Saponite Bearing Material Excavated During the Formation of a Recent 25‐m‐Diameter Impact Crater in Southeastern Arabia Terra on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mars Reconnaissance Orbiter's Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), Context Imager (CTX), and High Resolution Imaging Science Experiment observations were analyzed for a 25‐m‐wide impact crater and associated ejecta deposits located in the dust‐covered Arabia Terra region.

Coupled Space Weathering: Nanophase Iron Formation by Micrometeoroid Impact and Solar Wind Sputtering

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the interplay between micrometeoroid impacts and solar wind irradiation is crucial for interpreting lunar surface evolution. Using reactive molecular dynamics simulations and surface binding energy (SBE) analyses, this study investigates the coupled effects of these two dominant space weathering processes on lunar regolith ...

Bio‐Inspired Swarm Robotics Design for Mine Automation

Natural Sciences, Volume 6, Issue 2, April 2026.
Ants demonstrate tandem running for cooperative haulage, and honeybees use memory‐based routes between hive and flowers. These behaviours inspire autonomous haulage robots in open‐pit mines to achieve efficient scan‐plan‐retrieve ore transport, replacing small haulage robots with large mining trucks.

Identification of small impact craters in Chang’e-4 landing areas using a new multi-scale fusion crater detection algorithm

Earth and Planetary Physics
Impact craters are important for understanding the evolution of lunar geologic and surface erosion rates, among other functions. However, the morphological characteristics of these micro impact craters are not obvious and they are numerous, resulting in ...

A Motivating Exploration on Lunar Craters and Low-Energy Dynamics in the Earth -- Moon System

, 2010
It is known that most of the craters on the surface of the Moon were created by the collision of minor bodies of the Solar System. Main Belt Asteroids, which can approach the terrestrial planets as a consequence of different types of resonance, are ...

Topographical Features of the Lunar Surface Unveiled Through Spherical Geodesic Triangulation Analysis Method of DEM Roughness at Equal Spatial Scales

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract This study introduces an innovative method using equal spherical geodesic triangulation to uniformly sample the digital elevation model (DEM) of the lunar surface, ensuring an even distribution of elevation data. Utilizing spherical spline fitting, we have proposed new methods for calculating slope angles and aspects. An equilateral triangular
