摘要

描述
English: Necho, on the far side of the moon.
A version of this photo was used in Figure 18-7 of the Apollo 14 Preliminary Science Report (SP-272), which has the following caption:
View of the bright-haloed crater ("the bright one") shown in figure 18-6 (80-mm lens was used). The low-Sun angle (approximately 17°) is favorable for studying the details of the crater wall and floor and the fine textures on the ejecta blanket.

The text of the Report (chapter 18, Orbital-Science Photography) states the following based on this photograph:

The crater has a rim-crest diameter of approximately 35 km, but the general outline is partly distorted by incipient major wall failure and slumping. Looped secondary crater chains, a braided radial facies, finely terraced walls, and major fracture patterns are clearly seen. The interior terraces within this crater generally trend to the northwest, as opposed to the usual concentric terraces seen in craters of similar age in this size range. In this case, it is evident that most of the postcrater gravitational filling occurred by the collapse of the partly shadowed wall.
