HiRISE is a NASA project well worth following. Their photographs are consistently stunning.
Here are 3 recent beauts:
"A Wild Assortment of Jumbled Rocks"
"This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars."
"Mineral Veins"
"The bright linear features cutting the bedrock in the center region of this image look like mineral veins."
"Cratered Dune Forms"
"Known since at least 2003, this is a wonderful case of aeolian sandstone that preserves its original sand dune bedform shapes and lies unconformably over a previously-eroded surface of layered sedimentary rock."
