Evaluation of simulated space weathering-based meteorite alteration and potential influence on mechanical deformation of rubble pile asteroids

Frontiers in Astronomy and Space Sciences
Asteroids with the potential to impact Earth have become a significant focus of scientific research and applied space technology. These bodies are expected to be key targets for mitigation actions and space mining activities in the coming decades ...

Thermal Segregation and Reddening in Europa's Double Ridges

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...

Rotationally Resolved Near-infrared Spectroscopy of Three Large Eurybates Family Members

The Planetary Science Journal
The Eurybates family is the largest collisional family in the Jupiter Trojan population. Previous visible spectroscopy of asteroid (3548) Eurybates has shown potential surface heterogeneity due to rotation of the asteroid.

Spectral properties of near-Earth and Mars-crossing asteroids using Sloan photometry

, 2016
The nature and origin of the asteroids orbiting in near-Earth space, including those on a potentially hazardous trajectory, is of both scientific interest and practical importance.

Archives of impact: The politics of craters on Earth

Geographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Main-Belt Comet P/2012 T1 (PANSTARRS)

, 2013
We present initial results from observations and numerical analyses aimed at characterizing main-belt comet P/2012 T1 (PANSTARRS). Optical monitoring observations were made between October 2012 and February 2013 using the University of Hawaii 2.2 m ...

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 ...

The taxonomic distribution of asteroids from multi-filter all-sky photometric surveys

, 2013
The distribution of asteroids across the Main Belt has been studied for decades to understand the compositional distribution and what that tells us about the formation and evolution of our solar system.
