HiPODs: Week of 14 June 2021

	A Martian Dust Avalanche Relatively dark slope streaks are common on steep dust-mantled slopes of Mars.
	Long-lasting Ice in a Young Crater At middle and high latitudes, new impact craters often dig up ice, which is initially bright and then fades away.
	Splat! Mars and the Earth run into debris in space regularly, and on our planet, meteors usually vaporize in the atmosphere. On Mars, not so much.
	Springtime on a Polar Cliff Every year there is a lot of slope activity in the springtime when sunlight warms these slopes.
	Changing Dust Boundary on Olympus Maculae Other maculae (unusually dark areas) are showing big pre/post 2018 dust storm changes in the size and crispness of their borders. Could this be an area of hyper-preferred dust devil activity? This particular macula could show significant changes with clues to the underlying mechanism. We’re about 1 Earth year later than the latest image for this region.
