11. Heroes and Villains of the Cold War: The Space Race: Sputnik to the Moon

My Name is Wernher von Braun: Rocket Engineer and Architect of the Saturn V

Long before rockets became weapons of war or machines capable of carrying men to the Moon, I dreamed of traveling into space. I was born in Wirsitz, Germany, in 1912, into an aristocratic family. As a boy, mathematics did not always come easily to me, but everything changed when I discovered the writings of rocket pioneer Hermann Oberth. Suddenly mathematics and physics had a purpose. If mankind intended to leave Earth, we would need equations, engines, fuel, and machines unlike anything yet constructed. I decided that I wanted to help build them.

Building Rockets in Germany

During the 1930s, I studied engineering and physics while working with other Germans interested in rocketry. The German military soon recognized that rockets might have military applications and provided resources far beyond anything civilian experimenters could obtain. At Peenemünde, I became technical director of a program developing increasingly powerful rockets. Our greatest achievement was the A-4, later called the V-2. In October 1942, one successfully flew roughly 190 kilometers and reached an altitude of about 85 kilometers. We had created the first large-scale liquid-fueled ballistic missile.

The V-2 and the War

The engineering achievement could not be separated from the terrible purpose to which the rocket was put. Nazi Germany launched thousands of V-2s against targets including London and Antwerp. Production was moved underground to Mittelwerk, where prisoners from the Mittelbau-Dora concentration camp were forced to manufacture the weapons under brutal and deadly conditions. I had joined the Nazi Party and held rank in the SS, while continuing to pursue rocket development. By 1945, Germany was collapsing, and I understood that the future of rocketry—and perhaps my own future—would be decided by whichever Allied power captured our team.

A New Life in America

Rather than surrender to the Soviet Union, members of my team and I made our way toward American forces. The United States brought me and many other German specialists to America through the program later known as Operation Paperclip. At first, we worked for the U.S. Army, helping develop ballistic missiles and continuing experiments with captured V-2 technology. Eventually I became an American citizen in 1955. I was no longer building rockets for Germany. I was now helping the United States enter a new technological age.

Sputnik Changes Everything

On October 4, 1957, the Soviet Union launched Sputnik 1. Americans could look into the night sky and know that a Soviet-built machine was passing overhead. To me, Sputnik demonstrated something engineers already understood: the Soviet Union possessed powerful rockets. America responded rapidly. My team helped develop the Jupiter-C rocket that launched Explorer 1 on January 31, 1958, America's first successful satellite. Later that year, NASA was established, and the contest moved decisively from experimental rocketry toward human exploration of space.

We Will Go to the Moon

In 1960, my team became part of NASA at the Marshall Space Flight Center in Huntsville, Alabama. Then President John F. Kennedy presented us with an extraordinary objective: land an American on the Moon and return him safely to Earth before the decade was finished. That required something far larger than the rockets we had previously constructed. We needed a machine capable of lifting millions of pounds from Earth and sending men across approximately 240,000 miles of space. The answer became the Saturn V.

Building the Saturn V

The Saturn V stood about 363 feet tall and generated roughly 7.5 million pounds of thrust at liftoff. Yet its size alone was not its greatest achievement. Thousands of engineers, technicians, scientists, manufacturers, and workers had to make enormously complicated systems operate together with extraordinary precision. I often emphasized that great technical accomplishments are rarely the product of one individual. The Saturn V was a national undertaking, and every successful launch represented years of calculations, testing, failures, corrections, and teamwork.

Watching Apollo 11 Rise

On July 16, 1969, I watched Apollo 11 rise from Kennedy Space Center atop a Saturn V. Neil Armstrong, Buzz Aldrin, and Michael Collins were beginning the journey that engineers had imagined for generations. Four days later, Armstrong and Aldrin landed on the Moon. When Armstrong stepped onto its surface, the dream that had fascinated me as a boy had become reality. A machine descended from ideas drawn on paper had carried human beings from one world to another.

From Wartime Rockets to the Beginning of the Space Race - Told by von Braun

1945–1955 - When the Second World War ended in 1945, rockets were already demonstrating a frightening new reality. In Germany, my engineering team had developed the A-4, better known as the V-2, the world's first long-range guided ballistic missile. It could climb beyond the atmosphere during portions of its flight and strike targets hundreds of kilometers away. I had long been interested in the possibility of spaceflight, but during the war our technology became a weapon. When Germany collapsed, the United States and Soviet Union immediately understood that the scientists, machinery, documents, and knowledge behind these rockets might become extraordinarily valuable.

America and the Soviet Union Came Looking

The war in Europe was ending, but another competition was beginning almost immediately. American forces raced to capture German rocket hardware and specialists before the Soviet Union could obtain them. The Soviets did the same in territories they occupied. My colleagues and I deliberately moved west and surrendered to American forces in May 1945. We knew that Germany's rocket program was finished, but rocketry itself was certainly not. Both emerging superpowers wanted to understand how the V-2 worked, and both would use German technology as one foundation for much larger missile programs.

Operation Paperclip Brings Us to America

The United States brought me and more than one hundred members of my rocket team to America through a program that became known as Operation Paperclip. This was controversial, because some of the specialists transferred to the United States—including myself—had worked for Nazi Germany. I had been a Nazi Party member and an SS officer, and V-2 production had used concentration-camp prisoners as forced labor under horrific conditions. Nevertheless, American officials believed German technical knowledge could be strategically valuable, particularly as relations with the Soviet Union deteriorated. By late 1945, members of our group began arriving in the United States.

Launching V-2s in the American Desert

We were sent to Fort Bliss, Texas, and worked with captured V-2 rockets at the White Sands Proving Ground in New Mexico. These launches were important because the rockets were no longer used simply as weapons. Scientists placed instruments aboard them to study the upper atmosphere, cosmic rays, solar radiation, and other phenomena. In 1946, a camera aboard a V-2 took photographs from more than 100 kilometers above Earth, producing some of the earliest images of our planet from space. The weapon that had once descended upon European cities was becoming an instrument for looking outward from Earth.

The Soviets Were Building Their Own Rockets

Across the world, Soviet engineers were moving quickly. They had captured German equipment and specialists, but they were also developing their own expertise under Sergei Korolev. The Soviets first constructed the R-1, heavily based on the V-2, before progressing toward increasingly capable designs. This was becoming much more than scientific curiosity. The United States and Soviet Union were developing rockets primarily because military planners wanted missiles capable of carrying increasingly powerful weapons over greater distances. Space exploration and the missile race were growing from many of the same technologies.

From the V-2 to the Redstone

In 1950, my team moved to Redstone Arsenal in Huntsville, Alabama. There we helped develop the Redstone missile, which represented a substantial advancement beyond the V-2. Better guidance systems, engines, fuels, and manufacturing techniques were steadily increasing what rockets could accomplish. Engineers were learning how to build machines that could fly higher, farther, and more reliably. To military officials, these developments meant improved missiles. To those of us interested in spaceflight, they meant something else: we were approaching the technological ability to place objects into orbit.

Selling America on the Idea of Space

During the early 1950s, I also tried to convince the American public that rockets could serve purposes beyond warfare. I wrote and spoke publicly about space stations, artificial satellites, and expeditions to the Moon. In 1952, Collier's magazine began publishing a widely read series about space exploration to which I contributed. Later, I appeared with Walt Disney in television programs explaining rockets and spaceflight to millions of Americans. What had once sounded like science fiction was becoming a serious engineering possibility. A satellite could circle Earth. Humans might eventually follow it.

1955: The Race Becomes Visible

Then came an announcement that transformed speculation into an international contest. In July 1955, the United States declared that it intended to launch an artificial satellite during the International Geophysical Year of 1957–1958. Only days later, the Soviet Union announced that it too intended to launch a satellite. Neither nation publicly knew exactly what the other could accomplish, but both possessed increasingly powerful rockets. The contest had begun.

The Door to Space Was Opening

By the end of 1955, no nation had yet placed a satellite into orbit and no human being had traveled into space. Yet the essential pieces were coming together: powerful rocket engines, improved guidance systems, military investment, scientific ambition, and two rival superpowers determined to demonstrate technological superiority. The Cold War had given rocketry tremendous resources, although its military purpose carried consequences that could not be ignored. We had begun with rockets designed for war. Now those same principles were pointing upward. The question was no longer whether humanity could reach space. The question was who would get there first.

My Name is Sergei Korolev: Chief Architect of the Soviet Space Program

I was born in 1907 in Zhytomyr, then part of the Russian Empire. From an early age, I was fascinated by machines that could rise above the Earth. I studied aviation and engineering, designed gliders, and eventually became captivated by rockets. Aircraft could cross continents, but rockets offered something greater: the possibility of escaping Earth's atmosphere altogether. By the early 1930s, I was working with other Soviet engineers to turn that possibility into practical technology.

Arrested by My Own Government

In 1938, during Joseph Stalin's Great Purge, everything changed. Soviet authorities arrested me after accusations connected to supposed sabotage. I was interrogated, imprisoned, and eventually sent into the Soviet forced-labor system, including the Kolyma region. The experience damaged my health permanently. Later, I was transferred to a special prison where imprisoned engineers worked on military projects. I had entered prison as a rocket engineer, and somehow engineering became one of the means by which I survived.

The German Rockets

After Germany's defeat in World War II, the Soviet Union captured German rocket technology, equipment, and specialists connected with the V-2 program. We studied the V-2 carefully, just as the Americans were doing. But copying German technology could only be the beginning. If the Soviet Union intended to build missiles capable of traveling enormous distances—and eventually machines capable of reaching space—we needed rockets larger and more powerful than anything Germany had produced.

Building the R-7

My team developed the R-7, the world's first intercontinental ballistic missile. It was enormous, using a central rocket surrounded by four boosters that ignited together at launch. Military leaders saw a weapon capable of carrying a nuclear warhead across continents. I saw something else as well. If a rocket could carry a heavy warhead thousands of kilometers, it could carry a satellite upward with enough speed to enter orbit. The same technology that threatened destruction could open the road into space.

Sputnik

On October 4, 1957, we launched Sputnik 1. It was a polished metal sphere only about 58 centimeters across, but its radio transmitters sent signals that could be detected around the world. Those simple beeps announced something extraordinary: humanity had placed an artificial object into orbit around Earth. The Soviet Union had beaten the United States into space. Soon afterward, Sputnik 2 carried the dog Laika into orbit. The Space Age had begun, and our next objective was already clear. We would send a human being.

Sending Gagarin Into Space

On April 12, 1961, Yuri Gagarin climbed aboard Vostok 1. Years of calculations, experiments, explosions, redesigns, and testing rested inside that spacecraft. When the rocket lifted from Baikonur, Gagarin became the first human to travel into space. He completed one orbit of Earth before returning. The world celebrated Gagarin, as it should have. My own identity, however, remained secret. Soviet newspapers referred to me simply as the Chief Designer. The government believed revealing my name might expose too much about our program.

Reaching Beyond Earth

We did not stop with Gagarin. Soviet spacecraft achieved remarkable firsts: Valentina Tereshkova became the first woman in space in 1963, and Alexei Leonov performed the first spacewalk in 1965. Our robotic Luna program also reached toward the Moon. I wanted something greater still—a Soviet mission that could send cosmonauts around the Moon and eventually place them upon its surface. The Americans had announced the same objective. The competition had moved from Earth's orbit toward another world.

The Cost of Secrecy and Speed

The Soviet system demanded results, and failure could carry consequences far beyond embarrassment. We worked under tremendous political pressure while technical problems multiplied as our rockets and spacecraft became more complicated. There were accidents, including the catastrophic Nedelin disaster of 1960 involving another Soviet missile program. Much of this remained hidden from the public. To the outside world, Soviet space achievements appeared almost effortless. Engineers knew differently. Every successful launch stood upon thousands of tests, mistakes, risks, and sometimes lives.

I Would Not See the Moon Landing

My health had never fully recovered from imprisonment, exhausting work, and years of tremendous pressure. In January 1966, I entered a Moscow hospital for surgery and died at only fifty-nine. Only after my death did the Soviet government publicly reveal that Sergei Korolev had been the Chief Designer behind many of its greatest space achievements. Three years later, Americans would walk upon the Moon. I did not live to see it.

The Secret Race to Put Something Into Orbit - Told by Sergei Korolev

1955–1957 - In July 1955, the United States announced that it intended to place an artificial satellite into orbit during the coming International Geophysical Year. Only days later, the Soviet Union announced that we intended to do the same. To the public, this sounded like a peaceful scientific competition. Inside our rocket programs, however, we understood what was truly at stake. A satellite orbiting Earth would demonstrate that its nation possessed extraordinarily advanced rockets—and the Soviet Union intended to be first.

I Needed a Rocket Powerful Enough to Do It

My greatest advantage was a machine originally designed for a very different purpose. My engineers were developing the R-7 Semyorka, an enormous rocket intended to carry a nuclear warhead across intercontinental distances. It consisted of a central core surrounded by four strap-on boosters, with engines firing together at liftoff. The military wanted an intercontinental ballistic missile. I looked at the same machine and saw something more. If it could accelerate a heavy warhead across the world, it could accelerate a smaller scientific object fast enough to remain above the world.

The Secret Was Speed

People sometimes imagine that reaching space simply requires going high enough. That is not the real difficulty. To orbit Earth, an object must also travel sideways at approximately 28,000 kilometers per hour. At that speed, gravity continually pulls the spacecraft downward while the curved surface of Earth falls away beneath it. The spacecraft is, in effect, continuously falling around the planet. Achieving that velocity required enormous power, precise guidance, and engines that had to function correctly together. One serious malfunction could destroy the entire vehicle.

The R-7 Refused to Cooperate

In May 1957, we attempted the first launch of the R-7. It failed. Another attempt in June did not even leave the launch pad successfully because of technical trouble. A July flight also failed after launch. There is nothing unusual about failure in experimental engineering, although political leaders are not always patient enough to appreciate this fact. We studied the telemetry, examined components, corrected problems, and prepared another rocket. On August 21, 1957, the R-7 finally completed a successful long-range test flight. We now possessed something the Americans did not yet know we could reliably operate: a rocket powerful enough to reach orbital velocity.

Forget the Complicated Satellite

Our original satellite plans were ambitious. Scientists wanted to launch a large laboratory known as Object D, packed with scientific instruments. But its development was taking too long. I feared that while we waited for perfection, the Americans might reach orbit first. I therefore pushed for something simpler: PS-1, meaning "Elementary Satellite-1." It would be a polished metal sphere about 58 centimeters across, weighing roughly 83.6 kilograms, equipped with batteries, antennas, and radio transmitters. It did not need to be complicated. It needed to reach orbit before the Americans.

The Americans Chose Vanguard

Across the ocean, the United States was preparing Project Vanguard as its official satellite program. American engineers also had other rockets under development, including those associated with Wernher von Braun's Army team, but political and military considerations shaped which project received permission to attempt the first American satellite launch. We watched whatever information became publicly available. They watched us as well, although the secrecy surrounding Soviet engineering made their task considerably more difficult. Even my own name was kept from the world. I was simply the Chief Designer.

October 4, 1957

At Baikonur, our R-7 stood ready with PS-1 mounted above it. On October 4, the engines ignited and the rocket climbed into the darkness. The boosters separated. The central stage continued upward. Then we waited for confirmation. Finally came the signal we needed: the satellite had achieved orbit. PS-1 was circling Earth approximately once every 96 minutes. We had done it. Humanity had placed its first artificial satellite above the planet.

A Tiny Sphere With an Enormous Voice

We called it Sputnik, meaning "fellow traveler" or "traveling companion." Its radio transmitters produced simple repeating beeps that amateur radio operators and tracking stations around the world could detect. That simplicity made the achievement even more powerful. People did not need to trust a Soviet newspaper claiming we had reached space. They could listen to the signal themselves. A metal sphere weighing less than an adult man was passing repeatedly over the United States and the rest of the world.

The Secret Race Was Secret No Longer

For two years, engineers in both nations had raced toward an objective most ordinary people scarcely understood. On October 4, 1957, that hidden competition suddenly became one of the greatest public contests of the Cold War. Sputnik was a scientific achievement, but no American military planner could ignore the rocket beneath it. If the Soviet Union could launch a satellite over Earth, what else might such rockets carry across continents? We had won the first great contest of the Space Age, but I knew there would be another question almost immediately. If we could send a machine into space, could we send a man?

Sputnik Shocks America and Changes the Cold War - Told by Korolev

1955–1957 - On October 4, 1957, the rocket rose from Baikonur carrying a polished metal sphere only 58 centimeters wide. When Sputnik 1 separated and entered orbit, its transmitters began sending a simple radio signal: beep, beep, beep. To us, those signals meant that the calculations had worked and humanity's first artificial satellite was circling Earth. But across the ocean, those same beeps sounded like an alarm. The Soviet Union had reached space before the United States.

Why Sputnik Frightened America

Sputnik itself carried no weapon. It weighed about 83.6 kilograms and contained little more than radio equipment, batteries, and instruments for monitoring conditions inside the satellite. Yet Americans understood that the satellite had not climbed into orbit by itself. Our R-7 rocket had put it there. If the Soviet Union possessed a rocket powerful enough to send a satellite around Earth, Americans naturally wondered whether similar technology could send a nuclear warhead across the world. The Space Race and missile race were connected, and Sputnik made that connection impossible to ignore.

America Had Expected to Lead

The United States was one of the world's greatest scientific and industrial powers. American leaders had already announced plans to launch a satellite during the International Geophysical Year of 1957–1958, and many Americans assumed their nation would lead the new Space Age. Instead, they could step outside at certain times and know that a Soviet object was passing overhead. Newspapers devoted enormous attention to the launch. Politicians demanded explanations. Scientists warned that the United States needed greater investment in research and education. Suddenly, the question was not simply what America had accomplished, but how the Soviets had beaten them.

Then We Sent Up Sputnik 2

We did not allow the Americans much time to recover. Soviet leaders wanted another spectacular achievement for the approaching fortieth anniversary of the Bolshevik Revolution. On November 3, 1957, less than a month after Sputnik 1, we launched Sputnik 2. This spacecraft was much heavier—about 508 kilograms—and carried a living passenger, a dog named Laika. There was no practical system for returning her safely to Earth, and she died from overheating within hours of launch, though Soviet authorities did not reveal the true circumstances at the time. Scientifically and ethically, the mission carried a heavy cost. Politically, however, the message was unmistakable: the Soviet Union had launched something far larger than Sputnik 1 and had placed a living creature into orbit.

America's Vanguard Falls Back to Earth

Then came an event we could hardly have designed better for Soviet propaganda. On December 6, 1957, the United States attempted to launch its Vanguard TV3 satellite before television cameras. The rocket rose only slightly from the launch pad before losing thrust, falling back, and exploding. The small satellite was thrown clear and reportedly continued transmitting after the accident. American newspapers mocked the failure with names such as "Flopnik" and "Kaputnik." Rocket failures were nothing unusual—we had experienced plenty ourselves—but America's happened publicly at exactly the wrong moment.

A Victory for Soviet Propaganda

Nikita Khrushchev understood the political value immediately. Soviet propaganda presented Sputnik as evidence that socialism could produce scientific and technological achievements equal or superior to those of the capitalist West. Around the world, nations that had previously thought of the Soviet Union primarily as a massive land power now saw a country capable of sophisticated engineering. The competition was especially important in newly independent countries where Washington and Moscow were competing for influence. A satellite could not conquer territory, but it could influence how millions of people judged the strength of the two systems.

My Name Remained a Secret

There was one strange feature of our victory: the world was not permitted to know who had designed much of it. The Soviet government concealed my identity because I knew too much about our missile and space programs. Western intelligence agencies might have wanted information about me, and our leaders preferred secrecy. Yuri Gagarin would later become one of the most recognizable men on Earth, but during these early victories I remained publicly anonymous—the mysterious Chief Designer. That was the Soviet way. Individual fame mattered less than presenting the achievement as a triumph of the state.

The Americans Begin to Respond

Sputnik did not prove that the United States was permanently behind. In fact, our success awakened an enormous competitor. Wernher von Braun's Army team and the Jet Propulsion Laboratory moved forward with another American satellite attempt. On January 31, 1958, Explorer 1 successfully reached orbit and helped discover the Van Allen radiation belts. The United States would soon create NASA and devote greater resources to science, engineering, missiles, and space exploration. Sputnik had embarrassed America, but embarrassment can be a powerful motivation.

We Had Changed the Cold War

Before October 1957, the Cold War was already being fought through armies, alliances, nuclear weapons, intelligence agencies, economics, and ideology. Sputnik added something new: technological achievement before the eyes of the entire world. From that moment forward, every satellite, rocket, cosmonaut, and astronaut could become evidence in the contest between the United States and Soviet Union. We had won the first round. But as an engineer, I knew better than to celebrate for too long. America was now fully awake, and the next contest would be far more difficult: putting a human being into space.

Dogs, Satellites, and Machines Become the First Space Explorers - Told by Korolev

After Sputnik 1 reached orbit on October 4, 1957, there was little time to admire what we had accomplished. A machine could survive space, but could a living creature? Before I could seriously propose sending a cosmonaut into orbit, we needed answers. Could a body tolerate launch acceleration? Could it survive weightlessness? Could life-support equipment function above Earth? There was only one way to learn. We had to send living passengers before we sent human beings.

Why We Chose Dogs

The Soviet program had been experimenting with dogs aboard high-altitude rockets since the early 1950s. We generally selected small dogs, often females and frequently strays from Moscow, because they could fit inside compact cabins and seemed well suited to harsh conditions. Scientists trained them to remain in confined spaces and tolerate vibrations and acceleration. These animals were not mascots. They were part of serious biomedical experiments designed to determine whether living organisms could survive the conditions that future cosmonauts would face.

Laika Goes Into Orbit

After Sputnik's success, Nikita Khrushchev wanted another spectacular achievement in time for the fortieth anniversary of the Bolshevik Revolution. We were given only weeks to prepare Sputnik 2. Our passenger was Laika, a small dog selected from our training group. On November 3, 1957, she became the first animal to orbit Earth. Sensors monitored her heartbeat, breathing, and movements. The launch demonstrated that a living creature could survive the tremendous forces required to reach orbit and remain alive during weightlessness—at least for a time.

A Mission Without a Return

There is a difficult truth about Laika's flight. Sputnik 2 had no system capable of bringing her safely home. Soviet authorities initially gave misleading accounts suggesting she survived for days, but evidence revealed decades later showed that she died within hours from overheating and stress after the spacecraft's thermal-control system failed. We learned from the mission, but Laika paid for that knowledge with her life. If humans were going to follow, simply reaching orbit would not be enough. We needed to learn how to return them alive.

Machines Head for the Moon

Animals were not our only explorers. Robotic spacecraft could travel where humans were not yet prepared to go. In January 1959, Luna 1 became the first spacecraft to escape Earth's gravity and pass near the Moon, although it missed its intended impact. In September, Luna 2 successfully struck the Moon, becoming the first human-made object to reach another celestial body. Then Luna 3 flew around the Moon in October and photographed something no human being had ever seen: much of the Moon's far side.

The Hidden Face of Another World

For all of human history, people had looked at essentially the same side of the Moon because the Moon rotates once during each orbit around Earth. Luna 3 changed that. Its photographs were crude by later standards, but when they were transmitted back to Earth, we were seeing landscapes that had never before been visible to human eyes. Mountains, craters, and enormous regions appeared on our photographic images. A Soviet machine had become humanity's eyes where no person could yet travel.

America Was Learning Too

The Americans were conducting their own experiments. Their early Pioneer lunar probes suffered several failures, demonstrating again that spaceflight was extraordinarily unforgiving. But American satellites were also producing important discoveries. Explorer 1, launched in 1958, carried an experiment designed by James Van Allen's team that helped reveal belts of energetic particles surrounding Earth. Space exploration was becoming more than a competition over flags and headlines. Satellites were beginning to reveal things about our planet and its surroundings that scientists had never known.

Belka and Strelka Come Home

Our decisive biological test came in August 1960. Sputnik 5 carried the dogs Belka and Strelka, along with other biological specimens, into orbit. Unlike Laika, they returned safely to Earth after completing 17 orbits. They became the first animals to orbit Earth and return alive. For my engineers and physicians, their recovery was far more important than celebrity photographs. It demonstrated that a living passenger could launch into orbit, experience weightlessness, survive reentry, and come home.

The Next Passenger Would Be Human

By early 1961, the pieces were coming together. Sputnik had proved that we could reach orbit. Luna spacecraft had traveled to the Moon. Dogs had shown that living creatures could survive spaceflight and return. Our Vostok spacecraft was being tested for the next step. Machines and animals had gone ahead of us because they could take risks we were not yet prepared to ask a human being to take. But every successful mission brought us closer to the moment I had been working toward for years. The next explorer would not transmit only radio signals or photographs. He would look through a window, see Earth beneath him, and tell us what space looked like with human eyes.

My Name is Yuri Gagarin: First Human in Space

I was born in 1934 in the village of Klushino, west of Moscow. My parents worked on a collective farm, and ours was not a life of luxury. When Germany invaded the Soviet Union, my village was occupied, and my family endured hunger, fear, and hardship. I was still a boy, but I watched aircraft cross the sky above us. War taught me what machines could do in destruction. Later, I would discover what flying machines could accomplish for exploration.

Learning to Fly

After the war, I studied at a vocational school and then continued my education in Saratov. There I joined a flying club and climbed into an aircraft for the first time. I knew immediately that I wanted to fly. I entered military aviation training and became a Soviet Air Force pilot. Flying demanded discipline. A pilot could feel excitement, certainly, but emotion could not control his hands. Instruments, procedures, calculations, and training came first.

A New Kind of Pilot

In 1960, I was selected with a small group of pilots for the Soviet cosmonaut program. We did not entirely know what awaited us because no human being had ever traveled into space. We endured centrifuges, isolation chambers, parachute training, medical examinations, and endless technical instruction. I was small enough to fit comfortably inside the cramped Vostok capsule, but physical size was only one consideration. The engineers needed someone who could remain calm when there was no previous experience to tell him exactly what would happen.

The Morning of April 12, 1961

Before dawn on April 12, 1961, I prepared for Vostok 1 at the Baikonur Cosmodrome. Sergei Korolev and his engineers had constructed the machine that would carry me beyond Earth. I was strapped into the capsule atop the enormous rocket and waited. Then the engines came alive. As we lifted from the ground, I called out, "Poyekhali!"—"Let's go!" It was a simple expression, perhaps more enthusiastic than the official language of reports and procedures, but there are moments when even a disciplined cosmonaut may be permitted some excitement.

I Saw the Earth

Soon I was weightless. Objects floated around the cabin, and beneath me was something no human being had ever seen with his own eyes: Earth from orbit. I could see clouds, oceans, land, and the curve of the horizon. The transition from daylight to darkness was magnificent. Yet there was work to perform. I monitored the spacecraft, communicated with the ground, and observed how my body reacted to weightlessness. Vostok carried me around Earth at roughly 27,000 kilometers per hour. The entire flight lasted only 108 minutes, but those minutes changed human history.

Returning From Space

Coming home was dangerous. Vostok was not designed for me to remain inside the capsule all the way to the ground. After reentry, I ejected several kilometers above Earth and descended separately by parachute. I landed near the Volga River, where local people were understandably surprised to see a man in an orange flight suit descending from the sky. I had left Earth as a Soviet military pilot. I returned as the first human being to have traveled into outer space.

A Hero of the Soviet Union

My government quickly made me a symbol of Soviet achievement. I traveled throughout the Soviet Union and abroad, meeting workers, politicians, students, and enormous crowds. I smiled often—I suppose that became part of my reputation. But behind the celebrations stood thousands of engineers, technicians, doctors, and workers whose names were rarely known outside the program. I had flown the spacecraft, but I had not built it. Spaceflight was never the accomplishment of one man.

I Wanted to Fly Again

Fame was not enough for me. I was a pilot and cosmonaut, and I wanted to return to flight. Soviet leaders were reluctant to risk the life of such a valuable national symbol, but I continued training and became involved with the developing Soyuz program. I also returned to flying military aircraft. I did not want my life to become a museum exhibit devoted to a single morning in 1961. There was more to learn, more to test, and much farther for humanity to travel.

My Final Flight

On March 27, 1968, I flew a MiG-15UTI training aircraft with instructor Vladimir Seryogin. Something went terribly wrong during the flight, and our aircraft crashed near Kirzhach. We were both killed. I was thirty-four years old. I did not live to see Apollo 11 reach the Moon the following year, nor did I see the decades of exploration that followed. But I had seen Earth from a place where no person had seen it before.

Yuri Gagarin Becomes the First Human in Space - Told by Yuri Gagarin

April 12, 1961 - Before sunrise at the Baikonur Cosmodrome, I put on my orange pressure suit and prepared to climb aboard Vostok 1. I was twenty-seven years old, a Soviet Air Force pilot, husband, and father. No human being had ever traveled into outer space. Sergei Korolev's engineers believed the spacecraft was ready, our doctors believed a man could survive the journey, and I had been trained for emergencies. Still, there was one fact no amount of training could change: someone had to be first.

Why They Chose Me

Twenty Soviet pilots had originally been selected for cosmonaut training. We endured centrifuges, isolation chambers, parachute jumps, medical examinations, weightlessness training, and technical instruction. Eventually the choice narrowed to German Titov and me, with me selected for the first flight. My small size helped because Vostok's cabin was extremely cramped, but temperament mattered as well. A cosmonaut needed to remain calm, follow procedures, communicate clearly, and continue functioning when confronted by something no pilot had experienced before.

Strapped to an R-7

Vostok 1 sat atop a modified version of Korolev's R-7 rocket—the same basic family of rockets that had launched Sputnik. I entered the spherical descent module and was secured into my seat. Technicians closed the hatch, but a problem with an electrical contact forced them to reopen it and make adjustments before sealing me inside again. That was not the most reassuring final preparation, but engineering rarely provides drama at convenient times. Once everything was ready, there was nothing left to do but wait.

"Poyekhali!"

At 9:07 in the morning Moscow time, the engines reached full power. As the rocket began to rise, I exclaimed, "Poyekhali!"—"Let's go!" The acceleration pressed me into my seat as the boosters carried Vostok upward. Stages separated beneath me, and within minutes the engines stopped. Suddenly the tremendous vibration was gone. My body became weightless. I had left Earth. For the first time in history, a human being was orbiting our planet.

The Earth Was Beautiful

Through the window, I saw something no person had ever witnessed directly. Earth curved beneath me, bright against the darkness of space. I could see clouds, terrain, and the horizon surrounded by a thin atmosphere. I reported that weightlessness was tolerable and that I could work normally. Objects floated inside the cabin. My body felt strange, certainly, but I remained alert. I remember the beauty very clearly. From orbit, our enormous world suddenly appeared finite.

Flying a Spacecraft I Barely Controlled

There is something students should understand about Vostok: I was not piloting it like an airplane. Soviet officials worried that weightlessness might impair human judgment, so the spacecraft operated largely automatically. A sealed code was available that could unlock manual controls if necessary. Ground controllers and automated systems handled most of the flight while I observed, communicated, and recorded my reactions. I completed one orbit of Earth, traveling at roughly 27,000 kilometers per hour.

Reentry Was Not Simple

After about an hour in space, Vostok's retrorockets fired to bring me home. The equipment module was supposed to separate cleanly from my descent capsule, but cables temporarily kept the sections connected. The spacecraft began tumbling violently during reentry until the cables finally burned through and the capsule stabilized. I endured intense gravitational forces as the atmosphere slowed me. Space had been beautiful. Coming back reminded me that it was also extremely dangerous.

I Did Not Land Inside Vostok

At about seven kilometers above the ground, I ejected from the capsule exactly as the Vostok system was designed to require and descended separately by parachute. I came down near the Volga River in the Saratov region. A woman and a young girl reportedly saw this strange figure in an orange suit and helmet approaching them. I reassured them that I was Soviet and had come from space. It was an unusual introduction.

One Hundred and Eight Minutes

From launch to landing, my journey lasted approximately 108 minutes. That was all. Yet in those 108 minutes, a boundary that had existed throughout human history disappeared. The Soviet Union announced the achievement to the world, and I was soon surrounded by celebrations, speeches, crowds, and international attention. The flight was presented as a great Soviet victory, and it certainly was an extraordinary accomplishment by Korolev and thousands of Soviet workers, scientists, physicians, and engineers.

The Race Had Changed Again

I was proud to represent my country, but I also understood that America would answer. Alan Shepard would fly into space less than a month later, and President John F. Kennedy would soon challenge the United States to land a man on the Moon. Our flight had not ended the Space Race. It had made the race far larger. Sputnik proved machines could orbit Earth; I had proved humans could do it. Now both superpowers would look beyond Earth orbit toward the Moon. For 108 minutes I had been alone above the planet, but I knew very well that many others would soon follow.

My Name is Neil Armstrong: First Human to Walk on the Moon

I was born in Wapakoneta, Ohio, in 1930. I became interested in airplanes when I was a boy, long before anyone seriously talked about sending Americans to the Moon. I built model airplanes, read about aviation, and earned my student pilot certificate when I was sixteen—before I had a driver's license. Flying fascinated me because it combined engineering, judgment, and skill. I did not know where aviation would take me. I simply knew that I wanted to understand how machines flew.

War in Korea

I studied aeronautical engineering at Purdue University through a Navy scholarship, but my education was interrupted when I was called to active duty. During the Korean War, I flew 78 combat missions as a naval aviator. On one mission, my aircraft was damaged after striking a cable while flying low, and I was forced to eject. Combat flying taught me to remain focused when circumstances changed rapidly. Panic is of little assistance to a pilot. You identify the problem, consider your options, and act.

Becoming a Test Pilot

After Korea, I returned to Purdue and completed my engineering degree. I then became a research and test pilot for the organization that preceded NASA. At Edwards Air Force Base, I flew many experimental aircraft, including the X-15 rocket plane. Test pilots deliberately flew machines near their limits so engineers could discover what worked and what did not. There was risk, certainly, but the purpose was not excitement. The purpose was information. Every flight was an engineering experiment conducted in the sky.

Joining the Astronaut Corps

In 1962, NASA selected me for its second group of astronauts. President John F. Kennedy had already challenged the United States to land a man on the Moon before the decade ended. That was an extraordinary objective. We still needed to learn how astronauts could work for long periods in space, maneuver spacecraft, rendezvous, dock, and survive the journey home. Before we could walk on the Moon, we had to learn how to reach it.

Gemini 8 Spins Out of Control

In March 1966, David Scott and I flew Gemini 8 and successfully completed the first docking of two spacecraft in orbit. Shortly afterward, however, our spacecraft began rolling. The rotation became increasingly violent, eventually approaching one revolution per second. We determined that a thruster on Gemini was stuck open. I shut down the main control system and used the reentry thrusters to stop the spin. The mission had to be ended early. It was disappointing, but we returned safely. Spaceflight has very little respect for schedules or expectations.

Apollo 11

In 1969, NASA assigned me to command Apollo 11 with Buzz Aldrin and Michael Collins. On July 16, we lifted from Kennedy Space Center aboard the Saturn V, the enormous rocket developed by thousands of people, including Wernher von Braun's team. We traveled approximately 240,000 miles toward the Moon. Collins would remain in lunar orbit aboard Columbia while Buzz and I descended toward the surface in the lunar module Eagle. After years of preparation, the objective was becoming very immediate.

The Eagle Was Running Out of Time

Our descent did not proceed exactly as planned. Computer alarms sounded, and when I looked outside, I could see that the automatic guidance system was carrying us toward an area filled with rocks and craters. I took more direct control and guided Eagle toward a safer location. Our fuel supply was becoming quite low. When the landing probes finally touched the surface, I shut down the engine and reported, "Houston, Tranquility Base here. The Eagle has landed." There was relief, but there was also work to do.

One Small Step

Several hours later, I descended the ladder and stepped onto the Moon. I said, "That's one small step for [a] man, one giant leap for mankind." Buzz soon joined me. We collected samples, photographed the surface, deployed scientific experiments, and planted the American flag. I understood the importance of the moment, but it never seemed appropriate to think of Apollo 11 as the achievement of three astronauts. Hundreds of thousands of people had contributed to the Apollo program. We were simply the crew fortunate enough to make that particular flight.

Coming Home

We left the lunar surface, reunited with Michael Collins, and began the journey back to Earth. On July 24, Columbia splashed down in the Pacific Ocean. The mission had lasted a little over eight days. America had fulfilled Kennedy's challenge before the decade ended, but something larger had happened as well. Human beings had traveled to another world, walked upon it, and returned safely. For an engineer and pilot, it was difficult to imagine a more remarkable demonstration of what disciplined teamwork could accomplish.

America Accepts the Challenge and Women Enter the Race - Told by Armstrong

1961–1963 - In the spring of 1961, I was still a test pilot, not yet an astronaut, but anyone working in American aviation understood what Yuri Gagarin's flight meant. On April 12, the Soviet Union had placed the first human being into orbit. Sputnik had already demonstrated Soviet capability in 1957; now Gagarin had shown that their lead extended to human spaceflight. For the United States, the question was no longer whether space exploration mattered. The question was how we intended to respond.

Alan Shepard Takes America's First Step

The answer began on May 5, 1961, when Alan Shepard climbed aboard Freedom 7. His Mercury spacecraft was launched by a Redstone rocket and carried him on a suborbital flight lasting just over fifteen minutes. Shepard did not orbit Earth as Gagarin had, but he became the first American in space and demonstrated that an American astronaut could function during launch, weightlessness, and reentry. It was a short flight measured by time, but an important one measured by what America needed to learn.

Kennedy Chooses the Moon

Twenty days later, President John F. Kennedy addressed Congress and proposed something extraordinary: the United States should land a man on the Moon and return him safely to Earth before the decade was over. At that moment, America had accumulated only minutes of human spaceflight. We did not yet know how to rendezvous two spacecraft in orbit, dock them together, keep astronauts working in space for many days, or land a spacecraft on another world. Kennedy had selected an objective beyond the existing capability of either superpower. That was precisely what made it a race America believed it might still win.

John Glenn Orbits the Earth

America's next great milestone came on February 20, 1962. John Glenn entered Friendship 7 atop an Atlas rocket and became the first American to orbit Earth. He completed three orbits during a flight lasting nearly five hours. At one point, controllers received an indication suggesting that the spacecraft's heat shield might be loose, creating serious concern about reentry. Glenn returned safely, splashing down in the Atlantic. He became a national hero, and the United States had finally demonstrated that it too could send a human around the planet.

I Join NASA

That same year, NASA selected its second group of astronauts. I applied and was accepted in September 1962. I came from the world of engineering and experimental aircraft, including flights in the X-15. The astronaut corps was moving beyond the earliest Mercury missions toward something considerably more complicated. Reaching the Moon would require a progression: Mercury would demonstrate that humans could operate in space, Gemini would teach us how to maneuver and work there, and Apollo would attempt the lunar journey itself. Nobody was going directly from a few Earth orbits to the Moon.

The Soviets Keep Moving

Meanwhile, the Soviet program continued producing dramatic achievements. In August 1962, Vostok 3 and Vostok 4 orbited at the same time, placing two crewed Soviet spacecraft in orbit simultaneously. Although they did not rendezvous in the later technical sense, the mission demonstrated increasingly ambitious operations. The message was difficult to miss. Every time the United States appeared to close part of the gap, Sergei Korolev's program seemed prepared to announce another first.

Valentina Tereshkova Makes History

Then, on June 16, 1963, Valentina Tereshkova launched aboard Vostok 6 and became the first woman in space. She had worked in a textile factory and was an experienced amateur parachutist before being selected for cosmonaut training. During nearly three days in space, she completed 48 orbits of Earth. No American woman would travel into space until Sally Ride in 1983. Whatever political value Soviet leaders saw in Tereshkova's mission, the historical fact remained remarkable: less than six years after Sputnik, both men and women had now traveled beyond Earth's atmosphere.

The Moon Was Becoming the Finish Line

By the end of 1963, the Space Race had changed dramatically. The Soviet Union had launched the first satellite, first man, and first woman into space. America had answered with Shepard, Glenn, an expanding astronaut corps, and something the Soviets had not publicly matched: a national commitment to place humans on the Moon. Kennedy did not live to see that challenge completed; he was assassinated in November 1963. But the objective remained. We were no longer simply trying to catch the Soviet Union one achievement at a time. We were preparing for a destination nearly 240,000 miles away—and reaching it would require us to learn how to do things no human being had ever attempted.

1964–1966 — Gemini: Learning How to Reach the Moon - Told by Neil Armstrong

1964–1966 - President Kennedy had challenged us to land a man on the Moon before the decade ended, but in 1964 we still lacked many of the skills required to do it. Mercury had proved that Americans could survive and work in space. Apollo would eventually attempt the Moon. Between them stood Gemini. Its missions had to teach us how to remain in space for days, change orbits, rendezvous with another spacecraft, dock, work outside the capsule, and return accurately to Earth. Gemini was our classroom, except mistakes in this classroom could be fatal.

Two Astronauts in a Very Small Space

Gemini carried two astronauts instead of Mercury's one, but the spacecraft was remarkably cramped. We sat beside one another surrounded by switches, instruments, equipment, and very little room to move. Unlike Mercury, Gemini gave astronauts substantial control over maneuvering the spacecraft. That was essential. A lunar mission would require astronauts to meet other spacecraft hundreds of miles above Earth. We could not simply be passengers. We had to become pilots in space.

America Steps Outside

Gemini 4 launched in June 1965 with James McDivitt and Ed White aboard. During the mission, White opened the hatch and floated outside, becoming the first American to perform a spacewalk, following Soviet cosmonaut Alexei Leonov's first-ever spacewalk that March. White remained outside for about twenty-three minutes and clearly enjoyed the experience. But working outside a spacecraft was more difficult than photographs suggested. Later Gemini missions demonstrated that astronauts could quickly exhaust themselves when attempting physical tasks in weightlessness. We had to learn how to move, secure ourselves, and work efficiently.

Learning to Find Each Other in Space

One of Gemini's most important lessons involved rendezvous. It sounds simple: if another spacecraft is ahead of you, point toward it and accelerate. Orbital mechanics does not work that way. Increasing speed can move you into a higher orbit where you actually travel around Earth more slowly. In December 1965, Gemini 6A, carrying Wally Schirra and Tom Stafford, successfully rendezvoused with Gemini 7, which carried Frank Borman and Jim Lovell. The spacecraft came within about a foot of each other. Humans had demonstrated that two independently launched spacecraft could deliberately meet in orbit.

Gemini 8: My Turn

On March 16, 1966, David Scott and I launched aboard Gemini 8. Our primary target was an uncrewed Agena vehicle already waiting in orbit. We had to locate it, approach carefully, match its motion, and connect the two spacecraft. Several hours after launch, I guided Gemini toward the Agena. We moved closer until the docking mechanism engaged. We had done it—the first successful docking of two vehicles in space. For the Moon program, this was an essential achievement.

Then We Started Rolling

Not long after docking, however, I noticed that our combined spacecraft were beginning to roll. We attempted to correct the motion, but it returned. We suspected the Agena, so we undocked. That made the situation dramatically worse. Gemini began spinning faster and faster. The problem was actually one of our own thrusters, which had become stuck open. Our rotation eventually approached one revolution per second. At that rate, David and I could have lost consciousness, and if that happened, the spacecraft would have been lost.

Stopping the Spin

There was no time for a committee meeting. I shut down the malfunctioning orbital maneuvering system and activated the reentry control system. Those thrusters were intended primarily to control the spacecraft during our return to Earth, but they stopped the rotation. We were safe, although using that system meant mission rules required us to come home early. We had planned a mission lasting several days. Instead, we splashed down less than eleven hours after launch. It was disappointing, but disappointment is preferable to not returning.

Gemini Kept Going

The program continued. Later crews demonstrated increasingly sophisticated rendezvous and docking techniques. Astronauts learned how to work outside the spacecraft using improved restraints and handholds. Gemini 7 had already shown that humans could remain in space for nearly fourteen days—longer than an Apollo lunar mission would require. By Gemini 12 in November 1966, Buzz Aldrin demonstrated that carefully planned spacewalks could be performed effectively without exhausting the astronaut.

We Had Learned How to Reach the Moon

Gemini never traveled to the Moon, yet Apollo could scarcely have succeeded without it. By the end of 1966, NASA had learned how to rendezvous, dock, maneuver, conduct extended missions, work outside spacecraft, and solve emergencies hundreds of miles above Earth. We had also learned something less technical but equally important: spaceflight would rarely proceed exactly according to plan. The Moon was still nearly 240,000 miles away, but Gemini had given us the tools to attempt the journey. Now we needed to build the spacecraft—and survive the final lessons before Apollo could take us there.

Disaster, Sacrifice, and Race Around the Moon - Told by Armstrong and Gagarin

The Race Had Become Dangerous

Neil Armstrong: By 1967, both of our countries were moving quickly toward the Moon, perhaps more quickly than the machines sometimes permitted. America had completed Gemini and was preparing Apollo. The Soviet Union was developing Soyuz and several possible lunar systems. From the outside, people saw launches, records, and national victories. Inside the programs, we saw something else as well: thousands of components that had to work correctly in an environment where even a small failure could kill a crew.

Yuri Gagarin: We understood this in the Soviet Union too. Every success created pressure for another success. Sergei Korolev, the great Chief Designer who had guided Sputnik and my Vostok flight, died unexpectedly in January 1966. His death was an enormous loss. The Soviet lunar program continued, but without his leadership it faced technical problems and competing organizations. The Americans were moving toward Apollo while we were trying to make Soyuz reliable. Neither side could afford to treat spaceflight casually.

Apollo 1 Burns on the Ground

Neil Armstrong: On January 27, 1967, astronauts Gus Grissom, Ed White, and Roger Chaffee entered the Apollo 1 command module at Cape Kennedy for what was supposed to be a ground test. They never left Earth. A fire erupted inside the cabin, which was filled with pure oxygen at high pressure. Flames spread rapidly through combustible materials, and the inward-opening hatch could not be opened quickly. All three men died. NASA had not lost astronauts in space; we lost them sitting on the launch pad.

Yuri Gagarin: We heard about the American deaths, and there was no satisfaction among cosmonauts in such news. Grissom, White, and Chaffee were doing the same kind of work we were doing. Their deaths also carried a warning. A spacecraft did not have to leave Earth to become dangerous. In both countries, schedules and political expectations were pressing against engineering reality. Space did not care whether a flag was American or Soviet.

Soyuz 1 Ends in Tragedy

Yuri Gagarin: Only three months later, tragedy came to us. On April 23, 1967, my friend Vladimir Komarov launched aboard Soyuz 1. Problems appeared almost immediately. One solar panel failed to deploy, reducing electrical power and interfering with spacecraft systems. The planned launch of a second Soyuz was canceled, and controllers decided to bring Komarov home. He survived the difficult reentry, but during the final descent his main parachute failed to deploy properly, and the reserve parachute became entangled. Soyuz struck the ground at tremendous speed on April 24. Vladimir was killed.

Neil Armstrong: Komarov became the first person to die during a spaceflight mission. Americans did not know every detail at the time because the Soviet program operated under considerable secrecy, but we understood the larger lesson. Our nations were competitors, yet the engineering problems were universal. Parachutes, electrical systems, oxygen, guidance equipment—none of them recognized ideology. Apollo 1 forced NASA to redesign major portions of our spacecraft. Soyuz 1 forced the Soviets to confront serious flaws in theirs.

The Moon Was Still Waiting

Neil Armstrong: NASA did not abandon Apollo after the fire. Engineers examined the spacecraft in extraordinary detail. The hatch was redesigned so it could be opened rapidly, flammable materials were reduced, wiring and plumbing were improved, and procedures were reconsidered. No crewed Apollo spacecraft flew for nearly twenty-one months. Then, in October 1968, Apollo 7 carried Wally Schirra, Donn Eisele, and Walter Cunningham into Earth orbit. The redesigned command and service module worked well. We were flying again.

Yuri Gagarin: We were also preparing for the Moon, although our approach was less visible. The Soviet Union developed the Zond spacecraft, based on Soyuz, for flights around the Moon. In September 1968, Zond 5 traveled around the Moon carrying biological specimens, including tortoises, and returned to Earth. It became the first spacecraft to carry Earth life around the Moon and safely return it. The Americans had reason to wonder whether Soviet cosmonauts might soon follow.

I Would Not See the Finish

Yuri Gagarin: I wanted very much to return to space. After my 1961 flight, I continued training and became involved with the cosmonaut program. But on March 27, 1968, I flew a MiG-15UTI training aircraft with Vladimir Seryogin. Our aircraft crashed near Kirzhach, killing us both. I was thirty-four. I had been the first human in space, but I would never see a human reach the Moon.

Neil Armstrong: Yuri's death was another reminder that astronauts and cosmonauts were also pilots, and aviation itself remained dangerous. By late 1968, however, NASA faced a remarkable possibility. Intelligence and public evidence suggested that the Soviets were working toward circumlunar missions, while our lunar module was not yet ready for a crewed test. NASA made a bold decision: Apollo 8 would go to the Moon without the lunar module.

Apollo 8 Goes Around the Moon

Neil Armstrong: On December 21, 1968, Frank Borman, Jim Lovell, and Bill Anders lifted aboard the first Saturn V to carry humans. Three days later, they entered lunar orbit. Human beings saw the far side of the Moon directly for the first time. Anders photographed Earth rising above the lunar horizon—the famous Earthrise image—and on Christmas Eve the crew broadcast to hundreds of millions of people on Earth. After ten lunar orbits, they fired their engine and came home safely.

The Final Distance

Yuri Gagarin: Had I lived to see Apollo 8, I would have understood immediately what it meant. In 1961, I had traveled once around Earth. Seven years later, human beings had crossed the enormous distance between Earth and Moon and returned. The competition had accelerated technology at an astonishing pace, but it had demanded lives along the way.

Neil Armstrong: Apollo 8 changed the question confronting us. We had demonstrated that astronauts could reach the Moon, orbit it, and return. Now we needed to land. Grissom, White, Chaffee, Komarov, Gagarin, and others would not see what came next. Their deaths reminded us that progress in space was never inevitable. Every mission depended upon people willing to confront risks, engineers willing to admit failures, and organizations willing to learn from them. By the end of 1968, the Moon was no longer an unreachable destination. It was our next flight.

July 1969 — Apollo 11 and Humanity Walks on the Moon - Told by Neil Armstrong

On the morning of July 16, 1969, Buzz Aldrin, Michael Collins, and I sat atop a Saturn V rocket at Kennedy Space Center. Eight years earlier, President Kennedy had challenged America to land a man on the Moon and return him safely before the decade ended. Since then, Mercury, Gemini, and Apollo had taught us how to survive in space, rendezvous, dock, work outside a spacecraft, and travel to the Moon. Now there were no more practice missions between us and the objective. Apollo 11 was going to attempt the landing.

Seven and a Half Million Pounds of Thrust

At 9:32 that morning, the five enormous F-1 engines beneath the Saturn V came alive. Wernher von Braun's team and thousands of engineers had created a rocket capable of producing roughly 7.5 million pounds of thrust at liftoff. The vehicle rose slowly at first, then accelerated as we climbed. About twelve minutes later, we were in Earth orbit. After checking our systems, the third stage fired again and sent us toward the Moon. Earth began shrinking behind us. The destination ahead was approximately 240,000 miles away.

Three Men, Two Spacecraft

We reached lunar orbit on July 19. Michael Collins remained aboard the command module Columbia while Buzz and I entered the lunar module Eagle. Collins had an essential responsibility: if we returned from the surface, he had to be there so we could dock with him and come home. On July 20, Eagle separated from Columbia and began descending. For the first time, human beings were attempting to land a spacecraft on another world.

The Computer Begins Sounding Alarms

During the descent, our computer suddenly displayed a 1202 alarm. Soon another appeared. We did not immediately know whether the problem was serious enough to abort. In Houston, guidance specialist Steve Bales and others quickly determined that the computer was overloaded but was correctly discarding lower-priority tasks and continuing its essential guidance calculations. Mission Control told us to continue. It was an impressive example of why spaceflight depended upon far more than the astronauts inside the spacecraft.

We Were Heading Toward the Wrong Place

As we descended, I looked through the window and realized that the computer was taking us toward a rough area near West Crater, scattered with rocks large enough to threaten the lunar module. I took semi-manual control and flew Eagle farther across the surface while searching for a safer location. Meanwhile, our remaining fuel continued dropping. Mission Control began calling out the seconds of fuel believed to remain before we would have to consider an abort. This was not the time to admire the scenery.

The Eagle Has Landed

Dust began moving beneath us as the descent engine approached the surface. Then a blue contact light appeared, indicating that one of the probes beneath Eagle's landing legs had touched the Moon. I shut down the engine. We had landed at 20:17 UTC on July 20, with only a small amount of usable descent fuel remaining. I radioed Houston: "Houston, Tranquility Base here. The Eagle has landed." Charlie Duke answered from Mission Control that there were a number of people about to turn blue because they had been holding their breath.

One Small Step

Several hours later, I opened Eagle's hatch and began descending the ladder. A television camera transmitted the scene back to Earth. I stepped from the landing pad onto the lunar surface at 02:56 UTC on July 21 and said, "That's one small step for [a] man, one giant leap for mankind." The surface beneath my boots was covered in a fine powder. Above me was a completely black sky, and in that sky hung Earth—the world from which every human being who had ever lived had come.

Buzz Joins Me on the Moon

Buzz Aldrin descended shortly afterward and described the landscape as "magnificent desolation." We spent about two and a half hours outside Eagle. We photographed the area, collected approximately 47.5 pounds of lunar material, deployed scientific experiments, and planted an American flag. We also left a plaque stating that men from planet Earth had first set foot upon the Moon in July 1969 and that we came "in peace for all mankind." Although Apollo was undeniably part of the Cold War competition, standing there made the achievement seem larger than the rivalry that had helped produce it.

Now We Had to Get Home

Landing was only half the mission. On July 21, Eagle's ascent stage lifted us from the Moon and carried us back into lunar orbit. We rendezvoused and docked with Michael Collins aboard Columbia, transferred ourselves and our samples, and abandoned the lunar module. We then began the long journey toward Earth. On July 24, Columbia entered the atmosphere and splashed down safely in the Pacific Ocean. The entire mission had lasted a little more than eight days.

The Race Reached Its Defining Moment

The United States had achieved Kennedy's goal, and Apollo 11 became the defining victory of the Space Race. But I never regarded the Moon landing as the accomplishment of three men. Roughly 400,000 people had worked on Apollo—engineers, mathematicians, technicians, factory workers, scientists, controllers, administrators, and countless others. The Cold War gave our nations a powerful reason to compete, sometimes at tremendous cost. Yet that competition produced something neither nation could truly own. The first footprints were American, but the Moon made Earth itself look different: one small world hanging in darkness, without visible borders, carrying everyone we had ever known.
