Frost and sand are common occurrences on Mars. The bright carbon dioxide frost condenses out of the atmosphere during winter, marking a stark contrast with the dark sand dunes found here.



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.
