   Explanation: From July of 1997, a ramp from the Pathfinder lander, the
   Sojourner robot rover, airbags, a couch, Barnacle Bill and Yogi Rock
   appear together in this 3D stereo view of the surface of Mars. Barnacle
   Bill is the rock just left of the solar-paneled Sojourner. Yogi is the
   big friendly-looking boulder at top right. The "couch" is the angular
   rock shape visible near center on the horizon. Look at the image with
   red/blue glasses (or just hold a piece of clear red plastic over your
   left eye and blue or green over your right) to get the dramatic 3D
   perspective. The stereo view was recorded by the remarkable Imager for
   Mars Pathfinder (IMP) camera. The IMP had two optical paths for stereo
   imaging and ranging and was equipped with an array of color filters for
   spectral analysis. Operating as the first astronomical observatory on
   Mars, the IMP also recorded images of the Sun and Deimos, the smallest
   of Mars' two tiny moons. This July saw the launch of NASA's Mars
   Perseverance Rover on a mission to the Red Planet.
