Light-Toned Layered Material in Depression in West Juventae Chasma
HiRISE PICTURE OF THE DAY: 15 JULY 2025

Layered Material in Juventae Chasma

This image shows light-toned layered rock (sedimentary?) outcrops with spectacular erosional expressions that might (or not) give good clues on depositional setting. Were these sediments deposited here *after* Juventae Chasma opened up, or are they exhumed features, exposed by the opening and subsequent modification of the chasm? Can we tell?



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.
