Construction Operations on the OUTPOST Platform in Orbit
GLOBAL OUTPOST, Inc., with significant NASA assistance, proposes to place an External Tank (ET) of the space shuttle in orbit for commercial purposes. The OUTPOST Platform is designed...
Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...
A Space Station Simulation: EXEMSI '92 A Study on Confinement and Isolation of a Mixed Crew of Four during 60 Days
Manned spaceflight is entering a new era. The next period will be characterized by long duration stays in space and heterogenous crews. EXEMSI '92 was an attempt to study the human-related...
Methods to Mitigate Thermally Induced Distortion
The purpose of this paper is to show the magnitude of bending on the Space Station Freedom Navigation Base as induced by thermal expansion and contraction over the operating range -45...
Global Environmental Change: Geoengineering Technology
The `overview effect,' looking at the entire Planet Earth from space, has communicated the reality of the limited extent of our environment and its apparent fragility. Space continues...
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...
Modeling of Interaction of Small Particulates in Earth Orbit
The hazards posed by small debris is an area of increasing concern for all space systems. Depending on the size and relative encounter velocity of small particulates, there are a variety...
Integrated Spacecraft Environments Model (ISEM)
Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...
Energy Analysis of High Temperature Lunar Manufacturing Processes
This paper presents an energy analysis methodology to optimize the power system requirements for high temperature manufacturing processes on the moon. Power requirement and power system's...
A Summary of the NEPSTP Nuclear Safety Program
The Nuclear Electric Propulsion Space Test Program (NEPSTP) is sponsored by the Ballistic Missile Defense Organization (BMDO) to demonstrate and evaluate the Russian-built TOPAZ II nuclear...
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...
The Levitation of Lunar Dust Via Electrostatic Forces
Apollo and Surveyor photographs revealed an unexpected lunar phenomenon that has come to be known as the 'horizon glow'. During lunar sunrise and sunset, a line of light was visible above...
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...
Thermal Regeneration of Spent Lithium Hydroxide
Exploration of planetary surfaces will require portable life-support systems to provide a continuous supply of breathable air. These systems will need to be regenerable in order to support...
A Generic Inflatable Structure for a Lunar/Martian Base
The first steps in the human expansion into space, which inevitably will occur during the next century, consist of the establishment of a human-tended base on the Moon followed by human...
Carbon Formation Theory for Space Oxygen Processes
Production of oxygen from the Martian atmosphere or lunar soil and the recovery of oxygen in manned space environments may include carbon formation from CO as a unit process. Thermodynamic...
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:...
A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...
