It was 1961. John F. Kennedy was the president of the United States. He wanted to land humans on the moon. The United States had just started trying to put people in space. Was NASA ready to go to the moon? The president and NASA knew they could do it. They were ready to put people on the moon. Apollo 11's mission was to land two men on the moon. They also had to come back to Earth safely. Apollo 11 blasted off on July 16, 1969. Neil Armstrong, Edwin Buzz Aldrin and Michael Collins were the astronauts on Apollo 11. Four days later, Armstrong and Aldrin landed on the moon. They landed on the moon in the Lunar Module. It was called the Eagle. Collins stayed in orbit around the moon. He did experiments and took pictures. The sign the astronauts left on the moon says, Here men from the planet Earth first set foot upon the moon July 1969, A.D. We came in peace for all mankind.
