Pattern Formation and Time-Dependence in Flowing Sand
The authors present results for a number of experiments on flowing granular materials and a novel cellular automata model for the flow of these materials when the grains are long and thin....
Investigation of Parametrically-Induced Excitation in Concrete Columns
A mathematical model is developed which accounts for the non-linear material characteristic of concrete members. The axial and transverse motions of concrete columns, are found to be second-order...
Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...
Genesis: The Creation of a Lunar Base
A lunar basing scenario that utilizes lunar resources to manufacture lunar concrete modules is considered. An eleven year basing program, starting with initial robotic exploration and...
Lunar Oasis
The Lunar Oasis emphasizes development toward self-sufficiency in order to reduce dependence on the Earth for resupply and to enable expansion utilizing indigenous resources. The Oasis...
Building a Space Infrastructure: The Reclamation Experience
The third and last duty of the ... commonwealth is that of erecting and maintaining those public institutions and those public works, which, although they may be in the highest degree...
Construction and Development of a Human Base on Mars
Humans on Mars will face many challenges. Possibly the first and one of the longest will be the construction and growth of the base. In this paper a number of techniques are looked at...
Prototype Lunar Base Construction Using Indigenous Materials
A lunar base must be designed to withstand harsh lunar conditions, which include severe internal pressure loads and a high radiation level. Yet to provide for economical and rapid future...
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...
