NASA has a new high-tech sensor to help the search for critical minerals in the American West.
The sensor is called AVIRIS-5 (Airborne Visible/Infrared Imaging Spectrometer-5), and it comes from technology developed by NASA's Jet Propulsion Laboratory (JPL) back in the 1970s. About the size of a microwave, AVIRIS-5 fits inside the nose of one of NASA's ER-2 high-altitude research aircraft. The sensor's first iteration was employed in 1986, and JPL has worked to improve it ever since.
