A Methodology for Development of Spaced-Based Assembly Operations
Designing and constructing a large space-based science facility requires the integration of constraints and design variables with assembly operations. Development of such a facility requires...
Extraterrestrial Resources: A Perspective from Terrestrial Economic Geology
Terrestrial mining experience indicates that the overwhelming criterion of a potentially economic deposit is its recoverable concentration of the desired mineral or element. These criteria...
Lunar Surface Mine Feasibility Study
This paper describes a lunar surface mine, and demonstrates the economic feasibility of mining oxygen from the Moon. The mine will be at the Apollo 16 landing site. Mine design issues...
Lunar Surface Mining Equipment Study
In response to the Space Exploration Initiative (SEI), a large number of lunar base scenarios have been proposed by various members of the research community. The National Aeronautics...
Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...
The Effect of Multiple Compliant Layers at the Fiber-Matrix Interface on Residual Thermal Stresses in Metal Matrix Composites
The large mismatch in thermoelastic properties of the fiber and matrix phases in advanced metal matrix composites, coupled with high consolidation temperatures, produces severe residual...
An Operational Evaluation Process for Long-Duration Mission Habitats in Space
In preparation for long-duration manned spaceflight into the 21st Century, the ergonomical and psychological aspects of space habitat architectures are being investigated in Europe. Used...
Pressure Suit Requirements for Moon and Mars EVA's
In this paper, we examine the influence of pressure suit and backpack designs on astronaut productivity and on the frequency with which EVA's can be conducted during lunar base operations...
LIAC: A Closed Ecosystem Research Facility
A preliminary design for a closed research facility capable of supporting multispecies and ecosystem level experiments is presented. This project will support NASA's Controlled Ecological...
An Integrated Human/Plant Metabolic Mass Balance Model
The design and development of Controlled Ecological Life Support Systems (CELSS) in support of future Lunar and Martian bases requires analytical models for evaluating human and biological...
SALSA: A Lunar Submillimeter-Wavelength Array
A conceptual design is described for a lunar submillimeter-wavelength interferometer called SALSA, a Synthesis Array for Lunar Submillimeter Astronomy. The intent is to describe SALSA...
Design of a Support and Foundation for a Large Lunar Optical Telescope
NASA is considering a large lunar telescope [LLT] and a smaller diameter precursor telescope experiment on the Moon. The preliminary design of the 16-meter optical aperture is being performed...
Mars Basing
Transportation options for getting humans to and from Mars are understood much better than are the Mars basing options themselves. Current crew mission designs do not yet integrate planetary...
Towards a Spacefaring Civilization
Three questions are addressed: (1) Is the U.S. a spacefaring nation? (2) Are we a spacefaring civilization? What are the benefits of being one? If we are not, how do we become one? (3)...
A Vision for Planetary Exploration
The Space Exploration Initiative (SEI) is the latest in a series of endeavors which represent humankind's desire to expand its knowledge and sphere of influence. Throughout recorded history,...
An Analysis of Human Performance in Simulated Partial-Gravity Environments
Three unique partial gravity test environments; parabolic flight, water immersion and a mechanical-relief device provide the environment to evaluate human locomotion, reach sweeps, and...
Preliminary Investigation of a Lunar 16 Meter Optical Telescope
The results of a year-long effort to develop a design concept for the structure of a 16 meter lunar optical telescope are presented. Various mounting configurations and mirror configurations...
Object Oriented Spacecraft Architecture
This paper describes an architecture for simplifying the spacecraft design and maintenance process: Object Oriented Spacecraft Architecture. Like object oriented programming, the strategy...
Internal Pressure in a Lunar Inflatable Structure
Design and construction of a structure on the Moon requires addressing a host of issues not encountered on Earth. A critical design factor is the internal atmospheric pressure necessary...
Characteristics of High-Speed Runway Exits for Airport Design
This paper addresses some of the geometric design and operational characteristics of high-speed runway exists. Lateral and longitudinal runway constraints limiting the use of high-speed...
