- Mars may have carried liquid water more recently than previously thought, according to converging analyses of rover data.
- China's Zhurong rover identified the first primary evaporites on Mars, with crystals potentially preserving 757-million-year-old brine.
Why it matters: The Zhurong rover's 757-million-year-old brine evidence, combined with reanalysis of Spirit's old data, points to liquid water on Mars far more recently than previously assumed, expanding the window for potentially habitable surface conditions.
