Space Truss
The International Space Station will be more than 310 ft (94 m) long when it is completed sometime in the next decade. The backbone of the structure is a hexagonal truss system that will...

Update of the Implications of Recent Space Resource Discovery
Immense resources have been discovered in the space near Earth during the last decade. Last August, 1992, one of the resource objects was discovered to contain a key ingredient that might...

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...

Alternative Launch Systems Will They Replace the Shuttle?

A Comparison of Propulsion Systems for Space Exploration
There are three promising propulsion systems that might be used for space missions: chemical, direct nuclear, and nuclear electric. Selecting the best system for a mission involves comparing...

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...

Solar Power Satellites
Earth's fossil fuel supply is dropping quickly. A new power source must be developed to save the remaining fuel and control pollution output. Solar power satellites are large satellites...

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...

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...

Large Scale Measurements of Near Surface Orbital Velocities in Laboratory Waves by Using a Surface Following Device

The Kinematic Design of a Robotic Large Space Structure Construction Service
Researchers at the University of Maryland's Robotics Research Lab are applying a kinematic rapid proto-typing methodology to the development of a commercial robotics service for the construction...

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...

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...

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...
