The images for this view of the top of Curiosity's instrument-filled deck were taken through the left (wider-angle) eye of the Mastcam while the rover was being assembled at the Jet Propulsion Laboratory. The front of the rover is toward the right in this image. On the left is the outer cover for the mission's nuclear power source, a radioisotope thermoelectric generator. At far right is the turret a the end of Curiosity's robotic arm. The light-colored hexagonal object in the top left quadrant of the mosaic is the high-gain antenna, which is about 25 centimeters across.
