Categorization of Spatial and Temporal Ejecta Outcomes in Binary Systems Based on Variations of the Didymos System

open access: yesThe Planetary Science Journal
With the increasing number of binary asteroid systems being discovered, ejecta studies must expand from solely investigating single-body systems to modeling more complex multiple-body systems. For example, the Double Asteroid Redirection Test provides an

Space Weathering Age of Itokawa and Eros by Machine Learning

open access: yesThe 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

open access: yesThe 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

open access: yesThe 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,

3 μm Phase Curves of Main-belt Asteroids from NEOWISE Photometry

open access: yesThe Planetary Science Journal
The shapes of asteroid phase curves are influenced by the physical properties of asteroid surfaces. The variation of an asteroid’s brightness as a function of the solar phase angle can tell us about surface properties such as grain size distribution ...

Methods for Experimental Planetary Geology in Reduced-gravity Parabolic Flight: A Case Study of Researching Impact Crater Ejecta

open access: yesThe Planetary Science Journal
Geologists have long conducted laboratory experiments to offer a controlled environment for understanding processes that occur in nature and linking those processes with natural geologic landforms.

Unusual Space Weathering on a CE-5 Metal Grain Indicates Deceptive Surface Signatures of M-type Asteroids

open access: yesThe Astrophysical Journal Letters
M-type asteroids are historically thought to be exposed metallic cores of differentiated planets with a composition dominated by pure iron and nickel. However, recent spectral and radar observations reveal an insufficient number of M-type asteroids in ...
