A Reliability Analysis of Aerospace Structures Subject to Thermal Mechanical and Flight Loads
Aerospace structures are subjected to various flight loads throughout their service life. In certain anticipated missions, significant thermal stresses will be generated through atmospheric...

Incident Solar Flux at Fixed Orientations
Optimal orientations are computed to maximize or minimize the incident solar flux onto surfaces on spacecraft at fixed attitudes. This analysis was motivated by a potential need to optimize...

Manifesting for a Lunar Robotic, Oxygen-Producing Base
Using robotic systems and human supervisory control, a lunar base reasonably be established to achieve full production within five years. Intermittent human presence works in coordination...

Implications of the New Radiation Exposure Limits on Space Station Freedom Crews
Spaceflight unavoidably increases the exposure of astronauts to natural ionizing radiation. Any increase in radiation exposure increases the risk of contracting cancer or inducing genetic...

Managing Cultural Diversity in Orbital Habitats
This paper presents the background, outline, and initial findings of an international project on 'Managing Cultural Diversity in Orbital Habitats'. The purpose...

Artificial Gravity: Human Factors Design Requirements
A major challenge of manned spaceflight is to assure the health, well-being and performance of the space inhabitants. As man ventures beyond Earth's orbit to settle the Moon,...

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...

Alternatives for the U.S. Manned Space Program
There are a number of directions the U.S. space program could take. Should a space station be built? Should a lunar outpost be constructed? Should the U.S. plan a manned trip to Mars?...

National Aero-Space Plane Pioneering New Frontiers
Paper reviews the current status, technology and potential future space launch applications of the joint DOD/NASA National Aero-Space Plane (NASP) program. Key program goals include first...

Seismic Isolation of a Flight Simulator Manufacturing Facility
The corporate headquarters of Evans & Sutherland is located in the University of Utah Research Park which is in Salt Lake City, Utah. A major fault runs through Salt Lake City...

Constraints on Lunar Base Construction
This article discusses the development of scenarios and designs for the construction of a lunar base or network of bases, which will require close attention to the natural and human constraints...

Transportation by Pipelines in Space Colonies
The use of pipelines in space colonies to transport liquid, gas, solids and even passengers is not only feasible but also desirable. For many applications, pipelines offer a number of...

Basing Options for Lunar Oxygen for Manned Mars Missions
The use of lunar oxygen to support lunar space transportation reduces Earth launch mass requirements by a factor of 2. In this paper, the authors show that lunar oxygen can also reduce...

A Space-Based Communications Concept to Support Mars Exploration Missions
Both the Soviet Union and the United States have expressed a desire to conduct further exploration of Mars and both sides have raised the possibility of joint Mars missions. In addition,...

Design Requirements for a Mars Base Greenhouse
One potential method of supplying life support to a manned base on Mars utilizes a Controlled Ecological Life Support System (CELSS). A major component of the CELSS is a plant growth unit...

Radiation Hazards to Space Construction - The Energetic Particle Environments
Many aspects of the space environment are recognized hazards for activities above the Earth's atmosphere. One of the most dramatic hazards is that posed by the diverse energetic...

Telerobotics Design Issues for Space Construction
The efforts of a recent study aimed at identifying key issues and trade-offs associated with using a Flight Telerobotic Servicer (FTS) to aid in Space Station construction phase tasks...

An Overview of the Ease/Access Space Construction Demonstration
With the successful completion of the EASE/ACCESS demonstration, NASA took a significant step toward understanding construction in space. These experiments were performed on November 29...

Space Truss Construction Studies
The ACCESS Shuttle Flight Experiment, designed to evaluate EVA for on-orbit assembly of erectable truss structure, is reviewed and principal results are summarized. In addition, two on-going...

Waste Management: Project Mercury to the Space Station
This paper presents my perceptions of the design of waste management systems for manned space flights. I'll follow the evolution of waste management from the early Mercury...
