A Robotics Testbed for In-Space Assembly Tasks
The operations testbed of the Center for Space Construction at the University of Colorado is described. This testbed serves as a centralized testing environment for interdisciplinary research...

Wave Propagation in Hyper-Structures
The concept of hyperelement was introduced by E. Kausel and J.M. Roesset, 1977 in connection with the derivation of the dynamic stiffness matrix for layered continuum problems involving...

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...

Biosphere II: Closed Ecological Systems Engineering
This paper provides a general description of the Biosphere II project - a 3.15 acre materially closed ecological system containing tropical rainforest, savannah, marsh, marine, desert,...

Conceptual Design for a Lunar-Base CELSS
Future human exploration is key to the United States National Space Policy goal of maintaining a world leadership position in space. In the past, spacecraft life support systems have used...

Investigation of HVAC Systems in Low Gravity Application
This paper has been developed to identify and summarize the principal areas of investigation necessary to design and install functional HVAC systems in low gravity applications. These...

Preliminary Assessment of the Power Requirements of a Manned Rover for Mars Missions
This paper presents the results of a preliminary study to determine the total mass and power requirements of a Manned Mars Rover. The primary power for the Rover is provided by a Nuclear...

Power for Magma Electrolysis
This paper summarizes qualitative issues of electrical power distribution for near-term lunar facilities. The issues to be discussed were developed during a conceptual study of a Lunar...

The Optimum Dimensions of Radiative Spines
Radiative pin fins (spines) are important in conjunction with heat rejection systems for space applications. In the design of radiators for space applications, spines possessing minimum...

Education: The Future is Now
The United States of America as a nation faces a major challenge in improving its entire educational systems, especially education in mathematics, science, and engineering. Our future...

Designed Experiments: An Interdisciplinary Approach to Space Education
The challenge of space is forcing engineering faculties to re-examine their roles in preparing college graduates to contribute to the space exploration and colonization effort. One of...

Probable Impacts of Space Operations on Air Force Civil Engineering
Consider the bridge from today's space programs and systems to tomorrow's space reality. Current space policy is revoluntionary in nature. Selected space related...

Synthesis of a Space Infrastructure
The Rockwell International 'Integrated Space Plan' consolidates a broad range of near-term and long-range objectives for the development of space. Beginning with...

Columbus Generic Element Management Concept
The concept for largely autonomous onboard management of the ESA Columbus project elements relies on the automation of operational procedures. Reconfigurable items are commanded in sequence...

Normal Accidents and Logistics in Space Operations
Unpredictable systemic accidents, normal accidents, will occur in highly-complex large-scale space systems. To mitigate the catastrophic consequences of normal accidents, containment engineering...

DYCAM: A Computer Aided Engineering Tool for Space Construction Planning
Planning and management of construction activities in space have not received sufficient attention up to the present. Space Station Freedom, a number of large platforms and extraterrestrial...

Black Holes
For many years, scientists have searched the skies for black holes; stars even more massive than white dwarves. As of yet, there have been no 100% sure sightings. Since they do not emit...

Space Power Systems?Radiation: Energy Conversion
Pair production is a way to change a photon, a gamma particle, into matter or energy. It is found that if a photon of energy greater than 1.02 MeV strikes a foil containing a large number...

Challenges and Opportunities in the '90s and Beyond?A U.S. Army Corps of Engineer's Perspective
In the foreseeable future, water resources expenditures will probably be dominated by environmental/water quality concerns. Strong focus is coming to bear on the state of repair, rehabilitation...

Water Resources Infrastructure Review
This paper reviews the three reports forming the basis for the U.S. National Council on Public Works Improvement water resources infrastructure related findings. It also reviews the soon...
