Today marks the pivotal moment the Apollo 11 mission blasted off from Earth 50 years ago to land on the moon just four days later.
This monumental move put astronaut Neil Armstrong firmly on the map in history as he became the first person to ever walk on the moon.
On Saturday, July 20, events will take place across the world to commemorate the team who took part in NASA's pioneering 225,623-mile journey.
On the mission, Armstrong was joined by American astronaut Michael Collins and lunar module pilot Edwin "Buzz" Aldrin - who was the second pilot to walk on the surface, just 20 minutes after Armstrong.
With lots of talk about the Apollo 11's 50th anniversary, let's get to know the main man himself. Here's everything you need to know about Neil Armstrong.
When was Neil Armstrong born?
Armstrong was born in Wapakoneta, Ohio, on August 5 in 1930.
How did his career start?
He studied aeronautical engineering at university, with his tuition paid for by the U.S Navy under the Holloway Plan.
Armstrong went on to join the Navy, as first a midshipman then a naval aviator. He partook in the Korean War, flying one of the US Navy's first successful carrier-based fighter jets - the Grumman F9F Panther.
Post war, Armstrong completed a bachelor's degree to become a test pilot at NASA's high speed flight station in California. He was selected as an astronaut in 1962.
He fulfilled various roles within the space agency before making his first spaceflight as a command pilot in March 1966, becoming NASA's first civilian astronaut to fly in space.
Three years later he embarked on the historic Apollo 11 mission as commander.
What were his first words on the moon?
The iconic words that still ring in people's ears today after all of those years:
"That's one small step for [a] man, one giant leap for mankind."
When did he resign?
Armstrong resigned from NASA in 1971 and began to teach in the department for Aerospace Engineering at the University of Cincinnati up until 1979.
He then served on the Apollo 13 accident investigation - this was the seventh crewed mission in the space programme, which was aborted after an oxygen tank exploded two days after launching.
What was his family-life like?
Armstrong met his first wife Janet Elizabeth Shearon whilst at university.
The couple married in January 1956, but separated in 1990.
They had three children together - Eric, Karen and Mark. Sadly daughter Karen was diagnosed with a brain tumour and died of pneumonia in 1962 at the age of just two.
Armstrong met his second wife Carol Held Knight in 1992 and were married by 1994.
When did Armstrong die?
Armstrong died on August 25, 2012, aged 82.
He underwent a heart bypass operation and died a few weeks later from complications resulting from the procedure.
Shortly after his death, his family released a statement: "For those who may ask what they can do to honor Neil, we have a simple request. Honor his example of service, accomplishment and modesty, and the next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink."
