Development of an Elemental Micro-Mapping Instrument Concept

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

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

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.
