On Wednesday, NASA and the Department of Homeland Security (DHS) will demonstrate a new radar device capable of detecting human heartbeats trapped behind as much as 20 feet of solid concrete rubble. The device, called Finding Individuals for Disaster and Emergency Response (Finder), will be shown at the Virginia Task Force 1 Training Facility at 9850 Furnace Road (use 9900 for GPS) in Lorton, Va. beginning at 10:30 a.m. on September 25. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., developed Finder in collaboration with the DHS’s Science and Technology Directorate.
