What We Do "Brown Bag" Seminar Series



Date:   Monday, October 15, 2007

Location:   Building 33, conference room H114

Time:   11:45 am to 1 pm


Speaker:    Dr. Dave E. Smith

Abstract:    "From IRAD's to Proposals, to Projects, to Research, maybe"
The undertaking of science investigations has become more complex and difficult as we move to a "Project" approach. Experience in the planetary science and exploration field continues to show great opportunities for involvement in missions beyond Earth orbit but the competition is tougher insisting that we be better prepared. Hence the importance of IRAD's and well thought out proposals. I will discuss my experiences as an instrument PI on planetary missions, my experience with early preparation and the writing of proposals, the ultimate satisfaction of being selected (maybe), and finally seeing science data.

Speaker:    Dr. Dave Harding

Abstract:    "Solid Earth Science Applications of Geodetic Imaging Lidar"
High resolution mapping of the topography of the Earth's solid surface, and its change through time, has been identified by the National Academy of Sciences as a high priority need in the coming decade. These data are required to understand and model the coupled processes that shape the Earth's surface and to assess the risk posed by natural hazards, forecast their occurrence and mitigate their effects. Goddard is the unsurpassed leader in developing the technology best suited to acquire the needed data, Geodetic Imaging Lidar. Examples of the uses of Imaging Lidar data for solid Earth purposes will be illustrated, and its relevance for future planetary mapping will be described.

Speaker:    Dr. James B. Abshire

Abstract:    "Using lasers for Measuring Atmospheric Gases from Orbit"
Atmospheric gas concentrations provide important clues about processes occurring at and near the surface of the Earth and planets. The National Academy has recommended that NASA develop a new laser-based mission for Earth science to measure atmospheric CO2 concentrations from orbit to improve understanding of the carbon cycle. The are also important questions in planetary science, particularly for Mars, which can be addressed by measuring methane, water vapor, and other gases in their atmospheres from orbit. I will give an overview of our group's work in developing new types of trace gas lidar to measure a variety of gas concentrations by using wavelength tunable lasers.
