QA-VikingLS-4.jpgViking One: the Landing Site - First Color Picture (Don Davis' interpretation)113 visiteCaption originale:"My current thinking of how the first color picture should look, adjusted as it would appear 'on site'. If anything the soil is a bit too light, but the limitations of any pictorial medium compared to reality must be taken into account. I think we will be surprised by the electronic images captured by as yet undesigned hand held cameras. Such a picture taken at the Viking One Site, assuming it is the same as we last saw it by then, may look something like this".
Nota: alla NASA devono aver apprezzato molto il Lavoro di Don Davis. Perchè? Perchè, in svariati frames a colori-approssimativamente-veri dei MER Spirit ed Opportunity (soprattutto Opportunity), Marte ed il suo Cielo appaiono proprio così: verdognoli! In molti frames Spirit, invece (e su tutti ci mettiamo il "Santa Anita Panorama" - Sez. "Mars in Colors") il trionfo è quello dei colori di cui alla versione n. 3.

ZD-E-Viking1-p4041b.jpgThe South-western horizon of Viking 1 (2)107 visiteCaption NASA originale:"Almost certainly this is the upraised rim of an impact crater, about 500 mt in diameter and 2,5 Km distant. Part of the far side of the central cavity can be discerned toward the left, particularly in picture n. (3)".

ZD-E-Viking1-p4041a.jpgThe South-western horizon of Viking 1 (1)103 visiteCaption NASA originale:"These are three views looking toward the South-West horizon at different times of day: early morning (1), early afternoon (2) and late afternoon (3). Different lighting accentuates different detail in both nearfield and farfield. Of special significance is the symmetrical skyline ridge revealed in all 3 pictures".

QC-VikingOne-The_B-Rock-PIA00386-EB01.jpgThe "B-Rock" (RAW Original Frame + EDM; credits: Elisabetta Bonora)103 visiteEd ecco quindi, una volta che si è passati dall'inset del Corsera all'osservazione del RAW-Frame Viking One Originale, che la nostra "lettera B" (con il "2" e la "C" che svaniscono nel nulla...) si risolve piuttosto chiaramente in un effetto di pareidolìa il quale venne creato, artifici e raggiri a parte, dalla presenza, sulla roccia misteriosa, di una serie di scanalature curvilinee (peraltro comuni su innumerevoli rocce presenti nell'area di Landing della Sonda).
Scanalature, tra l'altro, profonde (probabilmente) almeno un paio di centimetri e quindi capaci di generare delle ombre che, di fatto evidenziando i margini dei piccoli solchi in questione, furono causa di ulteriori ed estremamente ingannevoli effetti visivi (e comunque, volendo fare i "Pignoli", diciamo che al di sopra della lettera "B" - e tralasciando l'inesistente "2" e la "C", si può ben distinguere una sorta di "8"...).
Che altro aggiungere? Complimenti e congratulazioni ad Elisabetta e "Mistero" risolto!MareKromium

QB-VikingOne-PIA08616-00.jpgViking One: the Landing Site, 30 years after the landing... (1)100 visiteCaption NASA originale:"Viking 1 landed 30 years ago, on July 20, 1976. It was the first U.S. landing on Mars and a very exciting time for Mars Exploration. Since that time, 4 additional Spacecrafts have successfully landed on Mars and conducted their science investigations. Today, new missions to the Martian Surface are in the works, with landings expected in 2008 (Phoenix) and 2010 (Mars Science Laboratory).
The Viking 1 Lander is difficult to see in MGS-MOC images. The Western Chryse Planitia Landing Site is often obscured by dust hazes and occasional storms, especially during Northern Winter, which would otherwise be the best time to look for the Lander from orbit because the Sun casts longer shadows in Winter.
When the atmosphere is clearest, in portions of the Spring and Summer, the Sun is higher in the sky as seen from MGS's orbit. The spacecraft always passes over the Landing Site Region around 2 p.m. in the afternoon".

ZE-I-Viking1-p139.jpgColor snap-shots from Viking 1 (10)96 visite"...Figure (10) can best be assigned to the "Special Effects" Category. It illustrates one of the many ways in which black and white images can be combined and printed in color to yield unusual patterns. In this instance an early morning image is assigned the color yellow and a picture taken in the afternoon is assigned the color blue. Although colors produced in this way are completely false, important details in the scene are sometimes favorably accentuated..."

ZD-E-Viking1-p7273b~0.jpgThe South-western horizon of Viking 1 (3)95 visiteCaption NASA originale:"This same crater has also been identified in Orbiter photographs and then used to locate the Lander position. Also visible beyond the crater rim is a ridge 8 to 10 Km distant".
