MARS RECONNAISSANCE ORBITER HIRISE IMAGES
July 15, 2016

o Slope Instability
http://www.uahirise.org/ESP_037700_1710

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.

o Glorious Glacier
http://www.uahirise.org/ESP_045334_1350

This image has low-sun lighting that accentuates the many transverse
ridges on this slope, extending from Euripus Mons.

o Einstein and Mars
http://www.uahirise.org/ESP_045344_1420

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."

o Mesas and Pits
http://www.uahirise.org/ESP_045390_2215

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.

o Faulting Mars
http://www.uahirise.org/ESP_045497_1800

This region of Xanthe Terra has mostly been contracted due to thrust faulting.

o 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.

o Colorful Bedrock in the Central Uplift of an Impact Crater
http://www.uahirise.org/ESP_045519_1730

Large impact craters rebound from the initial shock, raising deep bedrock to
the surface in the central uplift of the crater.

o A Meandering Channel on Hellas

These gentle curves imply that a paleoriver carried lots of sediment along with
it, depositing it into Hellas about 4 billion years ago.

Information about the Mars Reconnaissance Orbiter is
online at http://www.nasa.gov/mro. The mission is
managed by NASA's Jet Propulsion Laboratory, a division
of the California Institute of Technology, for the NASA
Science Mission Directorate, Washington, D.C. Lockheed
Martin Space Systems, of Denver, is the prime contractor
and built the spacecraft. HiRISE is operated by the
University of Arizona. Ball Aerospace and Technologies
Corp., of Boulder, Colo., built the HiRISE instrument.
