Evaluation of Processing Options for Lunar Oxygen Production
Recent work on space resource utilization has lead to the identification of certain modifications of previously proposed processes which can be properly characterized as 'second generation'...
Materials and Structures Synergistic with In-Space Materials Utilization
The objective of this paper is to clearly demonstrate the significant advances made in recent months toward actual hardware realizations of various concepts for the utilization of in-space...
Mars Mission Designs: Comparing the Near Term Options
The benefits to be derived from manufacturing chemical rocket propellants from native resources on the Martlan surface are so great that it will almost certainly be a component of any...
INTERLUNE Concept for Helium-3 Fusion Development
Many considerations suggest that in the 21st Century, deuterium/helium-3 (D-3He) fusion will be the electricity generation system of choice to replace...
Beneficiation and Comminution Circuit for the Production of Lunar Liquid Oxygen (LLOX)
A complete lunar beneficiation and comminution circuit has been designed that requires no air or fluid locks for feed introduction or egress, with the exception of a vapor pyrolysis station....
Strength and Fracture of Glass in the Lunar Environment
Due to the lack of water on the moon, the effects of hydrolytic depolymerization - stress corrosion cracking - will be nonexistent in glasses produced and used on the moon. This would...
Extraction of Potable Water from Urine for Space Applications
A regenerative technology capable of managing water and wastewater on-board long-term manned space platforms is essential if the Bush Administration's Space Exploration Initiative (SEI)...
Space Station & Lunar/Mars Life Support Research
The first part of this paper will report on the tests now being conducted by the Environmental Control and Life Suport Systems (ECLSS) at Marshall Space Flight Center. The findings of...
Regenerative Life Support Technology Challenges for the Space Exploration Initiative
Regenerative life support systems have been identified as one of the critical enabling technologies for future human exploration of space. This discipline encompasses processes and subsystems...
A Systems Approach to Water Recycling Research
Because of the cost of Earth resupply, water recycling from wastewater is a critical enabling technology for long duration space missions. The need and the fact that water quality is not...
Plot-scale Field Experiment of Surface Hydrologic Processes with EOS Implications
Plot-scale hydrologic field studies were initiated at NASA Marshall Space Flight Center to a) investigate the spatial and temporal variability of surface and subsurface hydrologic processes,...
Regulatory Law and Policy to Support Space Mining
Adaptation of modern mining law principles, such as those embodied in the U.S. General Mining Law of 1872, would protect mineral resource interests in space. A good illustration of a closely...
Rocket Fuel to Earth Orbits from Near-Earth Asteroids and Comets
The analysis describes an architecture to bring 10,000 tons units of rocket fuel ore, propellant and construction mass back to low Earth orbit from newly discovered near-Earth comets or...
In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...
Uniform Traffic Impact Assessment Studies?A Case History of Riverside County, California
A publication was issued by the Transportation Department of Riverside County, California, in December of 1989 which required all traffic impact studies performed for new development to...
Urban Transportation Management?Jersey City, New Jersey
This paper will describe the multi-year process undertaken to implement physical roadway improvements and transportation management policies in a constrained urban environment. Specifically...
Colgate Palmolive Transportation Impact Case Study
The Colgate Palmolive Company owns eleven city blocks of land in the Exchange Place area of downtown Jersey City, New Jersey. Colgate Palmolive operated manufacturing facilities on their...
Lagrangian Transport Simulation Using Video Images to Store and Retrieve Parameters
A new technique based on Video Images for Storing and Retrieving parameters (VISR) and its application to model pollutant transport using the Lagrangian discrete parcel method is presented....
3-D Particle Tracking for the New York Bight
This paper describes the development and testing of a three-dimensional particle tracking model for the New York Bight. A number of particle tracking options have been developed to predict...
An Experimental Model Using a Graphical User Interface
This paper describes a program named Plume which runs on a microcomputer. The intended function of the program is to enhance an investigator's understanding of the estuarine environment...
