Site Constraints for a Lunar Base
A rigorous site plan is a prerequisite for quantitative analyses of lunar base operations. The development of such a site plan, done for a detailed lunar base study (RLSO, 89), is described...
Lunar Base Elements Designed for Robotic Operations
Equipment concepts developed for a study of robotic lunar surface operations are presented. The concepts were evolved together with a consistent robotic buildup and operations scenario;...
Manifesting for a Lunar Robotic, Oxygen-Producing Base
Using robotic systems and human supervisory control, a lunar base reasonably be established to achieve full production within five years. Intermittent human presence works in coordination...
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...
Composting for Lunar Agriculture
Alternative technologies for the microbially mediated biological oxidative transformation (composting) of human wastes and other organic wastes are presented. Batch mode and continuous...
Fluid Behavior Considerations for Waste Management in Low-Gravity Environments
Design of waste recycling systems for spacecraft requires a knowledge of fluid behavior in microgravity. As gravity is reduced, phenomena usually ignored in the One-G environment of earth...
Synthesis of a Space Infrastructure
The Rockwell International 'Integrated Space Plan' consolidates a broad range of near-term and long-range objectives for the development of space. Beginning with...
Level of Recycling Effectiveness
The Level Of Recycling Effectiveness (LORE) scale is presented. It is a conceptual framework for evaluating recycling and other alternative strategies of meeting needs in space activities....
Black Holes
For many years, scientists have searched the skies for black holes; stars even more massive than white dwarves. As of yet, there have been no 100% sure sightings. Since they do not emit...
Key Environmental Development Issues
Those in the business community who may be affected by environmental factors include: buyers and sellers of businesses, existing facilities, and real property; their lenders, brokers,...
Developing a Wastewater Plan for an Urbanizing Area?The Case of Johnson County, Texas
Johnson County, Texas, is located south of Ft. Worth, Texas, and is influenced by the entire Dallas-Ft. Worth Metroplex, which has a population of more than 3 million people. In 1988 the...
A Travel Time Template for Water Body Field Surveys
A LOTUS 1-2-3 spreadsheet application has been developed to help plan water body surveys. The template calculates travel times between sampling stations and outputs a time schedule for...
Wastewater Balance for Storage Pond at Land Treatment Site
Land application is an established method for treating municipal wastewater in the United States. Most land application operations include on-site facilities to store wastewater during...
Water for Houston: The Wallisville Case
The multipurpose Wallisville project included an industrial water supply for Houston. The project was nearly 70 percent complete when environmentalists succeeded in stopping construction...
Groundwater Contamination from an Unlined, Poorly Capped Landfill
This paper presents a case study of groundwater and surface water contamination from a major, unlined, and poorly capped municipal landfill located in Western Washington. The landfill...
A Rational Basis for Determining Safety of Containment
Design of waste containment facilities may follow one of three tacts: (1) the liner and cover systems may have prescribed components of predetermined minimum thicknesses and hydraulic...
Measuring Benefits of Water Supply Projects
Various approaches are used to determine the value of water supply projects. Deterministic methods will lead to biased valuation of additional supplies of water. Calculation of risk premium...
Water for Texans?Using the Water Development Fund
This paper is presented to provide information on the Texas Water Development Fund. The Fund is available as a source that can provide financial assistance to political subdivisions of...
Unmixing Mixed Waste
A thermal treatment process successfully converted sludge classified as hazardous chemical/radioactive mixed waste to low specific activity radioactive waste at the National Guard Armory...
Bio Bonanza?
Bioremediation was used on a portion of the Exxon oil spill, causing the popular press to take notice of the ability of bugs to eat away at oil and, possibly, toxic wastes. The Alaskan...
