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....

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...

Cargo Transport to the Lunar Surface Using a Three Rotor Sling
The three rotor sling, a momentum transfer device, is described. The dynamics of multi-rotor systems are explained, and the three rotor system is shown to be favored over one and two rotor...

Extraterrestrial Resources: A Perspective from Terrestrial Economic Geology
Terrestrial mining experience indicates that the overwhelming criterion of a potentially economic deposit is its recoverable concentration of the desired mineral or element. These criteria...

Mobile Continuous Lunar Excavation
The purpose of this paper is to explore the two main problems regarding current approaches to lunar mining and to recommend three candidate solutions which will be shown to have potentially...

Lunar He-3 Mining: Improvements on the Design of the UW Mark II Lunar Miner
One of the minor consituents of the solar wind which has been implanted in the lunar regolith over its several billion year history, is helium 3 (He-3), a rare isotope of helium which...

Lunar Surface Mining Equipment Study
In response to the Space Exploration Initiative (SEI), a large number of lunar base scenarios have been proposed by various members of the research community. The National Aeronautics...

Ropeway Material Handling Systems for Lunar Mining Sites
The establishment of permanent lunar sites will be a requirement for future space explorations during early missions into space as well as long term. During all stages it will be necessary...

On the Beneficiation and Comminution of Lunar Regolith
A major concern in the area of planning for future lunar missions and for establishing a lunar base is the selection of a chemical process for liberation of oxygen from lunar regolith...

Beneficiation and Comminution Circuit for the Production of Lunar Liquid Oxygen (LLOX)
A complete lunar beneficiation and comminution circuit has been designed that requires no air or fluid locks for feed introduction or egress, with the exception of a vapor pyrolysis station....

Transfer of Terrestrial Technology for Lunar Mining
Terrestrial mining equipment was evaluated for development of concepts and their application to lunar-based mining operations. The major operational differences between terrestrial and...

Spiral Mining for Lunar Volatiles
Lunar spiral mining, extending outward from a periodically mobile central power and processing station represents an alternative for comparison with more traditional mining schemes. In...

Preliminary Design of an Underground Lunar Mine
This paper presents a mining engineering viewpoint on the design and construction of an underground lunar mine. Upon completion, the facility will serve as a lunar habitat. Ore removed...

Lunar Mining—Surface vs. in Situ—A Comparative Study
Surface mining and in situ mining are briefly reviewed and compared. It is verified that the inherent advantages of in situ mining over surface ruining point out that in situ mining should...

Vacuum Melting and Mechanical Testing of Simulated Lunar Glasses
Lunar silicate glasses may possess superior mechanical properties compared to terrestrial glasses because the anhydrous lunar environment should prevent hydrolytic weakening of the strong...

Mechanical Properties of Compacted Lunar Simulant Using New Vacuum Triaxial Equipment
Mechanical stress-strain-strength properties of Arizona Lunar Simulant (ALS) are investigated by using a newly developed vacuum triaxial device that allows compaction under different initial...

A New Era in Space Operations
The United States has embarked on a bold new course in space. We are in the process of deploying global missile defenses which promises to help realize an extended era of international...

SEI In-Space Operations and Support Challenges
The initial architectures and mission concepts for Space Exploration Initiative (SEI) are being studied to expand the manned space exploration capability. To support assessment of operational...

Mitigation of Dust Contamination During EVA Operations on the Moon and Mars
The Space Exploration initiative is charting a new course for human exploration of the Moon and Mars. Advances in EVA system have been identified as being critical for enabling long-duration...

Operations Analysis for a Large Lunar Telescope
With the launch of the Hubble Space Telescope a new generation of science optical observatories was made a reality. Astronomers and scientists have long seen space as having inherit advantages...
