Understanding laser-induced breakdown spectroscopy (LIBS) on Mars - New approaches for quantitative elemental analysis and mineral classification

Thursday, November 06 2014 - 9:21 am, PST
We propose to study advanced spectral processing methodologies for the extraction of mineralogical information from complex geological materials, and to investigate the atmospheric-mineral matrix coupling effects under Martian environmental conditions. For this, we will make use of Washington University in St. Louis unique laboratory facilities which will allow us perform high-resolution multispectral analysis of standard samples and mixtures representative of Martian mineralogy.

Comminution of Aeolian Materials on Mars

Tuesday, November 04 2014 - 7:14 am, PST
The project will attempt to demonstrate experimentally that aeolian action on Mars leads to the production of vast quantities of silt that have an anomalous mixture of extremely well-rounded grains and extremely angular material.

Planetary Science and Exploration Studies

Monday, November 03 2014 - 11:52 pm, PST
A 4-year multidisciplinary research program supporting NASA’s Strategic Plan and Science Plan goals and objectives is proposed. The guiding theme for the proposed Science investigations is Water in the Solar System; that for the proposed Exploration work is Steps to Humans on Mars.

Mars Surface Processes, Exploration and Educational Outreach

Monday, November 03 2014 - 7:35 pm, PST
The proposal contains four broad tasks. Task 1 outlines Mars Landing Site Selection activities support for the Mars Science lab 2009 mission. Task 2 suppors HiRISE Science CoI team responsibilities as part of the Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE). Task 3 supports the PI's responsibilities for leading and developing HiRISE's Education and Public Outreach effort. Task 4 involves the continuation of PI Gulick's The Geologist's Field Assistant project.

Exploration of Planets Past, Present, and Future Habitability

Friday, October 31 2014 - 12:35 pm, PDT
With this task, we pursue our research in sedimentology related to the Mars Exploration Rover (MER) mission (mission data and terrestrial analogs), which has now entered its third extended mission and the interpretation of orbital imagery focusing on the basin deposits of the martian highlands. Our objective is to characterize and map potential life habitats from the ground and orbit.

Mapping Summertime Evolution of Ice in the North and South Poles with CRISM

Friday, October 31 2014 - 12:26 pm, PDT
We propose to use data from the CRISM visible/near infrared (VNIR) mapping spectrometer to examine the spectral changes that take place in the north and south polar caps during summer. It is well known that the residual cap in the north is composed of water ice and in the south is composed of CO2 ice, but changes within the warm season are not yet understood. This proposal will augment recent work on CRISM observations of the springtime evolution and retreat of the seasonal cap of both hemispheres: (Brown et al. 2009 for south and Brown et al 2012 for north).

Polar water ice clouds and dust aerosols seasonal mapping using CRISM EPF data

Friday, October 31 2014 - 12:09 pm, PDT
We propose to use Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) emission phase function (EPF) measurements in the Martian poles (regions poleward of 55° latitude) to map dust and water ice aerosols and surface albedos as a function of season using CRISM data.

Characterization of Martian Surface Mineralogy and Habitability

Friday, October 31 2014 - 12:04 pm, PDT
Characterization of the Martian surface via orbit and landed investigations is proposed here. We will be analyzing data collected by the Mars Reconnaissance Orbiter (MRO) that is currently in orbit at Mars. We are also performing lab analyses that provide ground truthing for the MRO-CRISM data.

Investigating the Origin of Layered Outcrops in the Mawrth Vallis Region

Friday, October 31 2014 - 11:46 am, PDT
The Mawrth Vallis region contains one of the largest outcrops of layered material, largely dominated by phyllosilicate-bearing rocks and adorned by discordant layering and unusual textures. The goal of this project is to determine the origins of these layered outcrops and test whether sedimentary processes may have contributed to their formation.
