A proof-of-concept X-ray µ-Mapping Spectrometer was assembled with commercial components. The system is considered to be ~TRL 2.
Support for the CheMin mineralogical instrument during the Mars Science Laboratory (MSL'11) mission: Experiment planning, data analysis and mission operations
Wednesday, November 05 2014 - 9:23 pm, PST
This proposal is to support Dr. Philippe Sarrazin’s activities as Co-I of the CheMin mineralogical instrument that is part of the Mars Science Laboratory (MSL) rover Curiosity, during its one Mars year mission on the Mars surface. Dr. Sarrazin was a named Co-I on the original CheMin instrument proposal submitted to the MSL mission announcement of opportunity and his inclusion was validated at that time by Dr. Michael Meyer, Mars Program Scientist at NASA Headquarters. In the interval between CheMin’s selection as an MSL payload element and the launch of the MSL (Phases A-D of the instrument project), Dr. Sarrazin was supported through contracts administered directly from the Mars Program Office at the Jet Propulsion Laboratory. During Phase E of the instrument project (Mission Operations), Dr. Sarrazin’s activities will be supported through the Coop agreement described herein, administered through Ames Research Center. The duties and obligations of CheMin Co-I’s are delineated in the CheMin Experiment Operations Plan (JPL D-36918) “CheMin EOP” or “EOP” and publications listed therein. Funding for Dr. Sarrazin for the duration of Phase E, which is detailed in the CheMin EOP, has been validated by the Mars Program Office and by Dr. Michael Meyer, Mars Program Scientist at NASA Headquarters.
Hybrid powder / single-crystal X-ray diffraction instrument for planetary mineralogical analysis of unprepared samples
Wednesday, November 05 2014 - 9:18 pm, PST
We are developing a new type of X-ray diffraction (XRD) / X-ray fluorescence (XRF) planetary instrument based on a hybrid concept that allows performing both powder XRD and single crystal XRD. The main benefit of this hybrid concept is the possibility to analyze minerals with limited or no sample preparation.

The central objective of this proposal is perform uniform state-of-the-art lightcurve modeling with Kepler's list of planetary candidates (Kepler Objects of Interest or KOIs) using tested and validated algorithms. This process includes modeling of planetary transits, phase curves and providing orbital solutions. We will use Kepler-photometry and other groundbased observables to determine key planetary parameters such as the radius and mass. More importantly, we will also determine posterior probability distributions for the fitted parameters by employing state-of-the-art Markov chain Monte Carlo algorithms.

Methane Migration on a Uranus-class planet

This lab and field project will measure biogenic gas fluxes in engineered and natural microbial mats composed of anoxygenic phototrophs and anaerobic chemotrophs, such as may have existed on the early Earth prior to the advent of oxygenic photosynthesis. The goal is to characterize the biogeochemical cycling of S, H, and C in an effort to constrain the sources and sinks of gaseous biosignatures that may be relevant to the detection of life in anoxic biospheres on habitable exoplanets.

This proposal would directly investigate the global character of Pluto's atmosphere and its two-way feedbacks with N2 ice on the surface by combining a state-of-the-art three-dimensional atmospheric model with a detailed surface/subsurface thermal model.

The overall goals of the proposed Mars research are to identify locations, areas, seasons, and times-of-day within a 10x10 degree study area (greater Meridiani Planum) where/when sand-sized particle transport by the wind (aeolian saltation) has occurred (may have occurred, is probable) within the contemporary era, and to initially characterize the atmospheric and/or geologic forcing mechanism(s) that create such aeolian-effective conditions near the surface. In order to achieve these goals, the proposed work will utilize both the analysis of high-resolution orbital imagery (e.g., HiRISE, CTX, MOC-NA; including any available repeat imaging of relevant locations) and high-resolution atmospheric modeling output (mesoscale and microscale; seasonally- and diurnally-resolved 3-D winds and atmospheric state information). The proposed effort would significantly advance the detailed understanding of the dominant non-catastrophic contemporary surface erosion process on Mars.
