The Stereo Panorama Camera (PanCam) imaging experiment on-board the Mars Netlander Surface Modules is designed to obtain high-resolution multispectral stereoscopic panoramic images from each of the four Mars NetLander 2009 sites. The main scientific objectives to be addressed by the PanCam experiment are (1) to locate the landing sites, to and support the NetLander network sciences, (2) to geo-logically investigate and map the landing sites, (3) to study the properties of the atmosphere and of variable phenomena near the Martian surface, and (4) to provide an important contribution to the public and educational impact of the NetLander mission. The functionality of PanCam is similar to IMP (Imager for Pathfinder) which was used with the Mars Pathfinder mission, although the designs differ considerably by mass, size, and performance. With respect to Pathfinder, the Netlander PanCam will be lighter (about 1.7 kg including the data processing and camera control unit), and much more compact. Moreover, the field-of-view is significantly enlarged (53^o x 53^o), providing a better panoramic, and, in particular, stereoscopic coverage of the surface. The angular resolution will be 1.1 mrad per image pixel, i.e. structures of about 1 cm in dimension will be mapped to one pixel at a distance of 10 m. The camera will be mounted on a deployable and retractable boom which will raise the camera head to a height of about 0.7 m above the surounding terrain. Owing to the small radius of Mars, the horizon will be at a distance of about 2.2 km when the boom with the camera is fully deployed. The nearest features that can be accessed by the camera during operation (i.e. with the boom deployed) will be at a distance of about 0.8 m from the footprint of the PanCam boom. The camera head will be capable of being rotated by 360^o, thus providing coverage of the full panorama. Its stereo capability is achieved by taking images through two distinct wide-angle lenses separated by 110 mm, making distance measurements feasible up to approx. 50 m. A filter wheel containing six color filters (wavelength range 400...950 nm) provides the multispectral imaging capability.
