Mars Express orbiter instruments  High Resolution Stereo Camera (HRSC)  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.

Information on the interior will be gleaned from the planet’s gravity field, which will be calculated from changes in the velocity of the spacecraft relative to Earth. Surface roughness will be deduced from the way in which the radio waves are reflected from the martian surface. "Variations in the gravitational field of Mars will cause slight changes in the speed of the spacecraft relative to the ground station, which can be measured with an accuracy of less than one tenth the speed of a snail at full pace," says Martin Pätzold, MaRS PI from Köln University, Germany.
