Morphologic Mapping Of Lunar Impact Basins, Zachary R. Morse

Electronic Thesis and Dissertation Repository

Modern high-resolution remote sensing datasets for the Moon provide a detailed view of the lunar surface and its features. This thesis uses visible, compositional, and topographic data to create the most detailed geomorphological maps to date of portions of three lunar impact structures: Orientale Basin, Tsiolkovsky Crater, and Schrödinger Basin, which are three of the best-preserved impact structures on the lunar farside.

This thesis discusses the mapping and analysis of seven distinct ejecta facies around Orientale, nine distinct facies in and around Tsiolkovsky, and twelve units of surface materials in the central Schrödinger Basin region. This analysis utilized 100 m/pixel …

Impact Craters On Titan: Finalizing Titan's Crater Population, Joshua E. Hedgepeth

Electronic Thesis and Dissertation Repository

Titan is one of the most dynamic moons in the solar system. It is smaller than Earth and much colder, yet Titan is eerily similar to Earth, with rivers, rain, and seas, as well as sand seas that wrap around the equator. However, the rivers are made of hydrocarbons rather than water and the sand made of organics rather rock. We can use Titan’s impact craters to study how these processes modify the surface by comparing the craters depths, diameters and rim heights of Titan’s craters with fresh craters. Therefore, we have used the complete data set from NASA’s Cassini …
