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...
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...
Design Criteria for Lunar Construction Equipment
It is anticipated that lunar installations will, from the beginning, require moving and assembly of components and the use of lunar regolith as a construction material. The functional...
Efficient Path Planning Strategies for Unmanned Rover Vehicles
Path planning strategies are studied using an optimization model. Four main sub-models are discussed that contribute to the computing of minimum energy vehicle path planning. These are:...
Onboard Image Processing With Transputers
A transputer based onboard computer for planetary vehicles is being designed in the KFKI Research Institute for Particle and Nuclear Physics (RMKI), Budapest, Hungary. In this paper we...
Deepwater Waves and Tsunami Produced by the Impacts of Small Asteroids
Studies of ocean sediments may be used to determine when coastal areas have been hit by tsunamis in the past. Tsunami debris has been found to be associated with the Cretaceous-Tertiary...
Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...
An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy
Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited...
The Lunar Ultraviolet Telescope Experiment (LUTE)
The Lunar Ultraviolet Telescope Experiment (LITE) is a feasible scientific payload which could initiate a unique ultraviolet (UV) sky survey from the lunar surface prior to our manned...
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....
Space Commercialization: Problems of Law and Policy
This paper focuses on executive and legislative efforts to promote the growth of commercial space industries in the United States. After a discussion of the current, situation and efforts...
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...
Design of Mat Foundation for Egg Shape Digesters
Two levels of ground motion, the Maximum Probable Earthquake and the Maximum Credible Earthquake, were considered in designing the 2.5 million gallon egg shape digesters and their combined...
Bridge Rail Impact Forcing Functions
Bridge rails are designed according to AASHTO standards with a static 10-kip (44.5 kN) lateral load. The computer programs BARRIER VII and COSMOS are used to determine the deflections...
Representation and Processing of Design Standards: a Bifurcation between Research and Practice
There have been attempts to develop representations of design standards and procedures for computing representations of the design standard on which computations are based. However, within...
Impediments to the Implementation of Seismic Isolation
There are over 400 civil engineering structures, worldwide, that have been constructed using the principles of seismic isolation, and 70 of these are in the United States. Although use...
Qualification System for Building Engineers in Japan
