On This Day - June 2nd 1966
The US "Surveyor I" spacecraft successfully lands on the moon.
Surveyor 1 was the first lunar lander in the American Surveyor program that explored the Moon. The program was managed by the NASA Jet Propulsion Laboratory. Launched on 30 May 1966, the US Spacecraft Surveyor I made the first successful soft landing on the moon on 2 June 1966, in the "Ocean of Storms". The spacecraft carried two television cameras: one for approach, which was not used, and one for operations on the lunar surface, which enabled it to take clear pictures of the depth of the depression in the lunar soil made by its footpad when it soft-landed, and of the surrounding lunar terrain and surface materials.
Equipment also included 100 engineering sensors. The spacecraft also acquired data on the radar reflectivity of the lunar surface, bearing strength of the lunar surface, and spacecraft temperatures for use in the analysis of the lunar surface temperatures. Data continued to be transmitted back to Earth from shortly after touchdown until 14 July 1966, although commands were issued for no operation during the lunar night, from 14 June to 7 July 1966.
