The Near Side Megabasin

Chapter 1 presented the history of the discovery of major differences between the near side and the far side of the Moon, based on images returned from spacecraft. In this chapter, additional evidence of difference is provided and a new view of the cause of the difference is discussed. There is good evidence that very early in the history of the Moon, a giant impact created the Near Side Megabasin. The near side is nearly all within the depression of this giant basin, and its rim and ejecta cover the far side.
