Lightning Detector

The antenna pictured below is part of a NASA-developed system for pinpointing the location and altitude of lightning activity in the atmosphere. Developed by Kennedy Space Center, it is called the Lightning Detection and Ranging (LDAR) system. Its original purpose was to give space launch controllers additional information on which to base launch or no launch decisions. It may also have utility in civil aviation. Last summer, NASA and the Federal Aviation Administration jointly conducted at Patrick Air Force Base, Florida-tests of LDAR's potential as an aid to air traffic control. The results are being evaluated.
