About two hours after leaving Earth the passenger module departed the main rocket. The passenger module had two main parts, the Apollo command and service module called "Columbia" and the Apollo Lunar Module called "Eagle". "Columbia" was the space ship that stayed in space, and "Eagle" was the moon-landing space ship. 3 days later the team entered Lunar Orbit (orbit around the moon). A day later the "Eagle" went away from "Columbia". The "Eagle" landed safely on the moon with Neil Armstrong and Buzz Aldrin inside. During the landing, there were several problems with the computer. To land safely Armstrong had to fly the "Eagle" himself. They landed with only 25 seconds of fuel left.
