Orbital-science investigation: Part B: photogrammetric analysis of Apollo 15 records Orbital-science investigation: Part B: photogrammetric analysis of Apollo 15 records
The three cameras—stellar, mapping, and panoramic—together with the laser altimeter, all included in the scientific instrument module (SIM) bay, represent an integrated photogrammatric system with extraordinary potential for extending knowledge of the lunar figure, surface configuration, and geological structure.

Orbital-science investigation: Part C: photogrammetry of Apollo 15 photography Orbital-science investigation: Part C: photogrammetry of Apollo 15 photography
Mapping of large areas of the Moon by photogrammetric methods was not seriously considered until the Apollo 15 mission. In this mission, a mapping camera system and a 61-cm optical-bar high-resolution panoramic camera, as well as a laser altimeter, were used. The mapping camera system comprises a 7.6-cm metric terrain camera and a 7.6-cm stellar camera mounted in a fixed angular...

Orbital-science investigation: Part F: regional geology of Hadley Rille Orbital-science investigation: Part F: regional geology of Hadley Rille
Study of the sinuous Hadley Rille (fig. 25-45) was a primary goal of the Apollo 15 mission. Local geology of the rille near the landing site is described in section 5 of this report. Preliminary study of orbital photography from Hasselblad, metric, and panoramic cameras makes possible a description of some regional relationships of the rille. Considerable use is also made of a...

Orbital-science investigation: Part G: lineaments that are artifacts of lighting Orbital-science investigation: Part G: lineaments that are artifacts of lighting
Many Apollo 15 orbital photographs, particularly those taken at low Sun-elevation angles, reveal grid patterns of lineaments. In some circumstances, the grid pattern is present in areas where structural control seems unlikely. For example, in an oblique view (fig. 25-52), the ejecta blankets of two fresh impact craters seem to have two intersecting sets of lineaments. Because previous...
