Douglas Isbell Headquarters, Washington, DC February 5, 1998 (Phone: 202/358-1753) Mary Hardin Jet Propulsion Laboratory, Pasadena, CA (Phone: 818/354-5011) NOTE TO EDITORS: N98-11 NEW INSIGHTS INTO ANCIENT ANGKOR BY NASA RADAR TO BE SUBJECT OF PRESS BRIEFING Radar imagery that may revolutionize archaeological understanding of the ancient Angkor complex of temples in northern Cambodia will be the subject of a NASA press briefing at 1 p.m. EST on Thursday, Feb. 12. The briefing will originate from NASA's Jet Propulsion Laboratory (JPL) in Pasadena, CA. The briefing, including supporting video material, will be broadcast live on NASA Television. Angkor is a vast complex of some 1,000 temples covering about 100 square miles of northern Cambodia, built between the 8th and 13th centuries AD. Today, much of Angkor is inaccessible or hidden beneath a dense forest canopy. The latest research findings were made possible by the Airborne Synthetic Aperture Radar (AIRSAR) developed by JPL, an Earth science instrument that can reveal features hidden from visual systems. Participants in the briefing will include: · Dr. Elizabeth Moore, Head of the Art & Archaeology Department at the School of Oriental and African Studies, University of London · JPL radar scientist Dr. Anthony Freeman NASA Television is available through GE-2, transponder 9C at 85 degrees West longitude, vertical polarization, with a frequency of 3880 Mhz, and audio at 6.8 Mhz. Journalists may ask questions in the briefing remotely at participating NASA field centers. -end-
