Crater on Wrinkle Ridge
HiRISE PICTURE OF THE DAY: 29 NOVEMBER 2023

Crater on a Wrinkle Ridge

This observation can inform us about the impact cratering process here along this wrinkle ridge, as well as see if there are any flow ejecta on the side of the crater wall. We can also take a look at the topography of the wrinkle ridge and its direction and shape.



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.
