AbstractThe exploration and development of space will require energy that is reliable, ubiquitous, and economical to produce. The international space station relies on photovoltaics to generate electricity stored in nickel-hydrogen batteries for powering the station during the “night”.

Lunar Soil Sampling and Testing
1962The limited real data available on the lunar environment is presented and several selected references are listed. Soil is usually tested for the properties that are expected to change and differ from one environment to another, whereas the properties that are more or less in equilibrium in any terrestrial environment are not tested.

The great research effort that has been mobilized to attempt solution of lunar exploration problems involving properties of soils and rocks on the Moon is summarized and reviewed. Current (1963) research activity has been examined within the framework of five categories: (1) Exploration and mapping of the lunar surface; (2) lunar soil formation and the

Bearing strength of lunar soil
The Moon, 1971Bearing load vs penetration curves have been measured on a 1.3 g sample of lunar soil from the scoop of the Surveyor 3 soil mechanics surface sampler, using a circular indentor 2 mm in diameter. Measurements were made in an Earth laboratory, in air.
