Steady State Composition with Low Fe?+ Concentrations for Efficient O2 Production by Magma Electrolysis of Lunar Soils
Parameters are estimated for a hypothetical, well stirred, continuous-feed electrolytic cell that converts 20% of a lunar soil feedstock to O2 gas,...
Production of Oxygen by Electro-Reduction of Lunar Ores
Anorthositic Lunar ores contain approximately 42 wt. pct. of oxygen. An electrolytic dissociation of the ore can provide a rich source of gaseous oxygen with silicon, aluminum, calcium,...
A Proposed Methodology for Ranking Space Resource Utilization Processes
A recent survey paper on lunar manufacturing identified 26 initial steps previously proposed as primary routes for lunar processing. Most of these have not been studied in sufficient detail...
Materials and Structures Synergistic with In-Space Materials Utilization
The objective of this paper is to clearly demonstrate the significant advances made in recent months toward actual hardware realizations of various concepts for the utilization of in-space...
Mars Mission Designs: Comparing the Near Term Options
The benefits to be derived from manufacturing chemical rocket propellants from native resources on the Martlan surface are so great that it will almost certainly be a component of any...
Lunar Liquid Oxygen Production Facilities
Production of oxygen beyond Earth's gravity well has been shown to be an economic asset for interplanetary travel using chemical combustion propulsion. Requirements for lunar liquid oxygen...
The Feasibility of Processes for the Production of Oxygen on the Moon
Twenty different processes for the production of oxygen on the Moon have been proposed. An evaluation of their perceived feasibility is presented. The lunar liquid oxygen (LLOX) production...
A Mars 1 Watt Vortex Wind Energy Machine
Ever since Viking I and II landed on the surface of Mars in the summer of 1976, man has yearned to go back. But before man sets foot upon the surface of Mars, unmanned missions such as...
Polycrystalline CdTe Solar Cells for Large-Scale Space Applications
Solar cells are recognized energy sources for use in space. In this talk, the current status of polycrystalline CdTe solar cell development and the potential use of this technology for...
INTERLUNE Concept for Helium-3 Fusion Development
Many considerations suggest that in the 21st Century, deuterium/helium-3 (D-3He) fusion will be the electricity generation system of choice to replace...
Phased Assembly of a European Space Station
This paper discusses a phased assembly approach for a proposed European Space Station utilising a series of constructional payloads that are delivered to orbit in an established sequence...
A Novel Aerobrake Design for a Mars Lander
A flexible/inflatable aerobrake is proposed for delivering small payloads to Mars as an alternative to propulsion landing. Some results that demonstrate feasibility are presented....
Structural Considerations in the Design of a Mars Mission Aerobrake
A new area of civil engineering is emerging. This area will provide structures for outposts on the moon, resource development and exploration of Space. Spacecraft traveling at very high...
On-Orbit Assembly and Refurbishment of Lunar Transfer Vehicles
Initial flights of space-based manned lunar transfer vehicles (LTV) will require some on-orbit assembly and checkout due to mass and volume limitations of the Earth-to-orbit (ETO) launcher....
Tethers and Their Role in the Space Exploration Initiative
This paper addresses some potential applications for tethers in space, and describes a mission designed to deploy a satellite from a Delta II launch vehicle, by NASA's Small Expendable...
The Affordable Space Platform: The STS External Tank
Future development of space requires establishing affordable work platforms in orbit. This paper surveys possible uses of the Space Transportation System's External Tank (ET) to provide...
Back to the Future: A Saturn V-Based Low Earth Orbital Transportation Node
The Space Exploration Initiative requires a heavy-lift launch vehicle to succeed. Reviving the Saturn V represents the best option for regaining heavy-lift. Utilizing the Saturn V's two-stage-to-orbit...
Evolution of the Space Station Freedom Module Pattern
The Space Station Freedom (SSF) is being designed to serve as a permanently manned platform in space to accommodate a growing amount of supported scientific research and, ultimately, to...
Structural Design Methodology of Large Space Structures
This paper discusses considerations and outlines a methodology for structural design of large space structures (LSS) deployed in low earth orbit. It includes definition of mission requirements,...
A Methodology for Development of Spaced-Based Assembly Operations
