Étude des signatures aqueuses martiennes par spectroscopie infrarouge : des nuages à l'altération des régions polaires

Stcherbinine, Aurélien

Study of Martian aqueous signature through infrared spectroscopy: from clouds to polar regions alteration

On Mars, the major infrared signature of the surface consists of a broad absorption band at 3 µm. It is mainly associated with the presence of H2O molecules or –OH groups and provides insight about the presence of water ice and the hydrat…

The H Corona of Mars

Chaffin, Michael Scott

The atmosphere of every planet is surrounded by a tenuous cloud of hydrogen gas, referred to as a hydrogen corona. At Mars, a substantial fraction of the H present in the corona is moving fast enough to escape the planet's gravity, permanently removing H from the Martian atmosphere. Because this H is ultimately derived from lower atmospheric water…

Spectral Identification and Analyses of Hydrous Mineral Deposits: Implications for the Aqueous History of Aram Chaos and Melas Chasma, Mars

Liu, Yang

Orbital remote sensing data acquired from the Mars Express OMEGA and MRO CRISM instruments, in conjunction with other datasets, are used to perform detailed spectral and stratigraphic analyses with the goals of better understanding the mineralogy and aqueous history of deposits in Aram Chaos and south and southwest Melas Chasma on Mars. The Discre…

Remote sensing and terramechanics study of Mars using orbital and rover data sets

Lichtenberg, Kimberly Ann

Orbital observations, rover-based remote-sensing and in-situ observations, and terramechanics modeling can be used collaboratively to examine the interplay between material properties, scientific setting, and mobility issues facing rovers on other worlds. In this thesis, these types of observations are used concurrently to identify the surface pro…
