Truesense Imaging blog says that the four camera systems on Mars rover Curiosity are all based on the Truesense Imaging KAI-2020 image sensor. The Mars Descent Imager (MARDI) will capture images during descent to provide a framework of the landing site for early operations, while the Mars Hand Lens Imager (MAHLI) will capture high resolution images (up to 14.5 μm per pixel) of Martian rocks and soil after landing. And the Mast Camera (MastCam) includes two cameras – each with the same sensor but using different lenses – that will capture high resolution still and 720p video images of the planet’s surface. And all of them rely on the KAI-2020 to capture full color, high resolution images.
Curiosity is scheduled to land on Mars on August 6, 2012.
