Dusty Cape Verde
The
Opportunity rover acquired this mosaic of Cape Verde on Sol 1570 (June
23, 2008). Cape Verde was one of several bedrock promontories along the rim of Victoria Crater that Opportunity studied. It is about 6 meters (20 feet) tall. The title for this
mosaic refers not to Cape Verde itself, but to the fact that the left
side of Pancam's front sapphire windows had, at this point in the mission, picked up a
good bit of dust. Subframing the individual images helped mitigate
the problem, but the mosaic still shows evidence of the dusty window in
the slightly washed out look (caused by light scattered by the dust) and
the visible seams (caused by differences in the right and left sides of
joining images).
The mosaic's field of view is about 40 degrees across and about 35
degrees high.
This mosaic was acquired in
Pancam's 753-nm, 535-nm, and 432-nm filters. Two versions are offered
here at full resolution: an approximate true color rendering, and a
false color stretch to bring out subtle color differences in the scene.
