The "Trenches" - Sol 145 (False Colors; credits: NASA)

...Tanto per far vedere la "differenza" fra il processing NASA e quello Lunexit...

Caption NASA:"The Surface Stereo Imager on NASA's Phoenix Mars Lander took this false color image on Oct. 21, 2008, during the 145th Martian Day, or Sol, since landing. The bluish-white areas seen in these trenches are part of an ice layer beneath the soil.
The trench on the upper left, called "Dodo-Goldilocks", is about 38 cm (15") long and 4 cm (1,5") deep.
The trench on the right, called "Upper Cupboard", is about 60 cm (24") long and 3 cm (1") deep. The trench in the lower middle is called "Stone Soup".
