100,000 Images of Mars

On 7 October 2025, the HiRiSE camera aboard MRO acquired this image of the Syrtis Major plains, about 85 kilometers from NASA’s Perseverance rover in Jezero Crater. This marks over 100,000 HiRISE images of Mars, which is a fabulous milestone.

Since July 23, 2023, HiRISE observations have lacked data from the RED4 CCD due to a hardware issue, creating a gap in the middle of image products and reducing the color swath to 1 CCD width. We are investigating the hardware issue and may be able to acquire some RED4 data in the future.
