Mechanical Properties of Lunar Soil and Simulants
Investigation of the physical and mechanical properties of lunar soil carried out by the USSR and the USA; both in situ and on returned samples, has resulted in considerable information...
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...
Chemical Analysis in Space Exploration: A Lunar-based Chemical Analysis Laboratory (LBCAL)
Many questions need to be answered before humans can be supported for extended periods in space - an environment inimical to terrestrial life. While some questions of a physiological nature...
Assessing Lunar Resources with Remote Sensing
Four strategic architectures have been identified as part of the U.S. Space Exploration Initiative (SEI) to achieve U.S. goals with respect to the Moon. One of these architectures, space...
Recent Developments of the Carbotek Process for Production of Lunar Oxygen
Carbotek and Shimizu Corporation are conducting joint development work on the further development of the Carbotek Process to produce oxygen from lunar ilemnite by hydrogen reduction. The...
Hydrogen Reduction of Lunar Soil and Simulants
Carbotek, Inc., and the Energy and Environmental Research Center (EERC) are cooperating on further development of the Carbotek process to produce oxygen from lunar ilmenite by hydrogen...
Lunar Oxygen ? The Reduction of Glass by Hydrogen
The direct reduction of volcanic glass by hydrogen has been proposed as a method of extracting oxygen from the lunar soil. Experiments using lunar simulant glasses reacted with flowing...
A Modified Sulfate Process to Lunar Oxygen
A modified sulfate process which produces oxygen from iron oxide-bearing minerals in lunar soil is under development. Reaction rates of ilmenite in varying strength sulfuric acid have...
Steady State Composition with Low Fe?+ Concentrations for Efficient O2 Production by Magma Electrolysis of Lunar Soils
Parameters are estimated for a hypothetical, well stirred, continuous-feed electrolytic cell that converts 20% of a lunar soil feedstock to O2 gas,...
Production of Oxygen by Electro-Reduction of Lunar Ores
Anorthositic Lunar ores contain approximately 42 wt. pct. of oxygen. An electrolytic dissociation of the ore can provide a rich source of gaseous oxygen with silicon, aluminum, calcium,...
A Proposed Methodology for Ranking Space Resource Utilization Processes
A recent survey paper on lunar manufacturing identified 26 initial steps previously proposed as primary routes for lunar processing. Most of these have not been studied in sufficient detail...
Evaluation of Processing Options for Lunar Oxygen Production
Recent work on space resource utilization has lead to the identification of certain modifications of previously proposed processes which can be properly characterized as 'second generation'...
Materials and Structures Synergistic with In-Space Materials Utilization
The objective of this paper is to clearly demonstrate the significant advances made in recent months toward actual hardware realizations of various concepts for the utilization of in-space...
Mars Mission Designs: Comparing the Near Term Options
The benefits to be derived from manufacturing chemical rocket propellants from native resources on the Martlan surface are so great that it will almost certainly be a component of any...
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...
The Feasibility of Processes for the Production of Oxygen on the Moon
Twenty different processes for the production of oxygen on the Moon have been proposed. An evaluation of their perceived feasibility is presented. The lunar liquid oxygen (LLOX) production...
Power Sources for Lunar Bases
Working and living on the Moon requires artificial power sources both to operate equipment and to maintain life. This paper briefly surveys the power sources designed or proposed to support...
A Mars 1 Watt Vortex Wind Energy Machine
Ever since Viking I and II landed on the surface of Mars in the summer of 1976, man has yearned to go back. But before man sets foot upon the surface of Mars, unmanned missions such as...
Polycrystalline CdTe Solar Cells for Large-Scale Space Applications
Solar cells are recognized energy sources for use in space. In this talk, the current status of polycrystalline CdTe solar cell development and the potential use of this technology for...
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...
