The lunar craters Tycho, Copernicus, and Aristarchus have been observed during lunar night at wavelengths between 3 and 14 microns. After an initial fast decrease to a color temperature of 220�K, the temperature remains nearly constant through the lunar night. The data suggest that these thermal anomalies (craters) contain hot and cold regions with the hot portions constituting 2 to 10 percent of the area and probably thermally connected to a subsurface temperatuer of about 200�K. 

Infrared studies of the lunar terrain

Observations have been made of the unlit limb of the Moon at infrared wavelengths, and detailed apparent temperature charts for the entire limb are presented. A number of thermal anomalies lying

Lunar rocks and thermal anomalies

Recent microwave and infrared spectral observations of several of the large bright-rayed craters on the moon suggest that the thermal anomalies in these craters are produced by large rocks, boulders,

Infrared observations of the moon and their interpretation

The lunar spectrum, resulting from both the directly scattered solar radiation and the Moon's intrinsic thermal radiation, is described. The variations of the thermal component with latitude and

Thermophysics of the planet Mercury

Recent observations of the thermal emission of Mercury at microwave and infrared frequencies now permit a determination of the thermal and electrical properties of the subsurface of the planet. Radar

Infrared Moon: A Review

T brightness temperature of the lunar surface has been determined using telescopes on Earth, on balloons, and on aircraft. Observations revealed more than a thousand anomalous regions (hot spots)

Specific Heats of Lunar Surface Materials from 90 to 350 Degrees Kelvin

The specific heats of lunar samples 10057 and 10084 returned by the Apollo 11 mission have been measured by use of an adiabatic calorimeter, finding that the thermal parameter γ=(kpC-� for the lunar surface will accordingly vary by a factor of about 2 between lunar noon and midnight.

The Lunar and Planetary research program led by Dr John (Jack) Salisbury in the 1960s at the United States Air Force Cambridge Research Laboratories (AFCRL) investigated the surface characteristics

Radar Maps of the Moon at 70‐cm Wavelength and Their Interpretation

Polarized and depolarized radar maps of the moon have been obtained at the Arecibo Ionospheric Observatory at a wavelength of 70 cm. These maps show strong positive anomalies, many of which are

The lunar surface layer

This article describes the application of the concepts and laws of physics to the study of the formation, structure and properties of the surface layers of the moon. Both impact and internal

Lunar orbital science

SummaryOrbital science has, to the present, concentrated on studies of force fields, particles, and visible photography. Cameras have been the major scientific instrument (it could be debated that
