美国航天局的Curiosity rover 发现了火星上碳循环的证据 表明地球可以支撑过去的生命 NASA's Curiosity rover has found evidence of a carbon cycle on Mars, suggesting the planet could have supported life in the past. 在Gale Crater发现的铁碳酸铁矿, 表明火星曾经拥有足以支撑液态水的 二氧化碳气候。 The discovery of siderite, an iron carbonate mineral, in Gale Crater indicates Mars once had a climate with enough carbon dioxide to support liquid water. 虽然火星大气层逐渐缩小, 这些发现帮助科学家了解 地球保护生命的潜力 及其气候史。 While Mars' atmosphere has thinned over time, these findings help scientists understand the planet's potential to harbor life and its climate history.
