Cratered and Rugged Geologic Units in Crater Floor Material
HiRISE PICTURE OF THE DAY: 3 JULY 2025

Cratered and Rugged

This observation shows crater floor material that is differentially eroded, with various units exhibiting divergent geomorphologies throughout the scene. One unit has a lobate form radiating inward from the crater wall: was it once a landslide deposit, now lithified, exhumed, and eroded?



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.

Complicated Lava Cooling
This HiRISE image shows a classic example of platy-ridged lava. Scientists think that this is the same as a lava type called “rubbly pahoehoe” on Earth.
