The region on the north side of Terby Crater contains layered bedrock including bright materials thought to be sediments, perhaps deposited by flowing water.
On 7 October 2025, the HiRISE camera aboard MRO acquired an image of the Syrtis Major plains that marks over 100,000 images of Mars, which is a fabulous milestone!
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 mid-2023, our RED4 CCD has operated only intermittently due to a hardware issue,
creating gaps in the middle of some image products and reducing the color swath to 1 CCD width.
We continue to command RED4 in all observations and it returns data approximately 50% of the time
The objective of this observation is to examine what appears to be ejecta moving into a small crater. More resolution is needed to tell exactly what is going on here. This scene is also visible in Context Camera data. Chryse Planitia is a region where the Viking 1 lander and Mars Pathfinder touched down.
