In this July 20, 1969 photo made available by NASA, astronaut Buzz Aldrin Jr. poses for a photograph beside the U.S. flag on the moon during the Apollo 11 mission. Aldrin and fellow astronaut Neil Armstrong were the first men to walk on the lunar surface with temperatures ranging from 243 degrees ab

Celebrate Space Exploration Day by looking up at the sky on July 20 and reflecting on human achievements in space and all that’s to come.

On July 20, 1969, U.S. astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon’s surface. Fellow astronaut Michael Collins flew the command module.

Here is a look back at the first moon landing:

“That’s one small step for man, one giant leap for mankind,” said astronaut Neil Armstrong as he became the first human to set foot on the moon, as shown in the image from television. (NASA/AP Photo)
