NASA's Curiosity rover has seven cameras mounted on its mast, including the two-camera, full-color Mastcam system; the four-camera, black-and-white Navcam system; and ChemCam, which monitors the effects of the rover's laser blasts. The Mars Hand Lens Imager is one of the instruments on the rover's robotic arm, the Mars Descent Imager is mounted on the robot's belly, and the eight-camera Hazcam system rounds out Curiosity's array of 17 cameras.
