This paper will present an overview of the critical technology needs and the Space Station Freedom (SSF) focused support requirements for the Office of Exploration's (OEXP)...
Low Earth Orbit Infrastructure to Accommodate Manned Lunar Missions
In order to establish bases on the lunar and Mars surfaces, a significant amount of orbital infrastructure including assembly platforms, cryogenic fluids depots, and Space Station Freedom,...
Post-MECO Propulsion System Requirements for Placement of an STS External Tank in Low Earth Orbit
This paper discusses the findings of a series of computer simulations carried out at the National Institute of Standards and Technology to investigate the requirements for powered flight...
MALEO: Modular Assembly in Low Earth Orbit: An Alternate Strategy for Lunar Base Deployment
Modular Assembly in Low Earth Orbit (MALEO) is a new strategy for building an initial operational capability lunar habitation base. In this strategy, the lunar base components are brought...
Automated Manufacturing in Platform-Based Orbital Systems (APROPOS)
As an example of an orbital manufacturing scenario, an automated orbital manufacturing system is designed for the production of turbine blades for high pressure turbines. The target here...
Effects of Initial Conditions on Large Space Structures
Effects of initial conditions of axial deformation (length) and attitude (pitch) angle have been investigated on the subsequent orbital motion, attitude (librational) motion, and axial...
Large Space Systems in Global Change Mitigation
Alternative courses of action are an important aspect of reacting to climate changes, including the greenhouse effect, and other environmental issues such as depletion of the ozone layer....
A Mission to Earth: Global Rural Electrification
No nation can long remain morally strong or economically competitive without an inner purpose. There are many noble projects but few which will both kindle the individual's...
Commercial Launch Facility Economic factors
Launch facility construction, maintenance and modification costs remain a largely invisible part of the cost of putting mass into orbit. The government can lease launch facilities to commercial...
Considerations for the Development of a Commercial Spaceport
Several states and countries are currently reviewing the feasibility of developing a commercial spaceport in their homeland. United Engineers & Constructors Inc. completed an extensive...
Managing Cultural Diversity in Orbital Habitats
