Spirit self-portrait (approx. true colors; credits: NASA)

Caption NASA:"The deck of NASA's MER Spirit is so dusty that the Rover almost blends into the dusty background in this image assembled from frames taken by the panoramic camera (Pancam) during the period from Spirit's Sol 1355 through Sol 1358 (Oct. 26-29, 2007). Dust on the Solar Panels reduces the amount of electrical power the Rover can generate from sunlight each Sol. Earlier self-portraits by Spirit, such as one taken on Sol 586 (PIA03272), offer a comparison view of cleaner Solar Panels.
The vertical projection used here produces the best view of the Rover deck, though it distorts the ground and antennas somewhat. The eight-pointed star shape near the front of the Rover (bottom of the image) marks the location of the Camera MAST, which is out of view of the PanCam atop the MAST.

This mosaic view in approximate true color is a composite of frames taken through the PanCam's filters centered on wavelengths of 600, 530 and 480 nanometers".

Nota Lunexit: un esempio di quanto sìano brutte, malfatte e (sostanzialmente) insignificanti le "interpretazioni cromatiche" della NASA. Difficile dire il motivo di siffatta pochezza. Diciamo che, forse, non hanno voglia di impegnarsi sui "colori" e quindi spacciano per "scientifiche ricostruzioni in approx. true colors" quelle che sono solo delle orribili (e distratte) colorizzazioni fatta usando un Software comune...
