Ancient Martian Meteorite Unlocks Secrets of a 'Lost Age' in Red Planet History
A newly discovered Mars meteorite, NWA 13441, found in Algeria and dated at 1.27 billion years old, is providing unprecedented insights into a vast, previously unknown period of Martian geological history. Its unique composition, blending common shergottite features with rare-Earth neodymium isotopes typically found in primordial chondrites, challenges existing theories about Mars's internal structure and formation. This space rock fills a critical 600-million-to-2.4-billion-year gap in the Red Planet's geological record, suggesting deeper, undisturbed reservoirs and offering new clues about the early solar system and Mars's magmatic past. Scientists anticipate further analysis will illuminate the planet's ancient volcanic activity and its connection to other early Martian meteorites.
