SOU-SOL006-backshell-00.jpgThe "Silver-Sphere", near Pathfinder... - Sol 6202 visiteEd ecco un frame che abbiamo fatto davvero fatica a trovare, ma del quale conoscevamo l'esistenza: la Backshell della Sonda Pathfinder.
E' evidente che le fattezze di questo oggetto, tessitura superficiale e luminosit incluse, sono IDENTICHE a quelle dell'oggetto rinvenuto dal Rover Spirit a poca distanza dal Cratere Bonneville (leggete l'articolo pubblicato su TruePlanets per maggiori informazioni e dettagli).
Mistero risolto, dunque? La Silver Sphere di Spirit solo la sua Backshell? Apparentemente si, ma la NASA (si, proprio la NASA!) ad ESCLUDERE questa ipotesi, collocando la Backshell di Spirit (vedi la mappa allegata all'articolo summenzionato) in un punto completamente diverso rispetto al luogo in cui le immagini che abbiamo, invece, la collocherebbero (e cio a poche decine di metri dal rim di Bonneville Crater).
E allora? E allora, come si detto...Il Mistero si infittisce!
Caption NASA originale:"Super-Resolution image showing the Mars Pathfinder Backshell - This image was created from 25 nearly identical frames to give one HR view of the area looking towards Big Crater. The backshell is the bright white spot at middle-left. The 2,8 mt wide and 2,1 mt high Backshell, separated from the Lander a few seconds before landing, and appears to be about 1200 mt from the Lander, to the South-South-East".

SOU-SOL011-marspath_sunset4.jpgClouds in the Martian sunset (True Colors; credits: NASA/JPL)135 visiteUn bellissimo e "veritiero" (a quanto dicono alla NASA) tramonto Marziano a colori. Questa la caption originale all'immagine, ripresa dalla Sonda Pathfinder nel 1997: "You've had a hard day rolling past Martian rocks, so now just relax your APXS and enjoy the Martian Sunset. The above pictures taken by Mars Pathfinder highlight how clouds vary during the end of a Martian day. The Atmosphere on Mars is much thinner than on Earth and dominated by CO2 rather than Nitrogen. Clouds on Mars can be Water or Carbon Dioxide based, depending on conditions, whereas Earth's clouds are all water based. At night the temperature at Sagan Memorial Station will dip from about -15 degrees Celsius (+4 Fahrenheit) to -77 degrees Celsius (-107 Fahrenheit). Temperatures only this cold won't bother Sojourner".
Dati interessanti, senza dubbio. Voi che ne dite? I colori Vi sembrano veritieri?

SOU-SOL033-PIA01006.jpgThe "Meteorology Mast" - MET - Sol 33 (Enhanced Natural Colors; credits: NASA/JPL)103 visiteCaption NASA originale:"The Mars Pathfinder Meteorology Mast casts a shadow on the Lander Solar Array, as seen in this superpan mosaic. Looking to the South/East during the morning, the windsocks are slightly tilted, indicating the presence of a light wind from the South/West. The MET mast measured the temperature, pressure and wind speed at the Pathfinder Landing Site. During the mission, the instrument returned 8,5 million individual measurements from the Surface of Mars".

SOU-SOL016-PIA00784.jpgPre-Dawn Clouds on Mars - Sol 16 (True Colors; credits: NASA/JPL)188 visiteCaption NASA:"Pink Stratus Clouds are coming from the North/East at about 15 miles per hour (6,7 meters/second) at an approximate height of 10 miles (about 16 Km) above the Surface. The clouds consist of water ice condensed on reddish dust particles suspended in the Atmosphere. Clouds on Mars are sometimes localized and can sometimes cover entire Regions, but have not yet been observed to cover the entire Planet. The image was taken by the Imager for Mars Pathfinder (IMP) on Sol 16 about forty minutes before Sunrise showing areas of the Eastern Martian Local Horizon".

SOU-SOL013-Sunset-NASA.gifSunset over Ares Vallis - Sol 13 (GIF-Movie - False Colors; credits: NASA)88 visiteCaption NASA:"Animation of the Martian Sunset.
This movie is made from 9 images of the twilight following Sunset over Ares Vallis. The images are enhanced in order to show the very subtle features in the haze, which are probably caused by layers that are slightly dustier than the surrounding air. The color is not the true color of the sunset - that is shown in other images.
At the beginning, the Sun is on the horizon just to the right of the frame, and it sinks during the next hour. At the time of the last image the sky is only 1% as bright as at the beginning, but the IMP can easily adapt to the darkness and return these pictures. Because there is so much dust extending high into the Martian Sky, the Sky stays bright for more than an hour after sunset".MareKromium

SOU-SOL033-Landscape-PIA01120.jpgMartian Landscape - Sol 33 (Enhanced True Colors; credits: NASA/JPL)196 visiteCaption NASA:"The Sojourner Rover deploys the Proton X-Ray Spectrometer" onto the rock named "Moe" within the "Rock Garden" in this 75- image, color-enhanced mosaic taken by the imager on the Lander. Image of the Rover in the "Rock Garden" was taken on a different day than the terrain image. The view is to the South/West, with the Carl Sagan Memorial Station in the foreground and South Twin Peak on the horizon about 1 km from the Lander".

SOU-SOL024-Sunset-PIA00920_modest~0.jpgSunset on Mars - Sol 24 (True Colors; credits: NASA/JPL)241 visiteCaption NASA:"This is a close-up of the Sunset on Sol 24 as seen by the Imager for Mars Pathfinder. The red sky in the background and the blue around the Sun are approximately as they would appear to the human eye. The color of the Sun itself is not correct - the Sun was overexposed in each of the 3 color images that were used to make this picture. The true color of the Sun itself may be near white or slightly bluish".

SOU-SOL016-Clouds-PIA00785.jpg"Cloudy Sky" on Mars - Sol 16197 visiteCaption NASA:"This is the first image ever taken from the Surface of Mars of an overcast sky. Featured are stratus clouds coming from the North/East at about 15 miles per hour (6,7 meters/second) at an approximate height of 10 miles (about 16 Km) above the Surface. The "you are here" notation marks where Earth was situated in the sky at the time the image was taken. Scientists had hoped to see Earth in this image, but the cloudy conditions prevented a clear viewing. Similar images will be taken in the future with the hope of capturing a view of Earth. From Mars, Earth would appear as a tiny blue dot as a star would appear to an Earthbound observer. Pathfinder's imaging system will not be able to resolve Earth's moon.
The clouds consist of water ice condensed on reddish dust particles suspended in the Atmosphere. Clouds on Mars are sometimes localized and can sometimes cover entire regions, but have not yet been observed to cover the entire Planet. The image was taken about an hour and forty minutes before sunrise by the Imager for Mars Pathfinder (IMP) on Sol 16 at about 10 up from the Eastern Martian Local Horizon".

SOU-SOL039-4.jpgLIARS!!!150 visiteQuesta la sovrapposizione dei frames (1) e (3): l'immagine in verde-azzurro (dice la NASA) rappresenta il cielo del mattino ad Est, a 30 di altezza sull'orizzonte; l'immagine in rosso/rosa, invece - e sempre a detta della NASA - rappresenterebbe nuvole che si trovano ad un'altezza di 10 sull'orizzonte. La sovrapposizione ci mostra, inequivocabilmente, che i frames (1) e (3) sono, in realt, lo stesso frame. Solo che il frame (1) stato originariamente capovolto (dalla NASA) e "passato" sotto il filtro rosso.
Che tristezza. E comunque, dato che noi non pretendiamo che ci crediate sulla parola, andate a vedere Voi stessi: per il frame in versione rosa-rossa l'indirizzo :
http://marsprogram.jpl.nasa.gov/MPF/ops/sol54.html;
per il frame in verde-azzurro, invece, l'indirizzo :

Noi non siamo Scienziati, ma non siamo neppure dei poveri fessi...

SOU-SOL039-3.jpgPre-dawn clouds (3) - Sol 39123 visiteCaption NASA originale:"This true color image shows the eastern sky, 30 degrees above the horizon at 05:13 MLT on Sol 39. The bright streaks are probably ice clouds which have formed during the night. In the true colour image, the clouds appear to be blue compared to the background. This is a real effect. Unlike the red dust, the clouds are almost invisible at infrared wavelengths.
The clouds are also moving. In order to create this image, the individual, single color, data frames have had to be shifted with respect to each other. The motion indicates that the clouds are moving from the north-east to the South-West".
ATTENZIONE: questa immagine non altro che il medesimo frame, da noi rubricato come "Pre-Dawn Clouds (1)", capovolto e con filtro/colore modificato, passando dal Rosso/Rosa/Arancio al Verde/Azzurro! Ebbene, grazie all'attenzione che poniamo nell'analisi dei frames, questa volta la NASA pu solo nascondersi: li abbiamo beccati! E, se ancora non foste convinti, andate a vedere il frame che segue il quale altro non se non la sovrapposizione dei frames (1) e (3). La NASA avr anche i mezzi, ma sta MENTENDO SPUDORATAMENTE DA (almeno) 40 ANNI! E sapete queal' la cosa che pi ci meraviglia? Ma come abbiamo fatto a non accorgerci prima di una simile mistificazione?
Che pena, cari Amici, che pena...

SOU-SOL010-Twin_Peaks-TC-PIA01546_modest.jpgTwin Peaks - Sol 10 (True Colors; credits: NASA/JPL)230 visiteCaption NASA:"The True Colors of Mars based upon three filters with the sky set to aluminance of 60. The color of the Pathfinder Landing Site is yellowish brown with only subtle variations. These colors are identical to the measured colors of the Viking Landing Sites reported by Huck et al. [1977]. This image was taken near local noon (12:00 M.L.T.) on Sol 10. A description of the techniques used to generate this color image from IMP data can be found in Maki et al., 1999".
