PrometheiPlanum.jpgPromethei Terra (Natural Colors + MULTISPECTRUM; credits: ESA & Lunexit)64 visitePromethei Planum, an area seasonally covered with layer of ice more than 3500 mt thick layer of ice in the Martian South Polar Region, was the subject of the High Resolution Stereo Camera’s focus on 22 September 2005 as Mars Express was in orbit above the Red Planet.
Promethei Planum lies at approx. 76° South Lat. and 105° East Long.
An approx. 100 Km-large and 800 mt-deep impact crater is visible in the Northern part of the image. The crater’s interior is partly covered in ice.
In the centre of the image are structures that may have been created by basaltic lava flow from a volcano. This area is covered in ice. The dark dunes towards the bottom of the image are most likely made up of dust originating from this lava flow or volcanic ash.
A broad sheet of ice, which is an extension of the South Polar Ice Cap is located South of the lava flow. The steep flanks clearly show white, clean ice. The thickness of the ice is between 900 and 1100 mt.MareKromium

Craters-Lauth_Crater_in_Vastitas_Borealis_Region-Frozen_Lake-W-212-010705-1343-6-3d-01-00.jpgThe misterious "Frozen Lake" of Vastitas Borealis (1 - Natural Colors; credits ESA)75 visiteCaption ESA:"The HRSC on ESA's Mars Express obtained this perspective view on 2 February 2005 during orbit 1343 with a ground resolution of approximately 15 mt per pixel. It shows an unnamed impact crater located on Vastitas Borealis, a broad plain that covers much of Mars's far Northern Latitudes, at approx. 70,5° North Lat. and 103° East Long.
The crater is about 35 Km wide and has a maximum depth of approx. 2 Km beneath the crater rim. The circular patch of bright material located at the centre of the crater is residual water ice.
The colours are very close to natural, but the vertical relief is exaggerated three times. The view is looking East".
Nota: noi crediamo che questo cratere sia molto più enigmatico di quanto non appaia poichè, pur avendo esaminato tutti i frames NASA-MGS relativi alla Regione di Vastitas Borealis (in particolare quelli rapprsentativi dell'area suggerita dalle coordinate ESA), non ci è riuscito di individuare il "laghetto ghiacciato".
Il cratere senza nome che lo dovrebbe contenere, poi, appare solo una volta - e solo in una veduta PARZIALE! - in un frame NASA-Mars Odyssey che Vi proporremo qui di seguito.
Infine, i "colori naturali" di Vastitas Borealis, in accordo ai dati NASA disponibili (i quali sono anche comprensivi di informazioni ottenute sia attraverso vedute telescopiche HST, sia attraverso osservazioni effettuate da Terra), dovrebbero essere molto diversi da quelli suggeriti dall'ESA (noi Vi proporremo tre elaborazioni al riguardo).

South_Polar_Regions-Rupes_Tenuis-ESA-PF.jpgRupes Tenuis (possible Natural Colors; credits ESA - additional color. and process. Dr Paolo C. Fienga)80 visiteESA’s Mars Express orbiter imaged the snow-laden Region of Rupes Tenuis on the Martian North Pole on 29 July 2008.
Rupes Tenuis is located at the Southern Edge of the Martian North Polar Cap, approx. 5500 Km northeast of the Tharsis Volcanic Region.
The images are at about 81° north and 297° east and have a ground resolution of approx. 41 mt/pixel. They cover an area of about 44.000 square/Km, almost as large as the Netherlands.
Nota Lunexit: a nostro avviso questa "immagine" NON E' VERA! E' un disegno. Al limite, è la trasposizione digitale di un frame RAW originale unprocessed (ma ne dubitiamo).MareKromium

Deuteronilus_Mensae_Region-PCF-LXTT.jpgDeuteronilus Mensae (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia64 visiteThis image shows the Deuteronilus Mensae Region on Mars, an area primarily characterized by (peri)glacial features.
It was taken on 14 March 2005 (orbit number 1483) by the High Resolution Stereo Camera (HRSC) onboard ESA's Mars Express with a ground resolution of approx. 29 mt per pixel.
The area is located on the Northern edge of Arabia Terra and borders the Southern High- and Northern Lowlands, at approx. 39° North Lat. and 23° East Long. MareKromium
