Space Weathering Age of Itokawa and Eros by Machine Learning

The Planetary Science Journal
Near-Earth asteroids such as Itokawa and Eros provide valuable insights into the collisional and surface evolution of the inner solar system. As S-type asteroids, their surfaces are altered by space weathering (SW) from solar wind and micrometeorite ...

Charged Ejecta Clouds from Granular Beds after Slow Impacts

The Planetary Science Journal
Low-velocity impacts are a significant process on all planetary surfaces, from rebounding particles on asteroids to saltating grains on Earth. Due to triboelectric effects, the material involved can be charged. We carried out experiments to study the net

The Dehydration of Serpentines and Extraction of Water

The Planetary Science Journal
Some groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,

Topographic recognition of the asteroidal surface

Topographic recognition of the asteroidal surface
A stereo vision system with fisheye lens cameras is newly proposed as an onboard instrument of a future asteroid lander. The system is designed to recognize an entire landscape around the landing/touchdown point with a pair of super-wide-angle fisheye lens cameras.
