Ejecta Stratigraphy Modeling of the NASA/VIPER Exploration Zone at Mons Mouton Near the Lunar South Pole 

Christopher, Hephzibah (2023-04-24)
Permanently shadowed regions (PSRs) within some lunar polar craters host water ice and other volatiles delivered by sources such as asteroids, comets, interior degassing, and solar wind sputtering because of their frigid ...

Impact Induced Landslides as a Mechanism for Diffusive Degradation of Complex Craters found Near the Lunar Southern Pole 

Talkington, Catherine (2022-05-05)  ETD File Embargoed
Throughout its history, the Moon’s surface has experienced numerous impact cratering events. Such events have degraded the surface through various processes. Processes include ejecta blanketing, overlapping (cookie cutting), ...

Mercury Impact Ejecta’s Contribution to its Own Meteoroid Population 

Jackson, Pierce (2022-04-21)
Mercury’s position in the inner Solar System and lack of an atmosphere subjects it to the greatest mean velocity impacts of the inner Solar System. Ejecta launched at speeds less than 4.25 km/s are retained by the planet ...

Numerical approaches to investigate small bodies’ properties in their structure and surface with case studies 

Kim, Yaeji (2023-04-27)
Asteroids, comets, and Kuiper-belt objects (aka. Small bodies) can tell us essential information to understand their evolutionary history and advance the history of our solar system. Since the currently available data on ...

Surficial Investigations of Hargraves Crater and Siloe Patera, Mars 

Emran, Al (2019-07-15)
This study investigates Hargraves crater and Siloe Patera of Mars. Individual barchan and barchanoids dunes in Hargraves were almost accurately identified using a semi-automated object-based image analysis technique. The ...
