Utilization of Extraterrestrial Resources

Eight state-of-the-art briefings intended to bring members of the Working Group up to date in technical areas relating to future manned expeditions to the Moon and planets were presented at the Meeting of the Working Group on Extraterrestrial Resources held in Washington, D. C., September 25-26, 1962 by recognized authorities in their respective fields. Since it was felt that the material presented at the meeting would be useful for reference purposes, most of the speakers submitted summaries of their remarks for publication. This document is a collection of the material submitted. Contents: Status of Designs of Lunar Surface Vehicles; Hydroponics or Soilless Culture; Processing of Water on the Moon; Lunar Base Construction; Lunar Rocks as a Source of Oxygen; Water in Lunar Materials; Summary of Apollo and Lunar Logistics System Plans.

Maintainability methodology and maintenance analyses

Initial approach in performing maintainability studies involves detailed description of methodology used. Maintenance analyses are formulated for system, subsystem, and component levels. These are performed to ensure that complete, integrated, logistics system support elements are identified.

Reusable Aerospace Passenger Transport - Study of Incremental Development Approaches Summary Report

This report summarizes the results of studies of economical orbital transportation systems, exploring, in particular , possible options for time - phases and incremental development of such systems. The major conclusions are : 1. Incremental development is a practical way for development of an economic logistics system, minimizing development risk and annual funding, and offering planning flexibility at only a nominal penalty in total systems cost. 2. The most promising first development appears to be that of a re- usable payload carrier with a capacity of 9 to 12 passengers. 3. Systems comparisons show that, for the foreseeable variations of the mission market, a partially reusable concept could bring about most of the program savings that can be expected from reusability at moderate development risk and funding rate. 4. A further development leading to a fully reusable system has high risk and uncertain payoff. Conceivably, at that time, a more advanced concept might be introduced.
