Chasma-Echus_Chasma-Fractures-PIA17704-PCF-LXTT-IPF.jpgFeatures of Echus Chasma (EDM - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)96 visiteIn this Extra Detail Magnification (or "EDM" for short) - taken from an Original NASA - Mars Reconnaissance Orbiter's False Colors and NON-Map Projected sub-frame -, we can see, with a really great detail, a so-called "Intersection Area" existing between two Fractures (or, perhaps, Fissures and/or Water or Lava-carved narrow Channels) which are both located on the Floor of Echus Chasma (an Equatorial Chasma found in the Lunae Planum High Plateau Region of Mars, slightly to the North of the gigantic Valles Marineris Canyon System, and approx. 100 Km long and 10 Km wide).
Echus Chasma contains several Valleys which range - as far as their depth is concerned - from about 1 to 4 Km, and it is now considered, by Planetary Scientists, to be the Water Source Region that allowed the formation and then the (relevant) water-supply of the Kasei Valles Outflow Channel: a large Valley that extends for thousands of kilometers towards the North of the Red Planet.

This picture (which is a crop taken from a NASA - Original Mars Reconnaissance Orbiter False Colors and NON-Map Projected sub-frame identified by the serial n. ESP_033591_1805-1) has been additionally processed, magnified, contrast enhanced, Gamma corrected, and then re-colorized 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.MareKromium

Echus_Chasma-398-260508-2204-6-co-01-H1.jpgEchus Chasma (False Colors)54 visiteThe High-Resolution Stereo Camera (HRSC) on board ESA’s Mars Express has returned images of Echus Chasma, one of the largest Water Source Regions on the Red Planet.
The data were acquired on September, 25, 2005.
The pictures are centred at about 1° North and 278° East and have a ground resolution of approx. 17 mt/pixel.
Echus Chasma is an approx. 100 Km long and 10 Km wide incision in the Lunae Planum High Plateau North of Valles Marineris, the ‘Grand Canyon’ of Mars. Echus Chasma is the Water Source Region of Kasei Valles, which extends thousands of Km to the North, and its southern-most part. The images of the Echus Chasma plateau show valleys that are about 10 km long and 1000 m deep. The main valley, Kasei Valles, is about 4 km in depth. The smaller valleys, also called sapping canyons, originate from the discharge of groundwater.
Echus Chasma is bounded to the West by the Echus Chasma Plateau, which lies about 4 Km above the Echus Chasma floor. MareKromium
