Cylindrical Fabric-Confined Soil Structures
Using the local soil as a structural material can greatly reduce the transport requirements for constructing Lunar and Martian surface structures. A fabric-soil structural concept which...

Inflation Concept Development for Inflatable Lunar Structures
Inflatable structures require mechanical equipment to initiate and maintain inflation. Several inflatable structural shapes and forms have been proposed by a number of different authors....

Tripod Crane Concept for Lunar Surface Construction
A construction scheme using three integrated cranes is proposed. Mikulas proposed a lunar crane concept which introduces a set of three cables in order to stabilize the payload. This paper...

Performance-Based Evaluation of Lunar Base Construction Equipment and Methods
Existing literature regarding the selection of lunar base construction equipment and methods is heavily dependent upon qualitative measures for evaluation of equipment concepts. Selection...

Enhancing Decision Analysis Techniques for Lunar Base Construction Research
The usefulness of decision analysis concepts applied to lunar base construction research has been demonstrated [Boles 1990]. During the referenced work the authors realized that further...

The Challenge of Constraining Mass for Planetary Construction
This paper discusses the issue of minimizing the mass required to be delivered from earth for planetary construction. New machinery, methods and concepts are discussed....

Directions for Lunar Construction: A Derivation of Requirements from a Construction Scenario Analysis
This paper provides an initial trade-off study among several lunar construction options available to the Space Exploration Initiative. The relative time effectiveness of Extra-Vehicular...

Uses for Lunar Crawler Transporters
This article discusses state-of-the-art crawler transporters and expresses the need for additional research and development for lunar crawlers. The thrust of the paper illustrates how...

Dust Control Research for SEI
A study, at NASA Johnson Space Center, of dust control requirements for surface habitats has focused on identification of the dust problem, identifying dust control techniques and dust...

Building Lunar Roads?An Overview
Outposts and permanent installations on the moon will need a network of surface roads connecting them. The problem of creating such roads is more challenging than on Earth in most ways,...

Experimental Study of Underground Exploration by Auger Boring on a Mars Rover
A system study was conducted on the possibility of exploring Mars using a Mars Rover, and particular efforts were focused on the underground exploration of Mars by an auger boring machine....

Construction of a Far-Term (2020+AD) Lunar Base
Several case studies have been performed which provide interesting insights into the design and operation of a lunar base. Yet few of these studies have addressed the specific steps which...

Mass and Energy Tradeoffs of Axial Penetration Devices on Lunar Soil Simulant
Axial penetration of the lunar surface was performed to collect soil samples with drive tubes and drill cores on the six successful Apollo missions. Although the pile-driving and drill...

Construction Challenges on Planetary Surfaces
In July 1989 those who advocate a vigorous U.S. space program received a significant boost from the President's declaration that we should return to the Moon, this time to stay, and then...

Indigenous Planetary Construction Material Through Soil Modification
This paper will discuss the theory of soil modification and its potentials for producing planetary construction materials. The authors will also present the results of prelimnary experriments...

Frontloading for Successful Team-Built Projects
A customized, team-buit, Project Management STrategy is having exetraordinary success on a number of very demanding construction projects for the government and private industry. This...

Structural Materials from Lunar Simulants Through Thermal Liquefaction
Thermal liquefaction that allows development of intermediate ceramic composites from a lunar simulant with various admixtures is used to develop structural materials for construction on...

Isotopic Separation of ?He/⁴He From Solar Wind Gases Evolved from the Lunar Regolith
The potential benefits of ³He when utilized in a nuclear fusion reactor to provide clean, safe electricity in the 21st century for the world's inhabitants...

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...

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,...
