Design of a Second Generation Lunar Base
We discuss the design of a permanent lunar base of 100 person size which may be able to expand to a base of about 500 person size. We present a preliminary design for a base concept which...
Homesteading Mars
The author gives serious study to setting up a permanent Martian base during the first or second manned Mars mission. The savings of fuel and equipment for the return trips might pay for...
Dynamic Analysis of the Joint Dominated Beam
A method is presented herein to determine the vibration modes of the Joint Dominated Beam. An example of a cantilever beam is selected for this purpose. The truss type beam is analysed...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Progressive Impact Damage Assessment in Composite Pressure Vessels
At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads...
Telerobotics Design Issues for Space Construction
The efforts of a recent study aimed at identifying key issues and trade-offs associated with using a Flight Telerobotic Servicer (FTS) to aid in Space Station construction phase tasks...
Animation/Simulation for Construction Planning
The importance of a highly efficient schedule for space construction cannot be overestimated. A detailed scheduling process working closely with design data could reduce costs, minimize...
Robotic Influence in the Conceptual Design of Mechanical Systems in Space and Vice Versa: A Survey
A survey is presented of the methods of constructing structural elements in space by the application of robotic devices. Two fundamentally different approaches to the solution of robotic...
Planar Space Structures
This paper describes a construction system which has a number of practical advantages for the development of space structures. It uses relatively thin materials folded into interpenetrated...
Solar Power Satellite - A Re-Visit
The United States should renew activities investigating the production of baseload electrical power for use on Earth from space. Technology change, world events, and the dictates of the...
Antarctic Research and Lunar Exploration: Useful Parallels
Review of the process of scientific exploration in the Antarctic may provide insights into areas that might pose problems to man when further exploration of the lunar surface is begun....
Strategy for Design and Construction of Lunar Facilities
This paper summarizes the results of a qualitative investigation to identify methods for design and construction of near-term lunar facilities. It is judged that to accomplish such construction...
Space Construction Animator: Functional Requirements
This paper explores the idea of developing integrated design/construction tools. In order to develop suitable computer graphics integrated tools for space construction operations, the...
A Visual Approach for Space Systems Designers
This paper discusses computerized tools that may be used by designers as they approach problem solving related to engineering, construction and operations in space. Tools for space system...
Astrotectonics: An Overview
Astrotectonics is the science of construction in space of both orbital and planetary structures and facilities, as well as orbitally assembled interplanetary spacecraft. The success of...
Air Power Boosts Utility Energy Supplies
Based in part on successful findings of tests, in which compressed air was stored in underground aquifers, Central Illinois Public Service engineers are investigating a type of pumped...
Seismic Risk to Natural Gas and Oil Systems
This paper begins with a brief summary of significant earthquake damage to gas and oil lifeline systems during several earthquakes. Following this discussion, the objectives and major...
New Clarifiers Help Save History
By using clarifiers to upgrade a waste treatment plant, Camp Dresser & McKee were able to utilize the available space so that an historic building existing within the plant could...
From Soft Soils to Heavy Construction
A new construction technique using geotextiles and upward flowing water is bringing heavy construction to soft shores. Two projects�a truck yard in Seagirt, Md., and a containment dike...
