The first Hughes A-21 class spacecraft, Surveyor SC1 (NASA designation Surveyor A), was launched at 1441:01 1966 May 30 by Atlas Centaur AC-10 from LC36 at Cape Kennedy. The Centaur 1D, with model RL10A3CM-1 engines, made a single burn and cutoff at 1452:30 delivering Surveyor I to translunar trajectory. The probe made a course correction at 0645 on May 31 and began its descent to the Moon on Jun 2. The radar was ejected at 0614 and the Star 37 solid motor fired. The retro was jettisoned at 0617 and Surveyor I made the first fully controlled soft landing on Luna at 0617:34. It transmitted data from the lunar surface until 0730 on 1967 Jan 7.
Launch azimuth was 102.3 deg.
Landing was at 43.23W 2.46S.
