Wave Propagation in Hyper-Structures
The concept of hyperelement was introduced by E. Kausel and J.M. Roesset, 1977 in connection with the derivation of the dynamic stiffness matrix for layered continuum problems involving...

Space Construction: A CSI Perspective
This paper outlines the control structure interaction (CSI) problem for space construction engineers. An overview of the Control Astrophysics and Structures Experiment in Space (CASES)...

An Introduction to Pressurized Volumes in Space
Space habitation designers come from diverse backgrounds. As it is human nature to emphasize that which is familiar, habitat design is strongly influenced by the designer's...

Space-Based Control of the Climate
The expected global greenhouse warming of 2 ?C may be reversed by a space-based screen that intercepts 3% of the incident solar radiation. Space-based devices may also mitigate the ozone/UV...

A Mission to Earth: Global Rural Electrification
No nation can long remain morally strong or economically competitive without an inner purpose. There are many noble projects but few which will both kindle the individual's...

Antarctic Testbed for Extraterrestrial Operation and Technology
A remote and harsh environment, Antarctica has areas which are more similar to the Moon and Mars than anywhere else on Earth. The physical similarities, coupled with strong parallels between...

A Center for Extraterrestrial Engineering and Construction (CETEC)
The Center for Extraterrestrial Engineering and Construction (CETEC) has been envisioned as an organization, a center of knowledge and information, and a set of experimental test facilities....

Biosphere II: Closed Ecological Systems Engineering
This paper provides a general description of the Biosphere II project - a 3.15 acre materially closed ecological system containing tropical rainforest, savannah, marsh, marine, desert,...

Conceptual Design for a Lunar-Base CELSS
Future human exploration is key to the United States National Space Policy goal of maintaining a world leadership position in space. In the past, spacecraft life support systems have used...

National Aero-Space Plane Pioneering New Frontiers
Paper reviews the current status, technology and potential future space launch applications of the joint DOD/NASA National Aero-Space Plane (NASP) program. Key program goals include first...

Considerations for the Development of a Commercial Spaceport
Several states and countries are currently reviewing the feasibility of developing a commercial spaceport in their homeland. United Engineers & Constructors Inc. completed an extensive...

Lunar Base Power Requirements, Options & Growth
A preliminary study of lunar base scenarios and associated power requirements has recently been completed. Minimum power levels of 50-100 kW are required for 'science-only'...

A Prototype Model for Human/Automation Trade-offs
Future space construction missions will involve both human and machine constructors. Selection of the optimum constructor mix requires a model of constructor capabilities and requirements....

Managing Cultural Diversity in Orbital Habitats
This paper presents the background, outline, and initial findings of an international project on 'Managing Cultural Diversity in Orbital Habitats'. The purpose...

Artificial Gravity Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...

Variable Gravity Research Facility: A Concept
One of the most exciting missions NASA is currently studying is a human mission to Mars. Mission scenarios range from 20 day surface expeditions to permanent human bases on the martian...

Artificial Gravity: Human Factors Design Requirements
A major challenge of manned spaceflight is to assure the health, well-being and performance of the space inhabitants. As man ventures beyond Earth's orbit to settle the Moon,...

Partial Gravity: Human Impacts on Facility Design
Partial gravity affects the body differently than earth gravity and microgravity environments. The main difference from earth gravity is human locomotion; while the main difference from...

Hedratecture and Artificial Gravity
There is a need, according to the National Commission On Space, to develop three critical space facilities: A Space Base, A Variable-Gravity Research Facility, and a Lunar Surface Outpost....

Education: The Future is Now
The United States of America as a nation faces a major challenge in improving its entire educational systems, especially education in mathematics, science, and engineering. Our future...
