Deepwater Waves and Tsunami Produced by the Impacts of Small Asteroids
Studies of ocean sediments may be used to determine when coastal areas have been hit by tsunamis in the past. Tsunami debris has been found to be associated with the Cretaceous-Tertiary...

A Space Suit for Productive and Safe Extravehicular Activity (EVA)
An innovative space suit called the Command/Control Pressure Suit (CCPS) is described in terms of productivity and safety. Conceived as a cockpit for Extravehicular Activity (EVA), the...

Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...

An Inflatable Antenna for Space-Based Low-Frequency Radio Astronomy
Antennas for a low-frequency orbiting radio telescope must have minimal problems in deployment, a directional beam, and a wide-angle scanning capability. Inflatable antennas with deposited...

Low Frequency Radio Astronomy from Earth or Lunar Orbit
Acquiring data at low frequencies is complicated by the fact that the ionosphere strongly disturbs the data, especially for high-resolution ground-based telescopes. The most viable observational...

Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...

An Ultra-Lightweight Advanced Technology Telescope for Space Applications
We propose a new type of telescope designed specifically for space and lunar applications. The optical reflecting surfaces of the telescope are made by replication onto thin ultra-lightweight...

The Lunar Ultraviolet Telescope Experiment (LUTE)
The Lunar Ultraviolet Telescope Experiment (LITE) is a feasible scientific payload which could initiate a unique ultraviolet (UV) sky survey from the lunar surface prior to our manned...

Gravitational Wave Astronomy and the Lunar Ligo Concept
The preliminary proposal (LaFave and Wilson, 1993, 1992) for emplacing a modest LIGO [ Laser interferometer Gravitational Wave Observatory ] system on the Moon using unmanned robotic landers...

Future Launch Systems: The Policy Challenge
A review of the literature and discussions with military, commercial, and NASA representatives shows that all users agree we need new systems, but there is no agreement on which to pursue....

Space Commercialization: Problems of Law and Policy
This paper focuses on executive and legislative efforts to promote the growth of commercial space industries in the United States. After a discussion of the current, situation and efforts...

Mixed-Use Business Park Developments in Space: A Real-Estate Paradigm
Standard terrestrial business-park development practice is proffered as a realistic organizational model for expanding human activity in Earth orbit. The histories, methods and biases...

The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...

Dynamic Optimization by Small Variation of the System Layout
Dynamic problems have been usually considered in the speed for frequency domain. However, most machines, structures or mechanisms are usually interconnected subsystems, overconstrained...

Spacecab: A Concept for Commercial Human Spaceflight
This paper will describe the Spacecab conceptual design and operational scenario. Spacecab is not necessarily a unique design solution but it does illustrate a design philosophy that differs...

Synthetic Estimation of Development Cost of Satellite
An analysis and estimation of life cycle cost (LCC) is one of the important parts of a conceptual study or feasibility study on a satellite....

ARIANE-5 Launch Operations Construction and Operation of a New Launch Complex for Lower Cost, Higher Reliability Missions
This paper describes the main criteria driving the evolution of these facilities : launch rate, vulnerability to accidents, reliability and safety, cost optimization and adaptation to...

Puerto Rico Privatizes the Roads
The opening of Puerto Rico's Teodoro Moscoso Bridge in San Juan early in 1994 will usher in a new era of privately financed toll roads. The first product of the 1989 Private...

Taking Trash Out of Hiding
Out of sight, out of mind has been the country's solid waste mind-set. But when the $18 million Phoenix Solid Waste Management Center becomes fully operational in April, visitors...

Effective Project Planning Techniques
Setting tabular and graphic standards for the presentation, storage and handling of project-related data from the start can make the job of managing, scheduling and documenting a project...
