The Apollo 9 spacecraft had two vehicles. One was the command module. It could orbit the moon, but could not land on it. The other was the Lunar module. On a flight to the moon, it would separate from the command module and land on the moon's surface. Apollo 10 astronauts unlinked the Lunar module and flew it close to the moon's surface.
After those flights, everything was ready.
NASA ANNOUNCER: "Twelve, eleven, ten, nine … ignition sequence start … six, five, four, three, two, one, zero. All engines running. Lift-off. We have a lift-off. Thirty-two minutes past the hour. Lift-off of Apollo 11."
On July sixteenth, nineteen sixty-nine, three American astronauts lifted off in Apollo 11. On the twentieth, Neil Armstrong and Edwin Aldrin entered the Lunar module, called the Eagle. Michael Collins remained in the command module, the Columbia.
The two vehicles separated.
It was a dangerous time. The Eagle could crash. Or it could fall over after it landed. That meant the astronauts would die on the moon.
Millions of people watched on television or listened on the radio. They waited for Armstrong's message.
NEIL ARMSTRONG: "Houston, Tranquility Base here. The Eagle has landed."
"The Eagle has landed." Then they waited again. It took the astronauts more than three hours to complete the preparations needed to leave the Lunar module.
Finally, the door opened. Neil Armstrong climbed down first. He put one foot on the moon. Then, the other foot. And then came his words, from so far away:
