HiPOD: Week of 22 April 2024

	Hydrated Sulfates in Melas Chasma This image was acquired to get more information about a site where the CRISM instrument detected hydrated sulfates.
	Sediment Ponds in Tithonium Chasma This survey of the canyon floor of Tithonium Chasma in Valles Marineris reveals terrain of two distinct ages. The slopes and hilltops here are made up of rough rocky outcrop that was sculpted by impact craters of all sizes.
	Gullies in the Depths of Hellas Gullies are commonly found in the Martian mid-latitudes, particularly in the Southern Hemisphere. However, they are rare in the deepest parts of the Hellas impact basin.
	Defrosting Dunes This image shows a field a sand dunes in the springtime while the seasonal carbon dioxide frost is sublimating into the air.
	A Great Dark Spot This observation targets a pit partially filled with layered material and surrounded by banded terrain, as seen in Context Camera data.
