Il lato destro della presunta piramide lo vedo, e ci sta tutto.
Ma non capisco il lato sinistro da dove salta fuori?
Parti da un presupposto sbagliato perchè non devi considerare le due immagini (quella discussa e quella precedente) aspettandoti una perfetta sovrapposizione dei lati della "piramide", perchè tra le due foto c'è una differenza di tremenda sovra-esposizione a causa della luce solare.
Il frame 20680 e anche quelli precedenti (gli ultimi 4-5) sono da considerare immagini "vuote", essendo gli scatti finali di quello che era il rollo n. 135 (magazine 135) montato sul Lunar Roving Vehicle (LRV).
I frame 20679 e 20680 rappresentano gli ultimi scatti del rollo 135 (caricato per l'EVA n. 2) prima di essere "sostituito" dal rollo n. "x" (come ad esempio il rollo 136, caricato per l'EVA n. 1).
Dal frame 20679 leggiamo infatti che l'immagine è sovraesposta:
http://www.lpi.usra.edu/resources/apoll ... -135-20679Quello che a noi interessa sapere è stabilire, senza alcuna approssimazione, quale inquadratura veniva prodotta poco prima e poco dopo l'immagine in oggetto. Dalla sequenza finale del rollo 135 abbiamo appreso che l'inquadratura puntava in basso, sulla struttura dell'LRV, sui sedili e sul suolo (o piano del veicolo) (
seats and floor).
Sono scatti finali fatti senza alcun senso, per volontà di chi voleva iniziare una nuova EVA con un rollo fresco. Lo possiamo constatare da questa trascrizione:

[Before taking Magazine 135/G off his camera, Jack advances the film and gets four frames, AS17-135- 20676, to 20679, showing the LRV seats and floor.]
[Schmitt - "During the pre-mission training, we spent a lot of time outside and pressurized, training for the EVAs down at the Cape in a simulated traverse area.]
[Training photo S72-48892 (scan by Ed Hengeveld) shows Jack and Gene on the 1-g trainer in the midst of the EVA training area at the Cape, complete with basalt boulders.]
[Schmitt - "You couldn't work ten hours like we did on the Moon, but we would work for like four hours. And we wore ourselves out before somebody had the bright idea - and I hope it was me, but I don't remember - of hooking the liquid-cooled garment up to some ice water. I'm surprised we didn't kill somebody from heat stroke. It was just too much. We shouldn't have been doing it. We didn't have any significant cooling for a long time - just an inadequate liquid-air cooling system in the lightweight PLSSs - and, then, during training for some mission, probably 15, we decided to have somebody walk behind the pressurized astronaut with a backpack full of ice water, and a hose going into the suit attached to the liquid cooled garment. And, of course, that made all the difference in the world. I think that was my suggestion, but I can't be sure; so much of that stuff happened synergistically. But I was worried and I know I made a big point to a lot of people for a long time that you were going to hurt somebody, that they were just getting too hot, including me.]
[Jack relates a variant of this story in his EVA-1 commentary at 118:39:52. The first half of this EVA-2 review was actually done some months before the EVA-1 review.]
[Cernan - "I don't think we had the ice-water cooling for the Apollo 14 EVA training; for me, that showed up on Apollo 17. Although Apollo 14 was a January launch and ours was a December launch, we trained all year long. It got hot down there at the Cape, and you worked hard. I never felt we were going to kill anybody; but the ice water did help. It made a big difference. It allowed you to work more efficiently and kept you from getting as hot and tired and irritable, and you got more out of training than you would have otherwise.]
