Curiosity findings from Yellowknife Bay sharpen CO2 paradox of ancient Mars climate

Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet’s surface. Yet, the ancient sun was about one-third less warm and climate modelers struggle to produce scenarios … Continue reading
