Outside the window, the aircraft is being readied for a high-altitude mission supporting the Geological Earth Mapping Experiment (GEMx)<\/a>, a multi-year NASA\u2013U.S. Geological Survey campaign to map critical mineral resources across the Western United States. The GEMx team believes that undiscovered deposits of at least some of the 50 mineral commodities deemed essential to U.S. national security, to the tech industry, and to clean energy exist domestically, and modern mineral maps will support exploration by the private sector.<\/p>\n In 2025 alone, the ER-2 flew 36 science missions, collecting more than seven billion measurements over 200 flight hours, contributing to the largest airborne surface mineralogy dataset ever gathered in a single NASA campaign. For this mission, pilots flew at approximately 65,000 feet altitude, requiring them to wear specially designed pressure suits to safely operate in the thin atmosphere.<\/p>\n Image credit: NASA\/Christopher LC Clark<\/em><\/p>\n Text credit: Darin L.
