Self-portrait of Curiosity rover on Mars

Self-portrait of the Mars Curiosity rover on a flat, rocky perch in the Yellowknife Bay region of Mars’ Gale Crater.

This self-portrait of NASA’s Mars rover Curiosity combines 66 exposures during the 177th Martian day, or sol, of Curiosity’s work on Mars (Feb. 3, 2013). View larger.

Curiosity’s self-portrait provides a sweeping panoramic view of the rover’s location in February 2013, in the Yellowknife Bay region of Mars’ Gale Crater. Notice the distant sun in the sky of our solar system’s fourth planet. The rover’s flat, rocky perch is known as “John Klein.” It’s where Curiosity conducted its first rock-drilling activity last week.

The self-portrait was acquired to document the drilling site. Look carefully at the enlarged view of the Curiosity self-portrait, at the foot of the rover, and you’ll see a shallow drill test hole and a sample collection hole. They are 1.6 centimeters in diameter.

The rover’s Mars Hand Lens Imager (MAHLI) acquired this self-portrait. MAHLI is mounted on a turret at the end of the rover’s robotic arm, which is not visible in the mosaic. Wrist motions and turret rotations on the arm allowed MAHLI to acquire the mosaic’s component images.

Why can’t you see the robotic arm in the self-portrait? Remember, it’s a mosaic, combining 66 exposures. The arm was positioned out of the shot in most images, and the mosaic was assembled using portions of images not containing the robotic arm.
