View toward 'Vera Rubin Ridge' on Mount Sharp, Mars.
This look ahead from NASA's Curiosity Mars rover includes four geological layers to be examined by the mission,
and higher reaches of Mount Sharp beyond the planned study area. The redder rocks of the foreground are
part of the Murray formation. Pale gray rocks in the middle distance of the right half of the image are in the
Clay Unit. A band between those terrains is “Vera Rubin Ridge.” Rounded brown knobs beyond the Clay Unit
are in the Sulfate Unit, beyond which lie higher portions of the mountain.
The view combines six images taken with the rover's Mast Camera (Mastcam) on Jan. 24, 2017, during the 1,589
th
Martian day, or sol, of Curiosity's work on Mars, when the rover was still more than half a mile (about a kilometer)
north of Vera Rubin Ridge. The panorama has been white-balanced so that the colors of the rock and sand ma-
terials resemble how they would appear under daytime lighting conditions on Earth. It spans from east-southeast
on the left to south on the right. The ridge was informally named in early 2017 in memory of Vera Cooper Rubin
(1928-2016), whose astronomical observations provided evidence for the existence of the universe's dark matter.
