Onboard Image Processing With Transputers
A transputer based onboard computer for planetary vehicles is being designed in the KFKI Research Institute for Particle and Nuclear Physics (RMKI), Budapest, Hungary. In this paper we...

Fiber Optic Chemical Sensors on Mars
A fiber optic chemical sensing instrument is described that will measure the reactivity of the martian soil and atmosphere. The self-contained instrument monitors reflectivity changes...

Transfer Vehicle Sizing for Missions to Mars
The purpose of this study is to analyze the interactions between mission and vehicle design parameters, and determine how the selection of a particular trajectory and transit time affects...

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...

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...

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...

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...

Dynamic Loading of a Rigid Frame Bridge
The objective of this paper is to investigate the dynamic response of a rigid frame bridge to two trucks (side by side) passing over the rough bridge deck. The rigid frame bridge is designed...

Wind Deflection Probability Analysis
A statistical analysis is performed which analyses the probability of various magnitudes of deflections of a cable-stayed roof occurring due to wind uplift. Extensive wind analyses were...

Floor to Wall Anchors in Historic Brick Buildings
The poster presentation at the Structures' Congress details a retrofit analysis performed on the Gilroy Historic Commercial Building, which was instrumented during the Loma Prieta Earthquake....

Space Frame Solution for the Design of Large Pyramid Structures
This paper presents the engineering design methodology, structural analysis, system detailing, and installation procedures for a large span space frame structure currently under construction...

Roof Space Frame Design of the C.K.S. Airport Passenger Terminal II
This article attempts to provide a description of the characteristics of the Second Terminal Airport. To comply with the functional requirement of the magnificent facade and spacious design...
