On 2 October 2025, MRO turned away from Mars to image 3I/ATLAS, only the third interstellar object ever observed passing through our solar system!

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.

It’s somewhat of a mystery why these features have flowed so much when they are so thin, the ice is so cold, and Martian gravity is so low.
