On a rust-colored world billions of years in the making, a small human-built machine paused to photograph itself against a landscape older than Earth's continents. In March 2026, NASA's Perseverance rover reached the westernmost point of its journey at a region called Lac de Charmes, where it encountered rock formations that may predate the very crater it calls home. The minerals and structures it found there — volcanic intrusions, shattered megabreccias, ancient igneous stone from deep within Mars' crust — are not merely geological curiosities, but potential answers to the oldest question we
