Photogeology: Part F: reinterpretations of the northern Nectaris Basin
Don E. Wilhelms
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Geologic units of the Nectaris Basin rim have been interpreted as partly impact and partly volcanic in origin (refs. 29-4, 29-21, 29-35, 29-38, and 29-39). An exclusively volcanic origin was proposed for the material in the vicinity of the Apollo 16 landing site, slightly northwest of the Nectaris Basin (ref....

S.H. Zisk, Harold Masursky, D.J. Milton, G. G. Schaber, R.W. Shorthill, T.W. Thompson
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The purpose of the infrared (IR) and radar study of the Apollo data is to establish lunar surface conditions in the vicinity of the orbital tracks of the Apollo command modules during the J-series missions. Correlations and comparisons between the Earth-based radar observations, IR observations, and other data will be...
Photogeology: Part Y: physical and geological aspects of heiligenschein measurements
Robert L. Wildey
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Heiligenschein is the upsurge in reflected brightness as zero-phase angle is approached. For the first time, an effort has been made to investigate the diagnostic value of the heiligenschein photometric magnitude on a statistically significant scale. This investigation was performed by using the vertical photography of the Apollo 16 metric...
Photogeology: Part X: calibration of radar data from Apollo 16 results
S.H. Zisk, H. J. Moore
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Orbital and surface photography collected during the Apollo 16 mission can be used to calibrate existing Earth-based, high-resolution radar maps of the lunar surface. The absence of any theoretical treatment of the radar backscatter from irregular rocks has prevented the assignment of radar-echo cross sections to specific size distributions of...
Orbital-science investigation: Part H: sketch map of the region around the candidate Littrow Apollo landing sites
M. H. Carr
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
The photograph in figure 25-59 and the corresponding map (fig. 25-60) show the geology of part of the lunar surface just east of the Littrow rilles at the eastern edge of Mare Serenitatis. The most striking feature of the region is the extremely low albedo of the area mapped as...

Keith A. Howard, James W. Head
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
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...
Photogeology: Part J: ranger and other impact craters photographed by Apollo 16
H. J. Moore
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)

Orbital-science investigation: Part J: preliminary geologic map of the region around the candidate Proclus Apollo landing site
Don E. Wilhelms
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
The Proclus Crater region was mapped to test the value, for photogeologic mapping purposes, of Apollo 15 metric photographs and to estimate the scientific value of the area as a potential landing site. A metric photographic frame (fig. 25-67) serves as a base for a map of the region around...

Photogrammetry and altimetry: Part C: frequency distributions of lunar slopes
Sherman S.C. Wu, H. J. Moore
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The metric and panoramic cameras aboard the Apollo 16 spacecraft provided photographs on which photogrammetric techniques may be used to obtain precise measurements of horizontal distances and elevations. These measurements of horizontal distances and elevations. These measurements may in turn be used to obtain slope-frequency distributions of lunar surfaces at...
Photogeology: Part L: crater morphometry
Richard J. Pike
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
Morphometric analysis of lunar craters (ref. 29-75) complements the more traditional photointerpretive study of crater morphology. These two indirect approaches to the scientific investigation of lunar craters continue to be productive because the preferred alternative method, direct field examination of specific large craters, is not being undertaken in the current...
Orbital-science investigation: Part C: photogrammetry of Apollo 15 photography
Sherman S.C. Wu, Francis J. Schafer, Raymond Jordan, Gary M. Nakata, James L. Derick
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
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...

Baerbel K. Lucchitta
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
A panoramic camera frame (fig. 25-69) was used as the base for a geologic sketch map (fig. 25-70) of an area near Proclus Crater. The map was prepared to investigate the usefulness of the Apollo 15 panoramic camera photography in large-scale geologic mapping and to assess the geologic value of...

Wolfe, J.W. Young
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The Apollo 16 landing site in the lunar central highlands encompassed terra plains and adjacent mountainous areas of hilly and furrowed terra. These morphologic units, representing important terrane types in the lunar highlands, had been interpreted as volcanic on most premission geologic maps. However, it became apparent during the mission...
Photogeology: Part A: relative ages of some near-side and far-side terra plains based on Apollo 16 metric photography
Laurence A. Soderblom, Joseph M. Boyce
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
The materials of most light or terra plains predate the lunar maria and postdate the Imbrian event. In the vicinity of the Imbrium Basin, these materials have been called the Cayley Formation (ref. 29-3) but because of the subtle diversity of the terra plains over the near side, Whilhelms and...

Orbital-science investigation: Part O: regional variations in the magnitude of heiligenschein and causal connections
Robert L. Wildey
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
Approximately 35 reasonably good candidates for specialized photometric studies were found during a thorough examination of the frames exposed by the Apollo 15 metric camera. Of these, the majority was of value in heiligenschein studies (refs. 25-36 to 25-38). A few were of value for limited-interval delineation of the photometric...
Orbital-science investigation: Part G: lineaments that are artifacts of lighting
Keith A. Howard, Bradley R. Larsen
1972, Book chapter, Apollo 15 preliminary science report (NASA SP-289)
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...

Preliminary examination of lunar samples: Part A: a petrographic and chemical description of samples from the lunar highlands
The Lunar Sample Preliminary Examination Team
1972, Book chapter, Apollo 16 preliminary science report (NASA SP 315)
More than four-fifths of the surface of the Moon consists of a profoundly cratered irregular surface designated terra or highlands by analogy with the terrestrial continents. These terra regions have much higher albedos than the physiographically lower and much smoother mare regions. The difference in albedo can now be ascribed...
