There , sunlight is blocked by the 300 - meter tall crater wall from vaporizing the water - ice on the crater floor into the thin martian atmosphere 在那里，阳光被300公尺高的陨坑边墙所挡住，以免阳光使这块在陨石坑底的水冰蒸发到火星稀薄的大气之中。
Knowledge of the impact location allowed us to reconstruct the trajectories and distribution of material ejected from the crater and evaluate the extent of the fires 对撞击地点的了解，让我们重建物体从陨石坑喷出的轨迹与分布，并评估燃烧的程度。
Images taken of the same areas over time showed investigators that liquid water likely flowed through gullies in martian craters during the past seven years 从同一地点数次拍摄的照片向调查员显示出在过去的7年中似乎有液态水流过火星陨石坑的山谷。
