Tom Wilson, a simulator instructor, suggested an olive branch in its beak to represent their peaceful mission. If they came in too shallow, the capsule would skip off the atmosphere like a rock on a pond.”. Collins added a lunar background with the Earth in the distance. After one and a half orbits, a second ignition of the S-IVB engine pushed the spacecraft onto its trajectory toward the Moon with the trans-lunar injection (TLI) burn at 16:22:13 UTC. They would remain inside a mobile medical quarantine facility (resembling a modified Airstream trailer) for 21 days before being cleared to return to their families. [201][203], The three astronauts spoke before a joint session of Congress on September 16, 1969. Or it could have been the result of Eagle's pirouette maneuver.[113][114]. Three seconds later, Eagle landed and Armstrong shut the engine down. [53], The Apollo 11 prime crew had none of the close cheerful camaraderie characterized by that of Apollo 12. [51] In early 1969, he accepted a job with the National Aeronautics and Space Council effective August 1969, and announced he would retire as an astronaut at that time. [265], As part of the festival, a projection of the 363-foot (111 m) tall Saturn V rocket was displayed on the east face of the 555-foot (169 m) tall Washington Monument from July 16 through the 20th from 9:30 pm until 11:30 pm (EDT). [237] His team brought parts of two of the five engines to the surface. As he stepped off the ladder onto the lunar surface, Armstrong famously radioed back to Earth, "That's one small step for (a) man, one giant leap for mankind." [95], The ascent stage of LM-5 Eagle arrived at the Kennedy Space Center on January 8, 1969, followed by the descent stage four days later, and CSM-107 Columbia on January 23. The support crew maintained the flight plan, checklists and mission ground rules, and ensured the prime and backup crews were apprised of changes. 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. [211][212], New phrases permeated into the English language. “In what’s become a famous moment,” says Neufeld, “Armstrong took over manual control and began maneuvering the spacecraft forward faster so it would skate over the crater to a clear spot beyond it.”. For Apollo, a third crew of astronauts was added, known as the support crew. [12] The MESA failed to provide a stable work platform and was in shadow, slowing work somewhat. Armstrong then jumped onto the ladder's third rung, and climbed into the LM. During NASA's most famous mission, three men went to the moon, and two men landed on it. Map of Moon showing prospective sites for Apollo 11. [149] Aldrin joined Armstrong on the surface. [170], Eagle rendezvoused with Columbia at 21:24 UTC on July 21, and the two docked at 21:35. 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. Information available to the crew and mission controllers during the landing showed the LM had enough fuel for another 25 seconds of powered flight before an abort without touchdown would have become unsafe,[7][127] but post-mission analysis showed that the real figure was probably closer to 50 seconds. [193][194] Nixon welcomed the astronauts back to Earth. [31], An early and crucial decision was choosing lunar orbit rendezvous over both direct ascent and Earth orbit rendezvous. It's an honor for us to be able to participate here today. [80] A landing just after dawn was chosen to limit the temperature extremes the astronauts would experience. Nixon: Hello, Neil and Buzz. Neil Armstrong and Buzz Aldrin raise the American flag on the moon. And they may well ask, why climb the highest mountain? [7], 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, Tranquility Base here. Later, Lovell's crew was forced to switch places with Alan Shepard's tentative Apollo 13 crew to give Shepard more training time. At 06:30, they headed out to Launch Complex 39. After one swing around the planet, the third-stage J-2 rocket ignited, hurling the Apollo astronauts out of near-Earth orbit and on a trajectory toward the moon. A real-time interactive journey through the first landing on the Moon. He realized that a storm front was headed for the Apollo recovery area. [92] Slayton told Armstrong the plan was to have him leave the spacecraft first, if he agreed. [251] 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. 20 July 17:44 Eagle undocks from Columbia and begins its descent to the Moon’s surface. [14] On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite. [3], 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. The Apollo 11 mission emblem was designed by Collins, who wanted a symbol for "peaceful lunar landing by the United States". But he gave "a crisp West Point salute". [106][5] This was done to avoid the third stage colliding with the spacecraft, the Earth, or the Moon. He was moving rapidly from task to task as time ran out. A look back at coverage from … Eagle was traveling too fast. FACT CHECK: We strive for accuracy and fairness. The Apollo 11 lunar landing module Eagle, with astronauts Neil Armstrong and Buzz Aldrin aboard, is photographed above the moon by crewmate Michael Collins on the Columbia command module during rendezvous operations on July 21, 1969. Watch, listen, and relive the excitement of the Apollo 11 lunar landing as experienced minute-by-minute by the courageous crew of Apollo 11 and Mission Control. [172], On the return to Earth, a bearing at the Guam tracking station failed, potentially preventing communication on the last segment of the Earth return. [90] Reporters wrote in early 1969 that Aldrin would be the first man to walk on the Moon, and Associate Administrator George Mueller told reporters he would be first as well. The third carried photographic equipment, and the fourth carried the decontamination swimmer and the flight surgeon. Minutes later the feed was switched to the more sensitive Parkes radio telescope in Australia. [263][264], The Smithsonian Institute's National Air and Space Museum and NASA sponsored the "Apollo 50 Festival" on the National Mall in Washington DC. 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 a curiosity, and men with a vision for the future. [177], On July 12, with Apollo 11 still on the launch pad, Hornet departed Pearl Harbor for the recovery area in the central Pacific,[178] in the vicinity of 10°36′N 172°24′E / 10.600°N 172.400°E / 10.600; 172.400. How Many Times Has the U.S. Landed on the Moon? [174], The aircraft carrier USS Hornet, under the command of Captain Carl J. Seiberlich,[175] 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. On their recommendation, Rear Admiral Donald C. Davis, commander of Manned Spaceflight Recovery Forces, Pacific, advised NASA to change the recovery area, each man risking their careers. "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? Some large rocks jutted out of the dust cloud, and Armstrong focused on them during his descent so he could determine the spacecraft's speed. [182][183], This altered the flight plan. Having the rendezvous radar on (so 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. [209], Humans walking on the Moon and returning safely to Earth accomplished Kennedy's goal set eight years earlier. [103][98] President Richard Nixon viewed the launch from his office in the White House with his NASA liaison officer, Apollo astronaut Frank Borman. It was revealed in 1989 that the Soviets had tried to send people to the Moon, but were unable due to technological difficulties. [179] 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. [34] This design meant the spacecraft could be launched by a single Saturn V rocket that was then under development. The three-man crew reunited in the CSM, jettisoned the LM for good and set course for home. [246], Armstrong's Hasselblad camera was thought to be lost or left on the Moon surface. 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. [91], For decades, Aldrin believed the final decision was largely driven by the lunar module's hatch location. Relive every moment as it occurred in 1969. At the last minute, with fuel supplies running dangerously low, Armstrong realized that the computer’s auto-landing program was dropping them in the middle of a boulder-strewn crater. We choose to go to the Moon ... We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win, and the others, too. [213] Armstrong's words on the lunar surface also spun off various parodies.[211]. The fine soil was quite slippery. The software's action, in this case, was to eliminate lower priority tasks and re-establish the more important ones. [79], NASA's Apollo Site Selection Board announced five potential landing sites on February 8, 1968. The capsule had to enter the atmosphere at a razor-precise angle. All have subsequently been found on Earth. "[166] Subsequent Apollo missions planted their flags farther from the LM. Neil Armstrong’s celebrated “one small step” was far from the most dangerous maneuver in the effort to send three men to the moon and return them home a week later. The Apollo 11 anniversary prompted the Planetary Society to reassess how much the world's first moon program ultimately cost.. [19] Nearly a month later, on May 5, 1961, Alan Shepard became the first American in space, completing a 15-minute suborbital journey. [81] The landing site had to be close to the lunar equator to minimize the amount of propellant required, clear of obstacles to minimize maneuvering, and flat to simplify the task of the landing radar. [42] In March 1969, Apollo 9 put the lunar module through its paces in Earth orbit,[43] and in May Apollo 10 conducted a "dress rehearsal" in lunar orbit. After firing its engines one last time to enter Earth’s orbit, the Service Module was ditched and the three astronauts braced for re-entry inside the cone-shaped Command Module. [99] Launch operations were partly automated, with 43 programs written in the ATOLL programming language. [124], A light informed Aldrin that at least one of the 67-inch (170 cm) probes hanging from Eagle's footpads had touched the surface a few moments before the landing and he said: "Contact light!" [10] These took longer than expected; three and a half hours instead of two. Want more HISTORY? In July 1962 NASA head James Webb announced that lunar orbit rendezvous would be used[32][33] and that the Apollo spacecraft would have three major 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. [145][146][147], About seven minutes after stepping onto the Moon's surface, Armstrong collected a contingency soil sample using a sample bag on a stick. [56], During Projects Mercury and Gemini, each mission had a prime and a backup crew. “You got a bunch of guys about to turn blue. Lunar dust kicked up by the LM's engine began to impair his ability to determine the spacecraft's motion. After a breathless communication blackout of three minutes, Armstrong signaled a successful reentry and the recovery ships made the first visual contact of the capsule with its parachutes deployed. Along with a technician, he helped Armstrong into the left hand couch at 06:54. 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. “If the Saturn V blew up on or near the launch pad, it would have the force of a small nuclear weapon,” says Neufeld. "[257] On August 7, 2009, an act of Congress awarded the three astronauts a Congressional Gold Medal, the highest civilian award in the United States. NASA’s Apollo 11 documentary from 1969. [162][163] 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. Apollo 11, U.S. spaceflight during which commander Neil Armstrong and lunar module pilot Edwin (“Buzz”) Aldrin, Jr., on July 20, 1969, became the first people to land on the Moon. The problem could have been mascons—concentrations of high mass that could have altered the trajectory. They made the decision to change the flight plan so the commander was the first to egress from the spacecraft. I'm talking to you by telephone from the Oval Room at the White House. During the spacecraft’s second pass around the moon, Mission Commander Armstrong and Lunar Module Pilot Aldrin moved from the CSM into the snug confines of the LM to prepare for detachment, leaving Command Module Pilot Michael Collins to anxiously wait and circle in orbit. The bottom half of the lunar module acted as landing gear, and as a platform from which the top half could launch itself into orbit to meet the command module after the mission was completed. Aldrin, Armstrong and Collins decided the Eagle and the Moon would be in their natural colors, and decided on a blue and gold border. Ralph Morse/The LIFE Picture Collection/Getty Images. A set of original videotape recordings of the Apollo 11 Moon landing that were bought for $217.77 at a government surplus auction by a former NASA intern in … [98], An estimated one million spectators watched the launch of Apollo 11 from the highways and beaches in the vicinity of the launch site. Each time he passed over the suspected lunar landing site, he tried in vain to find the module. The astronauts used Eagle's ascent stage to lift off from the lunar surface and rejoin Collins in the command module. [29] Kennedy again proposed a joint expedition to the Moon in a speech to the United Nations General Assembly on September 20, 1963. [69] After some discussion, the olive branch was moved to the talons. Although it has been said "not since Adam has any human known such solitude",[168] Collins felt very much a part of the mission. A portion of the populace did not give it any attention, and another portion was angered by it.[223]. "[195], After Nixon departed, 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. [150] 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. It also referred to Columbia, a historical name of the United States. Armstrong said, "Yes, that's the way to do it. I just can't tell you how proud we all are of what you have done. The Eagle made a risky landing in a shallow moon crater named the Sea of Tranquility. [102][3], First crewed space mission to land on the Moon, This article is about the 1969 crewed lunar mission. "[112], As the descent began, Armstrong and Aldrin found themselves 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. [156] Two types of rocks were found in the geological samples: basalt and breccia. 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 its last location at Museum of Flight in Seattle from March 16 to September 2, 2019. “I think Armstrong was comfortable,” says Neufeld. The data tapes were used to record all transmitted data (video as well as telemetry) for backup. 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. The First Landing on the Moon. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. The name Snowcone was used for the CM and Haystack was used for the LM in both internal and external communications during early mission planning. The hatch was closed again at 05:11:13. "[172], 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. [192] 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. See a timeline of the entire mission. The command module Columbia went on a tour of the United States, visiting 49 state capitals, the District of Columbia, and Anchorage, Alaska. Next came the “powered descent” of the LM, what Neufeld calls “the most critical and dangerous part of the flight.” After separating from the CSM, Armstrong and Aldrin piloted the 32,000-pound LM for two hours toward the lunar surface. Aldrin was afraid it might topple in front of TV viewers. [105], Saturn V AS-506 launched Apollo 11 on July 16, 1969, at 13:32:00 UTC (9:32:00 EDT). Watch the full episode of Moon Landing: The Lost Tapes. 109:24:15), referring to the mission's Ground Elapsed Time (GET),[278] based on the official launch time of July 16, 1969, 13:32:00 UTC (000:00:00 GET). Apollo 11: US government ‘encouraged by photos’ says El-Baz More than half a century ago, Neil Armstrong and Buzz Aldrin touched down at Tranquility Base, fulfilling President John F Kennedy’s goal and bringing an end to the Space Race. Those included a seismograph for measuring “moonquakes” and the Laser Ranging Retroreflector for measuring the precise distance of the moon from Earth. The original requirement that the site be free of craters had to be relaxed, as no such site was found. [168], One of Collins' first tasks was to identify the lunar module on the ground. 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. [140] 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. “If they came in too steep, they would heat up too fast and spacecraft would burn up. [40] In October 1968, Apollo 7 evaluated the command module in Earth orbit,[41] and in December Apollo 8 tested it in lunar orbit. Flight Director Gene Kranz speculated that it could have resulted from extra air pressure in the docking tunnel. "[151] 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.[152]. A space rendezvous is an orbital maneuver in which two spacecraft navigate through space and meet up. To overcome the Earth’s orbital gravity, NASA required a rocket 100 times more powerful than the Mercury boosters that launched the first American astronaut into orbit in 1961. He cleared the crater and found another patch of level ground. Loping became the preferred method of movement. Finally, Aldrin entered, taking the center couch. [136], Eagle's hatch was opened at 02:39:33. About 30 minutes later, with Collins in the left seat and at the controls, the transposition, docking, and extraction maneuver was performed. They were now 100 feet (30 m) from the surface, with only 90 seconds of propellant remaining. [123], Armstrong found a clear patch of ground and maneuvered the spacecraft towards it.
