Analysis of Space Crane Articulated-Truss Joints
Three articulated-truss joint concepts for the space crane are studied to evaluate their static structural performance over a range of geometric design parameters. Emphasis is placed on...

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...

Constructing Radiation Shields with Textiles for Lunar Applications
The problem of radiation shielding on the lunar surface is significant. The mass required for adequate shielding is enormous and economics would dictate the use of lunar soil for this...

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...

The Application of Open System Architecture to Planetary Surface Systems
This paper investigates the issues that future planet surface activities must confront, defines the basic concepts that provide the basis for establishing an Open System Architecture,...

Lunar Resource Base
A lunar base that exploits local resources to enhance the productivity of a total SEI scenario is discussed. The goals were to emphasize lunar science and to land men on Mars in 2016 using...

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...

Mechanical Properties of Lunar Soil and Simulants
Investigation of the physical and mechanical properties of lunar soil carried out by the USSR and the USA; both in situ and on returned samples, has resulted in considerable information...

Sulfur as a Lunar Resource
Sulfur on the Moon may prove to be a satisfactory replacement in some uses for lighter volatile elements and their compounds. Although sulfur is not richly concentrated on the Moon, it...

Chemical Analysis in Space Exploration: A Lunar-based Chemical Analysis Laboratory (LBCAL)
Many questions need to be answered before humans can be supported for extended periods in space - an environment inimical to terrestrial life. While some questions of a physiological nature...
