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.

Apollo lunar sounder experiment Apollo lunar sounder experiment

The scientific objectives of the Apollo lunar sounder experiment (ALSE) are (1) mapping of subsurface electrical conductivity structure to infer geological structure, (2) surface profiling to determine lunar topographic variations, (3) surface imaging, and (4) measuring galactic electromagnetic radiation in the lunar environment. The ALSE was a three-frequency, wide-band, coherent radar...

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).

Volcanic studies: Part B: Mare Serenitatis cinder cones and terrestrial analogs Volcanic studies: Part B: Mare Serenitatis cinder cones and terrestrial analogs

Small volcanic cones with summit craters or breached walls occur in several areas on the Moon. Most of these features have basal diameters of approximately 1 to 2 km and probably are not more than a few hundred meters in height. None have been so clearly photographed, however, as those shown in Apollo 17 metric and panoramic camera coverage of the southeastern margin of the Serenitatis...

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...
