What does the moons backside look like when the side facing the earth is fully illuminated by the sun?

When the side of the Moon facing Earth is fully illuminated by the Sun, the far side, often referred to as the "dark side," is in complete darkness. This side features a rugged terrain with numerous impact craters, large lunar highlands, and fewer maria (the dark basaltic plains) compared to the near side. The far side's landscape is more heavily cratered and lacks the large, smooth plains that characterize the side visible from Earth. As a result, it appears more ancient and less geologically active.
