The Surveyor probes were the first U.S. spacecraft to land safely on the Moon. The images above show the Surveyor spacecraft at the beach and a view of the footpad of Surveyor 5. The trench to the right of the footpad was formed during the landing. 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 image on the upper right shows the Surveyor 5 footpad.
