One of the most actively changing areas on Mars are the steep edges of the North Polar layered deposits.



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.

The image reveals relatively dark streaks down the steep slope, so landslide activity has already started in this area of Mars.
