yields remains a challenge.
