Design Concepts for a Lunar Electric Power System
This paper discusses the results of ongoing research and the evaluation of various concepts for transmission, distribution and utilization of electric power for a lunar liquid oxygen plant....

On-Orbit Assembly and Refurbishment of Lunar Transfer Vehicles
Initial flights of space-based manned lunar transfer vehicles (LTV) will require some on-orbit assembly and checkout due to mass and volume limitations of the Earth-to-orbit (ETO) launcher....

Back to the Future: A Saturn V-Based Low Earth Orbital Transportation Node
The Space Exploration Initiative requires a heavy-lift launch vehicle to succeed. Reviving the Saturn V represents the best option for regaining heavy-lift. Utilizing the Saturn V's two-stage-to-orbit...

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 Mine Feasibility Study
This paper describes a lunar surface mine, and demonstrates the economic feasibility of mining oxygen from the Moon. The mine will be at the Apollo 16 landing site. Mine design issues...

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...

Beneficiation and Comminution Circuit for the Production of Lunar Liquid Oxygen (LLOX)
A complete lunar beneficiation and comminution circuit has been designed that requires no air or fluid locks for feed introduction or egress, with the exception of a vapor pyrolysis station....

Transfer of Terrestrial Technology for Lunar Mining
Terrestrial mining equipment was evaluated for development of concepts and their application to lunar-based mining operations. The major operational differences between terrestrial and...

Spiral Mining for Lunar Volatiles
Lunar spiral mining, extending outward from a periodically mobile central power and processing station represents an alternative for comparison with more traditional mining schemes. In...

Preliminary Design of an Underground Lunar Mine
This paper presents a mining engineering viewpoint on the design and construction of an underground lunar mine. Upon completion, the facility will serve as a lunar habitat. Ore removed...

Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...

Lunar Mining—Surface vs. in Situ—A Comparative Study
Surface mining and in situ mining are briefly reviewed and compared. It is verified that the inherent advantages of in situ mining over surface ruining point out that in situ mining should...

Sintering of Lunar Glass and Basalt
Sintering of the regolith has been proposed as a method for producing construction materials from local resources at a lunar base. Applications for lunar 'bricks' include road beds, foundations,...

Vacuum Melting and Mechanical Testing of Simulated Lunar Glasses
Lunar silicate glasses may possess superior mechanical properties compared to terrestrial glasses because the anhydrous lunar environment should prevent hydrolytic weakening of the strong...

Strength and Fracture of Glass in the Lunar Environment
Due to the lack of water on the moon, the effects of hydrolytic depolymerization - stress corrosion cracking - will be nonexistent in glasses produced and used on the moon. This would...

Mechanical Properties of Compacted Lunar Simulant Using New Vacuum Triaxial Equipment
Mechanical stress-strain-strength properties of Arizona Lunar Simulant (ALS) are investigated by using a newly developed vacuum triaxial device that allows compaction under different initial...

Steam Injection System for Lunar Concrete
Since January 1989, the Department of Civil Engineering at the United States Air Force Academy has been conducting research on the use of concrete for constructing permanent facilities...
