DARPA is Using Earth’s Atmosphere as a Sensor to Detect Secret Explosions and Spacecraft Reentries

The Defense Advanced Research Projects Agency (DARPA) has revealed Earth’s atmosphere can serve as a powerful sensor, allowing the detection and modeling of events on the ground and in space with incredible precision. Once thought impossible, the new sensor capabilities unveil the ability to follow energy from their beginnings as small-scale, meters-wide disturbances as they propagate over much greater distances “and potentially around the world…
