Geophysical Methods: an Overview [PDF]

Geophysics is expected to have a major role in lunar resource assessment when manned systems return to the Moon. Geophysical measurements made from a lunar rover will contribute to a number of key studies: estimating regolith thickness, detection of ...

Lunar elemental composition and ivestigations with D-CIXS x-ray mapping spectrometer on SMART-1 [PDF]

, 2004
The D-CIXS Compact X-ray Spectrometer on ESA SMART-1 successfully launched in Sept 2003 can derive 45 km resolution images of the Moon with a spectral resolution of 185 eV, providing the first high-resolution global map of rock forming element ...

Surface chemistry of selected lunar regions [PDF]

A completely new analysis has been carried out on the data from the Apollo 15 and 16 gamma ray spectrometer experiments. The components of the continuum background have been estimated. The elements Th, K, Fe and Mg give useful results; results for Ti are

Selecting a Superior Landing Area in the Region Far From Procellarum KREEP Terrane

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The area far from the Procellarum KREEP Terrane (PKT) is important for future landing exploration. Mare Crisium, located in the area, has been identified as an essential landing option for the Lunar Geophysical Network (LGN) mission.

Geologia de la Lluna [PDF]

Ja des d’antic es coneix que la Lluna està formada per dos tipus de terrenys que tradicionalment s’han anomenat maria i terrae. Les mostres recollides per les missions Apol·lo, Luna i els meteorits d’origen lunar trobats a la Terra ens han permès ...
