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...
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...
Optimum Design of Laminated Composites
The increased demand for high strength, light weight materials that function successfully in high temperature environments has caused the effective development of laminated composites...
Telerobotic Field Geologist: Preliminary Results of a Feasibility Study
We conducted three laboratory studies to explore the feasibility of developing a telerobot to perform planetary field geology. In all, 72 college students attempted to match each of 15...
Modular Robot Testbed
One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at...
The Virtual Mission: A Step-Wise Approach to Large Space Missions
The new Virtual Mission concept will provide NASA's Science Program with a powerful new, 'go-as-you-pay,' flexible, and resilient way of accomplishing its science observing program. The...
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...
A Facility for Training Space Station Astronauts
The Space Station Training Facility (SSTF) will be the primary facility for training the Space Station Freedom astronauts and the Space Station Control Center ground support personnel....
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...
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...
Geographical Information System (GIS) Technology in Global Environmental Evaluation?An Overview
The Land Analysis Team at the Construction Engineering Laboratory is enhancing the GRASS software package to deal with global environmental questions. CERL has implemented the basic software,...
The Wide-Angle Optoelectronic Stereo Scanner WAOSS for the Soviet Mars 94/96 Missions
The Wide-Angle Optoelectronic Stereo Scanner WAOSS is anticipated for the Soviet Mars 94/96 missions. Starting from the tasks of WAOSS as a part of the TV complex ARGUS, the paper describes...
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...
Using Simulation to Evaluate On-Orbit Construction Operations
As the NASA Space Exploration Initiative (SEI) program contemplates a permanent presence on both the Lunar and Martian soil, the necessity for On-Orbit Construction of the Earth-to-Lunar/Martian...
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...
Minneapolis/St. Paul International (MSP) Part 150 Implementation Design Overview
In February 1991, Matropolitan Airports Commission (MAC) selected the consulting team of Aviation Planning Inc., Wyle LAboratories Inc. and the Center for Energy and the Urban Environment...
Design Considerations for Multi-Wheel Aircraft
The available test data for performance of flexible pavements were analyzed using the Boussinesq and elastic layered theories. It was shown that strain criteria could be developed for...
