Martian Meteorite Discovery Fills Geological History Gap

A newly discovered Martian meteorite has been dated to approximately 1.273 billion years old, originating from a previously unsampled, pristine source on Mars. This finding, published in Geochimica et Cosmochimica Acta by a USRA team, helps bridge a significant 1.8-billion-year gap in understanding Mars' geological history. It provides crucial insights into a period for which no shergottite samples previously existed.
