To help design and construct human habitats for Earth orbit, the moon, and Mars, NASA is turning to teams of experts in academia and private industry, including civil and structural engineers. The ideas...

A SAR Is Born: How a Cold War Era Technique Is Reinventing Deformation Monitoring from Earth’s Orbit
The space race gave birth to a remote sensing technique known as synthetic aperture radar (SAR) that could be used for everything from tracking militaries to mapping the surface of the moon, all the while...

City in Orbit
An architecture firm envisions how to merge space and terrestrial construction by using an orbiting asteroid as the “foundation” for a megatall tower....

Eyes in the Heavens: Satellite Technologies in Remote Site Monitoring
Installation and maintenance of instrumentation to monitor geotechnical projects in remote locales is usually more challenging than sites in urban areas for both technical and logistical reasons. In most...

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...

The Orbital Criterion of Defining Discrete Waves and Its Relationship with Sea Wave Periods

GPS-Based Control for Space Vehicle Rendezvous
The recent advent of Differential Carrier Phase Global Position System (GPS) sensing has made it possible to determine relative positions of GPS receiver-equipped systems to less than...

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...

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...

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...

Optical Scatter From a Space Craft Mirror Due to Microscopic Impacts
This article addresses the issue of how micrometeoroid and man made debris in the space environment can adversely change the optical resolution of a mirror. The study used an algorithm...

Spacecraft Wall Design for Orbital Debris Impact
This paper describes a method for obtaining the optimal rise angle of corrugated bumpers for the design of space structures in the event of an on-orbit impact. The procedure determines...

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...

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...

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...
