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...

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...

Lunar Mining
Mining the moon for materials that can be used for the advancement of space research would be very profitable. It would be necessary to develop equipment for mining. There would be a need...

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...

Design Criteria for Lunar Construction Equipment
It is anticipated that lunar installations will, from the beginning, require moving and assembly of components and the use of lunar regolith as a construction material. The functional...

Coupling Translation and Rocking Motions
In the design of concrete block foundations for rotating and reciprocating machines, it is important to avoid resonant conditions. Therefore, accurate determination of the frequencies...
