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...
Fluid Behavior Considerations for Waste Management in Low-Gravity Environments
Design of waste recycling systems for spacecraft requires a knowledge of fluid behavior in microgravity. As gravity is reduced, phenomena usually ignored in the One-G environment of earth...
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...
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...
Lunar Base Power Requirements, Options & Growth
A preliminary study of lunar base scenarios and associated power requirements has recently been completed. Minimum power levels of 50-100 kW are required for 'science-only'...
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...
Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....
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...
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...
A Prototype Model for Human/Automation Trade-offs
Future space construction missions will involve both human and machine constructors. Selection of the optimum constructor mix requires a model of constructor capabilities and requirements....
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 Research Facility Options
On a long duration manned mission to Mars, the physiological changes caused by microgravity may be counteracted by artificial gravity. This paper evaluates several different classes of...
Variable Gravity Research Facility: A Concept
One of the most exciting missions NASA is currently studying is a human mission to Mars. Mission scenarios range from 20 day surface expeditions to permanent human bases on the martian...
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,...
Partial Gravity: Human Impacts on Facility Design
Partial gravity affects the body differently than earth gravity and microgravity environments. The main difference from earth gravity is human locomotion; while the main difference from...
Hedratecture and Artificial Gravity
There is a need, according to the National Commission On Space, to develop three critical space facilities: A Space Base, A Variable-Gravity Research Facility, and a Lunar Surface Outpost....
New Interdisciplinary Engineering Design Course in Planetary Materials and Resource Utilization
A new senior/graduate-level course addressing topics of planetary materials and resource utilization was given at Michigan Technological University in the spring of '89. The...
Working on the Moon: The Apollo Experience
Work experience gained during the Apollo missions suggests that lunar base productivity can be enhanced through careful attention to suit design, repair capabilities, equipment design...
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...
