The deployment of the flag of the United States on the surface of the Moon is captured on film during the first Apollo 11 lunar landing mission. Here, astronaut Neil A. Armstrong, commander, stands on the left at the flag's staff. Astronaut Edwin E. Aldrin, Jr., lunar module pilot, is also pictured. The picture was taken from film exposed by the 16mm Data Acquisition Camera (DAC) which was mounted in the Lunar Module (LM). While astronauts Armstrong and Aldrin descended in the Lunar Module (LM) "Eagle" to explore the Sea of Tranquility region of the Moon, astronaut Michael Collins, command module pilot, remained with the Command and Service Modules (CSM) "Columbia" in lunar-orbit.
