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,

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

The 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

The 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

The 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 ...
