Ridges in Arabia Region
HiRISE PICTURE OF THE DAY: 30 JANUARY 2026

Ridges in Arabia

The objective of this observation is to determine the nature of narrow ridges. They may be from faults produced during old impacts. If so, recent research suggests they may be related to clay deposits, and they could be possible places to search for life.

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

Ejecta Moving into Crater in Chryse Planitia
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.
