Landslides in Coprates Chasma

Landslides in Coprates Chasma

This was submitted through HiWish by a class studying Mars: “What we targeted here shows evidence of mass wasting processes. We can see an obvious downslope of land due to gravity or even high pressure flows of water [in the past]. There could even be evidence of possible ancient lakes or rivers due to some of the surrounding upward slopes.”



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.

Circular Sand Dunes
Sand dunes of many shapes and sizes are common on Mars. In this example the dunes are almost perfectly circular, which is unusual.
