New Images Used to Pick Mars Lander Site

The combination of images, taken by the High Resolution Imaging Science Experiment, through different color filters (10 red filter detectors, two in blue-green, and 10 for infrared wavelengths) is providing a new view of Mars. The images are taken on NASA's Mars Reconnaissance Orbiter and will ideally help scientists determine the landing site for a future Martian explorer that is set to land in 2010. The images were created in false colors to maximize color differences, so the landscapes they depict would look different to a human standing on Mars.
Color also helps geologists match layers in the Martian terrain. "Color data are proving very useful in interpreting geologic processes and history on Mars," McEwen said. "The images we're releasing today include views of some of the most exciting and compositionally diverse areas on the planet. They are really interesting."
