PSP_010206_1975_RED_abrowse-00.jpgAncient Bedrock and Megabreccia in Nili Fossae region (ctx frame - possible True Colors; credits: Lunexit)77 visiteThis image captures a record of changing environments on ancient Mars, as recorded in the rock record at Nili Fossae.
In addition to Megabreccia (see the edm that follows), the image shows layered rocks which have been shown by the orbiting spectrometers OMEGA and CRISM to contain Clay minerals. These minerals must have formed in the presence of water, and may have later been transported and deposited here in sedimentary layers.
Most of the layers appear to overlie the exposures of Megabreccia, but some Megabreccia blocks are themselves internally layered, suggesting that sedimentary processes were active here early in Martian History.
Above the clay-bearing layers is a dark, rough-textured rock unit that was emplaced later. Geologic mapping of the Nili Fossae Region has shown this deposit to be a Lava Flow from the Syrtis Major Volcano to the South. The minerals detected in the Lava Flow suggest that liquid water had become rare on the Martian Surface by the time the flow occurred.MareKromium

Echus_Chasma-398-260508-2204-6-co-01-H1.jpgEchus Chasma (False Colors)68 visiteThe High-Resolution Stereo Camera (HRSC) on board ESA's Mars Express has returned images of Echus Chasma, one of the largest Water Source Regions on the Red Planet.
The data were acquired on September, 25, 2005.
The pictures are centred at about 1° North and 278° East and have a ground resolution of approx. 17 mt/pixel.
Echus Chasma is an approx. 100 Km long and 10 Km wide incision in the Lunae Planum High Plateau North of Valles Marineris, the "Grand Canyon" of Mars. Echus Chasma is the Water Source Region of Kasei Valles, which extends thousands of Km to the North, and its southern-most part. The images of the Echus Chasma plateau show valleys that are about 10 km long and 1000 m deep. The main valley, Kasei Valles, is about 4 km in depth. The smaller valleys, also called sapping canyons, originate from the discharge of groundwater.
Echus Chasma is bounded to the West by the Echus Chasma Plateau, which lies about 4 Km above Echus' floor. MareKromium

OPP-SOL1095-1P225391403EFF79R1P2372L2M1~0.jpgThe "Inner Walls" of Victoria (HR and digitally cleaned) - Sol 109565 visiteVersione a colori elaborati da Lunexit sulla base di quanto ottenuto dalla NASA con le vedute orbitali MRO. Frame digitalmente ripulito (la NASA ha ormai maturato questa sgradevolissima abitudine di proporre i frames con pixellatura evidente e grossolana la quale, anche con un minimo stretch dell'immagine, produce la "sgranatura" di tutto quanto ripreso).
Noi ci proviamo a "ripulire" ma...se lo facessero loro (visti i mezzi che hanno e che dicono di avere...) sarebbe meglio!MareKromium

PSP_006681_1580_RED_abrowse~0.jpgFresh Southern Crater (natural colors; credits: Lunexit)106 visiteThis image features a very fresh crater in the Southern Hemisphere. The crater is termed fresh because it is well-preserved with steep walls and obvious small-scale ejecta.
The crater has a set of dark rays extending from it; these rays are ejecta that sprayed out when the crater formed. Boulders ejected during the impact surround the crater.

ZZ-ColorMars-07-KL-H1201whiterockcolorwebth.jpgMars from Orbit, as a "Human" would see it...by Keith Laney (1)85 visiteUn omaggio di Lunar Explorer Italia al bravissimo Keith Laney (http://keithlaney.net/) il quale, già molto tempo prima di noi, aveva iniziato a colorizzare i frames orbitali NASA ottenendo - come si vede in queste quattro immagini (e come potrete ammirare nella Galleria predisposta sul suo Sito) - dei risultati splendidi, realistici e, probabilmente, alquanto accurati.
A nostro avviso il Lavoro di Keith è davvero bellissimo e meritevole della massima considerazione; una sola "pecca" (veniale, a nostro parere): allo scopo di offrire il "meglio del meglio" ai Lettori, il bravissimo Keith si è "dimenticato" della vaga ma persistente foschia che "appanna", leggermente, tutti i rilievi superficiali inquadrati dall'orbita. Le sue elaborazioni, infatti, sono sempre super-nitide, super-definite e con contrasti e colori perfetti.
Elaborazioni bellissime, quindi, ma che fanno assomigliare Marte, in qualche caso, ad una sorta di diorama più che ad un Mondo reale.
Comunque complimenti - detto di cuore - a Keith Laney: ottimo lavoro!MareKromium
