Its mission including taking TV pictures after landing, determine relative chemical element abundance and manipulate the lunar material. It was the only Surveyor craft of the series to land in a lunar highland region. In addition to touchdown dynamics data, it obtained thermal and radar reflectivity data. The spacecraft was about 3-m tall. A solar cell array produced up to 85-watts of electrical power, stored in batteries and used for communications.
