Evaluating Lunar Base Conceptual Designs
A large number of competing lunar base conceptual designs have been proposed in recent years. The range of assumptions and technologies used in these designs makes comparison difficult....
Design and Technology Assessment of Three Lunar Habitat Concepts
Three manned lunar habitat concepts, designed to support a crew of four for 28-30 days, are presented. Two concepts are based on Space Station Freedom structural elements and the third...
The Feasbility of Using Solar Optics for Lunar Base Lighting
This paper is a summary of research conducted to establish the feasibility of using solar optics in reduced gravity environments, particularly a lunar base. The research was funded by...
Tensile-Integrity Structural Concepts for the Lunar Surface
This paper suggests the use of tension cable structures of a particular type, Tensegrity structures, for a lunar base. Tensegric shells can be a system of bars and cable net. The shell...
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...
Cables and Cranes for a Flexible Lunar Transportation System
This paper will discuss the results of preliminary research on a cable-based transportation system for the moon. The paper will address the principles of cableway design and will present...
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...
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....
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...
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...
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...
A Modified Sulfate Process to Lunar Oxygen
A modified sulfate process which produces oxygen from iron oxide-bearing minerals in lunar soil is under development. Reaction rates of ilmenite in varying strength sulfuric acid have...
Power Sources for Lunar Bases
Working and living on the Moon requires artificial power sources both to operate equipment and to maintain life. This paper briefly surveys the power sources designed or proposed to support...
Design Concepts for a Lunar Electric Power System
This paper discusses the results of ongoing research and the evaluation of various concepts for transmission, distribution and utilization of electric power for a lunar liquid oxygen plant....
