Dust Control Research for SEI
A study, at NASA Johnson Space Center, of dust control requirements for surface habitats has focused on identification of the dust problem, identifying dust control techniques and dust...
Building Lunar Roads?An Overview
Outposts and permanent installations on the moon will need a network of surface roads connecting them. The problem of creating such roads is more challenging than on Earth in most ways,...
Modeling and Analysis of Doubly Curved Aerobrake Truss Structures
Recent studies have indicated that vehicles designed for a piloted mission to Mars may have their initial Earth Orbit mass reduced by nearly a factor of two if aerobraking is used rather...
Simple and Efficient Methods to Produce Construction Materials for Lunar and Mars Bases
A microwave heating method and a cold press method are proposed as simple ways to produce construction materials on the Moon and Mars. The present experiment on the microwave heating method...
Outpost Service and Construction Robot (OSCR)
The Outpost Service and Construction Robot (OSCR) is proposed as the prime mover of a comprehensive, synergistic approach to extraterrestrial surface construction, mining and transportation...
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...
Space-Based Assembly Sequence Formulation for Evaluation of Large Orbital Assemblies
The challenges associated with constructing interplanetary spacecraft and space platforms in low earth orbit are such that it is imperative that comprehensive, preliminary process planning...
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...
Roof Management Alternatives for Aging Launch Infrastructure
This paper describes a Roof Management System approach to better cope with aging and deteriorating infrastructure support facilities at our national spaceports. It describes facility conditions...
The New Munich Airport?Planning, Construction and Opening of a New International Turnstile Airport in Europe
The new Munich airport that began operations just recently dates back to the mid-1950. The paper discusses the general expansion plan which includes site selection; runway system planning;...
Soft Touch People Mover Central Control
The people mover central control systems perform many automatic functions, are built with off-the-shelf redundant hardware, include advanced color graphics and touch screen operator interfaces,...
Airport Landside Management: An Unique Airport Specialty
Air transportation has become a common and preferred method of travel, resulting in an ever increasing number of air passengers. The significant growth has resulted in unique and never...
Traffic Data Collection: What Really Needs to be Done?
The collection of 'existing' traffic data such as the 24-hour counts, turning movement counts, driveway volumes, and vehicle classification counts near the proposed project site becomes...
A Guideline for Determining Minimum Threshold Requiring Traffic Impact Studies
Over the years, a number of localities have developed and adopted some form of traffic impact assessment (TIA) guidelines. As part of this study, an informal survey conducted showed that...
The Foundation for a Successful Traffic Impact Analysis
