Craft reveals Martian site of ancient water
The distribution of materials in this composite image of the Nili Fossae region of Mars tells scientists that water resided there no more recently than nearly 4 billion years ago. Green indicates clay minerals that formed in a wet environment. Red depicts the mineral olivine, which formed about 3.8 billion years ago, according to the […]
