The HRSC on board ESA's Mars Express will image the entire planet in full colour, 3D and with a resolution of about 10 metres. Selected areas will be imaged at 2-metre resolution. One of the camera's greatest strengths will be the unprecedented pointing accuracy achieved by combining images at the two different resolutions.
The Camera Head is the light grey unit in the middle and the top rectangular aperture. The Super Resolution Channel (SRC) is the black cylindrical aperture at lower right. The Camera Head and SRC together measure 515 x 300 x 260 mm. The Digital Unit is the black box at the back. The complete HRSC weighs 20.4 kilograms and consumes about 48.7 Watts with both camera and SRC working.
