The Mars Reconnaissance Orbiter (MRO) will be launched on Aug. 10, 2005, carrying a payload of six science instruments and a communications relay package to boost the ongoing exploration of the red planet.
The largest science instrument on the spacecraft will be the University of Arizona's High Resolution Imaging Science Experiment (HiRISE), a 65 kilogram camera with a half-meter diameter primary mirror.
HiRISE will produce ultra-sharp photographs over 6 kilometer swaths of the martian landscape with a best imaging at 25 centimeters per pixel.
"Ball Aerospace has done a fantastic job building an instrument that meets our challenging performance requirements," McEwen said. "The HiRISE camera can collect the equivalent of about a thousand megapixel images in just three seconds."
