PIA17028: In Focus: Caral Vallis

In Focus: Caral Vallis


This image shows the third of five broad channels on Mercury for which names were recently approved (see Caral Vallis ). The valleys are named according to the theme of "abandoned cities (and towns and settlements) of antiquity" that was developed especially for these landforms.

The vallis shown in this figure is named for Caral-Supe, a large settlement in the Barranca province of Peru that has been dated as one of the most ancient cities of the Americas, being inhabited from ca. 2627-1977 BCE. At its peak, Caral supported a population in excess of 3,000. This image is a portion of the MDIS global mosaic basemap MDIS global mosaic basemap that was acquired during MESSENGER's first year in orbit.

Background Info:

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
