On Martian Soil
Discussions are ongoing about how and when to build human settlements on other worlds. Many scientific discussions have focused on settlements on Mars, and how the initial colonists would...
Remote Sensing of AstrofuelTM
A direct, high-resolution measurement from lunar orbit of the location of high concentrations of 3He in the lunar regolith is needed for the initiation...
The Challenge of Mining He-3 on the Lunar Surface: How All the Parts Fit Together
After the initial confirmation of the existence of He-3 on the lunar surface in 1985, there has been a flurry of activity both in the U.S. and abroad to find the best method of garnering...
Helium-3 on the Moon: Model Assumptions and Abundances
Solar-wind particles are present in the outer few 100 angstroms of each soil particle of the Moon. Of particular interest, are the volatiles hydrogen (40-100 ppm) and helium (5-45 ppm)....
In-situ Extraction of Lunar Soil Volatiles
Techniques for their recovery and utilization of the potentially valuable solar-wind elements embedded in the lunar regolith have been proposed. In order to acquire quantities of 3He...
A Simple Method of Producing Lunar Soil Simulants for Engineering Studies
This paper suggests that it is possible to obtain large quantities of simulated lunar regolith that can be used for feasibility studies of lunar base construction and excavation machinery...
Construction of Large Lunar Structures by Fusion Welding of Sintered Regolith
Regardless of material used, construction of large lunar structures using indigenous resources is likely to requires joining of simple blocks or pieces. Fusion welding using an optical...
Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...
Design Criteria for Lunar Construction Equipment
It is anticipated that lunar installations will, from the beginning, require moving and assembly of components and the use of lunar regolith as a construction material. The functional...
Analysis of Glass-Ceramic Production from Lunar Resources
Two simulated regoliths were used to investigate the effects of processing and composition on the properties of lunar-derived glass-ceramics. For the simulant with moderate iron concentration,...
Inflatable Structures of Non-Circular Cross Section
This paper discusses six approaches to achieve an inflatable structure of non-circular cross section for use in lunar base development. Other papers have examined potential multiple uses...
Experimental, Physical and Numerical Modeling of Lunar Regolith and Lunar Regolith Structures
An extensive series of laboratory strength and deformation experiments have been performed on a lunar regloith simulant. Results of these experiments are compared to results from experiments...
Constructing Radiation Shields with Textiles for Lunar Applications
The problem of radiation shielding on the lunar surface is significant. The mass required for adequate shielding is enormous and economics would dictate the use of lunar soil for this...
In-situ Release of Solar Wind Gases from Lunar Soil
A concept is described which has the potential to perform the in-situ heating of the lunar regolith in order to release the solar wind gases. The poor thermal conductivity of the lunar...
Isotopic Separation of ?He/4He From Solar Wind Gases Evolved from the Lunar Regolith
The potential benefits of 3He when utilized in a nuclear fusion reactor to provide clean, safe electricity in the 21st century for the world's inhabitants...
Sulfur as a Lunar Resource
Sulfur on the Moon may prove to be a satisfactory replacement in some uses for lighter volatile elements and their compounds. Although sulfur is not richly concentrated on the Moon, it...
Lunar Liquid Oxygen Production Facilities
Production of oxygen beyond Earth's gravity well has been shown to be an economic asset for interplanetary travel using chemical combustion propulsion. Requirements for lunar liquid oxygen...
INTERLUNE Concept for Helium-3 Fusion Development
Many considerations suggest that in the 21st Century, deuterium/helium-3 (D-3He) fusion will be the electricity generation system of choice to replace...
Beneficiation of Lunar Rocks and Regolith: Concepts and Difficulties
Considerations of the resources which can provide feedstocks of ilmenite, glass, agglutinates, anorthite, etc. at a lunar base require an appreciation of the geology of the situation....
Lunar He-3 Mining: Improvements on the Design of the UW Mark II Lunar Miner
One of the minor consituents of the solar wind which has been implanted in the lunar regolith over its several billion year history, is helium 3 (He-3), a rare isotope of helium which...
