Astronaut Buzz Aldrin on the moon

In this photo, you are able to see NASA astronaut Buzz Aldrin, the lunar module pilot, standing on the Moon's surface near the lunar module Eagle's landing gear during a moonwalk on the Apollo 11 mission.
Apollo 11 was a U.S. spaceflight mission, operated by NASA, that took place from July 16 through July 24, 1969, and that successfully made the first manned landing on the Moon.
Astronaut Neil Armstrong, first person to walk on the Moon and mission commander, snapped this photo using a 70mm lunar camera.
If you look at the photo very closely, you can observe reflections of Neil Armstrong, Earth, the lunar module, the flag planted, and scientific equipment in Aldrin's helmet visor.
It was on this historic journey that Neil Armstrong uttered his eternal line: "That's one small step for [a] man, one giant leap for mankind."
Besides Neil Armstrong and Buzz Aldrin, the third member of the crew was Michael Collins - the command module pilot. Collins did not go to the Moon's surface but remained in lunar orbit on board the main spacecraft, piloting and maintaining continuous contact with the Earth.
