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,...

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'...

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...

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...

Phased Assembly of a European Space Station
This paper discusses a phased assembly approach for a proposed European Space Station utilising a series of constructional payloads that are delivered to orbit in an established sequence...

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,...

On-Orbit Assembly of Large Space Structures: A Mars Aerobrake Mock-up Study
As design requirements for space structures become larger in dimension, the issues of shipping and assembling these structures in space become more critical. One example of such a structure...

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...

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
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...

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....

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...

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,...

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...

The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...

Composite Materials for Structures on Planetary Surfaces
Development of structures for planetary surface environments depends upon the use of the most appropriate materials. Advanced composite materials are apparently the best candidates for...

Simple and Efficient Methods to Produce Construction Materials for Lunar and Mars Bases
A microwave heating method and a cold press method are proposed as simple ways to produce construction materials on the Moon and Mars. The present experiment on the microwave heating method...
