Mineralogy Of Aeolian Deposits In Gale Crater, Mars: The Bagnold Dunes To Glen Torridon, Eleanor Moreland May 2021

Mineralogy Of Aeolian Deposits In Gale Crater, Mars: The Bagnold Dunes To Glen Torridon, Eleanor Moreland

Senior Honors Papers / Undergraduate Theses

We select four sand deposits along the traverse of the Curiosity rover to evaluate the spatial distribution of mineralogy and grain size. While extensive work has focused on characterizing the Bagnold Dunes in-situ and from orbit, less attention has been given to deposits south of the Vera Rubin Ridge (VRR). Overall, our results illustrate a compositional dichotomy among aeolian deposits, separated by the VRR. Initial investigations of hyperspectral data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) show differences in the long wavelength spectral features and absolute reflectance measurements for the deposit south of the Bagnold Dunes. The southern …


Fracture Networks On Mars: Preservation Of Surface And Subsurface Environments At Mawrth Vallis, Phoebe Kinzelman Aug 2019

Fracture Networks On Mars: Preservation Of Surface And Subsurface Environments At Mawrth Vallis, Phoebe Kinzelman

The Journal of Purdue Undergraduate Research

Mawrth Vallis is an outflow channel on Mars that cuts through some of the planet’s most ancient terrains, which contain many different types of fractures. The ExoMars rover mission will search for biosignatures on Mars, and this site was proposed as one of the two final candidate landing sites for the rover. A biosignature is any object that shows evidence of past or present life. Fracture networks are a high priority for the mission because they might contain minerals precipitated by fluid interaction, and these minerals could trap and preserve biosignatures, critical for our understanding of ancient processes. In this …
