Curiosity Finds First In Situ Evidence of Carbon Cycle on Ancient Mars
A surprise discovery in Gale Crater is the component that was missing in the puzzle of Mars 's climate history. There, embedded in the bedrock, the Curiosity rover has identified a mineral called siderite that can only have formed from the precipitation of carbon from the Martian atmosphere.
