Neil Armstrong was the first to physically stand on the moon. Followed by Buzz Aldrin.
Michael Collins piloted the "Columbia" alone in lunar orbit while Armstrong and Aldrin carried out the mission.
The two spent around two and a half hours on the moon collecting nearly 50 lbs of lunar material to bring back to Earth.
On July 16th, Apollo 11 was launched from the Kennedy Space Center in Merrit Island, Florida. This was NASA's fifth manned mission of the Apollo program.
The command module consisted of the three cabins for the three astronauts.
The Service module was the only piece that fell back to earth. It's job was to support the command module with propulsion, electrical power, water, and oxygen.
Finally, the Lunar Module. This had two parts, one to land on the moon, and one to launch them back into lunar orbit from the moon.
After being launched by Saturn V from the Kennedy Space Center, the astronauts separated from the rocket and drifted for three days until they finally reached the moon's orbit. They landed in "the Sea of Tranquility" on our moon.
