Remote sensing and photogrammetric studies: Part B: calibration of radar data from apollo 17 and other mission results Remote sensing and photogrammetric studies: Part B: calibration of radar data from apollo 17 and other mission results
A large quantity of data on backscattered polarized and depolarized radar echoes from the Moon has been collected from Earth at 3.8-cm wavelength (ref. 33-23). Depolarized echoes are particularly interesting because theory indicates that relatively strong depolarized echoes can be caused by the following factors.

Remote sensing and photogrammetric studies: Part C: comparison between photogrammetric and bistatic-radar slope-frequency distributions Remote sensing and photogrammetric studies: Part C: comparison between photogrammetric and bistatic-radar slope-frequency distributions
Stereoscopic photographs taken by the metric and panoramic cameras can be used to obtain information on the roughness and slope-frequency distributions of lunar surfaces (see appendix to this part). Bistatic radar on board Apollo 14, 15, and 16 spacecraft may also be used to obtain information on lunar surface roughness at two wavelengths—13 cm (S-band) and 116 cm (VHF).

Remote sensing and photogrammetric studies: Part D: repeatability of elevation measurements--Apollo photography Remote sensing and photogrammetric studies: Part D: repeatability of elevation measurements--Apollo photography
Stereoscopic photographs of the Moon taken by the metric and panoramic cameras on board the service module of Apollo spacecraft provide a source for quantitative data on lunar topography. The accuracy of the topographic data depends, in part, on the repeatability of elevation measurements. The repeatability depends on contrast in the stereoscopic image and is affected by many factors...

Stratigraphic studies: Part A: basalt stratigraphy of southern Mare Serenitatis Stratigraphic studies: Part A: basalt stratigraphy of southern Mare Serenitatis
Mare Serenitatis has long been noted for its conspicuous dark border (fig. 29-1). The Apollo 17 metric photographs traverse this border in southern Mare Serenitatis and show clearly superposition relationships among the mare and mare-related stratigraphic units. These photographs, together with full-Moon photographs, albedo measurements, and color information (table 29-I), provide the...

Stratigraphic studies: Part B: geologic setting of the dark mantling material in the Taurus-Littrow region of the Moon Stratigraphic studies: Part B: geologic setting of the dark mantling material in the Taurus-Littrow region of the Moon
A dark-colored surficial deposit covers lowlands and highlands along the southeastern margin of the Serenitatis basin. Sampling of this material was a major exploration objective of the Apollo 17 mission. Since completion of the mission, the dark mantle has been the subject of considerable controversy, inasmuch as no obvious stratified deposit was found in the landing area. Yet the...

Stratigraphic studies: Part C: relative ages of some near-side mare units based on Apollo 17 metric photographs Stratigraphic studies: Part C: relative ages of some near-side mare units based on Apollo 17 metric photographs
The lunar maria formed at different times and in multiple stages of extrusion. An understanding of their evolution is essential in placing the Apollo samples in a regional context and in interpreting the regional geology of a vast part of the lunar surface.

Stratigraphic studies: Part D: geologic map of the northern Crisium region Stratigraphic studies: Part D: geologic map of the northern Crisium region
Apollo 17 metric photographs (fig. 29-26) provide the best available coverage for geologic interpretation of northern Mare Crisium and the northern Crisium basin. The area was covered previously by low-resolution telescopic and Lunar Orbiter IV photographs and by oblique, high-illumination, or low-resolution photographs from earlier Apollo missions. One region in particular, between...

Surface electrical properties experiment Surface electrical properties experiment
The surface electrical properties (SEP) experiment was used to explore the subsurface material of the Apollo 17 landing site by means of electromagnetic radiation. The experiment was designed to detect electrical layering, discrete scattering bodies, and the possible presence of water. From the analysis of the data, it was expected that values of the electrical properties (dielectric...
