PSP_003249_1510_RED_browse_00~0.jpgLayered Deposits in Ritchey Crater (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)65 visiteThis HiRISE image shows eroding layered deposits in Ritchey Crater, a large impact crater in the Southern Highlands.
Three general units can be seen: a relatively dark upper layer, a light middle unit, and the floor material, which may be mostly obscured by dust.
The dark cap layer appears to be relatively hard and resistant, while the light material is weak.
Once the upper layer is removed, the light layer does not last long.
It is unclear how each of these layers formed.
Volcanic ash layers, lake or stream deposits, or sandstone deposited by dunes can all produce horizontal layers. Unraveling the origin would provide important clues to Mars' past.MareKromiumGen 22, 2009

This cutout from the top center part of the context image shows this stack.
The dark unit is thin and breaking into boulders. The light material is actually divided into smaller layers, and is pervasively fractured. However, the boulders falling from the edge are mostly small and rarely remain intact if they move more than a few meters.
The cracking of the layer could be due to water loss from the layer, or to regional tectonic effects such as stresses from burial and erosion.
The base unit is partially covered by wind-blown ripples.MareKromiumGen 22, 2009

MartianTerminator-TRA_000841_1300_RED.jpgHalf in the light and half in the darkness... (possible True Colors; credis: Lunar Explorer Italia)59 visiteCaption NASA originale:"Image TRA_000841_1300 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on October 1, 2006. The complete image is centered at 49,7° South Lat. and 154,2° East Long. The range to the target site was 248,4 Km (such as about 155,3 miles).
At this distance the image scale is 99,4 cm/pixel (with 4 x 4 binning) so objects ~298 cm across are resolved. The image shown here has been map-projected to 100 cm/pixel and North is up. The image was taken at a MLT of 15:39 and the scene is illuminated from the West with a solar incidence angle of 87°, thus the Sun was about 3° above the horizon.
At a Solar Longitude of 114,2°, the season on Mars is Northern Summer". MareKromiumGen 22, 2009

Chasma_Boreale-Psp_001412_2650_red-00~0.jpgChasma Boreale: the Martian "Pentagon" and other unusual surface features (1)123 visiteUn modestissimo esempio (si fa per dire...) di Anomalìa di Superficie sul Pianeta Rosso: siamo nella Regione conosciuta come Chasma Boreale. Un frame bello, senza dubbio, ma privo di interesse.
Privo di interesse?!? Ne siamo/siete certi?!?
Ma no, certo che no! Basta un minimo di "occhio" e di attenzione, infatti, per scoprire alcuni rilievi che non hanno davvero nulla di usuale e che, quindi, sono interessanti per definizione.
Eccoli qui (dall'alto in basso):
1) un doppio cratere da doppio impatto (...sic...) - a forma di "8" - con/su "piedistallo";
2) un cratere a forma PENTAGONALE (quasi) REGOLARE e
3) un rilievo ad ANGOLO RETTO (che abbiamo definito "L-shaped") all'interno di un altro cratere.
Ora, a noi vanno bene gli Scrittori di Fantascienza (tipo Hoagland e Discepoli) i quali vedono manufatti ed artificialità ovunque, però ci sorprende che questi "Fenomeni" non riescano a vedere delle Anomalìe di simile portata! Insomma: costoro vedono le "pagliuzze", ma NON VEDONO LE TRAVI!!!
Certo, parlare di "piramidi" ed altre scemenze simili fa audience&business, siamo d'accordo. Ma allora - per favore - smettetela di dire che "cercate la Verità"!
La Verità è che di rilievi (a dir poco) anomali, su Marte (e non solo), ce ne sono migliaia e non si tratta, purtroppo per Voi, delle solite "facce" e delle immancabili "piramidi". Si tratta di rilievi i quali FANNO A PUGNI con la Geologia Convenzionale, le Meccaniche da impatto e tanti altri precetti della Scienza Consolidata. Quella Scienza che viene usata solo quando fa comodo e solo da coloro che possono disporre del supporto di mezzi di comunicazione di massa.
Volete parlare di Anomalìe Marziane? Guardate questo frame ed il successivo detail mgnf! Non c'è bisogno di Cydonia & dintorni (o delle pseudo-fotografie ESA) per porsi delle domande "intelligenti, affascinanti ed indiscrete"...MareKromiumGen 22, 2009

Coprates_Labes_Canyon-Tra_000849_1675_red~0.jpgCoprates Labes (possible True Colors; credits: Lunar Explorer Italia)109 visiteCoprates Labes is a Martian canyon, part of the huge Valles Marineris System. Valles Marineris most likely formed through tectonic processes, with extensional stresses leading to collapse of the terrain that now lies at the base of the canyons. Filling most of this image, we see a raised block on the canyon bottom, which is quite possibly a horst—a block bounded by faults that separate it from sunken blocks on each side. The raised block is heavily eroded, possibly by wind; this erosion has exposed its internal layering, especially at the Southeastern margin of the block.
Here we see asymmetric erosion features with shallow slopes trailing off to the North-West, suggesting that southeasterly winds dominate the flow through this Region. The arrangement of dunes and ripples in the lower right portion of the image confirms this prevailing wind direction.
Finally, dark-toned material appears to have flowed from North-East to South-West along the block, possibly moving in a very fluid debris flow. MareKromiumGen 22, 2009

PSP_004071_1425_RED_browse-01.jpgMesas in Gorgonum Chaos (edm - possible True Colors; credits: Lunar Explorer Italia)57 visitePSP_004071_1425 shows mesas that are part of Gorgonum Chaos, a region of chaotic terrain, which is a jumble of mounds and mesas grouped together.
Chaotic terrain is most commonly found in Mars near the sources of the gigantic outflow channels. Gorgonum Chaos is one of the few exceptions.
Some of the troughs between the mesas appear to have V-shaped bottoms; there is no obvious flat floor in between. Others have dunes running down their centers probably indicating flat floors. It is possible that the mesas were once connected and that something caused fractures in the original mesa's surface that were then preferentially eroded.MareKromiumGen 20, 2009
