Experimental Investigation of Soil Adsorption Effects on Water Migration in Simulated Lunar Conditions

open access: yesThe Planetary Science Journal
Adsorption is a key mechanism governing water vapor diffusion in lunar regolith. To investigate this process, we conducted experiments under simulated lunar conditions—Knudsen diffusion conditions—using three soil types with varying water vapor ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

The Composition and Stratigraphy of the Chang’e-6 Landing Mare

open access: yesThe Planetary Science Journal
China’s Chang’e-6 (CE-6) mission returned lunar samples from the southern mare in the Apollo basin formed in the prominent South Pole–Aitken basin. The basic geological context of the landing mare has been well resolved.

In Situ Measurements of Thermal Environment on the Moon's Surface Revealed by the Chang'E-4 And Chang'E-5 Missions

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The thermal environment of the lunar surface is of crucial importance for the lander thermal design and the interpretation of scientific data. Clarifying the radiative sources and intensity on the outer surface of the lander is one of the key aspects of ...

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Large-scale Roughness Properties of the Lunar North and South Polar Regions as Measured by the Lunar Orbiter Laser Altimeter (LOLA)

open access: yesThe Planetary Science Journal
The lunar polar regions are high-priority targets for scientific investigation and exploration. To aid these endeavors, we produced enhanced altimetry data from the Lunar Orbiter Laser Altimeter for the north polar region, from which we computed new maps

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Solar Activity Dependence of the Dayside Lunar Surface Potential in the Terrestrial Magnetotail

open access: yesGeophysical Research Letters
On the dayside of the Moon, the surface potential is primarily determined by (a) photoelectron emission by solar radiation and (b) the ambient plasma environment.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Simulations on Levitation and Spatial Distribution of Charged Dust on the Moon Surface

open access: yesThe Planetary Science Journal
The levitation of charged dust, which may cause serious hazards to astronauts and lunar rovers, has been one of the most significant challenges in lunar exploration.
