A team of NASA scientists is using a high-altitude aircraft and a sophisticated imaging spectrometer built by NASA’s Jet Propulsion Laboratory in Pasadena, California, to study environmental impacts caused by the devastating Southern California wildfires. NASA’s ER-2, based at Armstrong Flight Research Center in Palmdale, California, flies as high as 70,000 feet (21,300 meters), almost twice as high as a commercial airliner.
