Neil Armstrong flew to the moon on the Apollo 11 mission. The spacecraft consisted of three parts:

* Command Module (Columbia): This was the main part of the spacecraft, where the astronauts lived and flew back to Earth.

* Service Module: Attached to the Command Module, it provided propulsion, power, and life support.

* Lunar Module (Eagle): This was the landing craft that carried Armstrong and Buzz Aldrin to the moon's surface.

So while the Apollo 11 was the overall mission, the specific spacecraft Neil Armstrong rode in to land on the moon was the Lunar Module, called "Eagle."
