Project Mercury was the first time a human has gone into outer space.It was evoked by the Russians sending Sputnik 1,the first Sattilite, into space.It included astronauts Alan Shepard,Gus Grissom,and Jon Glenn.
Project Gemini's objective was to see if more than 1 human could go into space in the same craft at the same time.It was the 2nd of 3 projects on going to the moon.
Project Apollo was the project leading up to landing on the moon.Neil Armstrong,Buzz Aldrin,and Michael Collins were the astronauts that went to the moon.
My favorite scene was when Apollo 11 came home safely ,it was good to see the U.S. Beat their challenge.
