The History of Moon Landing: From Dreams to the Lunar Surface

On July 20, 1969, humanity witnessed a moment they had dreamed of for thousands of years while gazing up at the night sky. As American astronaut Neil Armstrong took his first step onto the lunar surface, he uttered the famous words: “That’s one small step for man, one giant leap for mankind.”^[1] However, the journey to this remarkable moment was the result of centuries of scientific discovery, technological challenges, and international competition.

1. Humanity’s Dream of the Moon

Ancient Lunar Observation

Humanity has been fascinated by the Moon since time immemorial. Ancient civilizations observed the lunar cycles to create calendars and worshipped the Moon through myths and legends. However, actually traveling to the Moon was nothing more than an impossible fantasy.

Jules Verne and Early Science Fiction

In 1865, French author Jules Verne published the novel “From the Earth to the Moon.” Remarkably, Verne wrote about sending three people to the Moon via a cannon launched from Florida, which seemed to foreshadow the Apollo program that would actually occur about 100 years later.^[2]

2. The Birth of Rocket Science: The Pioneers

Konstantin Tsiolkovsky (1857-1935)

Russian mathematics teacher Konstantin Tsiolkovsky laid the theoretical foundation for space travel. In 1903, he published “Exploration of Outer Space by Means of Reaction Motors,” presenting the concept of liquid-fuel rockets. The Tsiolkovsky rocket equation he developed is still used as the basis of rocket science today.^[3]

Tsiolkovsky was the first to propose the principle of multi-stage rockets and came up with the idea of using liquid hydrogen and liquid oxygen as propellants. Although he never had the opportunity to test his theories during his lifetime, he left behind the famous quote: “Earth is the cradle of humanity, but one cannot live in a cradle forever.”^[3]

Robert Goddard (1882-1945)

American physicist Robert Hutchings Goddard was the man who turned theory into practice. On March 16, 1926, he successfully launched the world’s first liquid-fuel rocket in Massachusetts. The rocket flew for only 2.5 seconds and reached a height of 12.5 meters, but this was a historic moment marking the beginning of humanity’s space exploration.^[4]

Goddard received 214 patents during his lifetime and succeeded in flying a rocket at 885 kilometers per hour in 1935. However, he did not receive sufficient recognition during his life, and The New York Times even published an article mocking his research in 1920. The Times apologized to Goddard only 49 years later, one day before the Apollo 11 launch in 1969.^[4]

Wernher von Braun (1912-1977)

German rocket engineer Wernher von Braun is a figure with a complex history. He developed the V-2 rocket for Nazi Germany during World War II, which was used to attack London and other cities.^[5]

After the war ended, von Braun and his team immigrated to the United States and joined the American space program as part of Operation Paperclip. He later became the director of NASA’s Marshall Space Flight Center and led the development of the Saturn V rocket, the centerpiece of the Apollo program.^[5]

3. The Space Race: The Cold War’s Celestial Battlefield

Sputnik Shock (1957)

On October 4, 1957, the Soviet Union shocked the world. Humanity’s first artificial satellite, Sputnik 1, entered Earth’s orbit. This small satellite, 58 cm in diameter and weighing 83.6 kg, orbited the Earth for about three months, sending out “beep-beep-beep” signals.^[6]

In the United States, this event was called the “Sputnik Shock.” The fact that the Soviet Union had taken the lead in space technology was a major blow to American pride and raised national security concerns about falling behind in missile technology as well.^[6]

The United States responded immediately. On January 31, 1958, it launched the first American satellite, Explorer 1, and on July 29 of the same year, established NASA (National Aeronautics and Space Administration).^[6]

Yuri Gagarin: The First Human in Space (1961)

On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first human to orbit the Earth aboard Vostok 1. His flight lasted only 108 minutes, but it was a moment that would go down in human history.^[7]

Just before launch, Gagarin exclaimed “Poyekhali! (Let’s go!),” and while looking down at Earth from space, he said, “The Earth is blue. How wonderful.”^[7]

Kennedy’s Moon Landing Declaration

Inspired by Gagarin’s success, President John F. Kennedy delivered a historic speech to the U.S. Congress on May 25, 1961.

“We will land a man on the Moon and return him safely to Earth before this decade is out.”

To achieve this bold goal, the United States invested enormous resources. The total cost of the Apollo program was approximately $25 billion (about $280 billion in today’s value), and at its peak, more than 400,000 people participated in this project.^[8]

4. The Apollo Program: Journey to the Moon

Tragedy and Trials: Apollo 1

The journey of the Apollo program began with tragedy. On January 27, 1967, during a launch rehearsal for Apollo 1, a fire broke out inside the command module, killing three astronauts: Virgil “Gus” Grissom, Edward White, and Roger Chaffee.^[9]

This disaster shocked NASA, but it became an opportunity to drastically improve safety procedures. The spacecraft design was completely reviewed, and numerous changes were made to reduce fire risks.^[9]

Saturn V: The Most Powerful Rocket in History

The centerpiece of the Apollo program was the Saturn V rocket designed by Wernher von Braun. This massive rocket, standing 111 meters tall and weighing 2,970 tons, remains the most powerful rocket ever built by humanity.^[10]

The Saturn V was a three-stage rocket, with five F-1 engines in the first stage generating a total thrust of 34,020 kilonewtons. The noise at launch exceeded 200 decibels, and it is said that buildings shook even about 5 km away.^[10]

Apollo 8: Entering Lunar Orbit (1968)

On December 21, 1968, Apollo 8 became the first manned spacecraft in human history to enter lunar orbit. Frank Borman, James Lovell, and William Anders orbited the Moon 10 times and became the first humans to directly observe the far side of the Moon.^[11]

On Christmas Eve, the astronauts broadcast live to Earth from lunar orbit and read from Genesis Chapter 1. This broadcast was recorded as the most-watched TV program in the world at the time.^[11]

Apollo 11: Humanity’s Giant Leap (1969)

At 9:32 a.m. local time on July 16, 1969, Apollo 11 was launched from the Kennedy Space Center in Florida. The crew consisted of Command Module Pilot Michael Collins, Commander Neil Armstrong, and Lunar Module Pilot Buzz Aldrin.^[1]

On July 20, Armstrong and Aldrin descended to the lunar surface aboard the Lunar Module “Eagle.” The landing process was precarious. When the computer guided them to a boulder-strewn area, Armstrong had to manually take control to find a safer landing spot. Only 25 seconds of fuel remained.^[1]

At 4:17:40 p.m. EDT, the Eagle landed on the Sea of Tranquility. Armstrong reported to ground control: “Houston, Tranquility Base here. The Eagle has landed.”^[1]

Six hours later, at 2:56:15 a.m. UTC on July 21, Neil Armstrong placed his left foot on the lunar surface. Approximately 600 million people around the world watched this historic moment on television.^[1]

Armstrong and Aldrin spent approximately 2 hours and 30 minutes on the lunar surface, collecting 21.5 kg of lunar rock and soil samples. They planted the American flag, installed scientific experimental equipment, and had a phone conversation with President Richard Nixon.^[1]

On July 24, the three astronauts safely splashed down in the Pacific Ocean, successfully completing their mission.^[1]

5. Subsequent Moon Exploration Missions

Apollo 12-17

After Apollo 11, NASA successfully completed five additional manned lunar landings.

• Apollo 12 (November 1969): Charles Conrad and Alan Bean landed in the Ocean of Storms
• Apollo 14 (February 1971): Famous for Alan Shepard hitting a golf ball on the Moon
• Apollo 15 (July 1971): First use of the Lunar Roving Vehicle
• Apollo 16 (April 1972): Exploration of the Descartes Highlands
• Apollo 17 (December 1972): The last manned lunar exploration mission to date^[12]

Apollo 13 experienced an oxygen tank explosion in April 1970, with the famous words “Houston, we’ve had a problem.” Although the lunar landing failed, the astronauts miraculously returned safely to Earth.^[13]

Unmanned Probes and International Lunar Exploration

After the American Apollo program, several countries continued lunar exploration through unmanned probes.

• Soviet Union: Successfully conducted unmanned landings and lunar sample returns through the Luna program
• China: Landed on the Moon for the first time in 37 years with Chang’e 3 in 2013; became the first in the world to land on the far side of the Moon with Chang’e 4 in 2019^[14]
• India: Successfully landed in the lunar south pole region with Chandrayaan-3 in 2023^[15]
• Japan: Successfully landed SLIM (Smart Lander for Investigating Moon) in 2024^[15]

6. The Future: The Artemis Program and a New Lunar Era

The Artemis Program

NASA is pursuing a new lunar exploration program named after Artemis, Apollo’s twin sister. The goal of this program is not simply to return to the Moon, but to build a sustainable lunar base and establish a foundation for Mars exploration.^[16]

Key Timeline

• Artemis 1 (November 2022): Successful unmanned test flight
• Artemis 2 (originally scheduled for 2025 → postponed to March 2026): Manned lunar orbit flight, with launch window expected to open from February to April 2026
• Artemis 3 (originally scheduled for 2026 → postponed to 2028): Scheduled to land humans on the Moon for the first time since 1972, with the first woman astronaut and first person of color expected to set foot on the Moon^[16]

International Cooperation

The Artemis program is an international cooperative project, not a U.S.-only endeavor. Twenty-one countries, including South Korea, have signed the Artemis Accords, agreeing on principles and cooperation methods for space exploration.^[17]

Lunar Gateway

NASA plans to build a small space station called the “Lunar Gateway” in lunar orbit. This will serve as an intermediate base between the lunar surface and Earth and, in the long term, will become a training ground for Mars exploration.^[16]

Conclusion: Humanity’s Continuing Journey

More than half a century has passed since Neil Armstrong took his first step on the Moon on July 20, 1969. That moment was a product of the Cold War, but at the same time, it was an achievement for all of humanity.

From the days when ancient peoples looked up at the Moon in the night sky and created myths, to the early 20th century when Tsiolkovsky calculated rocket equations, to 1961 when Kennedy made his bold promise, and to 1969 when Armstrong achieved “one giant leap for mankind.” The history of moon landing is a symbol of humanity’s process of turning seemingly impossible dreams into reality.

Now we are heading to the Moon again. But this time, it’s to stay. The Artemis program seeks to make the Moon not just a destination, but a place where humanity can live, research, and use as a stepping stone to venture further into space.

Armstrong’s footprints left on the lunar surface will be preserved for millions of years. But what will last even longer is humanity’s spirit of pushing beyond limits to explore the unknown. The Moon is not the end, but the beginning.
