Across billions of years and millions of miles, a small rover drilling centimetres into Martian rock has returned evidence that the Red Planet once held the atmospheric conditions necessary for liquid water — and perhaps for life. Siderite, an iron carbonate mineral found at three separate sites within Gale Crater, tells a story of a thicker, warmer ancient Mars before solar winds slowly stripped its sky away. University of Calgary geochemist Ben Tutolo and his colleagues have published these findings in Science, not as proof that Mars was inhabited, but as confirmation that it could have been
