Referred to as the \u201cBroom Point member\u201d by the rover\u2019s science team, this sequence of layered bedrock is likely more than 3.9 billion years old, making it among the oldest terrain ever examined by a Mars rover.<\/p>\n<p data-block-key=\"aaub1\">Released Wednesday in the <a href=\"https:\/\/agupubs.onlinelibrary.wiley.com\/doi\/10.1029\/2026JE009779\" rel=\"nofollow noopener\" target=\"_blank\">Journal of Geophysical Research: Planets<\/a>, the findings offer a window into one of the most tumultuous chapters in the history of the solar system.<\/p>\n<p data-block-key=\"5vspk\">\u201cSince leaving Jezero, Perseverance has been exploring a brand-new frontier, both geographically and geologically \u2014 a chapter of Martian time that predates the crater itself,\u201d said Ken Farley, Perseverance deputy project scientist at Caltech in Pasadena, California. \u201cOn Earth, our earliest geologic history has been fundamentally broken up, deformed, and erased by plate tectonics.
