The Optimal Selection of Robot Modules for Space Manipulators
Monolithic robot systems are poorly suited to the broad requirements and uncertainties of space automation applications. Designers have considered building many robots, each of which can...

A Novel Gravity Compensation System for Space Robots
Realistic experimental investigation of the behavior of space robots requires simulation on earth of the micro-gravity environment existing in space. This is particularly true due to the...

On the Dynamics and Control of Flexible Orbiting Systems: An Approach with Application
A relatively general formulation for studying the dynamics and control of an arbitrary spacecraft, with interconnected flexible, deployable and articulating structural members, is reviewed...

A New Airlock Approach for Human Exploration
Conceptual design work on the First Lunar Outpost (FLO) mission led to the development of an airlock concept called the `doorlock' which appears quite promising for all aspects of manned...

Analysis of Inflating Habitable Space Structures with neomass (near-Earth-object mass)
The discovery of near Earth objects (NEOs), during August 1992, and that one of them is a dormant comet, dramatically changed the potential availability of near-Earth resources. NEOs provide...

Erectable Truss Hardware for Large Space Structures
The KATLOK connector is a truss structure connector that was designed to be compatible with manual assembly by an astronaut in an extra-vehicular activity (EVA) suit, telerobotic assembly...

Construction Operations on the OUTPOST Platform in Orbit
GLOBAL OUTPOST, Inc., with significant NASA assistance, proposes to place an External Tank (ET) of the space shuttle in orbit for commercial purposes. The OUTPOST Platform is designed...

Interactions Between the Space Station Freedom Attitude Control System and Space Shuttle Remote Manipulator Controller During On-Orbit Assembly Operations
This paper presents the results of dynamics and control interaction analyses involving the Space Shuttle Orbiter, the Shuttle Remote Manipulator System (SRMS), and the Space Station Freedom...

The Effect of Mobile Transporter Motion on the Space Station Attitude Control System
The effect of Mobile Transport (MT) motion on Space Station stability and the performance of the Attitude Control System (ACS) using Control Momentum Gyros (CMGs) is assessed. Analysis...

Space Station Microgravity Analysis and Assessment
The space station will be a platform for microgravity research. For superior microgravity science, the experiment locations must experience very little acceleration in the quasi-steady...

Microgravity Research in a Space Station Environment
A broad class of scientific experiments have evolved which utilize extreme low acceleration environments. A space station can provide such a `microgravity' environment, in conjunction...

Adaptive Space Station Technologies and Systems for a Lunar Surface Return Mission
The current global economic climate, in particular that of the United States, has impacted all aspects of government spending. Wise use of existing, as well as near-term planned, assets...

A Space Station Simulation: EXEMSI '92 A Study on Confinement and Isolation of a Mixed Crew of Four during 60 Days
Manned spaceflight is entering a new era. The next period will be characterized by long duration stays in space and heterogenous crews. EXEMSI '92 was an attempt to study the human-related...

Zero-Gravity Sports Centers
One of the uses that has been proposed for fully reusable launch vehicles is `space tourism', the making of short visits to low Earth orbit by fare-paying passengers. This seems to offer...

Methods to Mitigate Thermally Induced Distortion
The purpose of this paper is to show the magnitude of bending on the Space Station Freedom Navigation Base as induced by thermal expansion and contraction over the operating range -45...

Global Environmental Change: Geoengineering Technology
The `overview effect,' looking at the entire Planet Earth from space, has communicated the reality of the limited extent of our environment and its apparent fragility. Space continues...

Modeling of Interaction of Small Particulates in Earth Orbit
The hazards posed by small debris is an area of increasing concern for all space systems. Depending on the size and relative encounter velocity of small particulates, there are a variety...

Integrated Spacecraft Environments Model (ISEM)
Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...

A Space Station of Mars
While we are putting stations on the moon and in orbit in this fast changing world of growing scientific knowledge we must look past the step we are currently on to the steps beyond. The...

Space Stations Past, Present, and Future
The paper discusses the evolution, present state and future of space stations. Man's interest in the stars led to many inventions and the ultimate launching of the Russian satellite Sputnik,...
