HiPOD: Week of 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.
	The Shifting Winds of Hellas Plantia Sand dunes on Mars are subject to variety of wind regimes and impacting conditions that have produced a diverse catalog of dune shapes and sizes.
	Boulder Patterns Some of these patterns resemble the polygons often seen at high latitudes on Mars, which form from seasonal expansion and contraction of ground ice.
	HiRISE Image of Exocomet 3I/ATLAS On 2 October 2025, MRO turned away from Mars to image 3I/ATLAS, only the third interstellar object ever observed passing through our solar system!
	Landforms in Noachis Terra This target request originated from our public suggestion tool HiWish: “There are some elevations in the middle of what seems to be plain ground. Should be of interest to find out how it formed.” Noachis Terra is one of the most extensive land masses on Mars, lying in the Southern Highlands and west of the Hellas impact basin.
