NASA's AVIRIS-5: Unlocking the Secrets of Earth's Surface from 60,000 Feet
A cutting-edge NASA sensor, AVIRIS-5, has taken to the skies to aid geoscientists in mapping rocks hosting critical minerals like lithium on Earth's surface. Cradled in a high-altitude research airplane, the sensor, short for Airborne Visible/Infrared Imaging Spectrometer-5, is part of the largest airborne campaign of its kind in US history, collaborating with the US Geological Survey (USGS).
The mission, dubbed GEMx (Geological Earth Mapping Experiment), aims to modernize mapping of the nation's surface and subsurface. Over 200 hours of high-altitude flights have been logged over Nevada, California, and other Western states since this year began. This endeavor is part of a larger USGS initiative called Earth Mapping Resources Initiative (Earth MRI).
AVIRIS-5 uses advanced imaging spectrometry to detect the spectral "fingerprints" of minerals and compounds in reflected sunlight. By analyzing these unique chemical structures, the sensor can identify valuable resources like lithium-bearing clays. The device is equipped with black silicon, one of the darkest materials ever manufactured, which traps stray light, enhancing its performance.
This technology has been pioneered at NASA's Jet Propulsion Laboratory (JPL) since the late 1970s and has been successfully deployed in various missions across the solar system. The latest model boasts a spatial resolution twice as fine as its predecessor, allowing it to resolve areas ranging from less than a foot to about 30 feet.
So far, AVIRIS-5 has made an exciting early finding β a lithium-bearing clay called hectorite β identified in abandoned mines in California. This discovery highlights the potential for this technology to aid communities in capturing new value from old and abandoned prospects, as well as identifying sources of acid mine drainage.
The GEMx research project is expected to last four years, with funding from the USGS Earth MRI initiative through investments from the Bipartisan Infrastructure Law. The mission will capitalize on both NASA-developed spectroscopic imaging technology and expertise in analyzing datasets to extract critical mineral information.
As part of this endeavor, AVIRIS-5 will aid researchers in exploring issues like land management, snowpack water resources, and wildfire risk, with a focus on identifying sources of critical minerals at risk of supply chain disruption. The sensor's advanced capabilities are set to unlock the secrets of Earth's surface from 60,000 feet, providing valuable insights for geoscientists and policymakers alike.
