HiRISE

The High Resolution Imaging Science Experiment camera is a camera on board the Mars Reconnaissance Orbiter. The 65 kg, $40 million (USD) instrument was built under the direction of the University of Arizona's Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp.. It consists of a 0.5 meter reflecting telescope, the largest of any deep space mission, which allows it to take pictures with resolutions up to 0.3 m, resolving objects about a meter across, or the size of a beachball.
