An Analysis of an Inflatable Module for Planetary Surfaces
Design and construction of a structure on planetary surfaces requires addressing a host of issues not encountered on Earth. A modular quilted inflatable structure consisting of thin membranes...
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...
Conceptual Design of Modules for a Lunar Base
This paper describes the development of cubically shaped aluminum modules which could be variously arranged to form living and working quarters for a lunar base. The module components...
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...
A Horizontal Inflatable Habitat for SEI
The inflatable habitat described in this paper is a horizontally-oriented cylindrical pneumatic structure. It is part of NASA's ongoing effort to study inflatables as alternative habitats...
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...
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...
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....
Lunar Base Requirements for Human Habitability
This paper presents some of the requirements for lunar surface habitation. Emphasis is placed on human factor and environment-behavior requirements that impact on habitability for medium-duration...
Applying Lessons from Extreme Environments to Solve Problems on Earth and in Space
Extreme environments on Earth and in space test human abilities to adapt, survive and undertake difficult and often dangerous tasks. Hardships and challenges posed by such environments...
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...
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...
Polycrystalline CdTe Solar Cells for Large-Scale Space Applications
Solar cells are recognized energy sources for use in space. In this talk, the current status of polycrystalline CdTe solar cell development and the potential use of this technology for...
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
A flexible/inflatable aerobrake is proposed for delivering small payloads to Mars as an alternative to propulsion landing. Some results that demonstrate feasibility are presented....
Structural Considerations in the Design of a Mars Mission Aerobrake
A new area of civil engineering is emerging. This area will provide structures for outposts on the moon, resource development and exploration of Space. Spacecraft traveling at very high...
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...
Structural Design Methodology of Large Space Structures
This paper discusses considerations and outlines a methodology for structural design of large space structures (LSS) deployed in low earth orbit. It includes definition of mission requirements,...
