Deflated Airbags and Skyline - Soles 8, 9 and 10 (Natural Colors; credits: NASA/JPL)

Caption NASA originale:"This is a sub-section of the geometrically improved and color enhanced version of the 360° panorama known as the "Gallery Pan", the first contiguous, uniform panorama taken by the Imager for Mars Pathfinder (IMP) over the course of Soles 8, 9 and 10. Different regions were imaged at different times over the 3 Martian days to acquire consistent lighting and shadow conditions for all areas of the panorama.
The IMP is a stereo imaging system that, in its fully deployed configuration, stands 1,8 mt above the Martian surface and has a resolution of 2 mm at a range of 2 mt. In this geometrically improved version of the panorama, distortion due to a 2,5° tilt in the IMP camera mast has been removed, effectively flattening the horizon. The IMP has color capability provided by 24 selectable filters -- twelve filters per "eye". Its red, green, and blue filters were used to take this image. The color was digitally balanced according to the color transmittance capability of a high-resolution TV at the Jet Propulsion Laboratory (JPL), and is dependent on that device. In this color enhanced version of the panorama, detail in surface features are brought out via changes to saturation and intensity, holding the original hue constant. A threshold was applied to avoid changes to the sky".
