Surveyor Lunar Lander

The artifact in the collection is an engineering model, S-10, used for thermal control tests. It was reconfigured to represent a flight model of Surveyor 3 or later, since it was the first to have a scoop and claw surface sampler. After receipt in 1968 it was displayed in Smithsonian's Arts & Industries Building and then was moved to its present location in Gallery 112, Lunar Exploration Vehicles, in 1976.

The Surveyor series was designed to carry out soft landings on the Moon and provide data about its surface and possible atmosphere. These were the first U.S. probes to soft-land on the Moon. Once landed they provided detailed pictures of the surface by means of a TV camera carried on each of the spacecraft. Later Surveyors carried the instrumented soil mechanics surface scoop seen on the artifact. These were used to study the mechanical properties of lunar soil. Some of the spacecraft were also equipped to perform simple chemical analyses on lunar soil by means of alpha particle scattering. There were seven Surveyor launches starting in May, 1966, all launched by the Atlas-Centaur rocket. All but two successfully achieved program goals returning over 88,000 high resolution photographs and invaluable detailed data on the nature and strength of the lunar surface.

Surveyor (1966-1968)

The Surveyor probes were the first U.S. spacecraft to land safely on the Moon. The main objectives of the Surveyors were to obtain close-up images of the lunar surface and to determine if the terrain was safe for manned landings. Each Surveyor was equipped with a television camera. In addition, Surveyors 3 and 7 each carried a soil mechanics surface sampler scoop which dug trenches and was used for soil mechanics tests and Surveyors 5, 6, and 7 had magnets attached to the footpads and an alpha scattering instrument for chemical analysis of the lunar material. The following Surveyor missions took place.
