SOU-SOL006-backshell-03-PIA00790_modest.jpgThe "Backshell" - Sol 6324 visiteCaption NASA:"During the Entry, Descent and Landing phase of the mission, the final step is the separation of the Lander and it's surrounding Airbags from the Backshell. The conical Backshell above the Lander contains 3 solid rocketmotors each providing about a ton of force for over 2". They are activated by the computer in the Lander. Electrical wires that run up the bridle close relays in the Backshell which ignite the 3 rockets at the same instant. The brief firing of the solid rocketmotors at an altitude of 80-100 meters is intended to essentially bring the downward movement of the Lander to a halt some 12 meters above the Surface. The bridle separating the Lander and Heat-Shield is then cut in the Lander, resulting in the Backshell driving up and into the Parachute under the residual impulse of the rockets, while the Lander, encased in airbags, falls to the Surface. The Backshell is to the S/E of the Lander, and in front and to the left of "Big Crater".

SOU-SOL039-1~0.jpgPre-dawn clouds (1) - Sol 39119 visiteCaption NASA originale:"These are more wispy blue clouds from Sol 39 as seen by the Imager for Mars Pathfinder. The bright clouds near the bottom are about 10 above the horizon. The clouds are believed to be at an altitude of 10 to 15 Km and are thought to be made of small water ice particles. The picture was taken about 40 minutes before Sunrise".

ATTENZIONE: nel prossimo frame, una (modesta, ma significativa, almeno a nostro parere)"rivelazione"...

SOU-SOL036-1.jpgMartian Skies, according to NASA... - Sol 3671 visiteCaption originale di Don Davis:"Only one instance of color adjusting of images has aroused any concern to me regarding integrity of presentation. This Pathfinder Martian Sunrise photo was first released with a pink cloudy sky; a later version of the same picture, on the right, balanced with more care towards presenting what the cameras saw, revealed a much more subdued scene. Clearly the conclusions on cloud lighting and atmospheric conditions will be affected by such colors".
Nota: Don Davis molto attento e "comprensivo" verso la NASA e noi possiamo anche capirlo.
Tuttavia, a nostro modo di vedere, quando l'Ente Spaziale pi moderno, famoso ed accreditato al Mondo rilascia al Pubblico, in tempi diversi (e senza precisare alcunch), due (o pi) immagini identiche le quali, per, sono state sottoposte ad una tale ri-elaborazione da apparire, alla fine, come totalmente diverse, esso fa solamente - scusateci - "casino".
In questo modo, come dimostrato nell'articolo del Dr Fienga pubblicato sul Nexus Magazine ("Gioco di Specchi"), non si rende un buon servizio n alla Scienza, n alla Divulgazione.
In questo modo, insomma, si fa solo confusione (per non dire che, alla fine, ci rimane pure il sospetto che il caos sia stato voluto...).
