HiRISE | New Captioned Images

15 July 2016

	Slope Instability One small section of this image shows boulders that have rolled down the slope of a crater wall, with the largest one approximately 6 meters across.
	Glorious Glacier This image has low-sun lighting that accentuates the many transverse ridges on this slope, extending from Euripus Mons.
	Einstein and Mars In February 1917, Albert Einstein wrote in a letter: "It is a pity that we do not live on Mars and just observe man's nasty antics by telescope."
	Mesas and Pits What's up and what's down? This image covers mesas, or high-standing plateaus, to the north and pits, or low-standing, depressions to the south.
	Faulting Mars This region of Xanthe Terra has mostly been contracted due to thrust faulting.
	North Polar Gypsum Dunes in Olympia Undae Unlike most of the sand dunes on Mars that are made of the volcanic rock basalt, these are made of a type of sulfate mineral called gypsum.
	Colorful Bedrock in the Central Uplift of an Impact Crater Large impact craters rebound from the initial shock, raising deep bedrock to the surface in the central uplift of the crater.
	A Meandering Channel on Hellas' Rim These gentle curves imply that a paleoriver carried lots of sediment along with it, depositing it into Hellas about 4 billion years ago.
