The optical properties of lunar softs are different than those of rocks from which they are derived. As a consequence of lunar space weathering, soils are darker and exhibit a distinctive red-sloped continuum and weaker mineral absorption bands. The accumulation of dark glass-welded aggregates (agglutinates) has been thought to account for these optical effects of space weathering on lunar soils. Spectroscopic analyses of agglutinate separates and size fractions for a suite of lunar softs…

The optical properties of the finest fraction of lunar soil: Implications for space weathering

Abstract— The fine fraction of lunar soils (<45 μm) dominates the optical properties of the bulk soil. Definite trends can be seen in optical properties of size separates with decreasing particle

Detecting Sub‐Micron Space Weathering Effects in Lunar Grains With Synchrotron Infrared Nanospectroscopy

Space weathering processes induce changes to the physical, chemical, and optical properties of space‐exposed soil grains. For the Moon, space weathering causes reddening, darkening, and diminished

Space weathering from Mercury to the asteroid belt

The variety of evidence bearing on the nature of space weathering is reviewed. The effects of space weathering include spectral darkening, reddening and subdued absorption bands, and the distinctive

Mineralogical and chemical characterization of lunar highland soils: Insights into the space weathering of soils on airless bodies

[1] With reflectance spectroscopy, one is measuring only properties of the fine-grained regolith most affected by space weathering. The Lunar Soil Characterization Consortium has undertaken the task


Abstract We have measured the infrared (2.08–14 μm) directional hemispherical reflectance spectra of lunar soils representing the major lithologic units so far sampled on the lunar surface, and soils

A Model of Spectral Albedo of Particulate Surfaces: Implications for Optical Properties of the Moon

A simple one-dimensional geometrical-optics model for spectral albedo of powdered surfaces, in particular of lunar regolith, is presented. As distinct from, e.g., the Kubelka–Munk formula, which



Lunar Spectral Reflectivity (0.30 to 2.50 Microns) and Implications for Remote Mineralogical Analysis

The spectral reflectivity of several lunar areas was measured with ground-based telescopes and a narrow absorption band centered at 0.95 micron was revealed for the first time, suggesting there are no major differences in the mineralogy at those sites studied.

Moon: near-infrared spectral reflectance, a first good look.

A positive identification of the minerals olivine, plagioclase, and several types of pyroxenes were made at several locations on the lunar surface by using remote measurements. For example, the

The relationship of the lunar regolith less than 10-microns fraction and agglutinates. II - Chemical composition of agglutinate glass as a test of the 'fusion of the finest fraction' /F3/ model

Agglutinate glasses from nine Apollo soils have been studied using an automated electron microprobe technique in order to test the fusion of the finest fraction model proposed by Papike (1981). The

Effects of vapor-phase deposition processes on the optical, chemical, and magnetic properties OE the lunar regolith

The processes of solar wind sputtering and meteoritic impact vaporization have created materials in the lunar regolith which were deposited from a vapor phase. Although the quantity of such exotic

The spectral reflectance properties (0.3–1.1 μ) of a number of lunar mare, upland, and bright crater areas were observed with the use of ground-based telescopes. These new data are discussed in view

The lunar regolith: Chemistry, mineralogy, and petrology

The lunar regolith, a several meter thick layer of unconsolidated debris, forms the interface between the moon and its space environment. The regolith forms from lithic sources by the destructional

Alteration of Lunar Optical Properties: Age and Composition Effects

Evidence from Apollo 11 and Apollo 12 samples and telescopic spectral reflectivity measurements indicates that the maria are similar in mineralogy on a regional scale and that the highlands are consistent with an anorthositic-gabbro composition.

Spectral reflectance characteristics of the meteorite classes

Spectral reflectance curves (0.35–2.5 μm) have been measured for about 150 individual meteorite specimens which represent nearly all the types and subtypes of meteorites present in terrestrial

Crystallized spheres of orange glass from Shorty Crater at the Apollo 17 site are shown by spectral reflectance data to be the characteristic ingredient of the dark mantling deposit of the
