JPL leader to speak on future of space and Earth exploration, May 8

Charles Elachi, a pioneer in the development and use of spaceborne imaging radar for scientific studies of Earth and other planets, will present a lecture at 8 p.m. Wednesday, May 8, in McDonnell Auditorium.

Elachi, who was named director of NASA's Jet Propulsion Laboratory in Pasadena, Calif., in January 2001, will speak on "Space and Earth Exploration 2010: Opportunities and Challenges."

Elachi has served in a variety of research and management positions at the lab since 1971. He is perhaps best known for his role in the development of a series of imaging radar systems for the Space Shuttle that allowed scientists to see through clouds that blanket Earth. The radar even penetrates the top layer of soil in arid regions, revealing hints of what lies below the surface.

Elachi is the author of more than 200 publications on space and planetary exploration, Earth observation from space, active microwave remote sensing, wave propagation and scattering, electromagnetic theory, lasers and integrated optics, and he holds several patents in those fields. In addition, he has written three textbooks on remote sensing.

His talk is part of the Evnin Lectures in Science and Technology for the New Millennium and is sponsored by the Council on Science and Technology , the Department of Mechanical and Aerospace Engineering and the Department of Astrophysical Sciences .
