Yellowknife Bay, Annotated

From a position in the shallow "Yellowknife Bay" depression, NASA's Mars rover Curiosity used its right Mast Camera (Mastcam) to take the telephoto images combined into this panorama of geological diversity.

A lip defining the edge of Yellowknife Bay is visible in the middle distance near the center of the image and in the farther distance on the right.

Shown in this panorama are the locations of the "Selwyn" section, the "John Klein" drill area, and the approximate distance between them. The Curiosity science team completed an extensive investigation of the chemical and textural properties of the rocks at these locations in advance of drilling at John Klein. This investigation included 25 analyses from the Alpha Particle X-ray Spectrometer (APXS), more than 1,000 images from the Mars Hand Lens Imager (MAHLI), and more than 12,000 laser shots from the Chemistry and Camera instrument (ChemCam).

The scene is a combination of three mosaics taken on Sols (Martian days) 137, 138, and 141 of Curiosity's work on Mars (December 24, 25 and 28, 2012). Each sol's images were acquired between about 8:30 and 9:30 a.m., local Mars solar time. Distances from the rover range from about 10 feet (3 meters) for the closest objects in the picture to about 100 feet (30 meters) for the most distant ones.

The mosaics have been white-balanced to show what the rocks would look like if they were on Earth. This image was originally released without labels on January 15, 2013, and can be found at PIA16701.
