      >”This yields a final estimated duration of 0.8–1.5 **million** years for the presence of stable aqueous conditions in Utopia Planitia. … suggesting that Utopia Planitia hosted a long-lived and evolving aquatic system during the Hesperian epoch, rather than a short-lived or rapidly evaporating water body,”

      Is this a typo? 1.5 million years is not what I’d consider a long lived body of water on a planetary timescale.
