</p><p>The Mars Hand Lens Imager (MAHLI) on the arm of NASA's Mars rover Curiosity took this image of a rock called "Et-Then" during the mission's 82nd sol, or Martian day (Oct. 29, 2012.) 
</p><p>The rock's informal name comes from the name of an island in Great Slave Lake, Northwest Territories, Canada. 
</p><p>MAHLI viewed the rock from a distance of about 15.8 inches (40 centimeters). The image covers an area about 9.5 inches by 7 inches (24 centimeters by 18 centimeters). Et-Then is located near the rover's front left wheel, where the rover has been stationed while scooping soil at the site called "Rocknest."
</p><p>This is one of three images acquired by MAHLI from slightly different positions so that a three-dimensional information could be used to plan possible future examination of the rock.
