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...

Laboratory Investigations of Low Earth Orbit Environmental Effects on Spacecraft Materials
Operations in low earth orbit (100-500 km) must take into consideration the highly oxidative character of the environment. Partial pressures in the range of 10-6-10-7...

The Role of a Mobile Transporter in Large Space Structures Assembly and Maintenance
Large space structures require a vehicle to support assembly, operations, and maintenance. These vehicles may be designed for specific tasks or for general use throughout the life of the...

Logistics Support of Space Facilities
The logistic support of space facilities is described, with especial attention given to the problem of sizing the inventory of ready spares kept at the space facility. Where possible,...

Preliminary Analysis of Fire Suppression Methods for the Space Station
The choice of a fire suppression system for the space station remains open. Several alternatives have been suggested, each with particular advantages and disadvantages. The problem is...

The Role of Welding in Space Maintenance and Repair
The nature of future space missions will result in increased incidence of degradation, damage, and wear of critical or expensive hardware. In many terrestrial applications welding provides...

Pacific Space Port
The concept of the Pacific Space Center advocated by Mr. Tetuso Kondo (member of the House of Representatives, former Director General of the Economic Planning Agency) and Dr. Tatsuo Yamanaka...

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...

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...

Air Safety—Programs and their Effectiveness
Airplane accidents have always had considerable media attention, particularly, when they involve large numbers of fatalities. Ever since the Airline Deregulation Act of 1978 and the air...

Astrotectonics: An Overview
Astrotectonics is the science of construction in space of both orbital and planetary structures and facilities, as well as orbitally assembled interplanetary spacecraft. The success of...

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...

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...

Structural Optimization Using Astros and Stars Software

Stabilizing Winglet Pair for Slender Bridge Decks
This paper describes the effectiveness, as an aerodynamic damper, of a pair of winglets mounted parallel to, and clear from, bridge decks that might otherwise be aeroelastically unstable....

The Use of Microcomputers to Perform Airport Emission Inventories
The authors found the use of LOTUS 1-2-3, a microcomputer spreadsheet package that permitted easy calculation of emissions and easy revision of data for studying options in aircraft types,...

Terrain Analysis From Space Shuttle Photographs of Tibet
Several Space Shuttle missions obtained false color and large format, high resolution, black and white stereo photography at an approximate scale of 1:800,000. In addition to available...

The Noise Mitigation Plan for Stapleton Airport
In March 1984, seven communities in the vicinity of Denver's Stapleton International Airport completed a year-long study of methods to reduce the adverse noise effects from...

Texas Hiplex—A Summary
Beginning in 1974, a new, concerted effort was undertaken by the Federal government, in cooperation with various High Plains states - including Texas - and local entities, to gain a better...

Monitoring the Chesapeake Bay Fish Spawning Grounds with Aerostats and Remote Sensing Equipment
A brief review is given of the effects of acid rain and other pollutants on the fish spawning grounds in the Chesapeake Bay area. Given the need for improved monitoring of the Bay and...
