Camera on NASA Mars probe snaps its 100,000th photo of the Red Planet

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. The image was snapped on Oct. 7, 2025. Over nearly 20 years, HiRISE has helped scientists understand how the Red Planet’s surface is constantly changing.

NASA's sharp-eyed Mars Reconnaissance Orbiter (MRO) just notched a big milestone.

MRO's HiRISE ("High Resolution Imaging Science Experiment") camera has now snapped 100,000 photos of the surface of Mars, NASA announced on Tuesday (Dec. 16).
