Fienga - Lunexit Team)184 visiteNote: the THEMIS VIS camera is capable of capturing color images of the Martian Surface using 5 different color filters. In this mode of operation, the spatial resolution and coverage of the image must be reduced to accommodate the additional data volume produced from using multiple filters. To make a color image, 3 of the 5 filter images (each in grayscale) are selected. Each is contrast enhanced and then converted to a red, green, or blue intensity image.
These 3 images are then combined to produce a full color, single image BUT, since the THEMIS color filters DO NOT span the full range of colors seen by the human eye, a color THEMIS image DOES NOT represent true color. Also, because each single-filter image is contrast enhanced before inclusion in the 3-color image, the apparent color variation of the scene is exaggerated. Nevertheless, the color variation that does appear is representative of some change in color, however subtle, in the actual scene. The long edges of THEMIS color images typically contain color artifacts that do not represent or imply actual Surface Variations.

Chaotic_Terrain-Cerberus_Fossae.jpgChaotic Terrain in Cerberus Fossae (Original NASA/JPL/ASU b/w Frame)86 visiteNella Regione Marziana conosciuta con il tenebroso nome di "Cerberus Fossae" possiamo vedere, grazie a questa splendida 'veduta orbitale' ottenuta dalla Sonda NASA "2001 - Mars Odyssey", un terreno ricco di intriganti e variegati rilievi.
Qualche cratere relativamente recente (che reca segni di wind-streaks scuri) e qualcuno più antico e semi-sepolto; delle colline che sembrano poggiare sopra un "basamento" e poi - forse una delle caratteristiche più inquietanti di questo scorcio di Marte - dei profondi e scoscesi crepacci frastagliati.
Questo tipo di zona viene definito "chaos" e si tratta di un'area che è stata - letteralmente - privata di sostegno sotterraneo e che quindi è "crollata su sè stessa" (---> "Chaos" is typically interpreted to be a collapse terrain; it is the blocky landscape after the transport and removal of subsurface support).
