HiPOD: Week of 12 May 2025

	Cross-Section of a Complex Crater This image shows a cross-section of a complex crater in Terra Cimmeria, with plenty of interesting features to study.
	Impact-Induced Dust Avalanches These slope streaks are formed by dry dust avalanches and can take on incredible shapes.
	Ridges in Nilosyrtis Mensae The objective of this observation is to examine a series of ridges. There are many ridge networks in this region of Nilosyrtis Mensae, which has numerous channels and valleys carving through the terrain. This image shows a few ridges that seem to have just been exposed by erosion. Pictures like this could help us tell what time period the ridge networks were formed.
	Chaos Region near Osuga Valles The objective of this observation is to determine the nature of a small area of chaos terrain that has channels leading away from it. The image also includes a cross section of Osuga Valles, which is a complex set of channels located near Eos Chasma. The channels were likely cut by multiple episodes of flowing water.
	The Spurs in East Candor Chasma This site has been identified to be one of the best locales where triangular-faceted spurs are observed in Valles Marineris. Earlier observations of these formations used Viking images and a HiRISE picture can check this interpretation and refine it by quantifying fault displacement. This area may be key to interpreting the structural evolution of early east Candor Chasma.
