TITLE: Science and Exploration of the Moon, Near Earth Asteroids, the Moons of Mars enabled by the Remote In Situ and Synchrotron Studies for Science and Exploration (RIS4E) SSERVI team.

SPEAKER: Timothy Glotch, Stony Brook University

ABSTRACT: The Remote, In Situ, and Synchrotron Studies for Science and Exploration (RIS4E) team is one of nine nodes of NASA’s new Solar System Exploration and Research Virtual Institute. Our team is addressing key aspects of the science and exploration of the Moon, Near Earth Asteroids, Phobos, and Deimos. Using a comprehensive approach to better understand the spectral data of samples and surfaces, how we will one day safely explore those surfaces, and in turn maximize our measurements of all samples, especially small, precious returned samples, RIS4E will produce a wealth of information and a team of well-trained next generation scientists. This talk will provide an overview of the five-year RIS4E effort is divided into four main research themes and support of other SSERVI objectives.

These themes are:

1. Preparation for Exploration: Enabling Quantitative Remote Geochemical Analysis of Airless Bodies. The RIS4E team is engaging in studies of remote sensing targets of opportunity, and experimental and theoretical studies to optimize the interpretation of remote sensing data sets, including experimental space weathering studies, simulated lunar/asteroid environment spectroscopic measurements and tests of advanced spectral unmixing techniques.

2. Maximizing Exploration Opportunities: Development of Field Methods for Human Exploration. Science-motivated field work is helping us evaluate the role of handheld and portable field instruments for future human exploration, enabling rapid, low-risk, comprehensive, and quantitative assessments of the local geology and regolith materials.

3. Protecting our Explorers: Understanding How Planetary Surface Environments Impact Human Health. Future astronauts will be exposed to harsh environments with potentially harmful but unknown health effects. The RIS4E team is performing experiments to determine the reactivity and toxicity of lunar analog materials, as well as lunar and chondritic samples.

4. Maximizing Science from Returned Samples: Advanced Synchrotron and STEM Analysis of Lunar and Primitive Materials. The National Synchrotron Light Source II at Brookhaven National Laboratory will be open to conduct experiments in the fall of 2014. This next-generation light source will provide unparalleled chemical and mineralogical analysis of precious lunar and primitive materials, which the RIS4E team is taking advantage of to tightly constrain the oxygen fugacity of the early Solar System.

SPEAKER BIO: Timothy Glotch is an Associate Professor in the Department of Geosciences at Stony Brook University, where he has been since 2007. He completed his Ph.D. in Geosciences at Arizona State University in 2004 and was a postdoc at Caltech from 2005-2007. His research is focused on using laboratory spectroscopic techniques and sophisticated light scattering models to enable more quantitative interpretation of spectroscopic data sets. This work includes using laboratory visible/near-infrared reflectance, thermal infrared emission, and Raman spectroscopies, both on remote sensing platforms and in the laboratory, to determine the composition of geologic materials on the surfaces of the Moon, asteroids, Mars, and its moons. He has received NASA group achievement awards for his work with the Odyssey THEMIS and MER Mini-TES instruments that have flown to Mars and the Lunar Reconnaissance Orbiter Diviner Lunar Radiometer Experiment. He is a Co-Investigator on Diviner, which has been orbiting the Moon since 2009. In 2012, he was awarded the National Science Foundation Early Career Award.
