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,...
Production of Lunar Oxygen, Iron, Magnesium, and Silicon by Aqueous Hydrofluoric Acid Leaching
Aqueous hydrofluoric acid (HF) processing of lunar regolith offers the versatile options of lunar iron and oxygen production by room temperature electrolysis as well as the extraction...

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...
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...
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...
On-Orbit Chipless Cutting and Tube Welding in Space Station Freedom
Micro-gravity and strict environmental constraints of the laboratory, Habitation and other manned structures which comprise Space Station Freedom demand investigation into innovative processes...
Structural Studies of Two Aerobrake Heatshield Panel Concepts
Structural sizing and performance data are presented for two different aerobrake hexagonal heatshield panel structural concepts. One concept features a sandwich construction with an aluminum...
Orbital Construction of a NTR Mars Transfer Vehicle
This paper examines a reference Nuclear Thermal Mars Transfer Vehicle (NTMTV) in terms of on-orbit construction. The identification of subassemblies, payload manifesting, on-orbit connections,...
Cargo Transport to the Lunar Surface Using a Three Rotor Sling
The three rotor sling, a momentum transfer device, is described. The dynamics of multi-rotor systems are explained, and the three rotor system is shown to be favored over one and two rotor...
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....
Mobile Continuous Lunar Excavation
The purpose of this paper is to explore the two main problems regarding current approaches to lunar mining and to recommend three candidate solutions which will be shown to have potentially...
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...
Lunar Surface Mining Equipment Study
In response to the Space Exploration Initiative (SEI), a large number of lunar base scenarios have been proposed by various members of the research community. The National Aeronautics...
Ropeway Material Handling Systems for Lunar Mining Sites
