SOL0139-PIA16706-PCF-LXTT-IPF.jpgSpherules at Gale Crater - Sol 139 (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)89 visiteCaption NASA:"This image from the Right Mast Camera (MastCam) onboard the NASA - Curiosity Mars Exploration Rover shows roughly Spherical Features, which are VERY similar to the ones found by the Mars Exploration Rover Opportunity in the Meridiani Planum Region of Mars. These "Gale Crater's" Spherules are apparently common in this Stratigraphic Unit, informally "Sheepbed"; a Stratigraphic Unit which defines the lower part of the sequences of Strata exposed in the area known as "Yellowknife Bay". These Spherical Features have been interpreted as "Concretions": a definition which implies that they have formed in Water that percolated (---> the movement and filtering of fluids through porous materials) through the Sediment. Curiosity's MastCam obtained these images on the 139th Martian day, or Sol, of the Rover's Surface Operations at Gale Crater (such as December, 25th, 2012)". MareKromiumGen 18, 2013

SOL0120-PIA16707-PCF-LXTT-IPF.jpg"Shaler Unit" - Sol 120 (Slightly Darkened Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)67 visiteCaption NASA:"This image from the Mast Camera (MastCam) onboard NASA's MER Curiosity shows a bizarre-looking Stratigraphic Unit (known as "Cross-Bedding") located in an Outcrop called "Shaler". This Stratigraphic Unit has been informally dubbed "Shaler Unit". This kind of "Cross-Bedding" in the Shaler Unit is indicative of Sediment transport in Stream Flows. Currents mold the Sediments into Small Underwater Dunes that migrated downstream. When exposed in cross-section, evidence of this Migration is preserved in the form of Strata that are steeply inclined as to the Bed (---> River or Lake's Floor) they lay on (thus the term "Cross-Bedding." The grain sizes here are coarse enough to exclude an Aeolian transport.
This Cross-Bedding occurs stratigraphically above the Gillespie Unit located in the "Yellowknife Bay" area of Gale Crater, and is therefore geologically younger. The MastCam obtained the image on the 120th Martian day, or sol, of Curiosity's Operations (such as December, 7th, 2012).MareKromiumGen 18, 2013

SOL0133-PIA16564-PCF-LXTT-IPF.jpgSnake River - Sol 133 (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)91 visiteThe sinuous Rock Feature visible in the lower center and left (Sx) side of this mosaic of frames recorded by the NASA - Mars Exploration Rover (MER) - Mars Laboratory "Curiosity" has been nicknamed "Snake River" (and we honestly believe that, once you notice the actual physical configuration of the Rocky Feature that is now under a - relatively - close observation, the reason of the nickname will result more than obvious...).
The images forming the mosaic were taken by Curiosity's Navigation Camera (NavCam) during the 133rd Martian Day, or Sol, of the Rover's Mission in Gale Crater - Mars (such as December, 20th, 2012). On Sol 147 (such as January, 3rd, 2013), the NASA - Mars Exploration Rover (MER) - Mars Laboratory "Curiosity" drove about 10 feet (approx. 3 meters) to get a closer look at "Snake River", before proceeding to watch, photograph and then examine other Rocky Features located in the same area as well as in other areas nearby.
This picture (which is an Original NASA - Mars Exploration Rover - Mars Laboratory "Curiosity" b/w image-mosaic published on the NASA - Planetary Photojournal with the ID n. PIA 16564) has been additionally processed and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were near the NASA - Mars Exploration Rover (MER) - Mars Laboratory "Curiosity" and then looked ahead, towards the Rocky Surface Feature called "Snake River", the Rocky Paving located in front of and around the Rover, as well as the more distant Horizon of Gale Crater), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among other things, the existence of different Elements (Minerals) present on the Surface of Gale Crater, each having a different Albedo (---> Reflectivity) and Chemical Composition.MareKromiumGen 11, 2013
