The LEO Particulate Environment as Determined by LDEF

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...

Remote Sensing of Astrofuel^TM
A direct, high-resolution measurement from lunar orbit of the location of high concentrations of ³He in the lunar regolith is needed for the initiation...

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,...

The Challenge of Mining He-3 on the Lunar Surface: How All the Parts Fit Together
After the initial confirmation of the existence of He-3 on the lunar surface in 1985, there has been a flurry of activity both in the U.S. and abroad to find the best method of garnering...

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...

Energy Analysis of High Temperature Lunar Manufacturing Processes
This paper presents an energy analysis methodology to optimize the power system requirements for high temperature manufacturing processes on the moon. Power requirement and power system's...

A Summary of the NEPSTP Nuclear Safety Program
The Nuclear Electric Propulsion Space Test Program (NEPSTP) is sponsored by the Ballistic Missile Defense Organization (BMDO) to demonstrate and evaluate the Russian-built TOPAZ II nuclear...

TOPAZ II System Description
The TOPAZ II single-cell thermionic space reactor power system was designed, built and tested by the former Soviet Union (Russia). It has been purchased by the United States (U.S.) for...

TOPAZ II Qualification and Nuclear Testing Program
This paper presents an overview of the Topaz II qualification and nuclear test program. The program combines the joint efforts and resources of Russian and American specialists and organizations...

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...

A Comparison of Propulsion Systems for Space Exploration
There are three promising propulsion systems that might be used for space missions: chemical, direct nuclear, and nuclear electric. Selecting the best system for a mission involves comparing...

A Discussion of Nuclear Propulsion in Space Travel
Nuclear thermal propulsion (NTP) is gaining popularity as a safe alternative to conventional propulsion. Such alternatives are desirable to meet the goals of lunar colonization and manned...

Nuclear Propulsion
In this paper, the possibilities and safety of nuclear propulsion will be discussed and explained. The main focus pertains to the efficiency and safety of this form of propulsion. Nuclear...

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...

Propulsion Systems: Present and Future
Propulsion is the very essence of space travel. There are many types of propulsion. Each type has its advantages and disadvantages. Propulsion systems are constantly being improved just...

Mars Terraformation Revisited
This report is a look into the future; not only that of the solar system, but of humans. With the goal of changing Mars into a living planet, we also have to face the change of the human...
