Pressure Suit Requirements for Moon and Mars EVA's
In this paper, we examine the influence of pressure suit and backpack designs on astronaut productivity and on the frequency with which EVA's can be conducted during lunar base operations...
An Integrated Human/Plant Metabolic Mass Balance Model
The design and development of Controlled Ecological Life Support Systems (CELSS) in support of future Lunar and Martian bases requires analytical models for evaluating human and biological...
Thermal Investigation of a Large Lunar Telescope
Recent interest in construction of a large telescope on the Lunar surface (Nein and Davis, 1991; Bely, Burrows, and Illingworth, 1989) has prompted this feasibility study of a thermal...
Concept for a Lunar Array for Very Low Frequency Radio Astronomy
We discuss the design considerations relevant to a very low frequency array, to be deployed on the lunar near side during an early expedition. Such an array would operate in the frequency...
Laboratory Evaluation of Footings for Lunar Telescopes
Presented here are the results of laboratory experiments with different footing shapes for lunar telescopes. These experiments used a variety of soils including some to simulate regolith...
Design of a Support and Foundation for a Large Lunar Optical Telescope
NASA is considering a large lunar telescope [LLT] and a smaller diameter precursor telescope experiment on the Moon. The preliminary design of the 16-meter optical aperture is being performed...
Mars Basing
Transportation options for getting humans to and from Mars are understood much better than are the Mars basing options themselves. Current crew mission designs do not yet integrate planetary...
Systems Integration of Lunar Campsite Vehicles
This paper describes the configuration design and subsystems integration resolution for lunar Campsite vehicles and the crew vehicles (CVs) which support them. Briefly stated, this concept...
Towards a Spacefaring Civilization
Three questions are addressed: (1) Is the U.S. a spacefaring nation? (2) Are we a spacefaring civilization? What are the benefits of being one? If we are not, how do we become one? (3)...
A Vision for Planetary Exploration
The Space Exploration Initiative (SEI) is the latest in a series of endeavors which represent humankind's desire to expand its knowledge and sphere of influence. Throughout recorded history,...
An Analysis of Human Performance in Simulated Partial-Gravity Environments
Three unique partial gravity test environments; parabolic flight, water immersion and a mechanical-relief device provide the environment to evaluate human locomotion, reach sweeps, and...
The German Participation in the Soviet MARS 94/96 Mission
The German contribution to the science program of the Soviet MARS 94/96 missions includes 14 experiments or experiment, participations to be placed on the various mission elements: the...
Preliminary Investigation of a Lunar 16 Meter Optical Telescope
The results of a year-long effort to develop a design concept for the structure of a 16 meter lunar optical telescope are presented. Various mounting configurations and mirror configurations...
Internal Pressure in a Lunar Inflatable Structure
Design and construction of a structure on the Moon requires addressing a host of issues not encountered on Earth. A critical design factor is the internal atmospheric pressure necessary...
Design Considerations for Multi-Wheel Aircraft
The available test data for performance of flexible pavements were analyzed using the Boussinesq and elastic layered theories. It was shown that strain criteria could be developed for...
Denver International Airport Fabric Roof Design
The design of Denver's Landside Terminal Complex for the new Denver International Airport, called for some far reaching vision coupled with imaginative building technologies. Because of...
The Design of the Airside Concourses
The growth of commercial air traffic in the United States has resulted in the development of the 'New Denver International Airport.' the airside concourses were designed by joint venture...
The Airport Traffic Control Tower for the New Denver International Airport
Developing a new airport traffic control tower involves many complexities of planning, engineering, and coordination. For the ATCT at the New Denver International Airport, these complexities...
Modeling Nearshore Currents in the Vicinity of the Endicott Causeway, Alaska
The Endicott Causeway connects two oil production islands on the southern side of Stefansson Sound, about 5 km offshore of the Sagavanirktok River delta, to the mainland of the Alaskan...
Impact of Breakwater Removal on Hydrodynamics and Water Quality in Flushing Bay, New York
Hydrodynamic and water quality models were used to simulate the potential effect of removing a breakwater to increase flushing and improve water quality in Flushing Bay, New York City....
