North Gale Landform and the Volcanic Sources of Sediment in Gale Crater Mars
… of a previously unidentified landform north of Gale Crater, Mars (North Gale Landform, NGL) using remotely sensed datasets and morphological mapping has determined that it is a volcanic construct that collapsed and produced a hummocky terrain deposit to the south. Volcaniclastic sediments have …

Characterization of clasts in the Glen Torridon region of Gale crater observed by the Mars Science Laboratory Curiosity Rover
… sized clasts in the Glen Torridon region of Gale crater on Mars were studied using data captured by the Mars Science Laboratory (MSL) Curiosity rover between martian days (’sols’) 2302 and 2593. The morphology and composition of clasts has the potential to reveal the nature and extent of …

Materials and Surface Processes at Gale Crater and the Moons of Mars Derived from High Spatial and Spectral Resolution Orbital Datasets
… hyperspectral data over Mt. Sharp in Gale Crater are used to generate spatially sharpened maps of the location of red crystalline hematite within the uppermost stratum of a ~6.5 km long ridge on the mound's northern flank. Emplacement of the hematite is hypothesized to result either …

Radiative Transfer in the Martian Environment: In-Situ Results from the MSL Curiosity Rover and Laboratory Experimentation on Martian Regolith and Crystalline Rock Analogs
… a suppressed planetary boundary layer within Gale Crater prior to the landing of the Mars Science Laboratory. Images from Mars allow the amount of suspended dust near the crater floor to be estimated numerically. The atmosphere within the crater is shown to be relatively dust free compared to …

Potential Microbial Processes In An Ancient Martian Environment, An Investigation Into Bio-Signature Production And Community Ecology
… characterised and compared to the palaeolake at Gale Crater, Mars. Similarities were identified in pH, temperature and Total Organic Carbon measurements, as well as potential bioessential element availability (based on comparative mineralogy of the two sites). The microbial community at the River …

Cloud Observations from the Mars Science Laboratory Mission: Seasonal Variability, Scattering Phase Function, and Validation of Optical Depths using Lidar Measurements of Terrestrial Cirrus Clouds
… the cloud activity above its landing site, Gale Crater. Over the course of two Martian years of operations (LS = 160 of MY 31 to LS = 160 of MY 33), over 500 cloud imaging sequences have been returned to Earth, revealing tenuous clouds that form predominantly in the autumn and winter …

Laser induced breakdown spectroscopy of martian breccia Northwest Africa 7034: comparison with Mars Science Laboratory results
… to determine compositions of rocks shot in Gale crater, Mars, from a distance of 1.56-7 meters. At the same time, martian breccia meteorite Northwest Africa (NWA) 7034 was analyzed with the ChemCam engineering model laboratory LIBS instrument at Los Alamos National Laboratory (LANL) at a 1.6 …

Analyzing geological materials under martian conditions using laser-induced breakdown spectroscopy : plasma fundamentals, sample classification, and trace element quanitification
… deployment of ChemCam to the surface of Mars at Gale crater onboard the Mars Science Laboratory (MSL) rover, Curiosity. ChemCam consists of a LIBS instrument and a high resolution micro-imager (RMI) and is the first extraterrestrial application for LIBS. While the state of LIBS research is …

Experiments on biomarker preservation
… the Sample Analysis at Mars (SAM) instrument in Gale Crater. The objective of this dissertation is to investigate the biological and early diagenetic transformation of organic matter within macrofossils and analog experiments to elucidate those processes, biotic or abiotic, which determine …

Differentiation in impact melt sheets as a mechanism to produce evolved magmas on Mars
… exhumed rock samples. Some rocks observed in Gale crater are enriched in alkalis (up to 14 wt% Na<sub>2</sub>O + K<sub>2</sub>O) and silica (up to 67 wt% SiO<sub>2</sub>) with low (< 5wt%) MgO. This alkaline differentiation trend has previously been attributed to fractional crystallization of …

An Approach to Modelling Ice Deposition Across the Solar System
… evolution of Mt. Sharp (Aeolis Mons) in Gale Crater, where observations by the Mars Science Laboratory Curiosity rover reveal bedrock features resembling terrestrial glacial landforms. Using MIDAS, three-dimensional flow of cold-based, debris-free glaciers were modelled to examine the …
