Soil Mechanics

NSSDCA ID: 1969-099C-10

Mission Name: Apollo 12 Lunar Module / ALSEP
Principal Investigator:Prof. James K. Mitchell

Description

The purpose of this expeirment was to determine the mechanical properties of the lunar surface at the landing site in Oceanus Procellarum, at the site of Surveyor III. These properties were measured by the cohesion, porosity, particle size, density, coefficient of friction, packing characteristics, and friction angle of the soil or surface material. Data were obtained from real-time observations of TV, photographs, spacecraft behavior telemetry at landing, and experiments on returned soil samples.
