   Explanation: [7]From July of 1997, a ramp from the Pathfinder lander,
   the Sojourner robot rover, airbags, a couch, Barnacle Bill and [8]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 [9]tiny moons. This July saw the
   launch of NASA's Mars Perseverance Rover on a [10]mission to the Red
   Planet.
