LUNAR ORBITER IV
CRATER SCHICKARD AND ENVIRONS, INCLUDING CRATERS PHOCYCLIDES, NASMYTH, WARGENTIN, LACROIX, AND BYRGIUS, TAKEN BETWEEN 11-26 MAY, 1967.
Vintage NASA Langley Research Center telephoto panorama, made up of three silver gelatin contact prints, each approx 17 x 21 1/4 inches, of Lunar Orbiter images IV-167H 1-3.
A spectacularly detailed view of the southwest sector of the moon, near the lunar limb, covered in impact craters and lava flooded plateaus.
Lunar Orbiter IV flew in high altitude polar orbits with the primary objective of mapping the near side of the Moon in high resolution, with 100% of the nearside being photographed, and 95% of the farside. A 40 by 45 foot mosaic was created at NASA's Langley Research Center using the images taken by the Lunar Orbiter IV, and visitors were allowed to stand or crawl over it. The mosaic was used to determine the sites to be photographed in higher resolution by the Lunar Orbiter V.
