60,000 feet above Earth, NASA is hunting for the minerals that power phones, EVs and clean energy
Unlocking the Secrets of the American West: NASA's High-Flying Hunt for Critical Minerals
The High-Tech Sensor: AVIRIS-5
In the vast expanse of the American West, a high-flying aircraft is on a mission to uncover the secrets of the desert landscape. NASA's ER-2 aircraft, equipped with the state-of-the-art AVIRIS-5 sensor, is scouring the terrain for critical minerals that power our modern world. The sensor, developed by NASA's Jet Propulsion Laboratory (JPL), is one of the newest tools in a joint research project between NASA and the U.S. Geological Survey (USGS) called GEMx.
The GEMx Project: A Joint Effort to Uncover Critical Minerals
The GEMx project is an ongoing research initiative that aims to search for surface traces of critical minerals in the American West. These minerals, including aluminum, lithium, zinc, graphite, tungsten, and titanium, are central to manufacturing consumer electronics, military technology, and clean energy solutions. The project's focus on the desert landscape is due to the unique properties of the terrain, which allows for more accurate mineral spectroscopy.
The Science Behind AVIRIS-5
AVIRIS-5 is an airborne visible/infrared imaging spectrometer that uses advanced technology to detect the reflected light from minerals. By analyzing the spectral fingerprints of these minerals, the sensor can identify their presence and composition. The sensor's ability to detect these unique chemical structures is made possible by its advanced optics and sophisticated algorithms.
The Importance of Critical Minerals
Critical minerals are essential components in various industries, including electronics, energy, and defense. The USGS defines these minerals as those that have significant consequences for the economic or national security of the U.S. The importance of these minerals cannot be overstated, as they are used in the manufacturing supply chains for crucial technologies such as semiconductors, solar electricity systems, and electric vehicle batteries.
The White House's Executive Order: Boosting Domestic Production
In March 2025, the White House issued an Executive Order to boost the production of critical minerals in the U.S. The order stated that American national and economic security are now acutely threatened by our reliance on hostile foreign powers' mineral production. This move highlights the importance of domestic production and the need for reliable sources of critical minerals.
Beyond Mineral Detection: The Breadth of AVIRIS-5's Applications
While AVIRIS-5 is currently being used to hunt for critical minerals, its technology has far-reaching applications beyond mineral detection. According to Dana Chadwick, a JPL Earth system scientist, the sensor can be used for various purposes, including land management, snowpack water resources, and wildfire risk assessment. The breadth of different questions that can be taken on with this technology is truly exciting.
The Future of AVIRIS-5: En Route to Europa
One of the most exciting applications of AVIRIS-5's technology is its use on the Europa Clipper mission, which is set to launch in the near future. The mission will search for the chemical ingredients needed to support life on Europa, an ocean moon of Jupiter. This mission highlights the potential of AVIRIS-5's technology to explore the vast expanse of our solar system and uncover the secrets of the universe.
Conclusion
The AVIRIS-5 sensor is a cutting-edge technology that is revolutionizing the way we search for critical minerals in the American West. Its advanced optics and sophisticated algorithms make it an invaluable tool in the GEMx project's mission to uncover the secrets of the desert landscape. As we continue to rely on these minerals for our modern world, the importance of domestic production and reliable sources cannot be overstated. The future of AVIRIS-5 is bright, and its applications will continue to expand beyond mineral detection, shaping the course of scientific research and exploration for years to come.
