The world watched on tv as Neil Armstrong from Apollo 11 was the primary human to depart footsteps on the moon on July 20, 1969. It was the primary time people walked on one other world as he stepped onto the lunar floor, Armstrong stated: “That’s one small step for [a] man, one large leap for mankind.” Nonetheless picture by way of NASA video.
The Eagle has landed and footsteps on the moon
On July 20, 1969, Apollo 11 astronauts Buzz Aldrin and Neil Armstrong landed their moon module on a broad darkish lunar lava circulation, known as the Sea of Tranquility. And 6 hours later, Neil Armstrong turned the primary human being to stroll on the floor of a world past Earth.
Within the video under, you may hear the thrill in Armstrong’s voice on the profitable touchdown of Eagle on the moon’s floor as he says:
Tranquility Base right here. The Eagle has landed.

Altogether, Armstrong and Aldrin spent 21 1/2 hours on the moon’s floor. Moreover, they collected 47.5 kilos (21.5 kg) of moon rocks for return to Earth. After which they blasted off of their module from the lunar floor to satisfy up with Michael Collins within the command module orbiting overhead.
Lastly they returned safely to Earth and landed within the Pacific Ocean on July 24, 1969.
The Apollo 11 launch
Apollo 11 launched at 13:32:00 UTC (9:32:00 a.m. EDT native time) on July 16, 1969. Astronauts Neil A. Armstrong, Michael Collins and Edwin E. “Buzz” Aldrin, Jr., had been aboard. Picture by way of Wikipedia.Apollo 11 left Earth by way of a sort of rocket not longer in use, known as Saturn V. The enormous Saturn V rocket was 111 meters (363 ft) tall, in regards to the top of a 36-story-tall constructing. Read more about the Saturn V rocket. Picture by way of Wikimedia.Apollo 11 orbited Earth 1 1/2 instances. Twelve minutes after launch, it separated from the Saturn V rocket, as a propulsion maneuver despatched it on a path towards the moon. In the meantime here’s a view of Earth from Apollo 11, shortly after it left Earth orbit. Picture by way of Wikimedia.

The lunar module and Saturn V
Right here is the Apollo 11 lunar module, the automobile that will carry Neil Armstrong and Buzz Aldrin to the moon’s floor. It was known as “Eagle.” This picture additionally exhibits the module in its touchdown configuration, photographed in lunar orbit from the command module, which was known as “Columbia.” Astronaut Michael Collins, alone aboard Columbia, inspected Eagle because it pirouetted earlier than him to make sure the craft was not broken.

There at the moment are 2 heavy raise rockets, both of which might be used for moon missions. Read about SLS v Starship.
Issues in regards to the floor for footsteps on the moon
An early concern of space engineers had been that the lunar regolith, the superb soil masking the moon, could be tender like quicksand. There was some worry that the Eagle lunar module would sink after touchdown. Therefore Armstrong’s remark in regards to the depth of the footpads within the lunar soil as he descended the ladder earlier than stepping onto the moon.

This included deploying a U.S. flag, performing a number of science experiments, and gathering moon rocks. Nonetheless picture by way of NASA video.Right here is Buzz Aldrin, who piloted the lunar module Eagle to the moon’s floor, with the LR-3, a reflecting array designed to bounce laser beams fired from Earth again to Earth.

Splashdown and celebrations for a profitable return

A bounty of moon rocks introduced again to Earth
The Apollo astronauts introduced the first moon rocks again to Earth. Here’s a pattern.

Deborah Byrd created the EarthSky radio collection in 1991 and based EarthSky.org in 1994. Previous to that, she had labored for the College of Texas McDonald Observatory since 1976, and created and produced their Star Date radio collection. As we speak, she serves as Editor-in-Chief of this web site. She has received a galaxy of awards from the broadcasting and science communities, together with having an asteroid named 3505 Byrd in her honor. In 2020, she received the Training Prize from the American Astronomical Society, the most important group {of professional} astronomers in North America. A science communicator and educator since 1976, Byrd believes in science as a drive for good on this planet and a significant software for the twenty first century. “Being an EarthSky editor is like internet hosting an enormous world celebration for cool nature-lovers,” she says.
