On 16 July 1969, American astronauts Neil Armstrong, Edwin "Buzz" Aldrin, and Michael Collins lifted off from Cape Canaveral, Fla., in the mammoth-sized Saturn V rocket on their way to the moon during the Apollo 11 mission. Cmdr. Armstrong and pilot Aldrin landed the spacecraft, Eagle, on the moon's Sea of Tranquillity. Apollo 11 booster stages were tested at Stennis Space Center.
