A Mastcam Multispectral Investigation Of Rock Variability In Gale Crater, Mars: Implications For Alteration In The Clay-Sulfate Transition Of Mount Sharp, Alivia Eng
WWU Graduate School Collection
The Mars Science Laboratory Curiosity rover has explored over 650 m of strata since landing in 2012. After leaving Vera Rubin Ridge (VRR), the rover traversed though the phyllosilicate-rich region, Glen Torridon, and the Mg-sulfate-bearing strata that lies above it, with excursions onto the Greenheugh Pediment and Amapari Marker Band. These unique stratigraphic units were investigated using Curiosity's instrument suite which includes the Mast Camera (Mastcam) pair of multispectral imagers. Mastcam’s narrowband filters are sensitive to iron-bearing phases and some hydrated minerals. We used Mastcam spectra, in combination with chemical data from Curiosity’s CheMin, APXS and ChemCam instruments, to assess …
Martian Spectroscopy: Laboratory Calibration Of The Perseverance Rover’S Mastcam-Z And Photometric Investigation Of Mars-Analog Ferric-Coated Sand, Kristiana Lapo
WWU Graduate School Collection
The Mars 2020 rover Perseverance will search for signs of past habitability and biosignatures after landing in Jezero Crater in February 2021. Spectroscopy is a vital tool for planetary remote sensing and Perseverance is equipped with Mastcam-Z, a stereoscopic, zoom-enabled, multispectral imager that can acquire true color images with red, green, and blue (RGB) color filters, and visible- to near-infrared images with 12 narrowband science filters between 400 and 1100 nm. Mastcam-Z will provide operational support for the rover as well as directly contribute to Perseverance’s geologic investigations. Given the integral role of Mastcam-Z in the Mars 2020 mission, calibration …
Using Multispectral Imagery To Interrogate Deposition, Alteration, And Weathering Across Curiosity Rover’S Traverse In Gale Crater, Mars, Christina Seeger
Using Multispectral Imagery To Interrogate Deposition, Alteration, And Weathering Across Curiosity Rover’S Traverse In Gale Crater, Mars, Christina Seeger
WWU Graduate School Collection
Since landing in 2012, the Mars Science Laboratory (MSL) Curiosity rover has explored over 20 kilometers of Gale crater, climbing almost 400 meters in elevation. The fluvio-deltaic, lacustrine, and aeolian sediments in the crater have been well documented by Curiosity’s suite of in situ and remote science instruments. Indeed, they have traced chemical trends that track changes in lithology and diagenesis over the study area—though most instruments only sample individual rock, vein, and soil targets at a very small scale. The Mast Camera (Mastcam) has periodically acquired much larger (meter-scale) multispectral, visible to near-infrared observations of outcrops throughout this stratigraphic …
Bio-Preservation Potential Of Sediment In Eberswalde Crater, Mars, Cory Hughes
Bio-Preservation Potential Of Sediment In Eberswalde Crater, Mars, Cory Hughes
WWU Graduate School Collection
Within Eberswalde crater, Mars, is one of the most well-preserved river delta deposits identified within Mars’ rock record, and visually traceable from the deposit, is the partially-intact watershed that fed the paleo-lake that once resided within the crater basin. Aqueous alteration minerals, smectite clays and opaline silica, have been previously identified within the deposit, however the origin of those minerals is not well understood. Through analysis of topographic and hyperspectral data, we seek to ascertain the origin and provenance of these minerals to better understand their formative conditions and formation age. We will also assess Eberswalde crater’s potential as a …
