The flight of Apollo 11, the mission chosen to attempt the first lunar landing, was scheduled to launch July 16, 1969. After the success of Apollo 10, it appeared that NASA would indeed keep the promise that John F. Kennedy made eight years earlier.
The crew consisted of an all-veteran, multipurpose group: Commander Neil Armstrong, Command Module Pilot Michael Collins, and Lunar Module (LM) Pilot Buzz Aldrin. For all three, it would be their second time in space.
Armstrong, 38, an Ohio-born naval aviator and test pilot, was among the second group of NASA astronauts. Along with David Scott, he flew aboard Gemini VIII in 1966. Collins, also 38, was born in Rome. The son of a U.S. Army major general, he became an Air Force test pilot before being selected to the third group of NASA astronauts. He, with John Young, was a veteran of Gemini X, which flew in 1966. Aldrin, 39, was an engineer and Air Force pilot who was selected in the third astronaut group; he flew with Jim Lovell on Gemini XII in 1966. The support crew for Apollo 11 included capsule communicators (capcoms) Charlie Duke, Ronald Evans, Ken Mattingly, Bruce McCandless, Harrison Schmitt, and Jack Swigert.
Mission planning went smoothly. Not everyone in NASA was amused by the informal names of the Apollo 10 command and lunar modules — Charlie Brown and Snoopy, respectively — so more serious names were given to the Apollo 11 counterparts: Columbia for the command module and Eagle for the LM. Eagle took its name from the emblem of the United States. Columbia borrowed its name in part from the European historical name for the Americas, and also in a reference to Jules Verne’s 1865 novel, From the Earth to the Moon.
Anticipation for the launch was immense. After years of planning, the Gemini missions, and all of the Apollo mission testing, the big day was finally near.
In the summer of 1969, the decade was rocketing to a close, portraying a far different world from the summer of love in 1967 and the hippie culture of 1968. President Richard Nixon had ordered the first troop withdrawals from Vietnam. Former President Dwight Eisenhower lay in state in the U.S. Capitol. Students overran the administration building at Harvard University to protest the Vietnam War.
The Beatles played their last public concert, on the London rooftop of Apple Records. Led Zeppelin released its first album. Plans came together for Woodstock, to be held in August in New York. Brian Jones of the Rolling Stones drowned in his swimming pool. Blind Faith played its first show in front of a massive crowd in London’s Hyde Park.
And the world’s eyes increasingly turned toward that bright ball of light in the night sky.
This stereoscopic version of the celebrated image of Buzz Aldrin on the Moon’s surface, was created by David Burder.
Wednesday, July 16, 1969, dawned clear and bright at Kennedy Space Center in Florida. Thousands of people crowded along roads, around the public viewing areas, and even far off in other parts of the state to watch the rocket’s towering flame head skyward. Jack King, NASA’s chief of public information, supplied commentary for TV network coverage.
With Armstrong, Aldrin, and Collins secured in the capsule, the mighty Saturn V rocket was slated to lift off from the now-historic launchpad 39A, and the countdown began in the early morning. At 9:32 A.M. EDT, the rocket ignited, and Apollo 11 lurched upward with millions watching. The mission to land on the Moon was underway.
The launch was picture-perfect, and within 12 minutes the craft entered Earth orbit at an altitude of about 100 nautical miles (185 kilometers).
After an orbit and a half, the third-stage engine fired and moved the spacecraft into a trans-lunar injection, sending it toward our celestial neighbor. Some 30 minutes later, the crew performed the maneuver that separated the command/service module from the spent rocket stage and allowed docking with the LM. After the rocket stage was discarded, the command module and the LM headed moonward.
The cruise to the Moon lasted three days, and by July 19, the craft passed close enough to the Moon to fire its propulsion engine, setting it on a course to orbit the Moon. Armstrong, Aldrin, and Collins orbited the Moon 30 times and observed all manner of craters and other formations, paying particular attention to the region where they planned to land, the Sea of Tranquillity. Previous unmanned spacecraft had imaged the area, and it appeared to be a safe landing site because of its flat terrain. The exact position was about 12 miles (19 km) southwest of the crater Sabine D, a 1.5-mile-diameter (2.4 km), dish-shaped welt on the lunar surface that later would be renamed Collins in honor of the command module pilot.

On July 20, operations commenced that would lead to humanity’s first steps on another world. Collins stayed aboard Columbia as Armstrong and Aldrin climbed aboard Eagle and began a descent operation. As the two craft separated, Collins carefully viewed Eagle for any possible signs of physical damage as the lunar lander turned in front of him.
Standing inside the cramped LM, Armstrong and Aldrin frantically checked readings and looked through the craft’s narrow window. As they recognized landmarks, they realized they were seeing them about four seconds ahead of the planned exercise — they were going “long,” and the spacecraft would pass the intended landing site.
As they slowly descended and approached an altitude of about 6,000 feet, two program alarms sounded: The spacecraft computer recognized that it could not accomplish all the checks it should in real time. At Mission Control in Houston, engineers were not overly concerned, and they allowed the descent to continue. Later, NASA computer programming chief Margaret Hamilton wrote that the overload occurred due to a checklist error for the spacecraft preparation, and that the computer automatically ignored lower-priority tasks in order to focus on the descent.
The lunar module Eagle undocks from the command module July 20, 1969, to carry Armstrong and Aldrin to the lunar surface. This is one of a series of images made by Collins from the command module as Eagle rotated.
The command module Columbia hovers over the lunar surface, photographed from Eagle on July 20, 1969. The portion of the Moon visible below lies in the north-central region of the Sea of Fertility.
Peering out from Eagle’s windows, Armstrong and Aldrin could see about a 60°-wide field of the surface, which appeared bright and gray. The pair intended to plant a U.S. flag in the soil and deploy an experiment called the Early Apollo Scientific Experiment Package (EASEP), which would collect various data.
After more than two hours of preparation, at 10:39 P.M. EDT on July 20, Armstrong opened the LM’s hatch and began to squeeze through it. At 10:51 P.M. EDT, Armstrong began climbing down the nine-rung ladder to the surface; a mounted slow-scan TV camera captured his descent.
At 10:56 P.M. EDT, Armstrong stepped onto the lunar surface. Black-and-white TV footage of the event was broadcast to countless millions of homes around the world. As kids at the time, many of our readers surely remember the thrill of staying up late to watch this incredible moment.
In this iconic image, perhaps the most famous from the Apollo program, Buzz Aldrin stands on the Moon, gazing at the checklist taped to his wrist. In his helmet, you see the reflection of the photographer, Neil Armstrong, as well as the lunar module Eagle and Aldrin’s shadow.
Mounted on the LM was an aluminum plaque with icons showing Earth’s hemispheres, the astronauts’ signatures, and a statement from Nixon: “Here men from the planet Earth first set foot upon the Moon, July 1969 A.D. We came in peace for all mankind.”
About six and a half hours after Eagle landed, Armstrong stepped into the powdery lunar surface dust and proclaimed, “That’s one small step for [a] man, one giant leap for mankind.” The “a” wasn’t audible in the transmission, altering Armstrong’s quote in many accounts. Armstrong always maintained he said “for a man,” and the “a” was probably obscured by static.
Armstrong then collected a soil sample. Some 12 minutes later, Aldrin climbed down the ladder and joined his colleague on the surface. The astronauts planted the U.S. flag, described walking around in the light lunar gravity as “easy,” and spoke to Nixon via a telephone-radio hookup from the White House.
The moonwalkers kicked up substantial amounts of dust as they walked around. As they then focused on experiments, they shot photographs, deployed a seismometer, set up a retroreflector, and collected rock samples.
The excursion was to last 34 minutes, but the tasks took longer than expected. So Houston gave them 15 more minutes. Armstrong strolled almost 200 feet from the LM.
But after seven hours of rest, the pair woke up, fired the ascent engine, and lifted off. They reconnected with Collins on Columbia and set a course back to Earth. The crew splashed down in the Pacific Ocean on July 24, returning as worldwide heroes.
The Moon had been conquered. Kennedy’s dream came true. A new era in human history began. And no one was exactly sure where this amazing moment would lead the world next.
