An astronaut's view looking south-eastwards across the Mare Imbrium region of the Moon. The prominent crater towards the upper left is Aristarchus, which is thought to be one of the youngest on the Moon (c. 400 million years old). Closer than Aristarchus are the traces of a much older crater, Prinz, that was flooded by the lavas that spread to form the Mare basins 3500 million years ago. The sinuous features are lunar rilles. These are thought to be channels or collapsed lava tubes produced by flowing lava toward the end of the Mare-forming events.
