NASA's EMIT instrument is being used to analyze mine waste from space, identifying abandoned mines in the American West that require urgent cleanup to protect waterways from pollution. This technology helps prioritize remediation efforts, focusing on areas where water quality is most at risk. Abandoned mines pose a significant threat to the region's water quality, but satellite technology is aiding in efficiently and effectively addressing this environmental challenge.
