Surveyor 5 was launched on 8 September 1967 and landed in Mare Tranquillitatis on 11 September 1967. The mission's objectives were to soft land on the Moon and collect information on the properties of the lunar regolith to prepare for the upcoming Apollo missions. Surveyor 5 carried a television camera (ultimately returning 19,118 images) and an alpha particle backscattering instrument to measure the composition of the lunar regolith in-situ.
