The mission of Surveyor 7 was to explore a region of the Moon other than lunar maria and into the lunar highlands. Surveyor 7 was the first probe to detecet the faint glow on the lunar horizon after dark that is now thought to be light reflected from electrostatically levitated

The mission of Surveyor 6 was to demonstrate the technology necessary to achieve landing and operations on the lunar surface. Before termination of operations, on Nov. 17, 1967, Surveyor 6 was commanded to fire its three main liquid propellant thrusters for 2.5 seconds.

The mission of Surveyor 5 was to demonstrate the technology necessary to achieve landing and operations on the lunar surface. Surveyor 5 was the first human spacecraft to complete a soil analysis on another celestial boday other than Earth.

The mission of Surveyor 4 was to demonstrate the technology necessary to achieve landing and operations on the lunar surface. Radio signals from the spacecraft stopped a few minutes before landing and contact was never reestablished.

Surveyor 3 was designed to achieve a soft landing on the lunar surface and to return lunar surface photography and other data. Astronauts from Apollo 12 made contact with Surveyor 3 and recovered parts to return to Earth so that scientists could evaluate the effects of nearly two-and-a-half years of

The mission of Surveyor 1 was to demonstrate the technology necessary to achieve landing and operations on the lunar surface. Surveyor 1 collected information about the lunar surface that informed the planning for the Apollo crewed lunar landings.
