NASA Mars Reconnaissance Orbiter HiRISE Images – February 5, 2014

– Channels in Phlegra Montes http://hirise.lpl.arizona.edu/ESP_034228_2150

Also visible in a Context Camera image, pictures like this can help us understand the fluvial and climate history of ancient Mars.

– Fall Frost Accumulation on Russell Crater Dunes http://hirise.lpl.arizona.edu/ESP_034234_1255

Russell Crater dunes are a favorite target for HiRISE not only because of their incredible beauty, but for how we can measure the accumulation of frost year after year.

– A Spectacular New Impact Crater and Its Ejecta http://hirise.lpl.arizona.edu/ESP_034285_1835

This beautiful image shows a large, rayed blast zone around a 30-meter diameter crater, probably formed between 2010 and 2012.

– Squiggly Sand Dunes http://hirise.lpl.arizona.edu/ESP_034801_1300

It is now late Northern spring on Mars, so the Southern middle latitudes get very low-sun illumination that accentuates subtle topography.
