- With more than 700 marsquakes detected so far, scientists have a clearer picture of the interior structure of Mars than ever before. That picture shows Mars has a liquid metal core, a thick mantle with a rocky layer above a more fluid layer, and a crust that is proportionally thicker than Earth’s. https://eos.org/articles/mars-from-the-insight-out 617 comments space
