NASA Prepares 2025 Carruthers Mission to Explore Earth’s Hidden Hydrogen Halo

NASA’s Carruthers Geocorona Observatory, launching in 2025, will capture ultraviolet light from hydrogen atoms to map Earth’s faint geocorona. Operating a million miles sunward, it will study how solar activity drives atmospheric loss, improves satellite protection, and reveals clues to planetary habitability, providing critical insight for future crewed and robot…
