Lunar Lander, Surveyor, Crushable Blocks

These are back-up aluminum honey-combed crushable landing pads that rested at the end of three shock-absorber legs attached to the frame of the Surveyor spacecraft, which went to the Moon in the 1960s. Although not flown to the Moon, they are identical to those on the five Surveyor soft-landing spacecraft that successfully reached the Moon during the period from May 30, 1966 to January 9, 1968. The overall objectives of the Surveyor program were to accomplish soft landings on the Moon, obtain data concerning temperature, chemical composition, and load-bearing characteristics of the lunar soil in support of the Apollo program, televise high quality photographs of the lunar surface, and perform operations on the lunar surface that would contribute new scientific knowledge about the Moon.

The Hughes Aircraft Company donated these to the Museum in 1973.

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.
