• One of NASA’s Key Cameras Orbiting Mars Takes 100,000th Image This view of a region called Syrtis Major is from the 100,000th image captured by NASA’s Mars Reconnaissance Orbiter using its HiRISE camera. • Over nearly 20 years, HiRISE has helped scientists understand how the Red Planet’s surface is constantly changing. • Credit: NASA/JPL-Caltech/University of ArizonaFull Image Details Mesas and dunes stand out in the view snapped by HiRISE, one of the imagers aboard the agency’s Mars Reconnaissance Orbiter. • After nearly 20 years at the Red Planet, NASA’s Mars Reconnaissance Orbiter (MRO) has snapped its 100,000th image of the surface with its HiRISE camera. • Short for High Resolution Imaging Science Experiment, HiRISE is the instrument the mission relies on for high-resolution images of features ranging from impact craters, sand dunes, and ice deposits to potential landing sites. • Those images, in turn, help improve our understanding of Mars and prepare for NASA’s future human missions there.

Article Summaries:

  • NASA’s Mars Reconnaissance Orbiter (MRO) has reached a milestone, with its HiRISE camera capturing its 100,000th high‑resolution image of the Martian surface. The photo, taken on Oct. 7, shows mesas and dunes in Syrtis Major, a region about 50 miles southeast of the Perseverance rover’s Jezero Crater. Scientists are using the image to study wind‑blown sand that forms dunes in the area. The target was suggested by a high‑school student through the HiWish public‑suggestion portal. HiRISE continues to provide detailed imagery that informs both scientific understanding and future human exploration plans.
