Volcanoes-Olympus_Mons-PCF-LXTT.jpgOlympus Mons and Surroundings (Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)69 visiteUna nostra elaborazione Multispettrale del maestoso Vulcano Olympus, ottenuta da un frame HR proveniente dalla Sonda ESA "Mars Express".
Caption ESA:"This is a mosaic of Olympus Mons, the highest volcano on Mars, which towers 26 Km above the surrounding plains. The image covers an area of approx. 600.000 sq/km.
The High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express Orbiter imaged the Region over 18 orbits.
This image is an ortho-image mosaic, where the projecting rays are perpendicular to the plane of projection.
This corrects any deformations introduced by an imaging camera and therefore such an image can be fitted directly on to a map.
From the observations, 16 HRSC orbit strips, with around 35 Gigabytes of data were used to generate a Digital Terrain Model (DTM) mosaic and an ortho-image mosaic. The DTM mosaic has a resolution of 150 mt/pixel. The resolution of individual nadir images (taken by pointing the camera vertically down to the surface) is in the range of 12 to 40 mt/pixel. Individual terrain models with a resolution of up to 50 mt were derived for every HRSC image strip.
The HR DTMs and ortho-images are derived through a complex process. Matching surface features were used to 'stitch' the images strips together, and complex geometrical calculations were used to produce the 3D coordinates of all measured points in the area".MareKromium

Echus_Chasma-398-260508-2204-6-co-01-H2.jpgHigh Cliffs Surrounding Echus Chasma on Mars69 visiteWhat created this great cliff on Mars? Did giant waterfalls once plummet through its grooves? With a four-kilometer drop, this high cliff surrounding Echus Chasma, near an impressive impact crater, was carved by either water or lava. A leading hypothesis is that Echus Chasma, at 100-Km long and 10-Km wide, was once one of the largest water sources on Mars. If true, water once held in Echus Chasma likely ran over the Martian Surface to carve the impressive Kasei Valles, which extends over 3000 Km to the North. Even if initially carved by water, lava appears to have later flowed in the valley, leaving an extraordinarily smooth floor. Echus Chasma lies north of tremendous Valles Marineris, the largest canyon in the Solar System. The above image was taken by the robotic Mars Express spacecraft currently orbiting Mars.
Nota Lunexit: checchè ne dica la NASA, questo frame NON E' una fotografia.MareKromium

Claritas_Fossae-4-096-140904-0508-6-co-01-ClaritasFossae_hires.jpgClaritas Fossae (4 - ESA/ DLR/ FU Berlin - G. Neukum)67 visiteCaption ESA originale:"The lava blankets of the Solis Planum area cover the eastern parts of the older Claritas Fossae ridge and surround some of the higher ground. The geological history of this region can be reconstructed by analysing the layers of tectonic grabens, impact craters, volcanic features and even small valley networks. The complexity of Claritas Fossae Region suggests that some of the events took place at the same time. Furthermore, the detailed view of the large southern impact crater shows patches of dark material which are located near the central and marginal parts of the impact crater floor. This material may be of volcanic origin".

Neukum))66 visiteOriginal ESA caption:"This image taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, shows the Biblis Patera Volcano, located in the Western part of the Tharsis rise on Mars.
The HRSC obtained this image on 8 November 2004 during orbit 1034 with a ground resolution of approx. 10,8 mt per pixel. Its shows the region of Biblis Patera at approx. 2,0° North and 236,0° East.
North is to the right".

RupesTenuis-428-20081205-5872-6-co-01-RupesTenuis_H1.jpgNorth Polar Features: Rupes Tenuis (Natural Colors; credits: Lunar Explorer Italia)66 visiteCaption ESA:"ESA’s Mars Express Orbiter imaged the snow-laden region of Rupes Tenuis on the Martian North Pole on July, 29th, 2008.
Rupes Tenuis is located at the southern edge of the Martian North Polar Cap, approx. 5500 Km North-East of the Tharsis Province.
The image shows an area located at about 81° North Lat. and 297° East Long. and has a ground resolution of approx. 41 mt/pixel. It covers an area of about 44.000 Km2 (such as almost as large as the Netherlands)".
Nota Lunexit: secondo noi, questa "immagine" (che in realtà dovrebbe essere un fotomosaico) NON E' reale. L'immagine...NON E' un'immagine reale di Marte (è solo una ricostruzione virtuale, nello stile tipico della - sempre più ambigua e sopravvalutata - ESA). MareKromium

Craters-Lauth_Crater_in_Vastitas_Borealis_Region-Frozen_Lake-W-212-010705-1343-6-3d-01-03.jpgThe misterious "Frozen Lake" of Vastitas Borealis (4 - Extremely Enhanced Natural Colors; credits for the additional process. and color.: Lunar Explorer Italia)65 visitePiena Estate Polare Marziana: polveri rosse ricoprono il cratere senza nome di Vastitas Borealis e colorano, in parte, il suo "laghetto" centrale.
Da notare che, in accordo alle nostre assunzioni di partenza (ed in accordo a regole elementari di logica e di buon senso), un cielo ricco di polveri color arancio, gialle e rossastre (e dunque, di conseguenza, un cielo color rosso/arancio e giallo - di base) si dovrebbe adeguatamente riflettere con questi medesimi colori nelle acque - a questo punto ghiacciate o meno diventa indifferente - del lago di Vastitas.
Ebbene, la regola elementare per cui le acque e/o i ghiacci superficiali, "usualmente", riflettono il colore del cielo, nel frame ESA Originale (fateci caso!) diremmo che NON trova applicazione.
Come mai? Forse abbiamo sbagliato noi...O forse l'immagine ESA è un'mmagine bella ma fasulla? O forse i suoi colori sono stati taroccati (male)?
O magari essa è frutto di incompetenza?
Oppure - chissà... - l'immagine ESA di partenza è un mix di tutte e tre le possibili (e summenzionate) variabili... Decidetelo Voi.MareKromium
