The '''Surveyor program''' was a [[NASA]] program that, from June 1966 through January 1968, sent seven [[robotic spacecraft]] to the surface of the [[Moon]]. Its primary goal was to demonstrate the feasibility of [[Soft landing (rocketry)|soft landings]] on the Moon. The Surveyor craft were the first American spacecraft to achieve soft landing on an [[Astronomical object|extraterrestrial body]]. The missions called for the craft to travel directly to the Moon on an impact trajectory, a journey that lasted 63 to 65 hours, and ended with a deceleration of just over three minutes to a soft landing.<ref name=Kloman1972/>
