How successful were the lunar sampling tools: Implications for sampling Mars [PDF]

open access: yes
Like the Mars Sample Return endeavor, the Apollo lunar-sample program began with definition of strategy for sample collection and of scientific requirements for sampling hardware design. Several lessons can be illustrated by specific tools. The evolution

Formation of Nanophase Iron in Lunar Soil Simulant for Use in ISRU Studies [PDF]

open access: yes, 2005
For the prospective return of humans to the Moon and the extensive amount of premonitory studies necessary, large quantities of lunar soil simulants are required, for a myriad of purposes from construction/engineering purposes all the way to medical ...

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.

Nanophase Fe0 in lunar soils

open access: yesJournal of Earth System Science, 2005
Back scattered electron and transmission electron imaging of lunar soil grains reveal an abundance of submicrometer-sized pure Fe0 globules that occur in the rinds of many soil grains and in the submillimeter sized vesicular glass-cemented grains called agglutinates. Grain rinds are amorphous silicates that were deposited on grains exposed at the lunar

Magnetic Susceptibility Measurements for in Situ Characterization of Lunar Soil [PDF]

open access: yes
Magnetic separation is a viable method for concentration of components of lunar soils and rocks for use as feedstocks for manufacture of metals, oxygen, and for recovery of volatiles such as He-3.

Research on the Compactness of Lunar Soil Simulant Based on Static Cone Penetration Test

open access: yesApplied Sciences
The shear strength and bearing characteristics of lunar soil have a strong connection with its compactness. The compactness varies significantly with depth and has an important effect on engineering activities on the lunar surface.
