Summary
A newly discovered 1.27-billion-year-old Mars meteorite, Northwest Africa (NWA) 13441, found in Algeria, is providing new insights into a previously unknown period of Martian geological history. This meteorite, a shergottite with chondrite-like neodymium isotopes, helps fill a significant gap in the Red Planet's geologic record and suggests deeper parts of Mars have remained largely untouched since its formation.
