The Surface Chemical Composition of Lunar Samples and Its Significance for Optical Properties [PDF]

open access: yes
The surface iron, titanium, calcium, and silicon concentration in numerous lunar soil and rock samples was determined by Auger electron spectroscopy. All soil samples show a large increase in the iron to oxygen ratio compared with samples of pulverized ...

An Astronaut's Risk of Experiencing a Critical Impact from Lunar Ejecta During Lunar EVA [PDF]

open access: yes
The Moon is under constant bombardment by meteoroids. When the meteoroid is large, the impact craters the surface, launching crater ejecta far from the impact potentially threatening astronauts on the lunar surface.

Resource availability at Taurus-Littrow [PDF]

open access: yes
Early lunar technologies will probably use a common lunar material as ore. They will be robust to minor fluctuations in feedstock composition and will not require appreciable feedstock beneficiation such as rock grinding or mineral concentration ...

Enabling lunar and space missions by laser power transmission [PDF]

open access: yes
Applications are proposed for laser power transmission on the Moon. A solar-pumped laser in lunar orbit would beam power to the lunar surface for conversion into either electricity or propulsion needs.
