NASA Mars Reconnaissance Orbiter HiRISE Images: June 4, 2014

– An Alluvial Fan in a Low-Latitude Crater http://hirise.lpl.arizona.edu/ESP_028799_1565

On Mars, alluvial fans are sometimes visible in impact crater basins, as material from the steep rims is transported radially inward to the relatively flat floor.

– Touring a Dusty Region http://hirise.lpl.arizona.edu/ESP_034259_2040

As well as confirming a new impact, this image also showed other features commonly found in dusty areas: slope streaks and bed-forms.

– The Draa of Mars http://hirise.lpl.arizona.edu/ESP_034909_1755

Dune ripples are the smallest bed forms and can only be observed in high-resolution images acquired by HiRISE, and are commonly superposed on many surfaces.

– A Large Crater in Meridiani Planum http://hirise.lpl.arizona.edu/ESP_036397_1785

This crater is located in Meridiani Planum, about 20-kilometers northwest of where the Opportunity rover landed in 2004.
