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...
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....
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...
Commercial Launch Facility Economic factors
Launch facility construction, maintenance and modification costs remain a largely invisible part of the cost of putting mass into orbit. The government can lease launch facilities to commercial...
Power for Magma Electrolysis
This paper summarizes qualitative issues of electrical power distribution for near-term lunar facilities. The issues to be discussed were developed during a conceptual study of a Lunar...
Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....
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...
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...
New Interdisciplinary Engineering Design Course in Planetary Materials and Resource Utilization
A new senior/graduate-level course addressing topics of planetary materials and resource utilization was given at Michigan Technological University in the spring of '89. The...
Working on the Moon: The Apollo Experience
Work experience gained during the Apollo missions suggests that lunar base productivity can be enhanced through careful attention to suit design, repair capabilities, equipment design...
A Cost Study of Concrete Production on the Moon
In proposing and evaluating a construction system for a lunar base, the question of cost would be the most important one. Although it is not possible to conduct a detailed cost study at...
Probabilistic Basis for Managing Maintenance
The paper discusses a procedure based on component failure probabilities, consequences of failure, and risk associated with loss of system. Aging effect of structures and equipment on...
The New Generation of Pipeline Rehabilitation
The new advancements in pipelines reconstruction technologies now permit total sewer system rebuilding of collectors, drainlines, manholes, service laterals, and force mains without excavation....
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,...
The Spirit of Bandera?An Experiment in Inter-Agency Team-Building
An experiment to improve intergovernmental cooperation in water resources planning and management was initiated by the Southwestern Division, U.S. Army Corps of Engineers, in 1988 at Bandera,...
Considerations for a Multiple-Use Stormwater Detention Facility
A 60-year-old neighborhood provides the unusual setting for the City of Tulsa's Turner Park-Will Rogers High School Stormwater Detention Facility. The 20-acre site is located...
Is There a Future for Vacuum Sewers?
Vacuum sewers collect and transport sanitary sewage using pressure difference rather than gravity as the primary motive force. Compared to conventional gravity sewers, they use smaller...
Using an Index Stream to Make Instream Flow Decisions
The paper discusses development of an Integrated Operating Plan (IOP) that uses an unregulated (natural) stream in the upper Cedar basin as an index of overall hydrologic status of the...
