APOLLO 15 AS 15 84-11242 HR-1.jpgAS 15-84-11242 - Pluton and Eaglecrest Crater (HR)168 visiteOriginal caption:"106:56:54 MT. This first frame in Dave's 500-mm SEVA coverage of the North Complex shows Pluton Crater and, above it, Eaglecrest Crater. This is one of the few 500-mm images that Dave took without the camera being perfectly steady. By using "FocusMagic" to deblur the image it seems that a 4-pixel deblurring (next frame) along a line 50° counterclockwise from vertical worked best.

APOLLO 15 AS 15 84-11243 HR-1.jpgAS 15-84-11243 - Pluton Crater (HR)174 visiteOriginal caption:"106:56:54 MT. Rightward of AS 84-11242, showing more of Pluton Crater.

Nota: una curiosità. Questo cratere che abbiamo visto - discretamente - negli ultimi 3 frames è stato chiamato "Plutone" poichè esso, a differenza della grande maggioranza dei crateri lunari esplorati (per così dire "da vicino") dagli Astronauti, pare che fosse profondissimo.
Talmente profondo, che non si riuscì - forse anche a causa della sua conformazione e configurazione interna - a vederne il fondo.
Ed a proposito dell'interno dei crateri: avete notato che sono piuttosto rare (eufemismo!) le fotografie Apollo che mostrano l'interno dei crateri di media dimensione investigati dagli Astronauti? Forse, l'idea di sporgersi verso l'interno di uno di quei "buchi" faceva un pò paura. O forse quello che c'è dentro ai crateri di media dimensione investigati dagli Astronauti è ancora Top-Secret (Cone Crater docet).
Chissà...

APOLLO 15 AS 15 84-11247.jpgAS 15-84-11247 - The western base of Mt Hadley353 visiteSpettacolare frame che riprende le pendici del versante occidentale del Monte Hadley: una "piccola montagna" (piallata, come la quasi totalità delle colline e dei monti della Luna) che ha comuque riservato - ci pare - agli Astronauti ed a noi un grande quantitativo di sorprese (oltre che una serie di scorci davvero splendidi).

APOLLO 15 AS 15 84-11250 HR.jpgAS 15-84-11250 - Silver Spur (HR)205 visiteOriginal caption:"Dave Scott took this 500-mm picture of Silver Spur during the SEVA at about 106:58:07 MT. Silver Spur is named for Caltech geologist Lee Silver, who showed Scott and Irwin that field geology could be exciting (see Don Wilhelm's excellent book "To a Rocky Moon").
Note that there appear to be 2 systems of lineations in Silver Spur. One set consists of what appear to be about ten thick beds which appear to dip down from right to left as seen from the LM. As discussed in the Apollo 15 Preliminary Science Report, this set of lineations may well represent real structure in the mountain.
The second set of lineations consists of closely-spaced, nearly horizontal lines and these lines may be lighting artifacts".

APOLLO 15 AS 15 84-11257 G-1.jpgAS 15-84-11257 - Layering?146 visiteOriginal caption:"123:19:35 MT. Rightward from AS 84-11256 with good overlap. Note the apparent layering in the formation just below center on the right. The mare surface is believed to have been built up in a series of relatively thin lava flows with some impact 'weathering' of each fresh surface before the next flow. A cross-section would show a series of thin, horizontal layers".

APOLLO 15 AS 15 84-11309.jpgAS 15-84-11309 - Up to the top of Mt Hadley355 visiteCaption NASA originale:"This is the first in a vertical strip of 500mm images of Mt. Hadley taken by Dave Scott from Station 6.
Two sets of linear features can be seen on the mountain: a set running diagonally down from the upper right to the lower left and a nearly horizontal set dipping down slightly to the left. The diagonal set is the more prominent when the mountain is viewed as a whole and these are believed to be due to lighting effects. The features in the horizontal set, when viewed from lunar orbit, appear to be benches that may have resulted from slumping on the steep mountain face".
