Kinetic Interpretations of First Reactivity Experiments on Lunar Basalt Samples
For the first time, water/oxygen production from Apollo program lunar samples has been experimentally demonstrated. The experiments gave extremely encouraging results as all ilmenite was...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...
Lunar Base Aspects for Biotechnology Industry
A lunar base can provide unique services to biotechnology research, development, and production. A lunar location as well as the vacuum environment can protect experiments from contamination...
A Minimum Mars Mission Approach
The purpose of this paper is to identify the mission architecture required to perform a human exploration mission to Mars using a minimum amount of resources. This mission will send three...
A Surface Exploration Vehicle Testbed for Real-Time Control Exerimentation
Current mission scenarios for return to the moon as well as Mars include some robotic systems; for the precursor unmanned mission, these systems will be required to operate under autonomous...
A Space Suit for Productive and Safe Extravehicular Activity (EVA)
An innovative space suit called the Command/Control Pressure Suit (CCPS) is described in terms of productivity and safety. Conceived as a cockpit for Extravehicular Activity (EVA), the...
Future Launch Systems: The Policy Challenge
A review of the literature and discussions with military, commercial, and NASA representatives shows that all users agree we need new systems, but there is no agreement on which to pursue....
Synthetic Estimation of Development Cost of Satellite
An analysis and estimation of life cycle cost (LCC) is one of the important parts of a conceptual study or feasibility study on a satellite....
A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...
Debating Steel - Connection Design
The debate about responsibility for structural-steel-connection design is among the hottest engineering disputes of our generation. Meetings have been held on the subject, articles written...
Engineering R&D Strategy
Accurate data on the levels and focus of U.S. civil engineering-related R&D are important to establish a benchmark from which a knowledge base can be constructed; to highlight...
Preserve and Protect
Historic and landmark structures constructed of unreinforced masonry and stone are among the most vulnerable to strong ground shaking and are often subject to possible collapse. For the...
Safety Assessment of a Chemical Reactor Vessel
The potential explosion loadings on a chemical reactor vessel is described in this paper. The potential loads presented provide a basis for designing spherical storage vessels which will...
The Inelastic Response of an Offshore Platform in Hurricane Andrew
Amoco's Gulf of Mexico South Timbalier 161A platform took a direct hit from Hurricane Andrew in August of 1992, experiencing loads which far exceeded its design load. The platform had...
Nonlinear Collapse of Offshore Jacket Structures
The Joint Industry Tubular Frames Project was established with ten oil industry sponsors to investigate the reserve and residual strength of frames typical of offshore structures. To date...
Concrete Buildings in Regions of High Seismicity
Structural systems for multistory concrete buildings in regions of high seismicity are reviewed. The suitability and certain practical aspects of the systems are discussed. A Uniform Building...
High-Strength Concrete Columns in High-Rise Buildings
Strength and ductility of high-strength concrete columns were investigated by examining available test data. The results are summarized in terms of load and ductility capacities of columns....
Seismic Design of RC Structural Walls with Unsymmetrical Cross-Sections
An overview of seismic design issues and current experimental research for walls with unsymmetrical cross-sections is presented. The experimental studies include approximately 1/4 and...
Behavior of Foundations Subjected to Large Ground Movements
The behavior of twelve linear test foundations above an advancing longwall coal mine panel was observed. Three phases of deformation were observed in the centerline foundations: tension,...
