Spacecraft Wall Design for Orbital Debris Impact
This paper describes a method for obtaining the optimal rise angle of corrugated bumpers for the design of space structures in the event of an on-orbit impact. The procedure determines...
Distributional Information for Ejection Fragments
Due to lack of experience of building structures on the lunar surface and the variability that will exist in the loading as well as the structural resistance, it is suggested that initial...
Erectable Truss Hardware for Large Space Structures
The KATLOK connector is a truss structure connector that was designed to be compatible with manual assembly by an astronaut in an extra-vehicular activity (EVA) suit, telerobotic assembly...
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...
The Effect of Mobile Transporter Motion on the Space Station Attitude Control System
The effect of Mobile Transport (MT) motion on Space Station stability and the performance of the Attitude Control System (ACS) using Control Momentum Gyros (CMGs) is assessed. Analysis...
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...
The Potential for the Department of Defense to Use Space-Based Remote Sensing to Support DOD and Other Government Agencies' Environmental Programs
This paper describes the potential for the Department of Defense (DOD) to support other government agencies in the management of national and worldwide environmental programs. The DOD...
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...
Is It Possible to Colonize Mars?
Is it possible to colonize the planet Mars? A planet that is believed to be the most clement planet in the solar system, next to Earth. Despite the fact that it is a very clement planet,...
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...
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...
Space Exploration: Getting a Handle on Why?
The two prominent economic issues facing the U.S. today are competitiveness and the huge federal deficit. Economics being the counter-intuitive science that it is, a reasonable exploration...
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...
Habitat Configuration Evaluation Criteria for Moon/Mars
The purpose of this paper is to identify the methodology, evaluation criteria, criteria definitions for evaluating surface habitat configuration concepts for the Moon and Mars. The main...
Science Operations and Engineering Impacts to Lunar Outpost Design
Recent work by scientists and engineers at the Johnson Space Center ha led to a better understanding of the requirements and interfaces needed at an initial lunar outpost to enable scientific...
