Craters-Gale_Crater-PIA14290-PCF-LXTT.jpgGale Crater (Enhanced Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)189 visiteNASA has selected Gale cCrater as the Landing Site for the Mars Science Laboratory Mission. The Rover will be placed on the ground in a Northern portion of the Crater in August 2012. This view of Gale is a mosaic of observations made in the Visible-Light portion of the Spectrum by the Thermal Emission Imaging System camera on NASA's Mars Odyssey orbiter.
Gale crater is roughly 96 miles (about 154 Km) in diameter and holds a layered mountain rising about 3 miles (approx. 5 Km) above the Crater Floor. The ellipse superimposed in this image indicates the intended Landing Area, which is 12,4 miles (about 20 Km) by 15,5 miles (about 25 Km). The portion of the Crater within the Landing Area has an Alluvial Fan likely formed by water-carried sediments. The lower layers of the nearby mountain -- within driving distance for Curiosity -- contain minerals indicating a wet history.
The intended landing site is at 4,5° South Latitude and 137,4° East Longitude.
The Mars Science Laboratory Spacecraft is being prepared for launch during the period Nov. 25 to Dec. 18, 2011. In a prime mission lasting one Martian year -- nearly two Earth years -- after landing, researchers will use the Rover's tools to study whether the landing region has had environmental conditions favorable for supporting microbial life and for preserving clues about whether life existed.MareKromium

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

Craters-Gale_Crater-PIA16240-PCF-LXTT-IPF.jpgGale Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)100 visiteThis is a 9 years' old frame taken by the NASA - MArs Odyssey Orbiter during its 11330th orbit around the Red Planet; it shows us, again (but, this time, from a slightly different position as to the one where the picture that we published yesterday was obtained), some more Features of the Floor of Gale Crater, including - once again - the Landing Site of the Mars Exploration Rover (and Laboratory) "Curiosity" (bottom right portion of the image, near the Dark Dunes), and a medium-sized Channel that cuts through the Crater's Rim (on the left side of the frame).

This frame (which is an Original Mars Odyssey Orbiter b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 16240) 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 onboard the NASA - Mars Odyssey Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.MareKromium

Craters-Gale_Crater-PIA16289-PCF-LXTT-IPF.jpgGale Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)107 visiteDuring the month of April, of the AD 2013, Mars will be in a so-called "Conjunction" relative to the Planet Earth. This means that the Sun is exactly in the line-of-(direct) sight between the two aforementioned Celestial Bodies, such as our Home Planet Earth and the Red Planet. In this Spatial Configuration, as you can easily understand, the communications between the two Planets are - in fact - almost impossible; however, during the Conjunction Period, the Rovers operating on the Surface of Mars and the Spacecrafts orbiting around it, will continue to operate, but without sending all the collected data to Earth. This data, which are all recorded and stored, will be sent to Earth when the Conjunction is over, Mars shall have moved away from behind the Sun (of course, only from our Terrestrial point of view) and therefore the line-of-(direct) sight between Earth and Mars is re-established.
During the Conjunction Period, the "NASA - THEMIS Image of the Day" will be a visual tour of Gale Crater, such as the location of the newest Mars Exploration Rover (and Laboratory) Curiosity. The first image of Gale Crater that we propose you on today's APOD (image that was taken more than 6 years ago, by the NASA - Mars Odyssey Orbiter, during its 23.897th orbit around the Red Planet) shows, among other Features, the Landing Site of the Mars Exploration Rover (and Laboratory) Curiosity (which is located approximately near the center of the image). On the other hand, the Dark Material that is visible towards the South (the lower portion of the frame), is just (Basaltic, most likely) Sand that is set on the Floor of Gale Crater in the form of Dunes; Dunes that the Curiosity Rover, in a way or another, will have to navigate through in order to get to the Layered Central Deposit (also partially visible in the frame), whose official name, as you should know by now, is "Mount Sharp".

Gale_Crater-PIA12508.jpgLayers in lower formation of Gale Crater Mound (Natural Colors; credits NASA/Dr Paolo C. Fienga - Lunexit Team)111 visiteLayers of rock exposed in the lower portion of a tall Mound near the center of Gale Crater on Mars exhibit variations in layer thickness and range between dark and light tones. The Crater's Mound of layered material is over 4 Km (approx. 2,4 miles) high, making it more than twice as thick as the stack of rocks exposed in the Grand Canyon on Earth.
Gale Crater is approx. 152 Km (about 94 miles) in diameter.
This view of layering in the Mound's lower formation covers an area about 950 meters (3100 feet) wide. It was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on April 23, 2009.
Observations of the lower formation by the Compact Reconnaissance Imaging Spectrometer for Mars, on the same orbiter, have indicated the presence of Sulfate Salts and clay minerals in these rock layers. The changes in composition from the lower (older) to the upper (younger) layers in the Gale Crater Mound may record stages in water loss and the drying out of Mars.
This image is one product from HiRISE observation ESP_012841_1750, centered at 4,9° South Lat., 137,2° East Long.MareKromium
