HiRISE (High Resolution Imaging Science Experiment) observations are a key component of the Mars Reconnaissance Orbiter mission, which aims to study the geology and climate of Mars using high-resolution imaging. HiRISE captures detailed images of the Martian surface, allowing scientists to study features such as craters, dunes, and gullies in great detail. These observations help to improve our understanding of Mars' geological history, climate patterns, and potential for past or present habitability. The data collected by HiRISE has been instrumental in identifying potential landing sites for future Mars missions and informing ongoing research on the red planet.
