   Explanation: [7]Put on your red/blue glasses and gaze across the
   western [8]Ocean of Storms on the surface of the Moon. The 3D view
   features Apollo 12 astronaut Pete Conrad [9]visiting the Surveyor 3
   spacecraft 50 years ago in November of 1969. [10]Surveyor 3 had landed
   at the site on the inside slope of a small crater about 2 1/2 years
   earlier in April of 1967. Visible on the horizon beyond the far crater
   wall, Apollo 12's [11]Lunar Module Intrepid touched down less than 200
   meters (650 feet) away, easy moonwalking distance from the robotic
   Surveyor spacecraft. The stereo image was carefully created from two
   separate pictures [12](AS12-48-7133, AS12-48-7134) taken on the
   [13]lunar surface. [14]They depict the scene from only slightly
   different viewpoints, approximating the separation between human eyes.
