Lunar Volatiles and Mineralogy Mapper (LVMM) payload for the lunar Volatile and Mineralogy Mapping Orbiter (VMMO)

CubeSats and SmallSats for Remote Sensing VI, 2022
The Lunar Volatile and Mineralogy Mapping Orbiter (VMMO) comprises a low-cost 12U Cubesat with deployable solar arrays, X-Band/UHF communications, option of electric or chemical propulsion, the Lunar Volatiles and Mineralogy Mapper (LVMM) payload, and an optional GPS receiver technology demonstrator. The LVMM facilitates three operational modes: Active

Lunar Subsurface Mineralogy and Density Profile Modelling based on Moon Mineralogy Mapper Observation

Acta Geologica Sinica, 2021
AbstractThe methods of deriving FeO and TiO2contents from the Clementine spacecraft data were discussed, and an approach was developed to derive the content from the measurements using the Moon Mineralogy Mapper (M3) instrument on Chandrayaan‐1. The density of lunar bedrock was then modeled on the basis of the derived FeO and TiO2abundances.

Mineralogy, petrology, and geochemistry of the lunar samples

Reviews of Geophysics, 1975
The years 1971–1974 mark the maturing of lunar mineralogy, petrology, and geochemistry into a full‐fledged science. During these years the prime objective of lunar sample investigation teams changed from general surveys of the nature of returned lunar material into problem‐oriented studies. Four general areas of interest that evolved during these years

Mineralogy and Petrography of Lunar Samples

Science, 1970
The lunar samples consist largely of augite, calcic plagioclase, and ilmenite. Olivine is a minor constituent of some rocks, as is cristobalite. Other minerals present in small amounts include tridymite, chromite, kamacite, taenite, and troilite. The principal rock types can be broadly grouped into ilmenite basalts and breccias.

Mineralogy and Petrology of Some Lunar Samples

Science, 1970
Chemical analyses and norms of four samples are presented which confirm original estimates of low silica, unusual abundance of titania, and low oxidation state of the rocks. Accounts are given of mineralogy and petrology of fine- and coarse-grained igneous rocks and microbreccias with emphasis on chemical composition of individual minerals and glasses.

Mineralogical and Petrological Investigations of Lunar Samples

Science, 1970
Fragments of igneous rocks and breccias, and one coarse-grained rock with thin sections, have been studied. Minerals found include pyroxene, plagioclase, olivine, ilmenite, troilite, ulvöspinel, native iron, cristobalite, tridymite, alkali feldspar, apatite, and quartz. Textures are described and interpreted.
