Developed at MSFC under the direction of Dr. Wernher von Braun, the SA-5 incorporated a Saturn I, Block II engine. Launched on January 29, 1964, SA-5 was the first two stage (Block II) Saturn with orbital capability and performed the first test of Instrument Unit and successful stage separation. Block II vehicles had two live stages, and were basically in the two-stage configuration of the Saturn I vehicle. There were marked changes between the Block I and II versions. The Block II S-I stage had eight fins added for greater aerodynamic stability in the lower atmosphere. All Block II H-1 engines had a thrust of 188,000 pounds each for a combined thrust over 1,500,000 pounds. The Block II second stage (S-IV) had six RL-10 hydrogen-oxygen engines, each producing a thrust of 15,000 pounds for a total combined thrust of 90,000 pounds. A motion picture camera capsule loated on stage I was successful recovered.
