The jumbled floor of Necho

The chaotic floor of Necho crater attests to a dynamic environment immediately after the impact event. LROC Narrow Angle Camera (NAC) observation M115502787RE, LRO orbit 2155, December 15, 2009; alt. 59.85 km, resolution = 0.96, field of view width = 960 meters [NASA/GSFC/Arizona State University].

Wide Angle Camera monochrome full image of the 30 km far side crater Necho, 490 km northeast of Tsiolkovskiy (5°N, 123.1°E); arrow indicates approximate location of NAC detail above.

Curious as to what's in the shadows? A more drastic stretch of the image can help.

A look into the shadows - close-up of the same NAC scene above, but "harshly stretched" to highlight shadowed terrain where boulders litter a dark slope in shadow, salvaging light scattered by the surrounding crater interior [NASA/GSFC/Arizona State University].

Stepping back to view the full width of the NAC frame, shows the interior of Necho exhibits a rich geologically-complex morphology, debris and melt deposits with substantial ponding. (NAC M115502787RE; field of view width = 2.4 km) [NASA/GSFC/Arizona State University].
