Environmental Hardening of a Mobile-Manipulator System for Nuclear Environments
The research report involves the radiation hardening of a commercially-available, mobile robot, the REMOTEC ANDROS. This hardening effort will culminate in the availability of a mega-rad...

A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...

Thermal Response in Antenna Under Laser Irradiation
This investigation focuses on the thermal response of two objects under medium-intensity continuous-wave (CW) laser irradiation: (1) a homogeneous slab and (2) a complex electronic component,...

Overview of Space Environmental Effects
The natural environment for low Earth orbit subjects satellites to various forms of damage, ranging from particulate impacts, ultraviolet light, atomic oxygen erosion and charged particle...

Roles of the Lunar-Solar Power System In Development of the Resources of Greater Earth for Mankind
The proposed Lunar-Solar Power (LSP) System collects solar power on the moon. The power is converted to beams of microwaves and transmitted to fields of microwave receivers on Earth that...

A Practical Application of Concession Schemes to Space Energy Projects
It has been shown in previous papers and studies that some of the financing schemes involving a mix of private and government funds, which are used for terrestrial large infrastructures,...

Helium-3 on the Moon: Model Assumptions and Abundances
Solar-wind particles are present in the outer few 100 angstroms of each soil particle of the Moon. Of particular interest, are the volatiles hydrogen (40-100 ppm) and helium (5-45 ppm)....

In-situ Extraction of Lunar Soil Volatiles
Techniques for their recovery and utilization of the potentially valuable solar-wind elements embedded in the lunar regolith have been proposed. In order to acquire quantities of 3He...

Inter-stellar Propulsion: The Need for Speed
Interstellar travel is certainly one of mankind's next step to reach for the stars. Four ideas for interstellar propulsion are discussed in this paper: the Orion Project, Deep Space Ramjets,...

Nuclear Propulsion: Safety Measures and Concerns
Since nuclear fission was discovered, many potential uses for it have been found. One such application of fission is nuclear propulsion systems in space ships; however, the elements resulting...

Propulsion Systems for Future Space Exploration
There are many types of propulsion that are being considered for future space travel needs. These include nuclear, solar sail, magnetoplasmadynamic (MPD) thrusters, and laser propulsion...

Solar Power Satellites
Earth's fossil fuel supply is dropping quickly. A new power source must be developed to save the remaining fuel and control pollution output. Solar power satellites are large satellites...

Methodology for Comparing Lunar Settlement Designs
This paper examines a methodology used to compare divergent lunar settlement proposals. It is suggested that the methodology be added to other selection tools for determining which is...

Engineering Implications of Levitating Lunar Dust
In this paper an attempt is made to provide a physical understanding of these various phenomena and their long-term effects on the lunar environment. This understanding is then applied...

Lunar Base Construction Using the Reinforce Earth Method with Geotextile
This paper focuses on the construction of layered embankments using regolith and filmy materials (called geotextiles) with a robot machine before setting up of the cylindrical module on...

Construction of Large Lunar Structures by Fusion Welding of Sintered Regolith
Regardless of material used, construction of large lunar structures using indigenous resources is likely to requires joining of simple blocks or pieces. Fusion welding using an optical...

Optical Waveguide Solar Energy System for Lunar Material Processing
This paper summarizes a study of the optical waveguide (OW) solar energy system for lunar material processing. In the OW solar energy system, solar radiation is collected by the concentrator...

The Lunar Ultraviolet Telescope Experiment (LUTE)
The Lunar Ultraviolet Telescope Experiment (LITE) is a feasible scientific payload which could initiate a unique ultraviolet (UV) sky survey from the lunar surface prior to our manned...

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...
