Rocket Engine, Liquid Fuel, J-2, Mockup
This mockup of a J-2 liquid propellant rocket engine, powered by liquid hydrogen and liquid oxygen, is representative of the power plant used on the second and third stages of the Saturn V launch vehicle that took astronauts to the Moon in the Apollo program. The J-2 produced a thrust of 200,000-230,000 pounds. The Saturn V's second (S-II) stage used a cluster of five J-2's, while the third (S-IVB) stage was fitted with a single J-2 . The first manned flight with the J-2 engine was made on October 11, 1968 in the Saturn 1B Apollo 7 test mission. The Rocketdyne Division of Rockwell International donated this J-2 engine mockup to the Smithsonian in 1976.
