Martian rock hints at ancient dense atmosphere
Billions of years ago, Mars was warmer and wetter than today, perhaps because volcanoes belched enough carbon dioxide to create a blanketing atmosphere. But scientists have not been able to find many of the carbon-rich minerals they would have expected on the Martian surface had that been the case.
Curiosity rover finds large carbon deposits on Mars
NASA's Curiosity rover landed on Mars on Aug. 5, 2012, and has travelled more than 34 kilometres on the Martian surface. The discovery of carbonate suggests that the atmosphere contained enough carbon dioxide to support liquid water existing on the planet's surface. As the atmosphere thinned, the carbon dioxide transformed into rock form.
