Update of the Implications of Recent Space Resource Discovery
Immense resources have been discovered in the space near Earth during the last decade. Last August, 1992, one of the resource objects was discovered to contain a key ingredient that might...

Resource Recovery Facilities for Earth Approaching Comets
Mankind's next large resource location may be off the planet. The facilities required for mining and material processing offer interesting concepts for the development of mankind's first...

Mars Terraformation Revisited
This report is a look into the future; not only that of the solar system, but of humans. With the goal of changing Mars into a living planet, we also have to face the change of the human...

A Space Station of Mars
While we are putting stations on the moon and in orbit in this fast changing world of growing scientific knowledge we must look past the step we are currently on to the steps beyond. The...

Construction of a Lunar Base
The United States' space program has the capabilities to build a lunar base, but must build an infrastructure which allows the easy transportation of the construction materials. Once this...

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....

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...
