Dynamic Behavior of an Ordinary Chondrite: the Effects of Microstructure on Strength, Failure and Fragmentation
Download2015
Plescia, Jeffrey, Ramesh, K.T., Hogan, James, Kimberley, Jamie, Hazeli, Kavan
Knowledge of the relationships between microstructure, stress-state and failure mechanisms is important in the development and validation of numerical models simulating large-scale impact events. In this study, we investigate the effects of microstructural constituent phases and defects on the...

The Prebiotic Synthesis of Soluble Organic Matter in Carbonaceous Chondrites and the Influence of Asteroidal Aqueous Alteration
DownloadSpring 2018
Carbonaceous chondrite meteorites are derived from primitive asteroids in the solar system and often contain prebiotic organic compounds including amino acids, carboxylic acids, nucleobases, and smaller precursor molecules. These soluble organic compounds, synthesized via non-biological chemical...

Tracing Organic Contamination from Collection to Curation: Contamination Mitigation of Meteorites and Implications for Advanced Curation Methods of Astromaterials
DownloadFall 2022
Meteorites are the most primitive materials in the solar system and can provide important information about the early earth, planetary processes, and possibly yield insights to the building blocks of life. All meteoritic astromaterials are exposed to both organic compound and microbial...
