Luna17-Video.jpgThe "Nest" of Lunokhod-1 (video picture)171 visiteOver 20.000 low-resolution (LR) video pictures were transmitted by Luna 17, primarily for use by the drivers to navigate the Rover. Note the usual horizontal scanlines of a TV camera, as opposed to the vertical scanlines of the cycloramic cameras.

PSP_010012_2225_RED_abrowse-00.jpgDeep Rocks Unveiled at Bonestell Crater (ctx frame; natural colors; credits: Lunexit)54 visiteImpact craters are sometimes nicknamed “Mother Nature's drill holes” because, thanks to them, deep rock formations are exposed at the surface. Bonestell Crater is a good example.
This image depicts part of the floor of this relatively young impact crater located in the Northern Lowlands. The Northern Lowlands occupy most of the northern half of Mars. They are younger than the Southern Highlands, as shown by the lower number of impact craters, and well below the Planet’s Average Elevation. Their origin is still a mystery.
Bonestell is about 42 Km (approx. 26 miles) in diameter and about 1250 meters (4100 feet) deep. The rocky hills on the floor of this crater constitute its “Central Peak”.
Central peaks form due to elastic rebound of subsurface materials immediately after impact. The rocks in Bonestell's Central Peak may have been 4-to-8 Km below the surface before impact.MareKromium

PSP_010012_2225_RED_abrowse-01.jpgDeep Rocks Unveiled at Bonestell Crater (edm; natural colors; credits: Lunexit)53 visiteThis edm (437x500 mt or 479x547 yards) of the HiRISE image shows a portion of Bonestell's Central Peak. HiRISE reveals details in the structure and color of these deep rocks that will help scientists decipher the origin and history of the Northern Lowlands.MareKromium

SOL0052-PIA16204-PCF-LXTT-IPF.jpg"Rocknest" Site - Sol 52 (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunar Explorer Italia/Italian Planetary Foundation)101 visiteCaption NASA:"This patch of windblown Sand and Dust downhill from a cluster of Dark Rocks is the so-called "Rocknest" Site, which has been selected as the likely location for first use of the scoop on the Robotic Arm of NASA's Mars Exploration Rover Curiosity. This view is a mosaic of images taken by the telephoto right-eye camera of the Mast Camera (Mastcam) during the 52nd Martian Day, or Sol, of the mission (such as September, 28, 2012). Just 4 (four) Soles before, the Rover arrived at Rocknest. The "Rocknest" patch is about 8 by 16 feet (such as approx. 1,5 by 5 meters)".MareKromium

SOL0059-PIA16452-PCF-LXTT-IPF.jpgRocknest 3 - Sol 59 (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)86 visiteThis view of a Martian Rock nicknamed "Rocknest 3" combines 4 (four) images taken by the right-eye camera of the Mast Camera (MastCam) Instrument located onboard the NASA - Mars Exploration Rover - Mars Laboratory "Curiosity", which has a telephoto, 100-millimeter-focal-length lens. The component images were taken a few minutes after Martian noon (---> 12:00 Mars Local Solar Time) on the 59th Martian Day, or Sol, of Curiosity's operations at Gale Crater, Mars.
Rocknest 3 is a Sedimentary Rock approximately 15" (such as about 40 centimeters) long and about 4" (approx. 10 centimeters) tall; next to "Rocknest 3" there is a patch of windblown Dust and Sand where Curiosity scooped and analyzed several Soil Samples. The MastCam was about 13 feet (approx. 4 meters) from Rocknest 3 when the component images were taken, thus providing an image scale of about 0,01" (approx. 0,3 millimeter) per pixel.
This picture (which is an Original NASA - Mars Exploration Rover - Mars Laboratory "Curiosity" white-balanced color frame published on the NASA - Planetary Photojournal with the ID n. PIA 16452) has been additionally processed and then re-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 down, towards the Rock known as Rocknest 3), 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.MareKromium
