Planetary application of Raman spectroscopy
We have been studying lunar samples (rocks & soils samples from Apollo missions), Martian samples (meteorites), and Martian analog samples byRaman spectroscopy. Through these studies, we gain knowledge of how much compositional and structural information of a mineral can be obtained by in-situ Raman measurements. We develop methods for determining mineral proportions in rocks or soils and identifying rock types. We learn how weathering and alteration affect the Raman and luminescence features of the minerals and rocks, and we collect information on the Raman characteristics of biogenic organisms and their remains. These studies are the scientific bases for in-situ planetary Raman spectroscopy. They are also part of our preparations for interpreting Raman data from future missions. In addition, we carry out Raman studies on subjects directly related to the development of mission strategy.
