HiPOD: Week of 10 November 2025

	A Dune Field of Mars The science goal of our observation is checking to see if (1) dune alcoves are forming and (2) if autumn or winter frost is forming that can help to investigate a connection between them. This is part of larger mid-latitude dune field activity study. This field is just south of the central peak we imaged in an earlier observation.
	Ridge Crossings The simplicity of this observation contrasts with the formation we see here: two parallel, curvilinear ridges (one crossing an impact crater) that have a similar shape to other examples attributed to carbon dioxided glaciers. Owing to how in-filled the crater is, the ridge likely formed long after the original impact.
	A Channel in Nereidum Montes The objective of this observation is to examine a channel. There are many channels in this region and this is one that is fairly typical. The channel makes a sharp turn in our image field. Pictures like this can help us understand how the climate has changed over time and the scene is also available in Context Camera data.
	The Channel in the Valley The objective of this observation is to examine a channel segment that is in the middle of a larger valley in northern Hellas Planitia. This relationship may mean that water flowed here twice in the past. The scene is also visible in Context Camera data.
	A Colorful Landslide in Eos Chasma Lower-resolution infrared data had previously revealed an unusual concentration of the igneous mineral orthopyroxene at this location.
