Inflatable Structures of Non-Circular Cross Section
This paper discusses six approaches to achieve an inflatable structure of non-circular cross section for use in lunar base development. Other papers have examined potential multiple uses...
Hedratecture in Severe Climates
There are still vast areas of the world that are almost untouched by human activity. There is need to make access to these regions with special new structures and there is also a need...
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....
Lunar Habitats?Places for People
As part of President George Bush's Space Exploration Initiative, lunar bases or habitats are envisioned for long-term habitation by humans. This paper presents factors that should be considered...
Experimental, Physical and Numerical Modeling of Lunar Regolith and Lunar Regolith Structures
An extensive series of laboratory strength and deformation experiments have been performed on a lunar regloith simulant. Results of these experiments are compared to results from experiments...
The Design of a Permanent Lunar Research Station
The advancement of the United States efforts in space exploration and research requires the establishment of a permanent manned lunar research station. This paper explores the possible...
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...
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...
On-Orbit Chipless Cutting and Tube Welding in Space Station Freedom
Micro-gravity and strict environmental constraints of the laboratory, Habitation and other manned structures which comprise Space Station Freedom demand investigation into innovative processes...
Transient Analysis of Flexible Space Structures
A new approach for numerical analysis of flexible space frames subjected to impact forces is presented. The method is particularly effective in the analysis of large amplitude vibration...
Structural Design of the GN&C Navigation Base for the Space Station Freedom
The Space Station Freedom (SSF) pointing accuracy budget requires that the Guidance, Navigation and Control hardware maintain alignment within ? 0.1 degrees of arc. The ring laser gyros...
A Novel Aerobrake Design for a Mars Lander
