Laboratory Testing of Mechanical Rock Bolts
An analytical solution to a boundary value problem of a clamped cylindrical panel with anti-symmetric angle-ply laminations subjected to transverse loads is presented. Sanders' kinematic...

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...

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...

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...

Structural Characterization of an Articulated-Truss Joint
A first generation space crane articulated-truss joint was statically and dynamically characterized in a configuration which approximated an operational environment. The articulated-truss...

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,...

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...

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,...

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'...

Materials and Structures Synergistic with In-Space Materials Utilization
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...

Modeling and Analysis of Doubly Curved Aerobrake Truss Structures
Recent studies have indicated that vehicles designed for a piloted mission to Mars may have their initial Earth Orbit mass reduced by nearly a factor of two if aerobraking is used rather...
