Mission commander Neil Armstrong and pilot Buzz Aldrin, both American, landed the lunar module Eagle on July 20, 1969, at 20 : 17 UTC. Armstrong became the first person to step onto the lunar surface six hours after landing on July 21 at 02 : 56 : 15 UTC ; Aldrin joined him about 20 minutes later. They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 pounds ( 21.5 kg ) of lunar material to bring back to Earth. Michael Collins piloted the command module Columbia alone in lunar orbit while they were on the Moon 's surface. Armstrong and Aldrin spent 21.5 hours on the lunar surface before rejoining Columbia in lunar orbit. 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 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, and 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 into lunar orbit. Armstrong and Aldrin then moved into Eagle and landed in the Sea of Tranquillity. The astronauts used Eagle 's upper stage to lift off from the lunar surface and rejoin Collins in the command module. They jettisoned Eagle before they performed the maneuvers that blasted them out of lunar orbit on a trajectory back to Earth. They returned to Earth and splashed down in the Pacific Ocean on July 24 after more than eight days in space. The landing was broadcast on live TV to a worldwide audience. Armstrong stepped onto the lunar surface and described the event as `` one small step for ( a ) man, one giant leap for mankind. '' Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by President John F. Kennedy : `` before this decade is out, of landing a man on the Moon and returning him safely to the Earth.

On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite. This surprise success fired fears and imaginations around the world. It not only demonstrated that the Soviet Union had the capability to deliver nuclear weapons over intercontinental distances, it challenged American claims of military, economic and technological superiority. This precipitated the Sputnik crisis, and triggered the Space Race. President Dwight D. Eisenhower responded by creating the National Aeronautics and Space Administration ( NASA ), and initiating Project Mercury, which aimed to launch a man into Earth orbit. But on April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first person in space, and the first to orbit the Earth. It was another body blow to American pride. Nearly a month later, on May 5, 1961, Alan Shepard became the first American in space, completing a 15 - minute suborbital journey. After being recovered from the Atlantic Ocean, he received a congratulatory telephone call from Eisenhower 's successor, John F. Kennedy. Kennedy cared about what people in other nations thought of the United States, and believed that not only was it in the national interest of the United States to be superior to other nations, but that the perception of American power was at least as important as the actuality. It was therefore intolerable that the Soviet Union was more advanced in the field of space exploration. He was determined that the United States should compete, and sought a challenge that maximized its chances of winning. Since the Soviet Union had better booster rockets, he required a challenge that was beyond the capacity of the existing generation of rocketry, one where the US and Soviet Union would be starting from a position of equality. Something spectacular, even if it could not be justified on military, economic or scientific grounds. After consulting with his experts and advisors, he chose such a project. On May 25, 1961, he addressed the United States Congress on `` Urgent National Needs '' and declared : I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important for the long - range exploration of space ; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations - explorations which are particularly important for one purpose which this nation will never overlook : the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the Moon - if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there. The effort to land a man on the Moon already had a name : Project Apollo. An early and crucial decision was the adoption of lunar orbit rendezvous, under which a specialized spacecraft would land on the lunar surface. The Apollo spacecraft therefore had three parts : a command module ( CM ) with a cabin for the three astronauts, and 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. This choice of mode meant that the spacecraft could be launched by the Saturn V rocket that was then under development. Technologies and technics required for Apollo were developed by Project Gemini. Project Apollo was abruptly halted by the Apollo 1 fire on January 27, 1967, in which three astronauts died, and the subsequent investigation. In October 1968, Apollo 7 tested the command module in Earth orbit, and in December, Apollo 8 tested it in lunar orbit. In March 1969, Apollo 9 tested the lunar module in Earth orbit, and then in May 1969, Apollo 10 conducted a `` dress rehearsal '', testing the lunar module in lunar orbit. By July 1969, all was in readiness for Apollo 11 to take the final step onto the Moon. The Soviet Union competed with the US, but were hampered by repeated failures in development of a launcher comparable to the Saturn V. Meanwhile, the Soviets tried to beat the US to return lunar material to the Earth by means of unmanned probes. On July 13, three days before Apollo 11 's launch, the Soviet Union launched Luna 15, which reached lunar orbit before Apollo 11. During descent, a malfunction caused Luna 15 to crash in Mare Crisium about two hours before Armstrong and Aldrin took off from the Moon 's surface to begin their voyage home. The Nuffield Radio Astronomy Laboratories radio telescope in England recorded transmissions from Luna 15 during its descent, and these were released in July 2009 for the 40th anniversary of Apollo 11. Framework Prime crew Position Astronaut Commander Neil A. Armstrong Second and last spaceflight Command Module Pilot Michael Collins Second and last spaceflight Lunar Module Pilot Edwin `` Buzz '' E. Aldrin, Jr. Second and last spaceflight The initial crew assignment of Neil Armstrong as Commander, Jim Lovell as Command Module Pilot ( CMP ) and Buzz Aldrin as Lunar Module Pilot ( LMP ) on the backup crew for Apollo 9 was officially announced on November 20, 1967. Lovell and Aldrin had previously flown together as the crew of Gemini 12. Due to design and manufacturing delays in the Lunar Module ( LM ), Apollo 8 and Apollo 9 swapped prime and backup crews, and Armstrong 's crew became the backup for Apollo 8. Based on the normal crew rotation scheme, Armstrong was then expected to command Apollo 11. There would be one change. Michael Collins, the CMP on the Apollo 8 crew, began experiencing trouble with his legs. Doctors diagnosed the problem as a bony growth between his fifth and sixth vertebrae, requiring surgery. Lovell took his place on the Apollo 8 crew, and, when Collins recovered, he joined Armstrong 's crew as CMP. In the meantime, Fred Haise filled in as backup LMP, and Aldrin as backup CMP for Apollo 8. Apollo 11 was the second all - veteran multi-person crew on an American mission, the first being that of Apollo 10. An all - veteran crew would not be flown again until STS - 26 in 1988. Backup crew Position Astronaut Commander James A. Lovell, Jr. Command Module Pilot William A. Anders Lunar Module Pilot Fred W. Haise, Jr. The backup crew consisted of Lovell as Commander, William Anders as CMP, and Haise as LMP. Anders had flown with Lovell on Apollo 8. In early 1969, he accepted a job with the National Aeronautics and Space Council effective August 1969, and announced that he would retire as an astronaut at that time. Ken Mattingly was moved from the support crew into parallel training with Anders as backup CMP in case Apollo 11 was delayed past its intended July launch date, at which point Anders would be unavailable. Lovell, Haise, and Mattingly were later assigned as the prime crew of Apollo 13. Support crew During Projects Mercury and Gemini, each mission had a prime and a backup crew. For Apollo, a third crew of astronauts was added, known as the support crew. The support crew maintained the flight plan, checklists and mission ground rules, and ensured that the prime and backup crews were apprised of any changes. The support crew developed procedures in the simulators, especially those for emergency situations, so these were ready for when the prime and backup crews came to train in the simulators, allowing them to concentrate on practicing and mastering them. For Apollo 11, the support crew consisted of Ken Mattingly, Ronald Evans and Bill Pogue. Capsule communicators CAPCOM Charles Duke, with backup crewmen Jim Lovell and Fred Haise listening in during Apollo 11 's descent The Capsule communicator ( CAPCOM ) was an astronaut at the Mission Control Center in Houston, Texas, who was the only person who communicated directly with the flight crew. For Apollo 11, the CAPCOMs were : Charles Duke, Ronald Evans, Bruce McCandless II, James Lovell, William Anders, Ken Mattingly, Fred Haise, Don L. Lind, Owen K. Garriott and Harrison Schmitt. Flight directors The four shift flight directors for this mission were : Clifford E. Charlesworth ( Green Team ), launch and extravehicular activity ( EVA ) Gerald D. Griffin ( Gold Team ) Gene Kranz ( White Team ), lunar landing Glynn Lunney ( Black Team ), lunar ascent Call signs After the crew of Apollo 10 named their spacecraft Charlie Brown and Snoopy, assistant manager for public affairs Julian Scheer wrote to Manned Spacecraft Center director George M. Low to suggest the Apollo 11 crew be less flippant in naming their craft. The name Snowcone was used for the Command Module and Haystack was used for the Lunar Module in both internal and external communications during early mission planning. The Command Module was named Columbia after the Columbiad, the giant cannon shell spacecraft fired by a giant cannon ( also from Florida ) in Jules Verne 's 1865 novel From the Earth to the Moon. It also referenced Columbia, a historical name of the United States. The Lunar Module was named Eagle for the national bird of the United States, the bald eagle, which was featured prominently on the mission insignia. Insignia Apollo 11 insignia The Apollo 11 mission emblem was designed by Collins, who wanted a symbol for `` peaceful lunar landing by the United States ''. At Lovell 's suggestion, he chose an eagle as the symbol, put an olive branch in its talons, and drew a lunar background with the Earth in the distance. The sunlight in the image was coming from the wrong direction ; the shadow should have been in the lower part of the Earth instead of the left. NASA officials felt that the talons of the eagle looked too `` warlike '' and after some discussion, the olive branch was moved to the claws. Armstrong was concerned that `` eleven '' would not be understood by non-English speakers, so they went with `` Apollo 11 '' ; they decided not to put their names on the patch, so it would `` be representative of everyone who had worked toward a lunar landing ''. When the Eisenhower dollar coin was released in 1971, the patch design provided the eagle for its reverse side. The design was also used for the smaller Susan B. Anthony dollar unveiled in 1979, ten years after the Apollo 11 mission. Mementos Apollo 11 space - flown silver Robbins medallion Each astronaut had a personal preference kit ( PPK ), a small bag containing personal items of significance that they wanted to take with them on the mission. Neil Armstrong 's PPK contained a piece of wood from the Wright brothers ' 1903 airplane 's left propeller and a piece of fabric from its wing, along with a diamond - studded astronaut pin originally given to Deke Slayton by the widows of the Apollo 1 crew. This pin had been intended to be flown on that mission and given to Slayton afterwards ; but following the disastrous launch pad fire and subsequent funerals, the widows gave the pin to Slayton. Armstrong took it with him on Apollo 11. Site Selection Map of Moon showing prospective sites for Apollo 11. Actual site was site 2. NASA 's Apollo Site Selection Board announced five potential landing sites on February 8, 1968. These were the result of two years ' worth of studies based on high - resolution photography of the lunar surface by the five unmanned probes of the Lunar Orbiter program and information about surface conditions provided by the Surveyor program. The best Earth - bound telescopes could not resolve features with the resolution Project Apollo required. Areas that appeared to be clear and promising on photographs taken on Earth were often found to be totally unacceptable. The original requirement that the site be free of craters had to be relaxed, as no such site was found. The sites were : Site 1 : 34 ° East, 2 ° 40 ' North, in the Sea of Tranquility ( Mare Tranquilitatis ) ; Site 2 : 23 ° 37 ' East, 0 ° 45 ' North, in the Sea of Tranquility ( Mare Tranquilitatis ) ; Site 3 : 1 ° 20 ' West, 0 ° 25 ' North, in the Central Bay ( Sinus Medii ) ; Site 4 : 36 ° 25 ' West, 3 ° 30 ' South, in the Ocean of Storms ( Oceanus Procellarum ) ; and Site 5 : 41 ° 40 ' West, 1 ° 40 ' North, in the Ocean of Storms ( Oceanus Procellarum ). The final site selection was based on seven criteria : The site needed to be smooth, with relatively few craters ; with approach paths free of large hills, tall cliffs or deep craters that might confuse the landing radar and cause it to issue incorrect readings ; reachable with a minimum amount of propellant ; allowing for delays in the launch countdown ; providing the Apollo spacecraft with a free - return trajectory, one that would allow it to coast around the Moon and safely return to Earth without requiring any engine firings should a problem arise on the way to the Moon ; with good visibility during the landing approach, meaning that the Sun would be between 7 and 20 degrees behind the Lunar Module ; and a general slope ( less than 2 degrees ) in the landing area. The requirement for the Sun angle was particularly restrictive, limiting the launch date to one day per month. The Apollo Site Selection Board selected Site 2, with Sites 3 and 5 as backups in the event of the launch being delayed. In May 1969, Apollo 10 flew to within 15 kilometres ( 9.3 mi ) of Site 2, and reported that it was acceptable. Preparations Saturn V SA - 506, the rocket carrying the Apollo 11 spacecraft, heads out of the Vehicle Assembly Building and down to Launch Complex 39 The ascent stage of lunar module LM - 5 arrived at the Kennedy Space Center on January 8, 1969, followed by the descent stage four days later, and Command and Service Module CM - 107 on January, 23. There were several differences between LM - 5 and Apollo 10 's LM - 4 ; LM - 5 had a VHF radio antenna to facilitate communication with the astronauts during their EVA on the lunar surface ; a lighter ascent engine ; more thermal protection on the landing gear ; and a package of scientific experiments known as the Early Apollo Scientific Experiments Package ( EASEP ). The only change in the configuration of the command module was the removal of some insulation from the forward hatch. The command and service modules were mated on January 29, and shipped from the Operations and Checkout Building to the Vehicle Assembly Building on April 14. Meanwhile, the S - IVB third stage of Saturn V AS - 506 had arrived on January 18, followed by the S - II second stage on February 6, S - IC first stage on February 20, and the Saturn V Instrument Unit on February 27. At 1230 on May 20, the 5,443 - tonne ( 5,357 - long - ton ; 6,000 - short - ton ) assembly departed the Vehicle Assembly Building atop the crawler - transporter, bound for Launch Pad 39A, part of Launch Complex 39, while Apollo 10 was still on its way to the Moon. A countdown test commenced on June 26, and concluded on July 2. The launch complex was floodlit on the night of July 15, when the crawler - transporter carried the mobile service structure back to its parking area. In the early hours of the morning, the fuel tanks of the S - II and S - IVB stages were filled with liquid hydrogen. Fueling was completed by three hours before launch. Launch operations were partly automated, with 43 programs written in the ATOLL programming language. Haise entered Columbia about three hours and ten minutes before launch time. Along with a technician, he helped Armstrong into the left hand couch at 06 : 54. Five minutes later, Collins joined him, taking up his position on the right hand couch. Finally, Aldrin entered, taking the center couch. Haise left around two hours and ten minutes before launch. The closeout crew sealed the hatch, and the cabin was purged and pressurized. The closeout crew then left the launch complex about an hour before launch time. The countdown became automated at three minutes and twenty seconds before launch time. Over 450 personnel were at the consoles in the firing room. Mission Launch and flight to lunar orbit Saturn V carrying Apollo 11 rises past the service structure camera An estimated one million spectators watched the launch of Apollo 11 from the highways and beaches vicinity of the launch site. Dignitaries included the Chief of Staff of the United States Army, General William Westmoreland, four cabinet members, 19 state governors, 40 mayors, 60 ambassadors and 200 congressmen. Vice President Spiro Agnew viewed the launch with the former president, Lyndon B. Johnson and his wife Lady Bird Johnson. Around 3,500 media representatives were present. About two - thirds were from the United States ; the rest came from 55 other countries. The launch was televised live in 33 countries, with an estimated 25 million viewers in the United States alone. Millions more around the world listened to radio broadcasts. President Richard Nixon viewed the launch from his office in the White House with his NASA liaison officer, Apollo astronaut Frank Borman. Saturn V AS - 506 launched Apollo 11 on July 16, 1969, at 13 : 32 : 00 UTC ( 9 : 32 : 00 EDT ). It entered Earth orbit at an altitude of 100.4 nautical miles ( 185.9 km ) by 98.9 nautical miles ( 183.2 km ), twelve minutes later. After one and a half orbits, the S - IVB third - stage engine pushed the spacecraft onto its trajectory toward the Moon with the trans - lunar injection ( TLI ) burn at 16 : 22 : 13 UTC. About 30 minutes later, the transposition, docking, and extraction maneuver was performed : this involved separating Columbia from the spent S - IVB stage, turning around, and docking with Eagle still attached to the stage. After the Lunar Module was extracted, the combined spacecraft headed for the Moon, while the rocket stage flew on a trajectory past the Moon. The was done to avoid colliding with the spacecraft, the Earth or the Moon. A slingshot effect from passing around the Moon threw it into an orbit around the Sun. On July 19 at 17 : 21 : 50 UTC, Apollo 11 passed behind the Moon and fired its service propulsion engine to enter lunar orbit. In the thirty orbits that followed, the crew saw passing views of their landing site in the southern Sea of Tranquillity about 12 miles ( 19 km ) southwest of the crater Sabine D. The site was selected in part because it had been characterized as relatively flat and smooth by the automated Ranger 8 and Surveyor 5 landers and the Lunar Orbiter mapping spacecraft and unlikely to present major landing or EVA challenges. It lay about 25 kilometers ( 16 mi ) southeast of the Surveyor 5 landing site, and 68 kilometers ( 42 mi ) southwest of Ranger 8 's crash site. Lunar descent Columbia in lunar orbit, photographed from Eagle At 12 : 52 : 00 UTC on July 20, Aldrin and Armstrong entered Eagle, and began the final preparations for lunar descent. At 17 : 44 : 00 Eagle separated from the Columbia. Collins, alone aboard Columbia, inspected Eagle as it pirouetted before him to ensure the craft was not damaged, and that the landing gear was correctly deployed. Armstrong exclaimed : `` The Eagle has wings ! '' As the descent began, Armstrong and Aldrin found that they were passing landmarks on the surface two or three seconds early, and reported that they were `` long '' ; they would land miles west of their target point. Eagle was traveling too fast. The problem could have been mascons -- concentrations of high mass that could have altered the trajectory. Flight Director Gene Kranz speculated that it could have resulted from extra air pressure in the docking tunnel. Or it could have been the result of Eagle 's pirouette maneuver. Five minutes into the descent burn, and 6,000 feet ( 1,800 m ) above the surface of the Moon, the LM guidance computer ( LGC ) distracted the crew with the first of several unexpected 1201 and 1202 program alarms. Inside Mission Control Center, computer engineer Jack Garman told guidance officer Steve Bales it was safe to continue the descent, and this was relayed to the crew. The program alarms indicated `` executive overflows '', meaning the guidance computer could not complete all of its tasks in real time and had to postpone some of them. Margaret Hamilton, the Director of Apollo Flight Computer Programming at the MIT Charles Stark Draper Laboratory later recalled : To blame the computer for the Apollo 11 problems is like blaming the person who spots a fire and calls the fire department. Actually, the computer was programmed to do more than recognize error conditions. A complete set of recovery programs was incorporated into the software. The software 's action, in this case, was to eliminate lower priority tasks and re-establish the more important ones. The computer, rather than almost forcing an abort, prevented an abort. If the computer had n't recognized this problem and taken recovery action, I doubt if Apollo 11 would have been the successful Moon landing it was. Eagle in lunar orbit photographed from Columbia During the mission, the cause was diagnosed as the rendezvous radar switch being in the wrong position, causing the computer to process data from both the rendezvous and landing radars at the same time. However, software engineer Don Eyles concluded in a 2005 Guidance and Control Conference paper that the problem was actually due to a hardware design bug previously seen during testing of the first unmanned LM in Apollo 5. Having the rendezvous radar on ( so that it was warmed up in case of an emergency landing abort ) should have been irrelevant to the computer, but an electrical phasing mismatch between two parts of the rendezvous radar system could cause the stationary antenna to appear to the computer as dithering back and forth between two positions, depending upon how the hardware randomly powered up. The extra spurious cycle stealing, as the rendezvous radar updated an involuntary counter, caused the computer alarms. The Apollo onboard flight software for both the CM and LM was developed using an asynchronous executive so that higher priority jobs could interrupt lower priority jobs. The sequence that occurred in the Apollo 11 landing was successful because of its global error detection and recovery system. This included the restart capability to `` kill and start over again '' and recompute and the display interface routines ( `` priority displays '' ) providing the ability, in the case of an emergency, to interrupt nominal displays with higher priority alarm displays. Steps previously taken to create solutions that took advantage of this multiprogramming environment suggested solutions for multiprocessing. Although only one process is actively executing at a given time in a multiprogramming environment, other processes in the same system ― sleeping or waiting ― exist in parallel with the executing process. With this as a backdrop, the priority display mechanisms were created, essentially changing the man - machine interface between the astronauts and the onboard flight software from synchronous to asynchronous displays so that a mission could be reconfigured in real time should it become necessary to do so. Landing When Armstrong again looked outside, he saw that the computer 's landing target was in a boulder - strewn area just north and east of a 300 - meter ( 980 ft ) diameter crater ( later determined to be West crater, named for its location in the western part of the originally planned landing ellipse ). Armstrong took semi-automatic control. Play media Landing on the Moon, July 20, 1969 Throughout the descent, Aldrin called out navigation data to Armstrong, who was busy piloting the Eagle. A few moments before the landing, a light informed Aldrin that at least one of the 67 - inch ( 170 cm ) probes hanging from Eagle 's footpads had touched the surface, and he said : `` Contact light ! '' Three seconds later, Eagle landed and Armstrong said `` Shutdown. '' Aldrin immediately said `` Okay, engine stop. ACA -- out of detent. '' Armstrong acknowledged : `` Out of detent. Auto. '' Aldrin continued : `` Mode control -- both auto. Descent engine command override off. Engine arm -- off. 413 is in. '' ACA was the attitude control assembly, the LM 's control stick. Output went to the LGC to command the reaction control system ( RCS ) jets to fire. `` Out of Detent '' meant that the stick had moved away from its centered position ; it was spring - centered like the turn indicator in a car. LGC address 413 contained the variable that indicated that the LM had landed. The Eagle landed at 20 : 17 : 40 UTC on Sunday July 20 with about 25 seconds of fuel left. Apollo 11 landed with less fuel than subsequent missions, and the astronauts encountered a premature low fuel warning. This was later found to be the result of greater propellant ' slosh ' than expected, uncovering a fuel sensor. On subsequent missions, extra anti-slosh baffles were added to the tanks to prevent this. Armstrong acknowledged Aldrin 's completion of the post landing checklist with `` Engine arm is off '', before responding to the CAPCOM, Charles Duke, with the words, `` Houston, Tranquillity Base here. The Eagle has landed. '' Armstrong 's unrehearsed change of call sign from `` Eagle '' to `` Tranquillity Base '' emphasized to listeners that landing was complete and successful. Duke mispronounced his reply as he expressed the relief at Mission Control : `` Roger, Twan -- Tranquillity, we copy you on the ground. You got a bunch of guys about to turn blue. We 're breathing again. Thanks a lot. '' Play media The Apollo 11 landing site visualized in three dimensions using photography and a stereo digital elevation model from the LRO camera. Two and a half hours after landing, before preparations began for the EVA, Aldrin radioed to Earth : This is the LM pilot. I 'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way. He then took communion privately. At this time NASA was still fighting a lawsuit brought by atheist Madalyn Murray O'Hair ( who had objected to the Apollo 8 crew reading from the Book of Genesis ) demanding that their astronauts refrain from broadcasting religious activities while in space. As such, Aldrin chose to refrain from directly mentioning taking communion on the Moon. Aldrin was an elder at the Webster Presbyterian Church, and his communion kit was prepared by the pastor of the church, the Rev. Dean Woodruff. Webster Presbyterian possesses the chalice used on the Moon and commemorates the event each year on the Sunday closest to July 20. The schedule for the mission called for the astronauts to follow the landing with a five - hour sleep period. However, they elected to forgo the sleep period and begin the preparations for the EVA early, thinking that they would be unable to sleep. Lunar surface Operations A photograph of Armstrong taken by Aldrin. This is one of the only few photographs of Armstrong on the lunar surface ; most of the time he had the camera. Preparations for the EVA began at 23 : 43. These took longer than expected ; three and a half hours instead of two. During training on Earth, everything required had been neatly laid out in advance, but on the Moon the cabin contained a large number of other items as well, such as checklists, food packets and tools. Once Armstrong and Aldrin were ready to go outside, Eagle was depressurized. The hatch was opened at 02 : 39 : 33. Armstrong initially had some difficulties squeezing through the hatch with his Portable Life Support System ( PLSS ). Some of the highest heart rates recorded from Apollo astronauts occurred during LM egress and ingress. At 02 : 51 Armstrong began his descent to the lunar surface. The remote control unit controls on his chest kept him from seeing his feet. Climbing down the nine - rung ladder, Armstrong pulled a D - ring to deploy the Modular Equipment Stowage Assembly ( MESA ) folded against Eagle 's side to activate the TV camera. Apollo 11 used slow - scan television ( TV ) incompatible with broadcast TV, so it was displayed on a special monitor and a conventional TV camera viewed this monitor, significantly reducing the quality of the picture. The signal was received at Goldstone in the United States, but with better fidelity by Honeysuckle Creek Tracking Station near Canberra in Australia. Minutes later the feed was switched to the more sensitive Parkes radio telescope in Australia. Despite some technical and weather difficulties, ghostly black and white images of the first lunar EVA were received and broadcast to at least 600 million people on Earth. Although copies of this video in broadcast format were saved and are widely available, recordings of the original slow scan source transmission from the lunar surface were likely destroyed during routine magnetic tape re-use at NASA. The plaque left on the ladder of Eagle That 's one small step... Problems playing this file ? See media help. While still on the ladder, Armstrong uncovered a plaque mounted on the LM descent stage bearing two drawings of Earth ( of the Western and Eastern Hemispheres ), an inscription, and signatures of the astronauts and President Nixon. The inscription read : Here men from the planet Earth first set foot upon the Moon, July 1969 A.D. We came in peace for all mankind. After describing the surface dust as `` very fine - grained '' and `` almost like a powder '', six and a half hours after landing, Armstrong stepped off Eagle 's footpad and declared : `` That 's one small step for ( a ) man, one giant leap for mankind. '' Armstrong intended to say `` That 's one small step for a man '', but the word `` a '' is not audible in the transmission, and thus was not initially reported by most observers of the live broadcast. When later asked about his quote, Armstrong said he believed he said `` for a man '', and subsequent printed versions of the quote included the `` a '' in square brackets. One explanation for the absence may be that his accent caused him to slur the words `` for a '' together ; another is the intermittent nature of the audio and video links to Earth, partly because of storms near Parkes Observatory. More recent digital analysis of the tape claims to reveal the `` a '' may have been spoken but obscured by static. About seven minutes after stepping onto the Moon 's surface, Armstrong collected a contingency soil sample using a sample bag on a stick. He then folded the bag and tucked it into a pocket on his right thigh. This was to guarantee there would be some lunar soil brought back in case an emergency required the astronauts to abandon the EVA and return to the LM. Twelve minutes after the sample was collected, he removed the TV camera from the MESA and made a panoramic sweep, then mounted it on a tripod. The TV camera cable remained partly coiled and presented a tripping hazard throughout the EVA. Still photography was accomplished with a Hasselblad camera which could be operated hand held or mounted on Armstrong 's suit. Aldrin joined Armstrong on the surface. He described the view with the simple phrase : `` Magnificent desolation. '' Armstrong said that moving in the lunar gravity, one - sixth of Earth 's, was `` even perhaps easier than the simulations... It 's absolutely no trouble to walk around. '' Aldrin joined him on the surface and tested methods for moving around, including two - footed kangaroo hops. The PLSS backpack created a tendency to tip backward, but neither astronaut had serious problems maintaining balance. Loping became the preferred method of movement. The astronauts reported that they needed to plan their movements six or seven steps ahead. The fine soil was quite slippery. Aldrin remarked that moving from sunlight into Eagle 's shadow produced no temperature change inside the suit, though the helmet was warmer in sunlight, so he felt cooler in shadow. The MESA failed to provide a stable work platform and was in shadow, slowing work somewhat. As they worked, the moonwalkers kicked up gray dust which soiled the outer part of their suits, the integrated thermal meteoroid garment. Aldrin salutes the deployed United States flag on the lunar surface. The astronauts planted a specially designed U.S. flag on the lunar surface, in clear view of the TV camera. Aldrin remembered, `` Of all the jobs I had to do on the Moon the one I wanted to go the smoothest was the flag raising. '' But the astronauts struggled with the telescoping rod and could only jam the pole a couple of inches into the hard lunar surface. Aldrin was afraid it might topple in front of TV viewers. But he gave `` a crisp West Point salute ''. Before Aldrin could take a photo of Armstrong with the flag, President Richard Nixon spoke to them through a telephone - radio transmission which Nixon called `` the most historic phone call ever made from the White House. '' Nixon originally had a long speech prepared to read during the phone call, but Frank Borman, who was at the White House as a NASA liaison during Apollo 11, convinced Nixon to keep his words brief, to respect the lunar landing as Kennedy 's legacy. Nixon : Hello, Neil and Buzz. I 'm talking to you by telephone from the Oval Room at the White House. And this certainly has to be the most historic telephone call ever made. I just ca n't tell you how proud we all are of what you 've done. For every American, this has to be the proudest day of our lives. And for people all over the world, I am sure they too join with Americans in recognizing what an immense feat this is. Because of what you have done, the heavens have become a part of man 's world. And as you talk to us from the Sea of Tranquillity, it inspires us to redouble our efforts to bring peace and tranquillity to Earth. For one priceless moment in the whole history of man, all the people on this Earth are truly one : one in their pride in what you have done, and one in our prayers that you will return safely to Earth. Armstrong : Thank you, Mr. President. It 's a great honor and privilege for us to be here, representing not only the United States, but men of peace of all nations, and with interest and curiosity, and men with a vision for the future. It 's an honor for us to be able to participate here today. Aldrin bootprint ; part of an experiment to test the properties of the lunar regolith They deployed the EASEP, which included a Passive Seismic Experiment Package used to measure moonquakes and a retroreflector array used for the Lunar Laser Ranging experiment. Then Armstrong walked 196 feet ( 60 m ) from the LM to snap photos at the rim of Little West Crater while Aldrin collected two core samples. He used the geologist 's hammer to pound in the tubes -- the only time the hammer was used on Apollo 11, but was unable to penetrate more than six inches deep. The astronauts then collected rock samples using scoops and tongs on extension handles. Many of the surface activities took longer than expected, so they had to stop documenting sample collection halfway through the allotted 34 minutes. Aldrin shoveled 6 kilograms ( 13 lb ) of soil into the box of rocks in order to pack them in tightly. Three new minerals were discovered in the rock samples collected by the astronauts : armalcolite, tranquillityite, and pyroxferroite. Armalcolite was named after Armstrong, Aldrin, and Collins. All have subsequently been found on Earth. Mission Control used a coded phrase to warn Armstrong that his metabolic rates were high, and that he should slow down. He was moving rapidly from task to task as time ran out. However, as metabolic rates remained generally lower than expected for both astronauts throughout the walk, Mission Control granted the astronauts a 15 - minute extension. In a 2010 interview, Armstrong, who had walked a maximum of 196 feet ( 60 m ) from the LM, explained that NASA limited the first moonwalk 's time and distance because there was no empirical proof of how much cooling water the astronauts ' PLSS backpacks would consume to handle their body heat generation while working on the Moon. Lunar ascent and return Aldrin entered Eagle first. With some difficulty the astronauts lifted film and two sample boxes containing 21.55 kilograms ( 47.5 lb ) of lunar surface material to the LM hatch using a flat cable pulley device called the Lunar Equipment Conveyor ( LEC ). This proved to be an inefficient tool, and later missions preferred to carry equipment and samples up to the LM by hand. Armstrong reminded Aldrin of a bag of memorial items in his sleeve pocket, and Aldrin tossed the bag down. Armstrong then jumped onto the ladder 's third rung, and climbed into the LM. After transferring to LM life support, the explorers lightened the ascent stage for the return to lunar orbit by tossing out their PLSS backpacks, lunar overshoes, an empty Hasselblad camera, and other equipment. They then pressurized the LM and settled down to sleep. Aldrin next to the Passive Seismic Experiment Package with Eagle in the background Nixon 's speech writer William Safire had prepared In Event of Moon Disaster for the President to read on television in the event the Apollo 11 astronauts were stranded on the Moon. The contingency plan originated in a memo from Safire to Nixon 's White House Chief of Staff H.R. Haldeman, in which Safire suggested a protocol the administration might follow in reaction to such a disaster. According to the plan, Mission Control would `` close down communications '' with the LM, and a clergyman would `` commend their souls to the deepest of the deep '' in a public ritual likened to burial at sea. The last line of the prepared text contained an allusion to Rupert Brooke 's First World War poem, `` The Soldier ''. While moving inside the cabin, Aldrin accidentally damaged the circuit breaker that would arm the main engine for lift off from the Moon. There was a concern this would prevent firing the engine, stranding them on the Moon. However, a felt - tip pen was sufficient to activate the switch. Had this not worked, the Lunar Module circuitry could have been reconfigured to allow firing the ascent engine. After more than ​ 21 ⁄ hours on the lunar surface, in addition to the scientific instruments, the astronauts left behind an Apollo 1 mission patch and a memorial bag containing a gold replica of an olive branch as a traditional symbol of peace and a silicon message disk. The disk carries the goodwill statements by Presidents Eisenhower, Kennedy, Johnson, and Nixon and messages from leaders of 73 countries around the world. The disc also carries a listing of the leadership of the US Congress, a listing of members of the four committees of the House and Senate responsible for the NASA legislation, and the names of NASA 's past and present top management. Map showing landing site and photos taken After about seven hours of rest, the crew was awakened by Houston to prepare for the return flight. Two and a half hours later, at 17 : 54 UTC, they lifted off in Eagle 's ascent stage to rejoin Collins aboard Columbia in lunar orbit. Film taken from the LM Ascent Stage upon liftoff from the Moon reveals the American flag, planted some 25 feet ( 8 m ) from the descent stage, whipping violently in the exhaust of the ascent stage engine. Aldrin looked up in time to witness the flag topple : `` The ascent stage of the LM separated... I was concentrating on the computers, and Neil was studying the attitude indicator, but I looked up long enough to see the flag fall over. '' Subsequent Apollo missions usually planted the American flags further from the LM to prevent them being blown over by the ascent engine exhaust. After rendezvous with Columbia, Eagle 's ascent stage was jettisoned into lunar orbit on July 21, 1969, at 23 : 41 UTC. Just before the Apollo 12 flight, it was noted that Eagle was still likely to be orbiting the Moon. Later NASA reports mentioned that Eagle 's orbit had decayed, resulting in it impacting in an `` uncertain location '' on the lunar surface. The location is uncertain because the Eagle ascent stage was not tracked after it was jettisoned, and the lunar gravity field is sufficiently non-uniform to make the orbit of the spacecraft unpredictable after a short time. On July 23, the last night before splashdown, the three astronauts made a television broadcast in which Collins commented :... The Saturn V rocket which put us in orbit is an incredibly complicated piece of machinery, every piece of which worked flawlessly... We have always had confidence that this equipment will work properly. All this is possible only through the blood, sweat, and tears of a number of people... All you see is the three of us, but beneath the surface are thousands and thousands of others, and to all of those, I would like to say, `` Thank you very much. '' Eagle 's ascent stage approaching Columbia Aldrin added : This has been far more than three men on a mission to the Moon ; more, still, than the efforts of a government and industry team ; more, even, than the efforts of one nation. We feel that this stands as a symbol of the insatiable curiosity of all mankind to explore the unknown... Personally, in reflecting on the events of the past several days, a verse from Psalms comes to mind. `` When I consider the heavens, the work of Thy fingers, the Moon and the stars, which Thou hast ordained ; What is man that Thou art mindful of him ? '' Armstrong concluded : The responsibility for this flight lies first with history and with the giants of science who have preceded this effort ; next with the American people, who have, through their will, indicated their desire ; next with four administrations and their Congresses, for implementing that will ; and then, with the agency and industry teams that built our spacecraft, the Saturn, the Columbia, the Eagle, and the little EMU, the spacesuit and backpack that was our small spacecraft out on the lunar surface. We would like to give special thanks to all those Americans who built the spacecraft ; who did the construction, design, the tests, and put their hearts and all their abilities into those craft. To those people tonight, we give a special thank you, and to all the other people that are listening and watching tonight, God bless you. Good night from Apollo 11. On the return to Earth, a bearing at the Guam tracking station failed, potentially preventing communication on the last segment of the Earth return. A regular repair was not possible in the available time but the station director, Charles Force, had his ten - year - old son Greg use his small hands to reach into the housing and pack it with grease. Greg was later thanked by Armstrong. Splashdown and quarantine Columbia floats on the ocean as Navy divers assist in retrieving the astronauts The aircraft carrier USS Hornet, under the command of Captain Carl J. Seiberlich, was selected as the primary recovery ship ( PRS ) for Apollo 11 on June 5, replacing its sister ship, the LPH USS Princeton, which had recovered Apollo 10 on May 26. The Hornet was then at her home port of Long Beach, California. On reaching Pearl Harbor on July 5, Hornet embarked the Sikorsky SH - 3 Sea King helicopters of HS - 4, a unit which specialized in recovery of Apollo spacecraft, specialized divers of UDT Detachment Apollo, a 35 - man NASA recovery team, and about 120 media representatives. To make room, most of Hornet 's air wing was left behind in Long Beach. Special recovery equipment was also loaded, including a boilerplate command module used for training. On July 12, with Apollo 11 still on the launch pad, Hornet departed Pearl Harbor for the recovery area in the central Pacific, in the vicinity of 10 ° 36 ′ N 172 ° 24 ′ E ﻿ / ﻿ 10.600 ° N 172.400 ° E ﻿ / 10.600 ; 172.400. A presidential party consisting of Nixon, Borman, Secretary of State William P. Rogers and National Security Advisor Henry Kissinger flew to Johnston Atoll on Air Force One, then to the command ship USS Arlington in Marine One. After a night on board, they would fly to Hornet in Marine One for a few hours of ceremonies. On arrival on the Hornet, the party was greeted by the Commander - in - Chief, Pacific Command ( CINCPAC ), Admiral John S. McCain Jr., and NASA Administrator Thomas O. Paine, who flew to Hornet from Pago Pago in one of Hornet 's carrier onboard delivery aircraft. Weather satellites were not yet common, but US Air Force Captain Hank Brandli had access to top secret spy satellite images. He realized that a storm front was headed for the Apollo recovery area. Poor visibility was a serious threat to the mission ; if the helicopters could not locate Columbia, the spacecraft, its crew, and its priceless cargo of Moon rocks might be lost. Brandli alerted Navy Captain Willard S. Houston Jr., the commander of the Fleet Weather Center at Pearl Harbor, who had the required security clearance. On their recommendation, Rear Admiral Donald C. Davis, the commander of Manned Spaceflight Recovery Forces, Pacific, advised NASA to change the recovery area. This was done ; a new one was designated, 215 nautical miles ( 398 km ) northeast of the original. This altered the flight plan. A different sequence of computer programs was used, one never before attempted. In a conventional entry, P64 was followed by P67. For a skip - out re-entry, P65 and P66 were employed to handle the exit and entry parts of the skip. In this case, because they were extending the re-entry but not actually skipping out, P66 was not invoked and instead P65 led directly to P67. The crew were also warned that they would not be in a full - lift ( heads - down ) attitude when the entered P67. The first program 's acceleration subjected the astronauts to 6.5 standard gravities ( 64 m / s ) ; the second, to 6.0 standard gravities ( 59 m / s ). Before dawn on July 24, Hornet launched four Sea King helicopters and three Grumman E-1 Tracers. Two of the E-1s were designated as `` air boss '' while the third acted as a communications relay aircraft. Two of the Sea Kings carried divers and recovery equipment. The third carried photographic equipment, and the fourth carried the decontamination swimmer and the flight surgeon. At 16 : 44 UTC ( 05 : 54 local time ) Columbia 's drogue parachutes were deployed. This was observed by the helicopters. Seven minutes later Columbia struck the water forcefully 2,660 km ( 1,440 nmi ) east of Wake Island, 380 km ( 210 nmi ) south of Johnston Atoll, and 24 km ( 13 nmi ) from Hornet, at 13 ° 19 ′ N 169 ° 9 ′ W ﻿ / ﻿ 13.317 ° N 169.150 ° W ﻿ / 13.317 ; - 169.150. During splashdown, Columbia landed upside down but was righted within ten minutes by flotation bags activated by the astronauts. A diver from the Navy helicopter hovering above attached a sea anchor to prevent it from drifting. Additional divers attached flotation collars to stabilize the module and positioned rafts for astronaut extraction. The crew of Apollo 11 in quarantine after returning to Earth, visited by Richard Nixon The divers then passed biological isolation garments ( BIGs ) to the astronauts, and assisted them into the life raft. Though the chance of bringing back pathogens from the lunar surface was considered remote, it was a possibility, and NASA took precautions at the recovery site. Additionally, they were rubbed down with a sodium hypochlorite solution and Columbia wiped with Betadine to remove any lunar dust that might be present. The astronauts were winched on board the recovery helicopter. BIGs were worn until they reached isolation facilities on board the Hornet. The raft containing decontamination materials was intentionally sunk. After touchdown on the Hornet at 17 : 53 UTC, the helicopter was lowered by the elevator into the hangar bay, where the astronauts walked the 30 feet ( 9.1 m ) to the Mobile Quarantine Facility ( MQF ), where they would begin the Earth - based portion of their 21 days of quarantine. This practice would continue for two more Apollo missions, Apollo 12 and Apollo 14, before the Moon was proven to be barren of life, and the quarantine process dropped. Nixon welcomed the astronauts back to Earth. He told them : `` As a result of what you 've done, the world has never been closer together before. '' After Nixon departed, the Hornet was brought alongside the 5 - short - ton ( 4.5 t ) Columbia, which was lifted aboard by the ship 's crane, placed on a dolly and moved next to the MQF. It was then attached to the MQF with a flexible tunnel, allowing the lunar samples, film, data tapes and other items to be removed. Hornet returned to Pearl Harbor, where the MQF was loaded onto a Lockheed C - 141 Starlifter and airlifted to the Manned Spacecraft Center. The astronauts arrived at the Lunar Receiving Laboratory at 10 : 00 UTC on July 28. Columbia was taken to Ford Island for deactivation, and its pyrotechnics made safe. It was then taken to Hickham Air Force Base, from whence it was flown to Houston in a Douglas C - 133 Cargomaster, reaching the Lunar Receiving Laboratory on July 30. In accordance with the Extra-Terrestrial Exposure Law, a set of regulations promulgated by NASA on July 16 to codify its quarantine protocol, the astronauts continued in quarantine. However, after three weeks in confinement ( first in the Apollo spacecraft, then in their trailer on the Hornet, and finally in the Lunar Receiving Laboratory ), the astronauts were given a clean bill of health. On August 10, 1969, the Interagency Committee on Back Contamination met in Atlanta and lifted the quarantine on the astronauts, on those who had joined them in quarantine ( NASA physician William Carpentier and MQF project engineer John Hirasaki ), and on Columbia itself. Loose equipment from the spacecraft remained in isolation until the lunar samples were released for study. Celebrations Ticker tape parade in New York City On August 13, the three astronauts rode in parades in their honor in New York, Chicago, and Los Angeles. On the same evening in Los Angeles there was an official state dinner to celebrate the flight, attended by members of Congress, 44 governors, the Chief Justice of the United States, and ambassadors from 83 nations at the Century Plaza Hotel. Nixon and Agnew honored each astronaut with a presentation of the Presidential Medal of Freedom. This celebration was the beginning of a 45 - day `` Giant Leap '' tour that brought the astronauts to 25 foreign countries and included visits with prominent leaders such as Queen Elizabeth II of the United Kingdom. Many nations honored the first human Moon landing with special features in magazines or by issuing Apollo 11 commemorative postage stamps or coins. On September 16, 1969, the three astronauts spoke before a joint session of Congress. They presented two US flags, one to the House of Representatives and the other to the Senate, that had been carried to the surface of the Moon with them. The flag of American Samoa which was taken to the Moon by Apollo 11 is on display at the Jean P. Haydon Museum in Pago Pago, the capital of American Samoa. Legacy Spacecraft Columbia at the National Air and Space Museum The Command Module Columbia was displayed at the National Air and Space Museum ( NASM ) in Washington, DC. It was in the central Milestones of Flight exhibition hall in front of the Jefferson Drive entrance, sharing the main hall with other pioneering flight vehicles such as the Wright Flyer, the Spirit of St. Louis, the Bell X-1, the North American X-15, and Mercury spacecraft Friendship 7. Armstrong 's and Aldrin 's space suits are displayed in the museum 's Apollo to the Moon exhibit. The quarantine trailer, the flotation collar and the flotation bags are in the Smithsonian 's Steven F. Udvar - Hazy Center annex near Washington Dulles International Airport in Chantilly, Virginia, where they are on display along with a test lunar module. The descent stage of the Lunar Module Eagle remains on the Moon. In 2009, the Lunar Reconnaissance Orbiter ( LRO ) imaged the various Apollo landing sites on the surface of the Moon, for the first time with sufficient resolution to see the descent stages of the lunar modules, scientific instruments, and foot trails made by the astronauts. The remains of the ascent stage lie at an unknown location on the lunar surface, after being abandoned and impacting the Moon. In March 2012 a team of specialists financed by Amazon founder Jeff Bezos located the F - 1 engines from the S - IC stage that launched Apollo 11 into space. They were found below the Atlantic Ocean 's surface through the use of advanced sonar scanning. His team brought parts of two of the five engines to the surface. In July 2013, a conservator discovered a serial number under the rust on one of the engines raised from the Atlantic, which NASA confirmed was from Apollo 11. Columbia was moved in 2017 to the NASM Mary Baker Engen Restoration Hangar at the Steven F. Udvar - Hazy Center in Chantilly, Virginia, to be readied for a four - city tour titled Destination Moon : The Apollo 11 Mission. This included Space Center Houston from October 14, 2017 to March 18, 2018, the Saint Louis Science Center from April 14 to September 3, 2018, the Senator John Heinz History Center in Pittsburgh from September 29, 2018 to February 18, 2019, and the Seattle Museum of Flight from March 16 to September 2, 2019. The Apollo 11 Mobile Quarantine Facility on display at the Steven F. Udvar - Hazy Center in 2009 The S - IVB third stage which performed Apollo 11 's trans - lunar injection remains in a solar orbit near to that of Earth. Moon rocks The main repository for the Apollo Moon rocks is the Lunar Sample Laboratory Facility at the Lyndon B. Johnson Space Center in Houston, Texas. For safekeeping, there is also a smaller collection stored at White Sands Test Facility near Las Cruces, New Mexico. Most of the rocks are stored in nitrogen to keep them free of moisture. They are handled only indirectly, using special tools. Over 100 research laboratories around the world conduct studies of the samples, and approximately 500 samples are prepared and sent to investigators every year. In November 1969, Nixon asked NASA to make up about 250 presentation Apollo 11 lunar sample displays for 135 nations, the fifty states of the United States and its possessions, and the United Nations. Each display included Moon dust from Apollo 11. The rice - sized particles were four small pieces of Moon soil weighing about 50 mg and were enveloped in a clear acrylic button about as big as a United States half dollar coin. This acrylic button magnified the grains of lunar dust. The Apollo 11 lunar sample displays were given out as goodwill gifts by Nixon in 1970. The Passive Seismic Experiment ran until the command uplink failed on August 25, 1969. The downlink failed on December 14, 1969. As of 2018, the Lunar Laser Ranging experiment remains operational. 40th anniversary events Columbia at the Mary Baker Engen Restoration Hangar On July 15, 2009, Life.com released a photo gallery of previously unpublished photos of the astronauts taken by Life photographer Ralph Morse prior to the Apollo 11 launch. From July 16 to 24, 2009, NASA streamed the original mission audio on its website in real time 40 years to the minute after the events occurred. In addition, it is in the process of restoring the video footage and has released a preview of key moments. In July 2010, air - to - ground voice recordings and film footage shot in Mission Control during the Apollo 11 powered descent and landing was re-synchronized and released for the first time. The John F. Kennedy Presidential Library and Museum set up an Adobe Flash website that rebroadcasts the transmissions of Apollo 11 from launch to landing on the Moon. On July 20, 2009, the crew of Armstrong, Aldrin, and Collins met with U.S. President Barack Obama at the White House. `` We expect that there is, as we speak, another generation of kids out there who are looking up at the sky and are going to be the next Armstrong, Collins, and Aldrin '', Obama said. `` We want to make sure that NASA is going to be there for them when they want to take their journey. '' On August 7, 2009, an act of Congress awarded the three astronauts a Congressional Gold Medal, the highest civilian award in the United States. The bill was sponsored by Florida Senator Bill Nelson and Florida Representative Alan Grayson. A group of British scientists interviewed as part of the anniversary events reflected on the significance of the Moon landing : It was carried out in a technically brilliant way with risks taken... that would be inconceivable in the risk - averse world of today... The Apollo programme is arguably the greatest technical achievement of mankind to date... nothing since Apollo has come close ( to ) the excitement that was generated by those astronauts -- Armstrong, Aldrin and the 10 others who followed them.
