  • Hank: Thanks to Hack The Moon for sponsoring this very special episode of

  • SciShow. Go to wehackthemoon.com to learn even more about the Apollo 11 mission.

  • Almost 50 years ago on July 20th, 1969, space exploration changed forever.

  • That day the United States landed the first astronauts on the moon as part of

  • the Apollo 11 Mission.

  • And with that famous one small step, they changed the way we think about our planet

  • and ourselves.

  • Apollo 11 wasn't the first time humans had been to space or anything, that happened

  • in 1961 with a Soviet flight followed shortly by an American one.

  • But space, we didn't even really know what that was until fairly recently.

  • The moon, on the other hand, we've been staring at since we existed.

  • Watching it wander through the sky, chasing or being chased by the Sun, moving

  • through its phases.

  • It is another world -- one that has profound effects on our world and also on

  • our species.

  • There's never been a time in human history when we did not gaze at the moon and

  • wonder.

  • And sending people to walk on the surface of another world --the enormity of that

  • giant leap-- It's something that changed us, something that has inspired us as

  • individuals and as a species ever since.

  • So we wanted to do something special to celebrate.

  • We wanted to ask a pretty bold question because while the whole SciShow team loves

  • Apollo, we couldn't help but wonder--and we hope you won't get too mad at us if we

  • ask, was the Apollo program a bad idea?

  • Many people remember it as this beautiful thing that united the world, but if you

  • really think about it, it kind of seems like..

  • I don't know ridiculous?

  • Only five years passed between when the Soviet Union flung the first satellite

  • into orbit and when President John F.

  • Kennedy said these words,

  • President Kennedy: "We choose to go to the Moon.

  • 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."

  • Hank: A year after that Kennedy was dead and only six years later Neil Armstrong

  • and Buzz Aldrin were standing on another world.

  • In hindsight this looks like a work of genius, but lives were lost and other

  • disasters were only narrowly averted.

  • And if that happened, how far back with those tragedies have pushed space

  • exploration.

  • Ultimately was the risk worth the reward and how many close calls were there,

  • really?

  • These are big questions and ones that you can spend a lot of time thinking about but

  • at the end of the day, we're SciShow.

  • Sitting around in wondering isn't really our thing.

  • So we decided to get to the bottom of it.

  • [ ♪INTRO ]

  • Hank: We realized we weren't gonna get to the bottom of this by looking at

  • peer-reviewed journals.

  • It's pretty subjective stuff.

  • So we decided to talk to experts.

  • And to talk to experts, we have Alexis who has gone all over America to talk to those people.

  • I went to London to talk to one person.

  • Alexis.

  • What do you have for us?

  • Alexis: Yeah, honestly, I think a really good place to start with this is just to

  • know about the politics.

  • If you want to understand why the Apollo program happened, it's important to

  • understand that the political climate of the 1950s and 60s.

  • During this time the United States and the Soviet Union were in the middle of the

  • Cold War which was essentially the showdown between two ideologies.

  • You had the Soviet Union and communism on one hand and the US and capitalism on the

  • other hand.

  • And during this conflict, space became a battleground for these two superpowers to

  • prove which ideology was best.

  • Initially, the Soviet Union was actually winning this race.

  • They launched the first satellite.

  • They sent the first human into space.

  • And in the US, people were concerned that these achievements would cause the public

  • to believe that communism was the better option which the US was just not okay with.

  • So that's when the moon became the goal.

  • Ultimately the United States wanted to be the first to send someone to the Moon to

  • prove how great capitalism was.

  • And the Soviet Union wanted to do it to prove the same thing about communism.

  • So even if most people today remember Apollo as a primarily scientific program, it wasn't.

  • In the beginning, it was mainly about proving a political point.

  • Margaret Weitekamp: The Apollo program came with a lot of risk, political risk.

  • This was a big gamble on a large technology program that was funded and

  • started because they wanted to be able to show it to the world.

  • Brady Haran: The other thing a lot of people would say is we only did it because

  • of politics and the Cold War and a stick it up the Russians and cuz there was this

  • competition going on.

  • And you know what?

  • That's true.

  • Hank: Yeah.

  • Brady Haran: That's completely true.

  • But like I see absolutely nothing wrong with that.

  • Like, that is just the circumstances that it took.

  • The technology had to be in the right place and the political climate, the

  • economic climate all had to align in this very unique way and that's what happened

  • and I don't see anything wrong with that.

  • Yes, Apollo was only made possible because of this unique set of circumstances in

  • this competitive political climate that was created, but you know, I don't think

  • that's a negative.

  • I just think we should kind of be a little bit grateful that it happened because if

  • that if that circumstance hadn't happened, we probably --you're right -- we probably

  • wouldn't have gone to the Moon.

  • There probably wouldn't have been the will to spend that much money and do that.

  • Noah Petro: Apollo scientifically started where science had to fit into the corners

  • as much as they could.

  • The initial plan for Apollo 11 included one astronaut getting out, collecting

  • samples, and getting back in and coming back.

  • And several scientists including Jack Schmitt who at the time was an astronaut

  • and training the other astronauts on what they would do when they got to the moon

  • was able to convince NASA management that, No, no, no, we really need to make the

  • most of this one mission.

  • If Apollo 11 is the only time we go to the Moon, we need to deploy experiments on the Moon.

  • Alexis: It's really interesting to think about because like people pointed out,

  • it's this thing that took all of this time and all of these resources.

  • And it brings up the question of like if there had been no conflict to motivate

  • that when we have bothered?

  • Margaret Weitekamp: If you look at the public opinion polls from the time,

  • especially when you asked a question phrased as, "Do you think it's worth the

  • money that's being spent?"

  • Almost never did you get a majority saying that they were fully in support of the

  • Apollo program.

  • When the missions were actually successful, people recognized in the

  • moment that they were seeing history in the making and they wanted to celebrate

  • that and be some part of that so that I think there's a fundamental disconnect

  • between what you see in public opinion polling in terms of our willingness to

  • revert national resources to this program from a general American interest in the

  • idea that we as Americans are explorers and that space is a part of what we do now.

  • Alexis: So growing up something I heard a lot about Apollo is because it was crammed

  • into this really short time period, you had the situation where engineers were

  • working like eight days a week and 25 hours a day to get this done.

  • What was it actually like working on the program?

  • Bob Sieck: Well, it was, it was high activity, high intensity work and the work

  • weeks, work days were long.

  • And in retrospect I would for those of us that did the operations down here where

  • the spacecraft were assembled, the rockets were assembled, and we processed and

  • launched, and it was about as...

  • A marathon at lasted about seven years.

  • That was pretty much it.

  • Hank: So far, it's feeling like the experts aren't really alleviating my concerns here.

  • We have this sort of politically motivated program that you kind of have to eeck some

  • science out of.

  • It's tremendously costly and it's a huge amount of effort necessary to make it happen.

  • We had people in space but the period of time it took for us to go from one person

  • in space to this giant leap into deep space-- it was so fast.

  • Alexis: You hear people say of just like we worked on Apollo around the clock for

  • seven years or how many years or whatever...

  • You think that was like the best idea, of just like trying to cram that in in such a

  • short time frame like--

  • Destin Sandlin: Deadlines are good.

  • Alexis: Okay.

  • Yeah

  • Destin Sandlin: Yeah, deadlines are good.

  • Like, this video you're making, right?

  • Alexis: Yeah.

  • Destin Sandlin: You got a deadline, don't you?

  • Alexis: Right.

  • Destin Sandlin: Okay, and so it's good to have like we call it popping a chalk line.

  • It's good to have a moment in time, like that's the line.

  • We got to do this by then.

  • Alexis: Yeah.

  • Destin Sandlin: I think it's a good thing to have things like that.

  • Yeah, ultimately.

  • You need if you're going to have a massive engineering program, you have to have a

  • schedule because schedule helps you mitigate different things.

  • Like for example, as an engineer.

  • I can keep working on something forever until it's absolutely perfect.

  • But at some point in time, you have to get it good enough and unless you have a

  • schedule to motivate you to shed all of your uncertainties.

  • You're never going to think it's good enough.

  • Hank: We also don't know very much about space at this point in the '60s.

  • How often are there solar flares that could be completely devastating to a

  • crewed mission?

  • We don't know any of this stuff.

  • It's all guesses.

  • There was so much we didn't know.

  • Alexis: And even as I was talking to people on my trip, they kept bringing up

  • things that I had no idea about.

  • Hank: Of course

  • Alexis: Right, so I talked to you to environmental engineers at Kennedy Space

  • Center and they brought up the fact that during the Apollo program because of all

  • of these things we didn't know, the environment around Kennedy got kind of wrecked.

  • Jacqueline Quinn: You did a little history the US Environmental Protection Agency was

  • established December 2nd of 1970.

  • So there was a year and a half between when we're putting men on the moon and

  • leaving footprints behind and when the regulatory agency started up within the

  • United States, so there's a lot of -- from an environmental perspective, there's a

  • timeline that needs to be understood so that you can understand that, you know,

  • all industries followed regulations, but regulations didn't happen at that point,

  • you know, in 1940, 1950 or 1960.

  • They didn't even begin or come into fruition until 1970 until we'd already put

  • men on the moon.

  • So a lot of our regulations that we do now as protectors and stewards of what you see

  • behind us is different than what we did back in that era.

  • Rosaly Santos: Any industry that use, store, or dispose chemicals in the 50s,

  • 60s, and 70s had some environmental impact that was unforeseen.

  • The Resource Conservation and Recovery Act was enacted in the 1970s which provided

  • some guidance of how to manage the waste from whenever you start using it until you

  • dispose of it.

  • And then the Hazardous Waste amendments was enacted in the 1980s.

  • That provided initiated corrective action for any impact that may have happened in the past.

  • So from then on all the industries were in tune with environmental regulations and

  • they complied with all those new requirements that needed to get done.

  • Hank: Basically what I'm getting from this is that you can't be expected to follow a

  • regulation that doesn't exist.

  • Alexis: Right exactly.

  • That was kind of the point they were trying to make.

  • Like technically we could have sat around for like 10 or 20 years to figure all of

  • this stuff out, but it's like we didn't know what we didn't know and we weren't

  • from a political standpoint -- the Soviet Union probably would have landed on the Moon.

  • Hank: Yeah, but that doesn't explain everything here.

  • Like this was a very rushed engineering project, people died, Apollo 1 happened.

  • Apollo 1 was going to be the first crewed mission of the Apollo program.

  • Crewed by Gus Grissom, Ed White, and Roger Chaffee.

  • On January 27, 1967, during a crewed launch rehearsal, the cabin was

  • pressurized with pure oxygen, higher than atmospheric pressure.

  • After an electrical short nylon in the capsule caught fire and the environment.

  • Because the internal pressure of the capsule was higher than the external

  • pressure of the atmosphere, it was impossible to quickly remove the door and

  • all three astronauts were killed.

  • After the accident, all flights were stopped for 20 months.

  • Alexis: But it's actually possible that Apollo one is the reason the rest of the

  • program didn't go terribly, terribly wrong.

  • Bob Sieck: And there were a number of those close calls and then and then right

  • before our first manned mission on Apollo, the tragedy occured.

  • And everything comes to a stop and you go look at everything you're doing.

  • The first to figure out what happened and and fix that before you get on with the goal.

  • And from a big picture standpoint, and this is not rationalizing to me, the whole

  • purpose of Apollo 1 was to be the first step in getting humans to the Moon.

  • Because of what happened with Apollo 1, we looked at all of our preparation up to

  • that point in time and what everyone said is well, these are the things we got to fix.

  • This is what we really learned from Apollo 1.

  • Margaret Weitekamp: Without the changes that came after Apollo 1, we would not

  • have gotten to the Moon.

  • We were on a path that ultimately would not have worked and that dramatic change

  • cost three lives and people were forever after very aware of the high personal cost

  • because those were people they knew.

  • Those were people they were friends with, they knew their families.

  • They knew their children.

  • So the change that in trajectory there in some ways they did Apollo better starting from 1967.

  • Noah Petro: At the time, it was really important to understand what had happened

  • in the Apollo 1 fire make sure that something like that never happen again,

  • but also that we, you know created a culture of safety acceptance.

  • But at the same time with some risk tolerance too.

  • You know, if we were terrified of any problem happening, we would never have

  • gone back into space, but we do because that's our job and there's things to be

  • learned there.

  • So you take a risk, you weigh what might happen and the mitigations to those things

  • and move forward.

  • Alexis: When I went into all of these interviews, I was like, oh yeah, there is

  • no way we could have done this safely in the length of time that we took to do it.

  • But people kept telling me is like, yes, the Apollo program was risky, but like so is space.

  • The Apollo engineer's built all of these safeguards to try and mitigate as much

  • risk as possible.

  • Bob Sieck: Even though yes, it was fun, but it was serious business and people

  • would often stay over overlapping the next shift coming on board because they wanted

  • to see how well the stuff that they thought they fixed on their shift if it

  • really worked right.

  • And but there was that kind of dedication and passion for the for the effort and we

  • never lost sight of the fact and, this was drilled into us as soon as we came on

  • board, that the crew returning safely from whichever mission your assigned to is the

  • most important thing about your work.

  • Noah Petro: I think the reason that Apollo is so successful is that in their training

  • regimen they went through in excruciating detail all of these potential problems

  • that could crop up and how they would solve them.

  • And we learned that Apollo 13; that when one of the most catastrophic things that

  • could happen in space: you lose oxygen tanks and you lose your power source, oh,

  • well, we know how to fix that.

  • Hank: Apollo 13 nearly ended in disaster 56 hours after takeoff when an electrical

  • short in the cryogenic oxygen tanks resulted in the following call from Apollo

  • 13 to Mission Control.

  • Jim Lovell: "Uh, Houston, we've had a problem.

  • We've had a main B bus undervolt."

  • Mission Control: "Roger, main B undervolt.

  • Okay stand by 13, we're looking at it."

  • Fred Haise: "Okay.

  • Right now, Houston, the

  • voltage is -- is looking good.

  • And we had a pretty large bang associated with the caution and warning there."

  • Hank: The pretty large bang in question eventually resulted in a loss of all the

  • oxygen in the Command Module.

  • That meant no oxygen to breathe, no water to drink, and no power for the fuel cells.

  • After some significant engineering challenges were overcome, the astronauts

  • rode out the majority of the mission in the lunar lander.

  • And though they were not able to land on the moon, everyone did at least return

  • home safely.

  • Noah Petro: Apollo 11, they left the lunar module operating after they left the Moon.

  • It was in lunar orbit.

  • They left it operating to basically see how long past its design life.

  • It could go and that informed what they did on Apollo 13.

  • So, you know, there was this entire culture of maximizing what you had to

  • learn what you could do in the event of both success and in the case of something

  • going wrong.

  • If you listen to the the tapes of launch of Apollo 11 or any of the missions

  • they're always reporting out, "okay, you know, we're in mode 1 Bravo were in what

  • abort sequence.."

  • You know, it wasn't up the moment the rocket launch, we're on our way to the Moon.

  • The moment the rocket launched is okay if something happens wrong now, How do we get out of it?

  • And that happens throughout the whole breadth of Apollo even by Apollo 17, the

  • time they're getting ready to lift off, they had checklists and sequences they

  • could do if the rocket didn't ignite the first time.

  • The idea that something wouldn't work as planned was so deeply embedded in

  • everything that was done in Apollo, that I don't know that there was time to stop and

  • think, "well actually, what would happen if.."

  • "Well, if the rocket doesn't launch, we'll do this and then we'll do this and we'll do...

  • "They all had, there was solutions to every potential problem.

  • Hank: So the thing that maybe we've all heard that the Apollo Astronauts were just

  • a bunch of cowboys in space might not be quite accurate.

  • Alexis: Yeah.

  • I feel like that problem comes up when you really only focus on the astronauts.

  • There was a group of guys who were really risk tolerant and really well acquainted with risk.

  • But when you look at the engineers and the people who built this program, that wasn't

  • really the case.

  • The thing is, though, the people I talked to weren't arguing that there was no risk.

  • Hank: Right

  • Alexis: They pointed out that space is just really risky.

  • So when I ask them like if we could have done Apollo better or safer.

  • They had some really interesting answers.

  • Noah Petro: There were risks involved and you know, all of the astronauts all the

  • people part of it realize that exploration has inherent risks and you're going

  • whether you're trying to climb the highest mountain or swim across an ocean or do whatever.

  • You're taking risks and you always want to minimize the hazards that are involved but

  • there is hazards involved.

  • I think exploration has inherent risks in it.

  • Margaret Weitekamp: Anytime you're doing human spaceflight, there's a lot of risk

  • because you're putting a life at stake.

  • And the human in the technological equation is the only part that you really

  • can't re-engineer or perfect.

  • So.

  • Humans like a very narrow temperature spectrum, we get too cold very easily, we

  • get too hot very easily.

  • We human beings don't like to be shaken very hard or it gets very hard for them to function.

  • They need to eat.

  • As they breathe, they foul their own are so you need to keep replenishing that.

  • So the human factor is a tremendous risk, if you will, in putting this together,

  • this is also happening in a moment when there weren't really computer smaller than a room.

  • There weren't really ways of taking photographs without physical film which

  • meant you had to carry it there and carry it back.

  • The kind of uncrewed robotic exploration that starts in the 1970s, going to other

  • planets, putting landers on other planets, wasn't possible in the mid-1960s.

  • Destin Sandlin: These astronauts, they know the risk.

  • Alexis: Yeah.

  • Destin Sandlin: I mean they know there's a chance of death and they sign up for it.

  • Some people have always been willing to accept a higher level of risk to make a

  • better life for others that aren't willing to do that.

  • Hank: Throughout the course of this episode.

  • We've said a lot about risk, but it's worth remembering that there's still so

  • many stories.

  • We could not dive into like the story of the Apollo guidance computer.

  • For context computers before Apollo were mostly made with tiny switches called

  • transistors connected by a bunch of wires, but that could get bulky and computers

  • often filled large rooms.

  • So that had to change if we were going to fly to the moon.

  • Listen to what these engineers had to say.

  • John Miller, Draper Engineer: The guidance computer was really an advance.

  • And the only way to get the weight and the size down was to go to integrated circuits.

  • That's something that hadn't been done before.

  • George Schmidt, Draper Flight Simulation Team: I've heard that at one time we were

  • testing one-third of all integrated circuits that were being manufactured in

  • the United States.

  • Hank: Integrated circuits combined transistors and wires on a small piece of

  • silicon, making them more durable and much lighter.

  • While it took a lot of testing to get them ready, it all worked out.

  • These interviews came from Engineers who worked at the MIT instrumentation lab and

  • now called Draper during the Apollo program.

  • Draper played a major role in the program and was among other things responsible for

  • developing the navigation and guidance system including the first digital flight

  • computer that navigated the astronauts to the moon and back.

  • To celebrate the 50th anniversary of the Apollo 11 Landing, they've created a

  • website called Hack the Moon which explores the technology behind the

  • missions and features imagery and interviews of many of the people who made it possible.

  • In the rest of this video we're going to talk more about whether or not the risks

  • we took with Apollo we're worth it.

  • But if you want to learn more about the people behind the missions when we're

  • done, you can head over to hack the moon's website at we hackthemoon.com.

  • Now, more about those risks.

  • So you take all these risks you do the thing.

  • What do we get from it?

  • Alexis: A lot.

  • Which, thank goodness.

  • That's my non-risk tolerance speaking.

  • Thank goodness it was worth it.

  • Hank: Yeah.

  • Alexis: Yeah, you get a lot from it.

  • We've talked about this a lot on various SciShow Space episodes, but we learned

  • more about what space is like, what the human body does in space, we learned about the moon.

  • Noah Petro: Subsequent Apollo missions had something called the ALSEP the Apollo

  • Lunar Surface Experiments Package.

  • That wasn't going to be ready for Apollo 11, but Jack Schmitt was able to convince

  • NASA basically that, "No, let's just deploy a very simple experiment that only

  • one astronaut needs to deploy.

  • Take about 20 minutes, set it up and make very basic measurements at the time that

  • the the idea was the only measurements that we would want to make our the

  • fundamentals of what the lunar seismicity like and deploy a retroreflector, a mirror

  • on the surface that we could laze to from the earth, that we still used to this day,

  • 50 years later now.

  • First samples that came back from Apollo 11.

  • And it's actually important to remember that Apollo 11 launched on July 16th.

  • Those samples were in a lab in Houston less than two weeks later, you know,

  • that's fast sample return.

  • And so within two weeks of launch, they had those samples and their preliminary

  • examination went on and very soon realize that the moon is very old.

  • Those basalts that they landed on were, you know, well over three and a half

  • billion years old.

  • Also, very dry.

  • There's no water in them.

  • That was the surprise and that they were volcanic and had a lot of titanium and an

  • elements and minerals that we see here on Earth.

  • They also found minerals that had not yet been identified on the earth as well.

  • And so it was this this real discovery of what the moon is made of and how old it is.

  • That was the great unanswered question.

  • I think much of what we do today is informed from Apollo samples, and we're

  • still learning things from the Apollo samples.

  • They were analyzed initially 50 years ago and are still being analyzed today and

  • we're still learning new things from those samples, you know, we didn't learn

  • everything from them 50 years ago when we put them in the safe and walk away.

  • With new instruments and new techniques we learn new things and that informs our

  • understanding of the Moon and by association the rest of the solar system.

  • Margaret Weitekamp: There is a very legitimate argument to be made that all of

  • the money that was spent on the Apollo program was spent on the ground.

  • It created engineering jobs.

  • It created whole communities in Florida, in Alabama.

  • And in fact the federal government as a funder of this big science project was

  • able then to push communities in say the deep south to say you can't be segregated

  • and take Federal funding.

  • You need to find housing for the African American engineers that we want you to be hiring.

  • And so you need to be thinking differently about say race relations.

  • And so in that way the space program is part of that larger push in the 1960s

  • where Federal money is being used not only to fund a technology program, but also to

  • push some social issues.

  • Hank: We did this gigantic thing not to like, you know, get stronger and kill

  • people but to like do a big amazing thing.

  • And it's big, right, like we've been looking at the moon since humans existed

  • and then we walked on it.

  • Alexis: That's weird.

  • Hank: Yeah.

  • Alexis: That's so good.

  • A couple people also said some just like really beautiful poetic things.

  • Hank: Yeah.

  • Margaret Weitekamp: So we just had Jim Lovell here at the museum in December for

  • the anniversary of Apollo 8, which was that famous mission at Christmas time of

  • 1968 where they circled the moon.

  • They went all the way around.

  • In fact, because they were not on a trajectory that was intended to be a

  • practice for a landing, they went farther than any human beings have ever been away

  • from the earth and Lovell talked very persuasively about the earthrise image--

  • that color picture that they took as they came back around the moon and looked back

  • and saw the Earth hanging in shadow, but hanging in space in front of them.

  • And said really, you know, we went to the moon but what we discovered was the Earth,

  • was looking back at ourselves.

  • And it was not a picture that had never been taken before; there had been robotic

  • missions that had taken a picture very much like that.

  • So it was not completely unexpected.

  • But the power of knowing that that image had been taken by a person, by someone

  • like you or me who was behind a camera pushing the shutter and seeing that with

  • his own eyes really was electric.

  • That image ended up on the cover of newspapers across the world and really it

  • begins a kind of much more complex cultural process of us thinking of

  • ourselves as a planet, or starting to imagine and understand who we are all on

  • this little globe together.

  • Brady Haran: What's the point of living longer?

  • And what's the point of having a slightly more comfortable life and just having more

  • heart beats and more days here on Earth, if you don't do things like go to the

  • Moon, if you don't create art, if you don't do amazing things, I don't see why

  • we would want to spend all this money living longer if you don't do great things.

  • I don't think the point of our existence is just to try and prolong our existence.

  • I think the point of our existence is to do great things.

  • And to do amazing things and I think Apollo is one of the real amazing things

  • that humans did.

  • Hank: So count of three was it worth it?

  • 1 2 3.

  • Hank & Alexis: Yes.

  • Hank: So a question I asked Brady was if this was all worth it then can we do it again?

  • Brady Haran: I do find it hard to imagine us doing something as high risk as that

  • now in this kind of era of like health and safety, but I don't think it's just

  • because we live in an era of health and safety.

  • I think it's because we haven't got that same hyper-competitiveness that forces

  • people to take bold risks that, you know, some of these really amazing things that

  • happen: getting to the South Pole, getting to the top of Mount Everest, getting to

  • the Moon come about because humans are scared of being beaten to it.

  • They want it they want to be first and they and they're willing to take risks for that prize.

  • And those top prizes those those prizes that are most sought after, are risky to get to.

  • Because if they weren't someone would have already done it.

  • So I do feel a bit like, you know, at those frontiers,

  • if there's enough competition, people are willing to be a little bit risky.

  • I don't know what will happen with Mars.

  • If it's companies that end up getting their first, if it's the Elon Musks and

  • it's not NASA that gets there first and two or three companies are vying for it.

  • Are they going to take a risk?

  • I don't know, you know, are they going to risk their brand?

  • America kinda risked its brand, didn't it?

  • If they killed a bunch of astronauts, you know?

  • Are companies as willing to take a risk with their brand as a nation that maybe

  • can absorb failure more easily?

  • I don't know.

  • I don't know.

  • It was risky.

  • We don't take those risks now.

  • Will we take those risks, will we take those risks again?

  • I don't know.

  • Alexis: When I talk to other people about it, they actually had a slightly different answer.

  • Noah Petro: You know, Apollo is nothing else.

  • I mean, it was a great accomplishment.

  • It was an incredible achievement, but also showed, you know, what you can do when you

  • have a goal.

  • Apollo: land on the moon, back to Earth in a decade.

  • With a goal of landing humans anywhere in the solar system with a destination and

  • the right data, that can be accomplished.

  • You know, we know more about almost all of the planets in the solar system than we

  • knew certainly 50 years ago.

  • But any object you want to go to today whether it's moon, Mars, an asteroid, we

  • have ample data to accommodate human exploration of any of those destinations.

  • And so it's just a matter of having the prerogative in the the interest in going.

  • Destin Sandlin: I think what's necessary in order to do something huge like this is

  • technical capability.

  • You know, economic ability, you know, money and then a a political will to do it.

  • Right?

  • And so I think we had a unique mixture of all three of those things back in the 60s

  • and we were able to do it.

  • Sputnik just freaked people out.

  • Right?

  • And so at that point it was like, yeah we can do this.

  • So now you get into this risk versus reward discussion, right?

  • And I think we're finally getting to the place now where people realize that space

  • is awesome and we should do things because we should explore.

  • But it's a lot harder because there's no, there's no timeline.

  • Bob Sieck: Today, not only industry but people in general will dwell too much on

  • the, well, yeah, but what if we don't succeed in this.

  • We can't accept you know stuff not working or having a tragedy or an accident.

  • We don't want to, you know, we don't want to have to deal with that.

  • So as a result, let's not do it.

  • Alexis: Mmm.

  • Bob Sieck: Take the easy way out.

  • Financial standpoint: why should we invest a lot of money in this and the project may

  • have to come to, you know, have to be cut off because we didn't make the progress we

  • wanted in the amount of time.

  • We don't want to take that risk.

  • So since we don't want to take the risk, don't even try.

  • Alexis: Yeah.

  • Bob Sieck: And I think that's bad for our society.

  • There's a difference between analyzing and accepting a risk as opposed to gambling.

  • I'm not a gambler.

  • I would never propose we gamble on making the decision to spend this much money for

  • this program or whatever but look at the risk.

  • Look at the benefit, assess it and you know, if the goal is worth the risk, don't

  • worry about it.

  • Just go do it.

  • Hank: From the beginning I wasn't coming at this question as like was it worth it

  • to go to the moon.

  • It's was it the right way to do it.

  • Was it too risky?

  • If things had gone wrong, how much would that have set us back and after these

  • conversations that, mostly you had, I'm starting to feel like this might have been

  • the only time we could have done it.

  • Alexis: Yeah, like if you fast forward even 10, 20, 30 years...

  • Did that perfect storm of conditions exist?

  • Kind of not.

  • And Interesting to think about too is when I talk to people they had said, you know,

  • you need that timeline and that motivation but at least in the US, if we were going

  • to do something like Apollo again through NASA, that's under the control of the

  • executive branch.

  • So it's like, if a president comes in, wants one thing and the next person in

  • office wants something else...

  • Hank: Doesn't want to be just sort of enacting the previous president's vision.

  • Alexis: Right.

  • Hank: Which makes you think like, John F.

  • Kennedy having that mission unfulfilled not just because he was voted out of

  • office but because he was assassinated, like we have to sort of like come together

  • to try and have that vision be completed.

  • Alexis: Yeah.

  • Hank: So Apollo was a good idea.

  • It was just a hard one.

  • Which doesn't mean it's bad.

  • Alexis: Yes.

  • In talking about Apollo, it really makes you think about kind of space exploration

  • in general.

  • Like, if it's risky and it's hard, why do we do it?

  • And there are a lot of reasons for it.

  • Hank: Yeah, and one of those reasons, is because it's hard.

  • Alexis: Yeah, we like to explore things.

  • Hank: Yeah, we like to test our limits.

  • So, there you have it.

  • The Apollo program was one of the most difficult scientific projects of the 20th

  • century, possibly one of the most difficult scientific projects ever, but

  • just because something is hard doesn't mean it's a bad idea.

  • When you remember the full story of Apollo, you start to realize that history

  • is more complicated than you might think and that this achievement would not have

  • been possible without the hundreds or thousands of people supporting it.

  • Thanks to the engineers who work to put these missions together, we were able to

  • go to a place that we had been staring at for Millenia.

  • Not just because we got lucky but because we had a goal and because people worked

  • really hard to achieve it.

  • And honestly, that's pretty encouraging because like some of our experts said, it

  • means that maybe with the right teams and enough perseverance, we could do something

  • like this again.

  • We couldn't have made this episode of scishow without our experts, so thank you

  • to everyone who took the time to talk to us and share your wisdom about the Apollo program.

  • And thank you to Alexis for traveling around and talking to all those very cool people.

  • We also of course could not have tried a big new thing without support from our

  • viewers and from our patrons on Patreon.

  • So thank you so much for watching, your support allows us to take risks, like

  • making a new kind of episode.

  • It was really fun.

  • And we hope you enjoyed it.

  • If you did we have some cool news for you to celebrate Apollo 11 and our new project

  • here, we made mission patches just like the kind that actual astronauts wear.

  • They're very good and you can put them on backpacks or jean jackets or space suits

  • to show your support for Sideshow and Apollo.

  • They'll only be available through the end of July, though, so if you want one, you

  • can click the link in the description.

  • I, for one, am gonna go put it on the backpack right now.
