Coprates_Labes_Canyon-Tra_000849_1675_red~0.jpgCoprates Labes (possible True Colors; credits: Lunar Explorer Italia)106 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. MareKromium

Coprates_Labes_Canyon-Tra_000849_1675_red~1.jpgUnusual Landforms or...Something more?!?159 visiteUn ottimo lavoro di osservazione ed estrapolazione realizzato dal nostro caro Amico e Socio Lorenzo Leone ci riporta ad una (ormai) annosa e vexata questione: alcuni rilievi di Marte, nella loro "stranezza", restano rilievi naturali o si tratta di remnants di strutture artificiali?
Voi, cari Amici, la nostra posizione la conoscete; ma per questa volta - e diremmo con buona ragione - ci piace citare Lorenzo:"...Prendendo in esame una delle ultime immagini pubblicate, Coprates Labes, mi sono voluto divertire analizzandola nel tentativo di catturare le forme più strane (e sicuramente più fantasiose), ma di sicuro interesse.
Le immagini parlano da sole: abbiamo 2 possibili piramidi ed un "fortino".
Un gioco di luci ombre, aiutato da oggetti particolari, ma fantasticare e analizzare non nuoce certamente.
Ed è certo che Marte, almeno per me, riesce sempre a stupire...".
E noi condividiamo al 100%!MareKromium

Craters-Becquerel_Crater_mound_6m-00.jpgBeautiful Becquerel Crater (1)53 visiteThe mound of layered rock near the center of Becquerel Crater (2,6° North and 8,2° West) is one of the best examples of sedimentary rocks on Mars. This location has been suggested as a possible target for the 2009 Mars Science Laboratory Rover Mission. An interesting attribute of this mound is that most of the actual rock is light-toned. The darker bands seen in this image are actually dark, wind-blown sediment that has been trapped on the surface by the small escarpments associated with each layer. The source of this dark sediment is the sand dune fields to the north and south of the layered mound.
North is towards the top of the 5 images and the Sun is shining from the left.

Craters-Gale_Crater-PIA14307-PCF-LXTT.jpgCemented Fractures in the Mountain inside Gale Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)132 visiteOne type of feature of scientific interest on the mountain inside Gale Crater is exposure of Cemented Fractures, evidence that groundwater once reached to at least that height of the Mountain.
This image of that part of the mountain, taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter, shows symmetry in how material on one side of each fracture is balanced by material on the other side. This pattern indicates that mineral-saturated groundwater once filled the fractures. The water deposited minerals on both sides of the opening, eventually filling the gap.MareKromium

Craters-Gale_Crater-PIA16148-PCF-LXTT-IPF.jpgCuriosity Traverse Map through Sol 29 (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)126 visiteCaption NASA:"This Map shows the route driven by NASA's Mars rover Curiosity through the 29th Martian Day, or Sol, of the Rover's Mission on Mars (such as September 4, 2012). The route starts where the Mars Science Laboratory Spacecraft placed the Rover, a Site subsequently named "Bradbury Landing". The line extending toward the right (---> Eastward) from Bradbury Landing is the Rover's Path. Numbering of the dots along the line indicate the Sol number of each drive. North is up. The scale bar is 200 meters (656 feet).
By Sol 29, Curiosity had driven at total of 358 feet (such as 109 meters). At the location reached by the Sol 29 drive, the Rover began several Soles of Arm Characterization Activities. The "Glenelg Area", which is farther East, is the mission's first Major Science Destination, selected as likely to offer a good target for Curiosity's first analysis of powder collected by drilling into a Rock".MareKromium
