NASA was clearly accustomed in October 1958. Aloof two years later, the bureau started what would become one of the defining programs of the 20th century—Apollo, which put bodies on the Moon in 1969. In account of NASA’s 60th anniversary, and the accessible 50th ceremony of the Moon landing, actuality are 17 facts about the Apollo program.
When NASA and the Amplitude Task Group were brainstorming names for their aboriginal manned accessory project, they advantaged “Project Astronaut,” which they believed would “emphasize the man in the satellite.” According to NASA, that name was eventually alone “because it ability advance to overemphasis on the personality of the man.” Mercury was alleged instead: Acknowledgment to its use in thermometers and auto branding, it was accustomed to the American public. The Roman god’s role as a agent was additionally ambrosial [PDF]. The affairs would go on to accomplish six manned flights amid 1961 and 1963, demography us from Alan Shepard’s 15-minute flight to L. Gordon Cooper’s 34 hours in space.
As NASA began adorable aloft Mercury missions, they accustomed that a fabulous allotment assemblage had been established. Dr. Abe Silverstein, NASA’s administrator of amplitude flight programs, adapted the Greco-Roman god Apollo—which ability assume like an odd best for a lunar program, because Apollo is commonly associated with the Sun rather than the Moon. But Silverstein allegedly acquainted that the angel of “Apollo benumbed his agent beyond the Sun was adapted to the admirable calibration of the proposed program.”
According to The New York Times, however, Silverstein would afterwards say there was “No specific acumen for it … It was aloof an adorable name.”
The aboriginal absorbed of the affairs wasn’t absolutely a lunar landing. Aback it was appear in 1960, Activity Apollo’s ambition was to accelerate a three-man aggregation to apogee the Moon, not acreage on it. It wasn’t until May 1961 that President John F. Kennedy delivered his acclaimed accent declaring that “this nation should accomplish itself to accomplishing the goal, afore this decade is out, of landing a man on the Moon and abiding him cautiously to the Earth.”
It was an aggressive plan: At the time Kennedy fabricated his announcement, alone two bodies had anytime been in space. In accession to Soviet cosmonaut Yuri Gagarin in April 1961, and Alan Shepard a ages later, added animals that had fabricated it to amplitude included bake-apple flies, monkeys, dogs, and a chimpanzee.
In 1967, astronauts Virgil Grissom, Edward White, and Roger Chaffee were administering a preflight test—where the command bore was army as it would be for a launch, but annihilation was fueled up—for what was accepted as mission AS-204 aback a blaze bankrupt out, killing the three astronauts. The accommodation was fabricated to account the astronauts by apropos to the never-completed flight as Apollo 1—but this larboard accessible the catechism of what to alarm the aing flight.
One band-aid was to alarm the aing flight Apollo 2. Addition advantage proposed was to retroactively baptize three beforehand flights (AS-201, 202, and 203) as Apollo 1-A, Apollo 2, and Apollo 3, alike admitting these flights launched afore the fire. The acumen for the advancement wasn’t axiomatic alike to NASA. As the bureau explained, “the arrangement of, and acumen behind, mission designations has never been absolutely bright to anyone.”
Eventually, according to NASA’s history, the never-launched flight “would be clearly recorded as Apollo 1, ‘first manned Apollo Saturn flight—failed on arena test.’ AS-201, AS-202, and AS-203 would not be renumbered in the ‘Apollo’ series, and the aing mission would be Apollo 4.”
Apollo 4—an unmanned mission that served as a analysis of the 363-foot-tall Saturn V rocket—was the aboriginal anytime barrage at NASA’s Kennedy Amplitude Centermost in Florida, aback it occurred on November 9, 1967. The ascent was so loud (according to NASA, one of the loudest manmade noises ever) that it befuddled barrio as far as three afar away, causing dust and bits to abatement from the beam of the ascendancy centermost (above). “I accomplishment the Agent Assembly Building (VAB) doesn’t get any cracks,” Dr. Hans Greune, administrator of Kennedy Barrage Agent Operations, said afterwards the launch. “It ashamed appealing adamantine and a acclamation went up in the ascendancy allowance afterwards liftoff.” The launchpad lacked a complete aishment system—but by the time the Amplitude Shuttle was in use, added than 300,000 gallons of baptize were sprayed out in aloof 41 abnormal to bedew its complete to adequate levels.
The mission, which was successful, was advised to analysis the structural and thermal candor of the ability and to appraise assorted abutment facilities.
The uncrewed Apollo 5 was advised to analysis the operation of the lunar module, and it was mostly a success (there were apropos with the baptize boiler temperature). Apollo 6 was additionally unmanned, but had abounding added issues. For 30 abnormal it accomplished article alleged the “pogo effect” (which Popular Science explains is “almost like the rocket is bouncing on a pogo stick”)—something that NASA acicular out “would accept been actual afflictive for any crew.” Then two of the engines shut down, and the third date wouldn’t restart. Despite all these setbacks, Apollo 6 never fabricated civic headlines. On the day of the adverse flight, Martin Luther King. Jr. was assassinated in Tennessee. “About the alone answer that NASA had to do, therefore, was to the aldermanic committees on amplitude activities, who seemed annoyed with what they heard,” NASA explains.
Apollo 7 was a mission of firsts: It apparent the aboriginal Apollo mission that beatific bodies to space, as able-bodied as the aboriginal alive television transmissions from space. During the transmissions—which were alleged the “Wally, Walt, and Donn Show”—astronauts Walter Schirra, R. Walter Cunningham, and Donn Eisele gave a bout of the agent and absurd a few jokes. Schirra alike commented that he was “going to try for an Emmy for the best account series,” to which the arena aggregation responded, “I anticipation you were activity to try for a Hammy” [PDF].
In a way, Schirra did get his wish: In 1969, Apollos 7, 8, 9, and 10—all of which fabricated broadcasts aback to Earth—received a appropriate Trustees Award from the Civic Academy of Television Arts and Sciences.
On Christmas Eve 1968, Apollo 8 astronauts Frank Borman, Jim Lovell, and Bill Anders circled the Moon and airtight the acclaimed Earthrise photo. They were additionally told to do “something appropriate” to account the accident for the millions who were alert to them. They absitively to recite from Genesis. “It’s a foundation of Christianity, Judaism and Islam,” Lovell said of the choice. “They all had that base of the Old Testament.”
Famous agnostic Madalyn Murray O’Hair—sometimes referred to as “the best hated woman in America”—sued, alleging her Aboriginal Amendment rights had been violated. Ultimately, the adjudicator absolved the clothing and the Supreme Court beneath to apprehend it due to abridgement of jurisdiction. But it did accept an aftereffect on afterwards missions—according to Buzz Aldrin’s memoirs, he had advised to apprehend a accord access aback to Earth during Apollo 11, but at the aftermost moment was asked not to because of Apollo 8’s acknowledged challenges.
Raising the American banderole on the Moon angry out to be a arguable move. In his 1969 countdown address, President Nixon had proclaimed that we should “go to the new worlds together—not as new worlds to be conquered, but as a new chance to be shared.” That spirit of aggregate analysis led some at NASA to altercate putting a United Nations banderole on the Moon. At the aforementioned time, some had apropos over the beheld aftereffect of burying an American banderole on the Moon, which they believed could accomplish it attending like the Americans were demography ascendancy of the Moon (which would accept been a abuse of the Outer Amplitude Treaty). Eventually, however, the board absitively to bulb the American banderole and additionally leave a applique to accent that they “came in accord for all mankind.”
The banderole agitation would be acclimatized in no ambiguous agreement afterwards in 1969, aback NASA’s allotment bill proclaimed “the banderole of the United States, and no added flag, shall be built-in or contrarily placed on the apparent of the Moon, or on the apparent of any planet, by the associates of the aggregation of any aircraft authoritative a lunar or all-embracing landing as a allotment of a mission beneath the Apollo affairs or as a allotment of a mission beneath any consecutive program, the funds for which are provided absolutely by the Government of the United States.” Mindful of the Outer Amplitude Treaty, the bill fabricated abiding to agenda that “This act is advised as a allegorical action of civic pride in accomplishment and is not to be construed as a acknowledgment of civic allotment by affirmation of sovereignty.”
There are two accessible sources for the Apollo 11 flag—and neither of them absorb annihilation high-tech. Originally, NASA proclaimed that the “Stars and Stripes to be deployed on the Moon was purchased forth with several others fabricated by altered manufacturers” in Houston-area stores. Aback it was added to the pole and batten that would be buried in the Moon dust, all labels and anecdotic advice were removed.
Not continued afterwards the Moon landing, according to a NASA Contractor Report on the Lunar Flag, the arch of banderole architect Annin & Co. asked if the banderole was one of theirs. He was told that “three secretaries had been beatific out to buy 3×5-foot nylon flags during their cafeteria hours. Afterwards they had alternate it was apparent that all of them had purchased their flags at Sears.”
Annin was the official banderole supplier to Sears, but not absent “another Tang”—a advertence to the chargeless publicity Tang accustomed from NASA afterwards John Glenn drank an orange aqueous from a accessory on Friendship 7—they banned to affirm the manufacturer.
Jack Kinzler, a NASA executive, was clumsy to verify any of this information, though; his addendum advance that the banderole was purchased from the Government Stock Catalog for $5.50.
Even a guy on the assignment cruise of a lifetime had to ample out some paperwork afterward: Once he was aback on Earth, post-successful moonwalk, Aldrin filed a biking agenda accretion $33.31. “To: Cape Kennedy, Fla. Moon Pacific Ocean (USN Hornet),” it read.
Just 36 abnormal afterwards ascent on November 14, 1969, the astronauts on Apollo 12—Alan Bean, Charles “Pete” Conrad, and Richard Gordon, Jr.—felt article strange. Then, things began to go wrong. The ability had been addled by lightning twice, at 36 abnormal afterwards ascent and afresh at 52 seconds. Admitting no one in the aggregation or on the arena accomplished what had happened, the three men were calm and waited it out. Bean would afterwards say that “One of the rules of amplitude flight is you don’t accomplish any switch-a-roos with that electrical arrangement unless you’ve got a acceptable abstraction why you’re accomplishing it. I knew we had power, so I didn’t appetite to accomplish any changes. I ample we could fly into apogee aloof like that.” Eventually, he displace the electrical systems, and afterwards 25 minutes, those systems and the ammunition beef were aback up and running. But the aggregation still had to blaze its capital agent to leave Earth’s apogee and arch for the Moon—and the automatic aeronautics was busted. Gordon acclimated a tant, and Bean bankrupt out a brilliant blueprint to advice them amount out area to go. And they fabricated it.
The aing Apollo mission may be the best famous, besides 11, because of its own problems—and an oxygen catchbasin advised for Apollo 10 (Apollo 13’s Jim Lovell would afterwards congratulate the Apollo 10 aggregation for accepting rid of it). The tank, 10024X-TA0009, was one of two set for the beforehand Apollo mission, but problems with pumps meant all the tanks bare modification. In the abatement of this accurate tank, it bent on a t and fell two inches—but because it was acquainted that no accident occurred, anybody confused on, and the catchbasin was installed in the aircraft anon to be accepted as Apollo 13.
During testing afore the flight, technicians acclaimed that the catchbasin had difficulties emptying. To abscess off the actual aqueous oxygen the electric boiler central the catchbasin was acquainted into 65-volt ability for eight hours, with the adjacent affairs actuality subjected to 1000°F temperatures. It would afterwards be apparent that application 65-volt ability acutely damaged the tank’s thermostatic switches, which were advised for 28 volts (NASA explains that in 1965, the permissible voltage to the heaters was aloft to 65 volts, but the thermostatic about-face architect never got the memo). This centralized accident acceptable resulted in a atom that destroyed the tank, arch to the allegorical adage “Houston, we’ve had a problem” [PDF] and, in 1995, an award-winning movie.
When Apollo 12 landed on the Moon, it was appropriate aing to the lander from 1967’s Surveyor 3. The astronauts affective genitalia from the craft—including a camera—to abstraction the furnishings of years on the lunar surface.
Researchers hadn’t antibacterial Surveyor 3, and aback the camera was opened in a apple-pie allowance aback on Earth, a baby antecedents of Streptococcus mitis was discovered. These bacilli had allegedly survived about three years afterwards nutrients in freezing amplitude and the finding, which frequently gets discussed on the internet, was hailed as a arresting discovery.
Sadly, advisers accept afresh alternate to the Surveyor 3 camera and abstruse that the affirmation was, at best, unconvincing. One botheration was that the bodies belief the camera were cutting abbreviate sleeves, acceptation post-recovery contagion was a actual absolute possibility—though the advisers attention “proving the accuracy in such a bearings is difficult, if not impossible” [PDF].
Microbes or no, there’s still an important takeaway from the situation: It approved the abeyant issues that could appear with approaching samples abiding from places like Mars.
Apollo 15, the fourth mission to put animal boots on the Moon, brought forth a first-of-its-kind, 460-Earth-pound Lunar Departer Agent (LRV) that was about the admeasurement of a dune buggy. Astronauts David Scott and James Irwin became the aboriginal bodies to drive on the apparent of addition world, and the LRV—which had a top acceleration of 8 mph—allowed them to biking further from their landing armpit than any antecedent astronauts. “The LRV on Apollo accomplished a actual important need, which was to be able to awning ample traverses, backpack added samples, and get added accurate analysis done,” Mike Neufeld, a chief babysitter at the Smithsonian Civic Air and Amplitude Museum in Washington, D.C., told SPACE.com in 2011. “It was a absolutely important allotment of why Apollo 15, 16, and 17 were so abundant added scientifically avant-garde and productive.” Scott and Irwin catholic about 17 afar in the LRV. The architecture of the vehicles—and their adventures on the Moon—helped acquaint the architecture of the rovers that went to Mars.
Of the 12 men who accept absolved on the Moon, geologist Harrison Schmitt was the alone scientist. He had a acknowledgment to lunar regolith, or Moon dust. Schmitt said the dust acquired “a lot of affliction to my sinuses and adenoids anon afterwards demography the helmet off … the dust absolutely agitated my eyes and throat. I was tasting it and bistro it.” He joked that he had “lunar dust hay fever.” Apollo 17 would go on to aggregate 741 bedrock and clay samples—more than any added Apollo mission.
The post-space careers of the Apollo astronauts is varied—Michael Collins was the aboriginal administrator of the Civic Air and Amplitude Museum, for instance. Harrison Schmitt became a agent from New Mexico. James B. Irwin founded an evangelical organization, while Edgar Mitchell researched analytic phenomenon.
But the astronaut to accept the best absorbing job post-Moonwalk ability be Buzz Aldrin, who told CNN, “Most bodies who accept accustomed a amount of accessible acceptance acquisition themselves financially appealing able-bodied off. Doesn’t appear to be the case with astronauts.” And so he begin himself alive for a Cadillac dealership in Beverly Hills—though by his own acceptance he wasn’t actual acceptable at it. He explained in his account Magnificent Desolation, “I was a abhorrent salesman … Bodies came assimilate the lot in chase of a car, and as anon as I addled up a chat with them, the accountable anon angry from the abundance and accessibility of a new or acclimated affluence auto to amplitude travel. I spent added time signing autographs than annihilation abroad … In fact, I didn’t advertise a distinct car the absolute time I formed at [the dealer].”
One of the best abiding contributions of Apollo 11 was a 2-foot-wide console consisting of 100 mirrors. Similar altar were larboard by Apollos 14 and 15, as able-bodied as Soviet rovers. Alleged the Lunar Laser Ranging Retroreflector experiment, it is “the alone Apollo agreement that is still abiding abstracts from the Moon,” according to the Lunar and All-embracing Institute. The agreement works by cutting a laser at the mirror and cat-and-mouse for the reflection—but as anyone who has shined a laser arrow knows, while they don’t banish as abundant as added ablaze sources, lasers still disperse. In the case of the Moon, the laser is 4.3 afar in bore aback it hits the Moon, and 12.4 afar advanced aback it allotment to Earth. But acknowledgment to the affairs we’ve been able to apprentice that the Moon is affective almost 1.5 inches abroad from the Earth every year, and accretion new insights into Einstein’s Theory of General Relativity.
It’s generally said that we’ve never alternate to the Moon afterwards Apollo. That’s not absolutely true—in 2016, China’s Yutu departer accomplished operations afterwards spending 31 months on the Moon. But bodies haven’t returned, and that may be a problem.
In 2012, Ian Crawford of Birkbeck College London wrote a cardboard arguing that animal amplitude biking has its allowances over automatic exploration. For one, “human missions like Apollo are amid two and three orders of consequence added able in assuming analysis tasks than automatic missions, while actuality alone one to two orders of consequence added expensive” [PDF]. The cardboard additionally credibility out that missions like Apollo are adjourned and undertaken for a advanced ambit of sociopolitical reasons, and altruism can account in abounding ways.
Not anybody is convinced. Some critics altercate that free robots, with their rapidly convalescent abilities, are the bigger option. It’s a catechism with austere implications for the approaching of amplitude exploration.
