The Hills in Juventae Chasma

April 3, 2019
This image acquired on January 23, 2019 by NASA's Mars Reconnaissance Orbiter, shows some of the geologic diversity of Mars.
Context Image

This image captures some of the geologic diversity of Mars. There are hills of ancient terrains on the floor of Juventae Chasma, surrounded by younger sediments, including dark sand sheets and dunes that are likely active today.

The hills are heavily eroded by landslides, forming gullies in some places. Diverse colors represent unaltered volcanic minerals (blue and green) and altered minerals (brighter and reddish colors).

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 53.7 centimeters [21.1 inches] per pixel [with 2 x 2 binning]; objects on the order of 161 centimeters [63.4 inches] across are resolved.) North is up.

The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado.
