Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [0₂/90₆]_s...

Thermal Cycling of Thin and Thick Ply Composites
An experimental study was conducted to determine the effects of ply thickness in composite laminates on thermally induced cracking and changes in the coefficient of thermal expansion (CTE)....

Development, Testing and Modeling of Ceramic Composites for Lunar Applications
The procedure referred to as thermal liquefaction allows production of Intermediate Ceramic Composites (ICC) from lunar simulants with various admixtures. For their use as structural materials...

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...

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...

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...

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...

Remote Sensing of Astrofuel^TM
A direct, high-resolution measurement from lunar orbit of the location of high concentrations of ³He in the lunar regolith is needed for the initiation...

The Challenge of Mining He-3 on the Lunar Surface: How All the Parts Fit Together
After the initial confirmation of the existence of He-3 on the lunar surface in 1985, there has been a flurry of activity both in the U.S. and abroad to find the best method of garnering...

Helium-3 on the Moon: Model Assumptions and Abundances
Solar-wind particles are present in the outer few 100 angstroms of each soil particle of the Moon. Of particular interest, are the volatiles hydrogen (40-100 ppm) and helium (5-45 ppm)....

In-situ Extraction of Lunar Soil Volatiles
Techniques for their recovery and utilization of the potentially valuable solar-wind elements embedded in the lunar regolith have been proposed. In order to acquire quantities of ³He...

A Discussion of Nuclear Propulsion in Space Travel
Nuclear thermal propulsion (NTP) is gaining popularity as a safe alternative to conventional propulsion. Such alternatives are desirable to meet the goals of lunar colonization and manned...

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,...

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...

Reduction, Reuse, and Recycling on a Future Lunar Base
The paper addresses the waste management problems on Earth as they relate to a future lunar base and suggests measures to prevent these problems from occurring in the base. Offensive action...

Lunar Mining
Mining the moon for materials that can be used for the advancement of space research would be very profitable. It would be necessary to develop equipment for mining. There would be a need...

JSC-1: A New Lunar Soil Simulant
A new lunar soil simulant, JSC-1, has been developed and characterized under the auspices of the NASA Johnson Space Center. This simulant was produced in large quantities to satisfy the...
