Phyllosilicates West of Nili Fossae
HiRISE PICTURE OF THE DAY: 2 APRIL 2025

Clays West of Nili Fossae

Ah, Nili Fossae! The perennial runner-up for potential landing and exploration sites due to the presence of clays in this beautiful and rugged terrain. This observation features an area of mineralogical interest identified by the CRISM instrument, but lacks HiRISE coverage.



HiRISE Instrument News
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.

Icy Cliffs at the Martian North Pole
In the spring, we also sometimes see avalanches pouring down these cliff faces and this image was taken to search for more of them.
