The problem of point-to-point radio communication on the moon is discussed, and equations and curves are presented to estimate power requirements in lunar communication systems.Assuming a smooth surface, consideration is given to ground wave attenuation over both layered and non-layered grounds, antenna ground losses in situations where ground screens are impractical, noise level estimates in the receiving system, and the effects on propagation of possible lunar ionospheres.An example of the calculation of required power for a particular communication system is given, and further studies are suggested.

This report summarizes a portion of the results from a grant at Auburn University to study the electrical and thermal energy management for lunar facilities. Over the past year (June 1989 to May 1990) the following topics have been investigated: June 1989 to November 1989 - Literature survey, assessment of lunar power needs, and overview study of the requirements of a lunar power system; November 1989 to April 1990 - Develop models for the study of dc electrical power transmission lines for the lunar surface; March 1990 to May 1990 - Develop models for the study of ac electrical power transmission lines for the lunar surface. Because of the large amount of information in the model development and application to a wide parameter space this report is being bound separately. This report specifically contains the model development and parameter study for dc electrical power transmission lines. The end of the funding year (May 1990) will conclude with an annual report including the literature survey, the overview of the requirements of a lunar power system, and summaries of the dc and ac models of electrical transmission lines.

A human lunar outpost, under NASA study for construction in the 2020's, has potential requirements to transfer electric power up to 50-kW across the lunar surface from 0.1 to 10-km distances. This power would be used to operate surface payloads located remotely from the outpost and/or outpost primary power grid. This paper describes concept designs for state-of-the-art technology power transfer subsystems including AC or DC power via cables, beamed radio frequency power and beamed laser power. Power transfer subsystem mass and performance are calculated and compared for each option. A simplified qualitative assessment of option operations, hazards, costs and technology needs is also described. Based on these concept designs and performance analyses, a DC power cabling subsystem is recommended to minimize subsystem mass and to minimize mission and programmatic costs and risks. Avenues for additional power transfer subsystem studies are recommended. Kerslake, Thomas W.

One of the biggest challenges of the exploration of the Moon is the survival of the crew and the lunar assets during periods of darkness (known as lunar night). The environmental conditions on the lunar surface and its cycle, with long periods of darkness, make any long mission in need of heat and electricity to be successful. This report presents two different systems to produce heat and electricity on the Moon's surface. The first system is composed by Thermal Wadis, sources of thermal power that can be used to supply heat to protect the exploration systems from the extreme cold during periods of darkness. Results show that Wadis can supply enough heat to keep the lunar electronic devices, such as lunar rovers, above their minimum operating temperature (approximately 243K). The second system developed and presented is the Thermal Energy Storage (TES) system, which is able to run a heat engine during the lunar night to produce electricity. When the sun is shining on the Moon's surface, the system can run the engine directly using the solar power and, at the same time, heat a thermal mass. This thermal mass will be used as a high temperature source to run the heat engine during periods of darkness. In order to choose every component for the TES system, we focused on both the production of the needed amount of energy and the minimization of the weight brought from the Earth to the Moon.
