HiRISE PICTURE OF THE DAY: 17 NOVEMBER 2025

A Ridge North of Mamers Valles

Also visible in Context Camera data, the objective of this observation is to take a cloesr look at a ridge that extends diagonally scross the scene. In some spots, the surfaces on either side of this ridge seem different. This scene is north of Mamers Valles, a set of channels in a long, winding canyon.



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.

Glacial (Ice) or Lava Flow?
The geologic setting and latitude here suggest this is a glacial (ice-rich) flow, but the surface is broken into plates like many lava flows on Mars.
