Channels North of Hellas Region
HiRISE PICTURE OF THE DAY: 3 APRIL 2025

Channels North of the Hellas Region

The objective of this observation is to examine small, curved channels that are meeting in this spot. Perhaps these channels are the result of hot ejecta landing on ice-rich ground. This scene, along with large craters, is also visible in Context Camera data.



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.
