ALT In this view of the Moon, the near side (the hemisphere we see from Earth), is visible at the top half of the Moon disk. It is identifiable by the dark splotches. These are ancient lava flows from a time early in the Moon\u2019s history when it was volcanically active. The large crater that appears below the lava flows, dark in the center, is Orientale basin, a nearly 600-mile-wide crater that straddles the Moon\u2019s near and far sides as is partly visible from Earth on the edge of the Moon. In this image, we have a full view of the crater. Everything below the crater is the far side, the hemisphere we don\u2019t get to see from Earth because the Moon rotates on its axis at the same rate that it orbits round us. Credit: NASA
