A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...
Extraterrestrial Applications of Solar Optics for Interior Illumination
The major purpose of this paper is to introduce a terrestrial technology that we believe has potential extra-terrestrial applications. The technology is Solar Optics, which is subdivided...
Design Requirements for a Mars Base Greenhouse
One potential method of supplying life support to a manned base on Mars utilizes a Controlled Ecological Life Support System (CELSS). A major component of the CELSS is a plant growth unit...
Power Systems for Production, Construction Life Support, and Operations in Space
As one looks forward to mankind's future in space, it becomes obvious that unprecedented amounts of power will be required for the exploration, colonization, and exploitation...
Supercritical Water Oxidation: Space Applications
The process of Supercritical Water Oxidation (SCWO) is approaching terrestrial commercialization for the destruction of toxic and hazardous waste chemicals. The technology appears promising...
Development of a Two-Stage Membrane-Based Wash-Water Reclamation Subsystem
A two-stage membrane-based subsystem was designed and constructed to enable the recycle of wash waters generated in space. The first stage is a fouling-resistant tube-side-feed hollow-fiber...
Waste Management: Project Mercury to the Space Station
This paper presents my perceptions of the design of waste management systems for manned space flights. I'll follow the evolution of waste management from the early Mercury...
Wastewater Recycle/Reuse: Lessons-Learned from USA-CERL Research and Development
Ultimate acceptance of water recycle/reuse by the scientific community is a function of rigorous data collection and successful demonstration regarding health effects. An uncomplicated,...
Gas Recycling: A Bioregenerative Life Support System
The prospect of a lunar or earth-orbiting space station raises the question of life support for long periods of time with little or no support from earth. The cost of lifting supplies...
Potential Application of Space Station Technology in Lunar Bases and Manned Mars Missions
To meet the goals of its Space Station program, NASA is developing a large set of improved space systems capabilities. In areas such as power generation and distribution, on-board data...
Engineering, Construction, and Operations in Space
This book includes over 100 papers providing in-depth discussions of space policy, extraterrestrial basing, space stations and orbiting structures, and areas of special interest. Outposts...
Underwater Testing in the Development of EVA Support Systems
The ability to simulate realistic zero-g conditions on Earth is of prime importance in determining if various orbital operations associated with extravehicular activity (EVA) can actually...
Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....
The Briny Deep Comes Ashore
Amusement park attractions are not all fun and games. More than 10 years of planning by dozens of firms went into the Living Seas Pavilion at Walt Disney's Epcot Center. The...
Fracture-Mechanics-Based Fatigue Life Estimate
Fatigue lives of tee-shaped weldments are estimated using fracture mechanics concepts and crack growth rate data. Fracture mechanics is used to develop an approximate expression for stress...
A Fatigue Study of Prestressing Strand
Strand fatigue data reported in the literature and also from recent tests were combined to form a data base of strand fatigue data which was analyzed using regression analysis techniques....
Microcomputer Applications for Pavements
The Federal Highway Administration (FHWA) has been active in exploring expanded microcomputer applications with the goal of improving efficiency and benefits to the public through reducing...
Preliminary Design and Construction Plan for an Ocean Wave Energy Conversion System
A preliminary design and construction plan for a prototype wave energy conversion system is described. While the design methodology and construction procedures are intended for generic...
Disney Engineers Voyage to the Deep
The main show at the Living Seas Pavilion, part of Walt Disney Production's EPCOT Center, Lake Buena Vista, Fla., is a visit to a tropical coral reef deep under the ocean....
Life Cycle Analysis
Of all the infrastructure elements, pavement performance has probably received more research than any. Similarly, there has been more application of pavement research. The concepts that...
