Explosion excavation technology may become a valuable tool for economic and efficient base station construction on extraterrestrial bodies. Criteria for explosives which can safely be...
The Expandable Platform as a Structure on the Moon
This discussion will show how the expandable platform, initially designed for earth, is translated for use on the moon, and how it answers a multitude of problems while it is used for...
A Space-Based Communications Concept to Support Mars Exploration Missions
Both the Soviet Union and the United States have expressed a desire to conduct further exploration of Mars and both sides have raised the possibility of joint Mars missions. In addition,...
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...
Active Control of Flexural Vibrations in Beams
The feasibility of using piezoelectric actuators to control the flexural oscillations of large structures in space is investigated. Flexural oscillations are excited by implusive loads...
Planetary Base Inflatable Form Construction
The use of the inflatable form (IF) structure has been practiced in the concrete industry for more than a decade. This article proposes the use of a double-walled IF for the Phase I construction...
Radiation Hazards to Space Construction - The Energetic Particle Environments
Many aspects of the space environment are recognized hazards for activities above the Earth's atmosphere. One of the most dramatic hazards is that posed by the diverse energetic...
Animation/Simulation for Construction Planning
The importance of a highly efficient schedule for space construction cannot be overestimated. A detailed scheduling process working closely with design data could reduce costs, minimize...
Robotics Research for Construction in Space
Research in construction robotics, terrestrial or otherwise, has focused on issues which are broadly pertinent to space applications. Construction robotics, as addressed by this writer,...
Space Station - New Venture/Old Problem
Four key operations-related costs are associated with the Space Station: (1) transportation, (2) data management, (3) sustaining engineering, and (4) integrated logistics. Life cycle cost...
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...
Nuclear Electric Propulsion for Near-Term Space Missions
Potential uses of nuclear electric propulsion (NEP) for earth-orbit, lunar, and martian missions are analyzed. NEP systems allow a higher payload mass fraction than chemical systems. NEP...
Solar Water Heater for NASA's Space Station
This paper describes an investigation of the feasibility of using a solar water heater for NASA's Space Station. During the investigation computer codes were developed to...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...
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...
Plasma Reactor Waste Management Systems
The University of North Dakota is developing a plasma reactor system for use in closed-loop processing which includes biological, materials, manufacturing, and waste processing. Direct-current,...
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,...
