Asteroid Surface Weathering Inspired Optimization

This paper proposes a heuristic optimization algorithm based on asteroid surface weathering processes, named ASWO-I (Asteroid Surface Weathering Inspired Optimization). The algorithm simulates the physical and chemical changes on an asteroid's surface caused by solar wind bombardment, micrometeorite impacts, and spectral degradation, mapping these ...

The structural and spectroscopic effects of space weathering of C-type asteroid regolith documented by Ryugu sample A0112.

Fragments of the near-Earth C-type asteroid 162173 Ryugu were brought back to Earth as part of JAXA’s Hayabusa2 sample return mission (e.g., [1,2]).
