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...
Design Criteria for an Underground Lunar Mine
Underground excavation and construction techniques have been well developed terrestrially and provide an attractive option for lunar mining and habitat construction. The lunar mine, processing...
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...
Sintering of Lunar Glass and Basalt
Sintering of the regolith has been proposed as a method for producing construction materials from local resources at a lunar base. Applications for lunar 'bricks' include road beds, foundations,...
Explosive Forming of Aluminum-Lithium Alloys
This paper proposes the use of explosive forming to form large, near net shape components for HLLV propellant tanks and structures in meeting this need. Combining with high strength to...
The Analysis Related to the Impact of Composite Panels
In analyzing experiments under impact loading, a dynamic model is needed to solve for the deflections and strains as functions of time. For composites, where shear deformation can be very...
Simple and Efficient Methods to Produce Construction Materials for Lunar and Mars Bases
A microwave heating method and a cold press method are proposed as simple ways to produce construction materials on the Moon and Mars. The present experiment on the microwave heating method...
Steam Injection System for Lunar Concrete
Since January 1989, the Department of Civil Engineering at the United States Air Force Academy has been conducting research on the use of concrete for constructing permanent facilities...
Concrete Construction on the Moon
Building bases on the Moon, according to Space Exploration Initiative, may start in the early 21st century. Concrete, as versatile as it has been, might become the prime material for construction....
On-Orbit Robotics Assembly and Operations of a Nuclear Mars Transfer System
This paper presents an operations concept and associated scenarios for assembly in Earth orbit of a manned Mars vehicle. The assembly of a Rockwell-Spar reference spacecraft configuration...
Robotic On-Orbit Fueling of SEI Vehicles
Space Exploration Initiative (SEI) missions may involve the assembly and then fueling of vehicles in locations other than on the surface of the Earth. For example, fueling of the Mars...
Telerobotic Field Geologist: Preliminary Results of a Feasibility Study
We conducted three laboratory studies to explore the feasibility of developing a telerobot to perform planetary field geology. In all, 72 college students attempted to match each of 15...
Modular Robot Testbed
One approach to non-terrestrial construction involves the use of small, inexpensive, modular robots rather than expensive one-of-a-kind construction tools. The Modular Robots Testbed at...
Outpost Service and Construction Robot (OSCR)
The Outpost Service and Construction Robot (OSCR) is proposed as the prime mover of a comprehensive, synergistic approach to extraterrestrial surface construction, mining and transportation...
Robotics in SEI Terrestrial Launch Site Operations
This paper addresses work performed at Rockwell International's Space Systems Division, Downey, California. Future Space Exploration Initiative (SEI) missions will require terrestrial...
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...
The Initial Exploration of Mars: Rationale for a Return Mission to Chryse Planitia and the Viking 1 Lander
The concepts behind planning a landing site on Mars are discussed. Based on the engineering constraints and the scientific objectives which will likely be imposed on the first few missions...
Operations Planning for Space Station FREEDOM?and Beyond
Automated planning and electronic execution systems offer tremendous potential for enhancing operations aboard Space Station FREEDOM (SSF). To exploit this potential, the Operations Planning...
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...
