Extraterrestrial Resources: A Perspective from Terrestrial Economic Geology
Terrestrial mining experience indicates that the overwhelming criterion of a potentially economic deposit is its recoverable concentration of the desired mineral or element. These criteria...
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...
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,...
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...
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...
Concrete Construction on the Moon
Building bases on the Moon, according to Space Exploration Initiative, may start in the early 21st century. Concrete, as versatile as it has been, might become the prime material for construction....
Modular Robot Testbed
One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at...
Outpost Service and Construction Robot (OSCR)
The Outpost Service and Construction Robot (OSCR) is proposed as the prime mover of a comprehensive, synergistic approach to extraterrestrial surface construction, mining and transportation...
A New Era in Space Operations
The United States has embarked on a bold new course in space. We are in the process of deploying global missile defenses which promises to help realize an extended era of international...
The Virtual Mission: A Step-Wise Approach to Large Space Missions
The new Virtual Mission concept will provide NASA's Science Program with a powerful new, 'go-as-you-pay,' flexible, and resilient way of accomplishing its science observing program. The...
Advanced Construction Management for Lunar Base Construction?Surface Operation Planner
The unprecedented task of constructing a lunar base could easily overwhelm any existing terrestrial construction management system. Couple this with the overall need for lunar surface...
Advances in Ground Operations for the Next Generation Space Launch Vehicle Programs
For over thirty years, large launch vehicles such as Saturn, Delta, Atlas, and Titan have successfully provided the world with access to space. The emphasis of each of those programs was...
Mars Via the Moon?A Robust Lunar Resources-Based Architecture
A space operations architecture is outlined that uses lunar materials to cost-effectively support Lunar and Mars exploration and operations. This architecture uses a chemically powered...
Utilization of On-Site Resources for Regenerative Life Support Systems at a Lunar Outpost
Regenerative Life Support Systems (RLSS) will be required to regenerate air, water, and wastes, and to produce food for human consumption during long-duration stays on the Moon. It may...
