Apollo 8 [SEP] Introduction
Apollo 8 was the first crewed spacecraft to leave low Earth orbit and the first to reach the Moon, orbit it, and return. Its three-astronaut crew — Frank Borman, James Lovell, and William Anders — were the first humans to fly to the Moon, to witness and photograph an Earthrise, and to escape the gravity of a celestial body. Apollo 8 launched on December 21, 1968, and was the second crewed spaceflight mission flown in the United States Apollo space program after Apollo7, which stayed in Earth orbit. Apollo8 was the third flight and the first crewed launch of the Saturn V rocket, and was the first human spaceflight from the Kennedy Space Center, located adjacent to Cape Canaveral Air Force Station in Florida.
