Floor-Fractured Crater in Elysium Planitia
HiRISE PICTURE OF THE DAY: 4 APRIL 2025

A Floor-Fractured Crater

This formation looks vaguely tumulus-like, like an early stage of a process that might be the result from lava invasion that elsewhere leaves only a couple of rafted blocks. This scene is located in Elysium Planitia.



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.

Ridges in Lycus Sulci
Much of the rocks in this area have been subjected to erosion by the wind, so the surface we see today was originally buried deep underground.
