Story summary

NASA's Perseverance rover found that Jezero Crater experienced multiple distinct phases of water activity on Mars.
Researchers used the Mineral Identification by Stoichiometry (MIST) algorithm to identify 24 mineral types.
This sequence marks a shift from harsh, acidic waters to neutral and alkaline conditions over time.
The study was published in the Journal of Geophysical Research: Planets and shows early acidity hindered life while later phases increased habitability.
