Structures for a Lunar Base
Constructed facilities will play the key role in the establishment of a lunar base. Such a base is essential in the development of the space frontier and the expansion of humans into space....
Structures for the Moon
Lunar structures present new challenges for structural engineers. By articulating lunar conditions in terms of various 'causes,' e.g. high transportation costs...
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...
Design of a Second Generation Lunar Base
We discuss the design of a permanent lunar base of 100 person size which may be able to expand to a base of about 500 person size. We present a preliminary design for a base concept which...
Lunar Oxygen Production from Ilmenite
Carbotek has developed a process for oxygen production from ilmenite-rich lunar deposits to support lunar base operations and large-volume propulsion needs. The reduction of iron oxide...
Plasma Processing of Lunar Ilmenite to Produce Oxygen
In order to make a space industry economic, a reliable extraterrestrial source of oxygen must be identified for immediate use. Lunar ilmenite has recently been considered as a candidate...
Basing Options for Lunar Oxygen for Manned Mars Missions
The use of lunar oxygen to support lunar space transportation reduces Earth launch mass requirements by a factor of 2. In this paper, the authors show that lunar oxygen can also reduce...
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...
Candor Chasma Camp
This paper proposes a camp at Mars, in the Coprates region of the Valles Marineris rift, just below the equator on Candor Mensa 6�-12'S, 73�-30'W. Beginning at...
Homesteading Mars
The author gives serious study to setting up a permanent Martian base during the first or second manned Mars mission. The savings of fuel and equipment for the return trips might pay for...
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...
Response of Advanced Composite Space Materials to Thermal Cycling
In addition to microgravity and lack of atmosphere, the space environment provides intense radiation of both penetrating and nonpenetrating types. This paper focuses on the cyclic radiational...
Fatigue Reliability of Space Structures
This paper develops a methodology for calculating the probability distribution for rainflow cycles in a nonstationary Gaussian process. The up and downcrossing rates are estimated for...
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...
Inflatable Form Construction in Space
In 1973, NASA launched Skylab 1 using a modified third stage of a Saturn V Rocket. This orbital workshop proved to be a success even though problems occurred. This article discusses the...
Spacecraft Environments: Design Considerations
Design, launch, assembly in orbit, and operation of large space-based systems involve much detailed analysis to ensure mission success. The area of contamination control and environmental...
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...
Containerless Coating Processes for Large Space Structures
Large space structures (LSS) in low earth orbit (LEO) must be able to withstand the deleterious effects of in situ ultraviolet radiation, atomic oxygen, and thermal-cycling-induced microcracking....
Differential Gravitional Forces on Large Space Structures
Effects of the differential gravitational forces have been investigated simultaneously on the orbital motion, attitude motion, and axial deformation of a very large axially flexible space...
