Lunar and Hawaiian Physical Features Compared

Physical Properties of the Lunar Surface

This chapter discusses the physical properties of the lunar surface, determined at depths varying from a few micrometers to a few tens of meters. The properties considered include geotechnical properties (those properties of a planetary surface needed to evaluate engineering problems, including the mechanical properties of soil and rock), electrical and electromagnetic properties, and the refle...

Apollo 14 Visibility Tests: Visibility of Lunar Surface Features and Lunar Landing

Cosmic and Geologic Import of the Lunar Features.

Flux of micrometeoroids: lunar sample analyses compared with flux model.

From an analysis of trace element abundances in lunar soils, the influx of meteoritic mass into the lunar surface has recently been estimated by Keays et al. (1) as 3.8 X 10-9 gcm-2 yr-1 and later by Ganapathy et al. (2) as 4 X 10-9 g cm-2 yr-1. I shall show in this note that these numbers are in agreement with independent estimates of the mass distribution for cometary meteoroids. Using the re...

Lunar cryptomaria: Physical characteristics, distribution, and implications for ancient volcanism

Cryptomaria, lunar volcanic deposits obscured by crater and basin impact ejecta, can provide important information about the thermal and volcanic history of the Moon. The timing of cryptomare deposition has implications for the duration and flux of mare basalt volcanism. In addition, knowing the distribution of cryptomaria can provide information about mantle convection and lunar magma ocean so...
