    Apollo 11 (July 16–24, 1969) was the American spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin landed the Apollo Lunar Module on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin .

    Apollo 11 was launched by a Saturn V rocket from Kennedy Space Center on Merritt Island, Florida, on July 16 at 13:32 UTC, and it was the fifth crewed mission of NASA's Apollo program. The Apollo spacecraft had three parts: a command module (CM) with a cabin for the three astronauts, the only part that returned to Earth; a service module (SM), which supported the command module with propulsion, electrical power, oxygen, and water; and a lunar module (LM) that had two stages—a descent stage for landing on the Moon and an ascent stage to place the astronauts back into lunar orbit.

    After being sent to the Moon by the Saturn V's third stage, the astronauts separated the spacecraft from it and traveled for three days until they entered lunar orbit. Armstrong and Aldrin then moved into and landed in the Sea of Tranquility on July 20. The astronauts used 's ascent stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned before they performed the maneuvers that propelled out of the last of its 30 lunar orbits onto a trajectory back to Earth.[9] They returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space.

    Who Has Walked on the Moon?

    Neil Armstrong and Edwin "Buzz" Aldrin were the first of 12 human beings to walk on the Moon. Four of America's moonwalkers are still alive: Aldrin (Apollo 11), David Scott (Apollo 15), Charles Duke (Apollo 16), and Harrison Schmitt (Apollo 17).

    In all, 24 American astronauts made the trip from Earth to the Moon between 1968 and 1972. Three astronauts made the journey from Earth to the Moon twice: James Lovell (Apollo 8 and Apollo 13), John Young (Apollo 10 and Apollo 16), and Gene Cernan (Apollo 10 and Apollo 17).

    53rd anniversary of US putting 1st man on the moon

    53rd anniversary of US putting 1st man on the moon

    'People will never look at the sky the same way again,' says Brian Odom, NASA's acting chief historian

    Darren Lyn   | 20.07.2022

    HOUSTON, Texas​​​​​​​

    For all eternity, the US will lay claim to being the first country to put a man on the moon.

    Fifty-three years ago, on July 20, 1969, NASA spacecraft Apollo 11 landed on the moon with astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins aboard.

    All three became iconic figures around the world, with Armstrong becoming the first human to set foot on the moon's surface.

    "That's one small step for man, one giant leap for mankind," he exclaimed on that glorious day.

    "Obviously, firsts are usually the ones we remember the most, and Neil’s accomplishment certainly ranks among the most notable firsts of all time," said Brian Odom, the US space agency’s acting chief historian. "His calm, cool demeanor during the mission also became legendary and made him the subject of many documentaries, films, and stories."

    "The reaction to Apollo 11 was tremendous both in the US and internationally," Odom told Anadolu Agency. "Once the astronauts returned home, they became instant celebrities, as the landing was understood to be one of the greatest of humanity's accomplishments."

    Space Race

    The triumph of that historic day was the result of the US battling the Soviet Union during the 20th century in what became known as the Space Race.

    "In May 1961, President John F. Kennedy committed the US to the Moon program. The decision followed a series of notable firsts for the Soviets, including Sputnik in 1957 and Yuri Gagarin’s orbital flight in April 1961," Odom explained.

    "At the time, the Cold War magnified these defeats, as communism and democracy were locked in what appeared to many to be an existential battle around the world."

    This competition between the two global giants propelled both countries to press forward with the Space Race with the goal of letting the world know which nation was number one. That meant countless resources being poured into NASA's space program.

    "Kennedy believed technological achievements were important to the Cold War race but also that the investment in the Apollo program would have implications back home in terms of national capabilities in research and development," said Odom. "Kennedy believed this investment would also have implications on the American economy and society. The success of Apollo 11 in 1969 was the culmination of that process."

    That first mission to the moon intensified America's focus on the space program and immediately impacted the scientific community worldwide.

    Shuttle, Hubble, Mars Rover

    "More missions returned to the lunar surface, expanding science and exploration," Odom explained. "These accomplishments allowed the US and international partners to build upon that success by returning to low Earth orbit to understand the microgravity environment, planetary science, astrophysics, and Earth science."

    Less than three years after the US put the first person on the moon, President Richard Nixon declared in 1972 that NASA would develop a space transportation system featuring a vehicle capable of shuttling "repeatedly from Earth to orbit and back."

    Then, on April 12, 1981, another nine years later, the first space shuttle, Columbia, blasted off, beginning a 30-year run of 135 shuttle missions, which carried more than 350 crew members into outer space, traveling more than 804 million kilometers (500 million miles) during that period.

    "Following Apollo, NASA dedicated its human spaceflight efforts to the space shuttle," said Odom, praising its ability to “allow us to learn valuable lessons in low-Earth orbit and to live and work in space."

    Exploring the vast unknowns of space did not end there. From the space shuttle program to the Hubble Space Telescope to the Mars Rover, the first moon landing has been an important catalyst in America's commitment to space exploration more than a half-century later.

    Webb Telescope, return to the Moon, and manned Mars mission

    "The moon landing continues to inspire NASA and its workforce, commercial and international partners to dream big," emphasized Odom. "One important example is the recent success of the James Webb Space Telescope. This telescope is the largest and most complex space science observatory ever built to transform our view of the universe and deliver world-class science."

    "Like Apollo before it, Webb is one of the great engineering feats of humanity," Odom stressed. "The recently revealed first images brought us together to wonder at our shared cosmic origins."

    Over the decades since the first moon landing, many space enthusiasts have wondered when the US will send another crew of astronauts to the moon.

    Wonder no more.

    "NASA is going back to the Moon and beyond with the Artemis Program," said Odom. "With Artemis, NASA will land the first woman and first person of color on the Moon, using innovative technologies to explore more of the lunar surface than ever before for the benefit of all."

    NASA continues to test the Artemis human landing system and its next-generation spacesuits, with a target date for that first mission sometime in 2026.
