Orbital photo of lunar surface.<br>This photo was used in Figure 25-89 (c) of the <i>Apollo 15 Preliminary Science Report</i> (SP-289, 1971), which has the following caption:<br>Mare Vaporum area. (a) Map of area, with arrow indicating Apollo 15 landing site approximately 200 km north. (b) Lunar Orbiter IV photograph of 200- by 120-km area shown in part (e) of this figure. (c) Near-terminator photograph of central and western Mare Vaporum. Features made visible or enhanced in this low-Sun-angle view include a 25-km-diameter mare dome (upper arrow) and numerous mare ridges of varying widths and orientations (lower arrow). Many structures such as flow fronts, elongate craters, and depressions are visible in the near terminator photography, which provides additional data regarding the surface and subsurface evolution of the maria (AS15-98-13302).
