American astronaut Neil Armstrong made history 49-years-ago as the first human to step onto the surface of the moon.
Every year on July 20 NASA celebrates the monumental achievement from 1969.
Today, NASA has shared some of the most detailed and beautiful photos of the lunar landing taken by its three astronauts Neil Armstrong, Michael Collins and Buzz Aldrin.
The photographs make up the Project Apollo Archive and have been seen more than one billion times since September 2015.
The Project Apollo Archive itself dates back to February 1999 when it was created by NASA network administrator Kipp Teague.
Mr Teague has since share beautiful high-resolution scans of the negatives taken by the Apollo astronauts.
The lunar pictures were taken on classic medium-format Hasselblad film cameras, providing crisp and detailed insight into the monumental Apollo 11 mission.
The detail in the pictures is such that you can zoom in on the astronauts reflected in each others’ visors.
The NASA photos document all aspects of the lunar landing mission from the surface of the moon to the more intimate moments inside the lunar lander.
Included in the images are snapshots of the astronauts’ footprints left behind on the moon.
Other pictures show the American astronauts planting the US flag and hopping around in the low gravity environment.
One photo shows the eclipsed night-time face of the Earth peaking over the lunar horizon, some 238,855 miles away.
On May 25, 1961 the late US President John F Kennedy vowed to put an American on the surface of the moon by the end of the decade.
In a televised speech to Congress the President said: “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to Earth.”
His dream came to fruition after nearly 10 gruelling years when Mr Armstrong stepped out of the lunar lander at exactly 2.56am UK time, July 21.
The pinnacle of the lunar landing was the historic quote uttered by the astronaut as he stepped out onto the alien world.
Broadcast live across the United States from the Moon, he said: “That’s one small step for a man, one giant leap for mankind.
“Mystery creates wonder and wonder is the basis of man’s desire to understand.
“Houston, Tranquillity Base here. The Eagle has landed.”
