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 …
