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

Mars had lakes & streams long after early wet era

Lakes and snowmelt-fed streams on Mars formed much later than previously thought possible, according to new findings using data primarily from NASA’s Mars Reconnaissance Orbiter. The recently discovered lakes and streams appeared roughly a billion years after a well-documented, earlier … Continue reading

Did lake-effect storms make Martian snowbelts?

Numerous places on Mars show erosion by precipitation, whether as rainfall or runoff from melting snow. The precipitation could have come from a thicker atmosphere or a temporary boost in atmospheric temperature and density following a large impact. Both scenarios … Continue reading
