J-2 Rocket Engine
The J-2 rocket engine was developed to power the S-II and S-IV stages of the
Saturn V vehicle.
The J-2 development program began in 1960 with the first manned flight in 1968.
The 152-engine production program was completed in 1970.
A major highlight of the engines' successful flight record came in July 1969.
The J-2 engines powered stages of the Saturn V AS-506 for Earth-to-orbit and
the translunar flight portions of Apollo 11, the first manned lunar
landing mission with astronauts Neil Armstrong, Edwin Aldrin, and Michael
Collins. Armstrong and Aldrin stepped on the Moon July 20, 1969.
