Exploring Mars with HiRISE

Alfred McEwen

The High Resolution Imaging Science Experiment (HiRISE) on Mars Reconnaissance Orbiter (MRO) has acquired more than 10,000 images of Mars with 8.6 Terapixels of data, covering ~0.7% of the surface. Images are normally 5-6 km wide with partial 3-color coverage, and their scales typically range from 25-60 cm/pixel. More than 1,000 stereo pairs have been acquired and 50 digital terrain models (DTMs) completed; these data have led to some of the most significant science results. New methods to measure and correct distortions due to pointing jitter facilitate topographic and change-detection studies at sub-meter scales. There are recent results concerning a wide range of surface features and processes, but I will emphasize a few favorite topics such as Noachian megabreccia and the current impacts.
