Title:
Steep Cliffs on Mars
Explanation:
Vertical cliffs of nearly two kilometers occur near the North Pole of Mars. Also visible in the above image [ http://www.esa.int/…] of the Martian North Polar Cap [ http://antwrp.gsfc.…] are red areas of rock and sand, white areas of ice, and dark areas of unknown composition but hypothesized to be volcanic ash [ http://volcanoes.us…]. The cliffs are thought to border volcanic caldera [ http://antwrp.gsfc.…]. Although the sheer drop [ http://antwrp.gsfc.…] of the Martian cliffs is extreme, the drop is not as deep as other areas in our Solar System [ http://www.nineplan…], including the 3.4-kilometer depth of Colca Canyon [ http://www.bootsnal…] on Earth and the 20 kilometer depth of Verona Rupes [ http://en.wikipedia…] on Uranus' moon Miranda [ http://astrogeology…]. The above image [ http://www.esa.int/…], digitally reconstructed into a perspective view [ http://adsabs.harva…], was taken by the High Resolution Stereo Camera [ http://berlinadmin.…] on board the ESA [ http://www.esa.int/]'s robotic Mars Express spacecraft [ http://www.esa.int/…] currently orbiting Mars [ http://www.nineplan…].
