President John F. Kennedy decided to send an American astronaut to the moon and NASA wanted to expand this opportunity at Cape Canaveral and build a spaceport for manned lunar launches. During this era, NASA activated its Launch Operations Center, today known as Kennedy Space Center, granting the lunar launch site equal status with other agency field centers.
Soon, the construction of the Vehicle Assembly Building came into being. On 9 Nov 1967, an unmanned Saturn B blasts off on the first test flight of the rocket that launched moon-bound American astronauts. It was the first exclusive launch from John F. Kennedy Space Center.
American astronauts Jim Lovell, William Anders, and Frank Borman blast off from launch pad 39A on the Apollo 8 mission. It was the first manned launch of a Saturn V rocket, the first manned launch from the famous Kennedy Space Center.
