Apollo 11 was the spaceflight that landed the first two people on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin, both American, landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC.

Apollo 11 Moon Landing - Buzz Aldrin on the Moon

Moon Landing: Astronaut Buzz Aldrin, lunar module pilot, stands on the surface of the moon near the leg of the lunar module, Eagle, during the Apollo 11 moonwalk. Astronaut Neil Armstrong, mission commander, took this photograph with a 70mm lunar surface camera. While Armstrong and Aldrin descended in the lunar module to explore the Sea of Tranquility, astronaut Michael Collins, command module pilot, remained in lunar orbit with the Command and Service Module, Columbia.
This is the actual photograph as exposed on the moon by Armstrong. He held the camera slightly rotated so that the camera frame did not include the top of Aldrin’s portable life support system (“backpack”). A communications antenna mounted on top of the backpack is also cut off in this picture. When the image was released to the public, it was rotated clockwise to restore the astronaut to vertical for a more harmonious composition, and a black area was added above his head to recreate the missing black lunar “sky”. The edited version is the one most commonly reproduced and known to the public, but the original version, above, is the authentic exposure.
This image was cataloged by NASA Headquarters of the United States National Aeronautics and Space Administration (NASA) under Photo ID: AS11-40-5903.

Apollo 11 launched from Cape Kennedy on July 16, 1969, carrying Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin “Buzz” Aldrin.

On July 18, Armstrong and Aldrin put on their spacesuits and climbed through the docking tunnel from Columbia to Eagle to check out the Lunar Module (LM).

On July 20, Armstrong and Aldrin entered the LM again, made a final check, and at 100 hours, 12 minutes into the flight, the Eagle undocked and separated from Columbia for visual inspection.

On July 20, 1969, at 20:17 UTC, partially piloted manually by Armstrong, the Eagle landed in the Sea of Tranquility in Site 2 at 0 degrees, 41 minutes, 15 seconds north latitude and 23 degrees, 26 minutes east longitude. This was about four miles downrange from the predicted touchdown point and occurred almost one-and-a-half minutes earlier than scheduled. It included a powered descent that ran a mere nominal 40 seconds longer than preflight planning due to translation maneuvers to avoid a crater during the final phase of landing.


Margaret Hamilton – her code got humans on the moon

Margaret Hamilton is not only one of the first software developers, but she also literally created the term “Software Engineering” to describe her work. The code she wrote successfully put humans on the moon for the first time.

For All Moonkind – Messages of Peace

Apollo 11 astronauts Neil Armstrong and Buzz Aldrin were the first people to walk on the moon. After more than ​21 12 hours on the lunar surface, in addition to the scientific instruments, they left behind an Apollo 1 mission patch and a memorial bag containing a gold replica of an olive branch as a traditional symbol of peace and a silicon message disk.

Saturn V Rocket (Documentary)

A documentation about the Saturn V, the biggest and most powerful rocket ever built (as of 2019, it still holds these titles). The three-stage liquid-fueled super heavy-lift launch vehicle was used
by NASA between 1967 and 1973. Saturn V was developed to support the Apollo program for the Moon landing and was later used to launch Skylab.

Watch: Nvidia Debunks Conspiracy Theories About Moon Landing

A spokesperson from Nvidia, the American technology company specialized in manufacturing high-performance graphics processing units (GPUs), debunks the conspiracy theories about the moon landing. The tech giant uses the latest technology to recreate some of the iconic photos which taken during the moon landing digitally and to debunk conspiracy theories around them.

Watch: Neil Armstrong’s Parents at I’ve Got a Secret

On September 17, 1962, Neil Armstrong’s parents, Stephen Koenig Armstrong and Viola Louise Engel Armstrong joined “I’ve Got a Secret”, a panel game show produced by Mark Goodson and Bill Todman for CBS television. They had a “secret” that their son just became an astronaut for NASA on that day, one of the nine newly chosen men for the future space missions.

Mr. and Mrs. Armstrong whispers the Host Garry Moore’s ears their secret: “Our Son became an astronaut today”.

A few minutes later, Moore asks an incredible question: “Now, how would you feel, Mrs. Armstrong, if it turned out – of course, nobody knows – but if it turns out that your son is the first man to land on the moon? What, how do, how would you feel?” He asks this nearly seven years before it actually happens on July 20, 1969! Neil’s mother’s reply is priceless, “Well, guess I’d just say god bless him and I wish him the best of all good luck.”

Watch: Apollo 11’s journey to the moon, annotated

On July 20, 1969, at 20:17 UTC, two American astronauts, Apollo 11 mission commander Neil Armstrong and pilot Buzz Aldrin landed the lunar module Eagle on the Moon. It was the first time humans set foot on another planetary body than Earth, making the moon landing probably the most monumental event in history.

Vox.com published a beautiful video highlighting the key moments of the Apollo 11 mission.

Life on the Moon? New study suggests there was a habitability window 4 billion years ago

The Moon is completely uninhabitable and lifeless today – a dusty, dry rock. It has no atmosphere, there is no liquid water on the surface, and, maybe the most important, it has no magnetosphere to protect its surface from solar wind and cosmic radiation. But, according to a new study published in Astrobiology, it may have looked quite different around four billion years ago: its surface was not as dry as it is today, and conditions to support simple life on the Moon existed twice during the early years.

NASA Has Released Apollo 11 Mission Audio

NASA has just published Two Years’ Worth of Apollo 11 Mission Audio (the first manned moon landing mission) on their website “Explore Apollo“. That’s more than 19,000 hours of audio.

So now anyone can hear the endless hours of conversations between the Apollo 11 astronauts and Houston. Some recordings are really exciting, for example, the audio of the lunar module landing. When the lunar module enters the lunar orbit some interesting, tensed and nail-biting technical challenges are encountered and are solved.

Why can’t we Remake the Rocketdyne F-1 Engine, which took humans to the Moon?

The mighty Saturn V, the rocket that took humans to the moon, remains the tallest, heaviest, and most powerful rocket ever brought to operational status (as of 2018). It was used by NASA between 1967 and 1973. It was powered by five Rocketdyne F-1 engines. With a thrust of 1,746,000 lbf (7,770 kN) in vacuum (1,522,000 lbf / 6,770 kN at sea level), the F-1 remains the most powerful single combustion chamber liquid-propellant rocket engine ever developed.

Today, private companies like SpaceX, Blue Origin, and space agencies like NASA trying to build powerful rockets in order to reach Moon and Mars. But, we’ve already built a rocket which took us to the moon, why don’t we simply remake it (and the engines)? In the video below, Youtube user Curious Droid answers this question.

I was on the Moon!

On July 20, 2018 (on the 49th anniversary of the moon landing), Linn LeBlanc, Chief Operating Officer at Buzz Aldrin Ventures, LLC asked on Twitter that: “Where were you 49 years today when @TheRealBuzz and Neil Armstrong made those historic first steps onto the Moon. Congratulations to the #Apollo11 crew and to the thousands that made those steps possible!” And Buzz Aldrin’s answer to that question was brilliant: “I was on the Moon!”
