Seen here is the large Aitken crater on the farside of the Moon, hosting a complex array of terrain features. Aitken crater stretches 135 kilometers across and is 6 kilometers deep. Like the previously covered Aristarchus, it has an arc-shaped (near) central mountain. The other prominent feature of Aitken is

Here's a long-running wrinkled ridge on the Moon called Dorsum Zirkel, in the vast lava plains of Mare Imbrium. The Moon has many wrinkled features (Dorsa) across its surface. Wrinkles are tectonic features formed by compressive stresses on the lunar surface. The dark regions of the Moon — the

Seen here is a geological "fault" on the Moon, called Rupes Recta, as seen from orbit by NASA's Apollo 16. A fault like this is called a scarp when it separates two relatively level areas. Scarps are formed when two volumes of rock are displaced from
