Candor_Chasma-03.jpgCandor Chasma from MGS and 2001 Mars Odyssey83 visiteCaption originale:"The 2001 Mars Odyssey Spacecraft includes an imaging device called THEMIS which scans strips of Mars in various wavelengths. Although numerous excellent images have been returned, unfortunately quirks and light leak defects in the camera system prevent straightforward registration of images obtained in different wavelengths. The first RGB color image released from Mars Odyssey is shown in the context of a color image from Mars Global Surveyor with a faked green channel. The THEMIS image appears too dark and saturated to me but I have preserved the color balance as released. Detailed criticism must be qualified by knowledge of the heroic measures taken to 'rescue' this RGB color image. The dark gray terrain in the valley floor shows as brownish to olive greenish in the closeup, and an orange region in the lower right is seen as the edge of a larger reddish area in the central interior of Candor Chasma".Apr 09, 2006

The lighter layer appears to be on top (therefore younger) than the darker surface".

South_Polar_Regions-Clouds-PIA02171-2.jpgClouds (RAW and b/w NASA Original Frame)56 visiteIn questa immagine si possono vedere delle sottili (quasi trasparenti...) formazioni nuvolose che sovrastano le Regioni Presso-Sud Polari di Marte. L'evidente sottigliezza delle nuvole è indicativa della circostanza per cui esse dovrebbero essere composte in larga prevalenza da ghiaccio d'acqua. Da ricordare, quindi, che le formazioni nuvolose "spesse", su Marte, sono invece prevalentemente costituite da polveri.
