Linear Gully Activity in Russell Crater
HiRISE PICTURE OF THE DAY: 25 JUNE 2025
Linear Gully Activity in Russell Crater

We acquired this image to obtain more data points needed for a comparison of activity pre- and post a planet encircling dust event that occurred in 2018. We imaged Russell Crater many times before to track changes of gully activity that we see on the extensive dunes here. Russell Crater is located in Noachis Terra, with some of the oldest terrain on Mars.



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.
