Features of Echus Chasma (EDM - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)
In 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.

Mars Local Time: 14:36 (Early Afternoon)
Coord. (centered): 0,377° North Lat. and 279,483° East Long.
Spacecraft altitude: 269,1 Km (such as about 161,111 miles)
Original image scale range: 53,8 cm/pixel (with 2 x 2 binning) so objects ~ 1 mt and 62 cm across are resolved
Map projected scale: 50 cm/pixel
Map projection: EQUIRECTANGULAR
Emission Angle: 7,7°
Phase Angle: 47,6°
Solar Incidence Angle: 40° (meaning that the Sun was about 50° above the Local Horizon at the time the picture was taken)
Solar Longitude: 27,0° (Northern Spring - Southern Fall)

Additional process. and coloring: Lunar Explorer Italia

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.

Canyon creati dall'erosione dell'acqua. Credo che non ci siano dubbi su questo. Vero?

l'origine potrebbe essere anche tettonica, ma sicuramente in tali lineazioni si è impostato un corso d'acqua....

...ed infatti la NASA, tanto per non smentirsi mai, ha "statuito" che sono canali di origine chiaramente lavica.... Guardate, alle volte veramente mi sento un idiota, perché o io non ho capito nulla (e continuo a non capire nulla), oppure anche le Scienze Planetarie sono un "prodotto opinabile"... Mah. Sono felice che siate intervenuti: GRAZIE di Cuore! paolo
