A R C H I V E S

A South-facing Escarpment located in the North/Western part of the Martian Region known as Hellas Planitia (a target that was chosen for the research of Phyllosilicates) showed us the presence, inside the Rocks (---> mostly in their horizontal cracks) forming it, of a pale bluish Material, barely visible in this Absolute Natural Color image (in the EDM, to be precise). The CRISM Spectra of such Material showed that it consists of a combination of Chlorite and Water Ice. This image was captured by the NASA - Mars Reconnaissance Orbiter during the Southern Martian Winter, such as in the time period when the Southern Hemisphere's South-facing Escarpments (just like this one) of the Red Planet retain Water Ice Deposits that formed during that dark, long and extremely cold Season.

Mars Local Time: 15:36 (Middle Afternoon)
Coord. (centered): 26,501° South Lat. and 55,094° East Long.
Spacecraft altitude: 268,2 Km (such as about 166,552 miles)
Original image scale range: 26,8 cm/pixel (with 1 x 1 binning) so objects ~ 80 cm across are resolved
Map projected scale: 25 cm/pixel
Map projection: EQUIRECTANGULAR
Emission Angle: 18,0°
Phase Angle: 56,7°
Solar Incidence Angle: 69° (meaning that the Sun was about 21° above the Local Horizon at the time the picture was taken)
Solar Longitude: 131,4° (Northern Summer - Southern Winter)

Additional process. and coloring: Lunar Explorer Italia

These picturees (which are a NASA - Original Mars Reconnaissance Orbiter NON-Map Projected b/w frame and a false color EDM, identified by the serial n. ESP_027758_1530 and ESP_027758_1530-1) have been additionally processed, magnified to aid the visibility of the details, contrast enhanced and then colorized (and re-colorized, respectively) in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Reconnaissance 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.
