How many astronauts were aboard Apollo 11 as it took off for the historic moon landing mission?

On July 16, 1969, Apollo 11 took off from Kennedy Space Center at 9:32 a.m. EDT. Three astronauts were aboard the spacecraft as it departed for its historic mission; they were Neil Armstrong, Buzz Aldrin, and Michael Collins.

After reaching the lunar orbit on July 19, the lunar module Eagle detached from the command module and made its way to the surface of the moon. Armstrong and Aldrin were aboard Eagle while Collins remained in the command module.

After reaching the moon’s surface, Armstrong was the first to step foot on it, after which he uttered his famous quote. 19 minutes later, he was joined by Aldrin.
