美国宇航局的好奇号探测器在盖尔陨石坑湖床岩石中发现了高于正常的锰含量，这表明古代火星曾有过类似地球的条件。 NASA's Curiosity rover found higher-than-usual manganese in Gale Crater lakebed rocks, suggesting ancient Mars had Earth-like conditions.

美国宇航局的一个研究小组利用好奇号火星车上的 ChemCam 仪器，发现火星盖尔陨坑的湖床岩石中锰的含量高于正常水平，这表明这些沉积物是在河流、三角洲或古老湖泊的岸边形成的。 A NASA research team using the ChemCam instrument onboard the Curiosity rover discovered higher-than-usual amounts of manganese in lakebed rocks within Gale Crater on Mars, suggesting these sediments were formed in a river, delta, or near the shoreline of an ancient lake. 该研究结果发表在《地球物理研究杂志：行星》上，表明古代火星可能曾拥有类似地球的条件。 The findings, published in the Journal of Geophysical Research: Planets, indicate that ancient Mars may have had Earth-like conditions.
