“Development of Techniques for, and the Analysis of, Biogeochemical Sample”

NNA04CK54A

This work will support the analysis of samples and the development of techniques to analyze samples for NASA objectives. It covers two main thrusts. The development of techniques and data for the analysis of samples of astrobiological interests, from samples returns, to analysis of exogenous materials, to the detection of life and proteins, to the detection of microbial activity in extreme environments. The other thrust is to support the characterization of biogeological materials to better understand early life on Earth, its context, how it impacted the planet, and how it evolved. This will involve both the analysis of biogeological samples collected in field and also samples produced by abiotic reactions (as a benchmark to compare samples of suspected biogenic origin against).
