Reducing the Long-Term Effects of Zero-Gravity
Maintaining the physical health of scientists has been a longstanding problem in space flight research. Several ideas have been proposed to solve this problem. These include creating artificial...
Living in Space
Living in space will be the key project for the survival of the human species in the future. The world is becoming more polluted, suffering under the lack of living space, and if people...
A Simple Method of Producing Lunar Soil Simulants for Engineering Studies
This paper suggests that it is possible to obtain large quantities of simulated lunar regolith that can be used for feasibility studies of lunar base construction and excavation machinery...
Feasibility of Dual Technology in Manufacturing Lunar Concrete
This paper presents the feasibility of utilizing different construction materials for probable use on the moon. Furthermore, it is to our advantage to use what is available on the moon...
For the Realization of Lunar Concrete
Since most of the raw materials required to make concrete exist in lunar rocks and soils, concrete is considered as one of the most suitable materials for lunar structures. Author's research...
Production of Lunar Concrete Using Molten Sulfur
A study has been undertaken by the authors and supported by NASA to study the feasibility of using lunar regolith with different binders such as molten sulfur, epoxy or hydraulic cement...
Methodology for Comparing Lunar Settlement Designs
This paper examines a methodology used to compare divergent lunar settlement proposals. It is suggested that the methodology be added to other selection tools for determining which is...
Recycled Engineering Applied to the First Lunar Outpost
Once the proposed Lunar Base configurations obtained by the Undergraduate Research Opportunities Program (UROP) team have been analyzed, a systems study of the usefulness of the specific...
Transferring Construction Technology to the Moon and Back
This paper examines past NASA contributions to the construction industry, analyzes the challenges ahead for space-based construction, cites examples of new technologies currently used...
Lunar Base Construction Using the Reinforce Earth Method with Geotextile
This paper focuses on the construction of layered embankments using regolith and filmy materials (called geotextiles) with a robot machine before setting up of the cylindrical module on...
Construction of Large Lunar Structures by Fusion Welding of Sintered Regolith
Regardless of material used, construction of large lunar structures using indigenous resources is likely to requires joining of simple blocks or pieces. Fusion welding using an optical...
Sintering Bricks on the Moon
Sintering of full-scale 'bricks' from lunar soil simulant materials can be accomplished by radiant heating to 1100?C for approximately 2 hours, followed by slow cooling. Small-scale precompaction...
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...
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....
Spacecab: A Concept for Commercial Human Spaceflight
This paper will describe the Spacecab conceptual design and operational scenario. Spacecab is not necessarily a unique design solution but it does illustrate a design philosophy that differs...
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....
ARIANE-5 Launch Operations Construction and Operation of a New Launch Complex for Lower Cost, Higher Reliability Missions
This paper describes the main criteria driving the evolution of these facilities : launch rate, vulnerability to accidents, reliability and safety, cost optimization and adaptation to...
Puerto Rico Privatizes the Roads
The opening of Puerto Rico's Teodoro Moscoso Bridge in San Juan early in 1994 will usher in a new era of privately financed toll roads. The first product of the 1989 Private...
Effective Project Planning Techniques
Setting tabular and graphic standards for the presentation, storage and handling of project-related data from the start can make the job of managing, scheduling and documenting a project...
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...
