Science Operations and Engineering Impacts to Lunar Outpost Design
Recent work by scientists and engineers at the Johnson Space Center ha led to a better understanding of the requirements and interfaces needed at an initial lunar outpost to enable scientific...
Thermal Regeneration of Spent Lithium Hydroxide
Exploration of planetary surfaces will require portable life-support systems to provide a continuous supply of breathable air. These systems will need to be regenerable in order to support...
Kinetic Interpretations of First Reactivity Experiments on Lunar Basalt Samples
For the first time, water/oxygen production from Apollo program lunar samples has been experimentally demonstrated. The experiments gave extremely encouraging results as all ilmenite was...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
Lunar Base Aspects for Biotechnology Industry
A lunar base can provide unique services to biotechnology research, development, and production. A lunar location as well as the vacuum environment can protect experiments from contamination...
A Minimum Mars Mission Approach
The purpose of this paper is to identify the mission architecture required to perform a human exploration mission to Mars using a minimum amount of resources. This mission will send three...
A Surface Exploration Vehicle Testbed for Real-Time Control Exerimentation
Current mission scenarios for return to the moon as well as Mars include some robotic systems; for the precursor unmanned mission, these systems will be required to operate under autonomous...
A Space Suit for Productive and Safe Extravehicular Activity (EVA)
An innovative space suit called the Command/Control Pressure Suit (CCPS) is described in terms of productivity and safety. Conceived as a cockpit for Extravehicular Activity (EVA), the...
Low Frequency Radio Astronomy from Earth or Lunar Orbit
Acquiring data at low frequencies is complicated by the fact that the ionosphere strongly disturbs the data, especially for high-resolution ground-based telescopes. The most viable observational...
Future Launch Systems: The Policy Challenge
A review of the literature and discussions with military, commercial, and NASA representatives shows that all users agree we need new systems, but there is no agreement on which to pursue....
The History and Present Status of Microwave Aircraft
The history of microwave-powered aircraft is reviewed from the point of view of interaction between the technology of beamed microwave power transmission and the applications for it. the...
Dynamic Optimization by Small Variation of the System Layout
Dynamic problems have been usually considered in the speed for frequency domain. However, most machines, structures or mechanisms are usually interconnected subsystems, overconstrained...
Synthetic Estimation of Development Cost of Satellite
An analysis and estimation of life cycle cost (LCC) is one of the important parts of a conceptual study or feasibility study on a satellite....
Cables Over the Mississippi
As the designer of the Great River Bridge over the Mississippi between Gulfport, Ill. and Burlington, Iowa, Sverdrup Corp., St. Louis, had to find a way to connect the new five-lane crossing...
Engineering R&D Strategy
Accurate data on the levels and focus of U.S. civil engineering-related R&D are important to establish a benchmark from which a knowledge base can be constructed; to highlight...
