Across the rust-colored floor of Gale Crater, a NASA rover has read a message written in stone 3.7 billion years ago: Mars once held open lakes, their surfaces kissed by wind and air. Tiny wave ripples — no taller than a grain of rice — have overturned long-held assumptions that Martian water lay forever sealed beneath ice, revealing instead a world that was, for a meaningful stretch of deep time, genuinely hospitable. The discovery does not confirm that life arose on Mars, but it quietly extends the invitation it may once have received.
