HiPOD: Week of 26 May 2025

	Strange Mesas in Noachis Terra This image shows several mesa-like features in the Noachis Terra region of Mars. The saucer-like shape of these features is unusual and begs the question of how they formed.
	A Landslide by (Possible) Impact in Iani Chaos Iani Chaos is a heavily fractured region that contains a multitude of hummocks or flat-topped mesas thought to be the source of catastrophic floods that formed Ares Valles.
	In Search Of...Extraterrestrial Glaciers Glacial flow on Mars is likely to be much slower, so cold ice is much more viscous than the warmer ice we have on the Earth and so flows slower. Are they flowing today?
	Cyclic Bedding in Firsoff Crater The rock layers are thought to be evidence of cyclic deposition, caused by changes in the orbit of Mars. The changes in the climate are imprinted into the rock record as different layers.
	A Channel and Crater near Millochau Crater The objective of this observation is to examine a channel that connects to a crater. A closed crater lake may have existed in this spot. This scene is located in the highlands of Tyrrhena Terra and is also visible in Context Camera data.
