From The Earth To The Moon And On To Mars Esa And Nasa Take Decisions And Program For The Future
Along the way it has snapped thousands of photos, analyzed the chemistry of rocks, and tested new technologies such as a machine that splits up carbon dioxide to form breathable oxygen. NASA’s Perseverance rover made this selfie close to a rock nicknamed Rochette on September ten, 2021, after drilling two chalk-size rock cores—the initially productive samples the rover collected. The mineralogical characteristics caused by serpentinization and carbonation are rare in Martian meteorites. Orbital surveys of Mars discovered evidence of both processes on the planet’s surface, and scientists have identified carbonation in other Martian meteorites, all younger than ALH84001. But the...
