This past December 2024, I was on a ship to Antarctica. That's one of my bucket list items. And I couldn't resist because there were some notables on board, and I said this would make a good StarTalk episode. So I snared the one and only William Shatner, Captain Kirk. I don't know if you know, but he is a big fan of exploration. That's not a hard stretch, given...

what he's known for, crossing the universe during the TV commercials using warp drives. But he's also a deep thinker and he loves science. So I had to get him on the program and also on board was NASA astronaut Scott Kelly. You may remember he's a twin with Mark Kelly and both of them have been in space, but Scott Kelly in particular...

was sent into orbit into the International Space Station for 340 days, almost an entire year. He holds the record for continuous time in space for an American. He has a lot to say about exploration and he's a big fan of Shackleton. And let's remember that every explorer who goes where no one has gone before is a risk taker. So if you encounter a challenge where you say, "This might not work, this could be dangerous."

For some people, Captain Kirk included, risk is their business. It's a conversation I'm having with both of them for StarTalk on board a ship to Antarctica. Check it out. Welcome to StarTalk, your place in the universe where science and pop culture collide. StarTalk begins right now.

Scott, we're in the Drake Passage right now. Could you give us a little background on that? Why are we listening? Why are we feel nausea? What's going on here on earth?

Yeah, well, the Drake Passage is the part of the Southern Ocean where at the tip between South America and Antarctica. Cape Horn, the tip. But where the Pacific and the Atlantic Oceans meet, and it's very deep here.

which causes, with the prevailing winds that are generally west to east, some pretty big swells. And I think we're seeing about, I don't know, maybe 14, 15 feet right now, but they can get as high as 50 feet in this passage. - Ooh, so we're in a cruise ship. What would this passage have been like in a wooden ship 100 years ago? - You wouldn't want to do it.

But risk is our business. Yes, I said that Yeah, I think it would be pretty harrowing You know in this kind of even in this sea state and in a ship like that But I can't imagine being at you know swells of 40 and 50 feet I was just talking to my brother on the phone. This is your twin brother twin brother You know when I last interviewed you on StarTalk, I said which brother are you you said you're the good-looking brother I just that's still true

But anyway, he was telling me about being in the North Atlantic on a cargo ship because we were both, when we were younger, training to be merchant mariners in 80-foot seas and losing 20 containers off the ship. So if you think this is bad, just imagine that. So now, Mr. Shatner. My dear. Your show, the original Star Trek series in the 1960s,

was coincident with while we were priming our space program to go to the moon.

And but as far as your show is concerned, we were already there. Space was not a question about whether it should happen. It had already happened. It was a matter of learning to speak Klingon. As many fans of the show managed to. I can't count myself among those who are fluent in Klingon. Nor I. So were you...

Just an actor at the time or did you participate emotionally in this idea that exploration is in our DNA? Exploration doesn't necessarily mean going to Mars and colonizing Mars you can explore

For example, may I spend a moment on exploration and why exploration? A while ago, seven years ago, I heard a story of a ranger in the forest in the Sierras.

uh occupying a cabin and he was there i guess for fire observation and while he was living in the cabin alone uh deer uh came and ate the grass around and then one deer poked his its head in the window to see who was there and and he struck up a conference and had a relationship with the

herd of deer and discovered that deer had posted types of personality there was the diplomat deer who poked his head in to see what was going on there was the guard deer there was a deer you know so these the this herd group had assigned roles that he discovered that my goodness uh that's how we organize ourselves when we were on

The most the last island with the penguins on this voyage, having just returned from Antarctica on this voyage of exploration for all of us, for me, certainly of discovering new worlds, new whatever that whatever the language was and seeing new civilizations, which were the penguins.

And a penguin came up to the group that was standing, having landed. And the penguin...

what are you doing here was that what it was saying this was the diplomat penguin okay and i thought of course this whole thing is a circle of life and and here's a penguin acting like the deer and the ranger and us and this circle i thought wow what an what a discovery of we're in this

Arid land that's rife with life, but you can't see too much of it. But it's there. And the penguins are a big part of it. And it's exploration. And it was a discovery. And I had the best time. Okay, so what you're saying here implicitly and explicitly is that humans aren't the only curious animals out there.

That's right. The penguin was exploring. It was exploring in its own way. No, it was exploring in a very explicit way. What are you guys doing here? You're two-legged. You don't waddle. Some of us waddle, but... You point to me that I waddle. Let's go back 60 years ago. You're an actor. By the way, by the way, I don't know if you knew this, but...

William Shatner appeared in two distinct episodes of the Twilight Zone Yes, and quite memorable episodes at that predating of course the Star Trek series you're an actor in Hollywood. Yeah, and So was there anything in particular that drew you to the part? You're talking about Star Trek. Yeah Star Trek. I was in New York and

doing something in New York and they had made a pilot of Star Trek and NBC didn't want to buy the pilot. They had faults with it, but they loved the idea and they wanted for the first time

I'd never heard of it before. I've never heard of it since. They said, we'll give you another, whatever the cost was, to make another pilot, recast it all. And they called me. I was in New York. They called me. Would I come to Hollywood to see this thing that they had made with the idea of playing the captain? So I was like ushered in. Can I...

presume you had no idea what impact that would have on our culture at the time none whatsoever and i saw the thing that nbc had turned down i thought that's pretty darn good it's a little pedantic it's a little you know here we are or sailing the five oceans but whereas the guys in the capsules are all friendly and you know there isn't this

Distance between the so I suggested a little more Camaraderie and humor and and we sold the pilot. So when I when I look at this By the way, if I don't feel anybody's ever been to comic-con The one at least in San Diego. I don't know if they also do this in New York the very last session is a starship smackdown and

where every single starship, spaceship ever appeared in fictional storytelling is put up on display, like drawings of them, photos of them, and you vote. There are people arguing the case of one ship or another of which is the greatest of ships. The year the Starship Enterprise won that, what carried the day was a simple fact, that no ship before then

ever displayed in storytelling was ever designed to just explore. Every ship you ever see someone get into and out of in a science fiction movie or story, it's designed to take you to a destination. That's why those ships existed. So this as a concept is like, oh my gosh, exploration was paramount.

in why the ship existed at all. Right. It was designed, I mean, what you've said is valid. The truth of the matter is, the designer of the ship had designed many versions.

put them on a wall and invited all the executives in to see which aspect of which drawing they loved. And then he combined what everybody loves. It was like a potpourri of... Oh, I didn't know that. Yeah. NASA's done that before, I think. LAUGHTER

Say that again? - NASA's done that before. That's why they get canceled. - That's the space shuttle. Space shuttle is an amalgam of ideas stapled together pretty much. It's a noble looking ship. It looks like it should go someplace. Unfortunately, it's not powered, right? The space shuttle orbiter, it's got wings and jet nozzles out the back.

So it seems to me, wherever you are, you ought to be able to choose, let's go someplace new. And in fact, that's what they did in the film Armageddon. Yes, but in real life, once they start their approach, they're going to land it. That's one of the reasons why Armageddon

violated more known laws of physics per minute than any other film ever made. So just tell me about the space shuttle, what it meant. If its only job, as fun and versatile as it looked, if its only job was to get you to orbit,

Well, that's not that wasn't his only job. Oh, please. So the space shuttle is one of the most is the most diverse spacecraft we've ever built and probably will be so in our lifetime. But it has one serious limitation. It's heavy and it doesn't carry enough fuel to get out of low Earth orbit.

But it does launch people, it launches cargo, it can build things, it built an International Space Station, it can be its own science laboratory, you can do spacewalks from it. And that cargo bay is huge, as far as I can tell, because it deployed the Hubble Space Telescope, and my favorite size analog to this Hubble Telescope, it's about the size of a Greyhound bus.

which means you could lower a Greyhound bus into the payload of the shuttle. Yeah, something that weighed up to 50,000 pounds, whereas the Soyuz...

If you use that as the counter example, the Russian Soyuz spacecraft is really only designed to launch three people and a very small amount of cargo. And that's it. It does it very well, but it doesn't do very much. You've been up more than once. Have you been up on each of those craft? Twice on each. Twice on each? Yeah. So now maybe because the Soyuz is not as complex...

as the shuttle and the orbiter and the solid rocket boosters, the Soyuz has the best safety record of any space rocket. - They've had two fatal in-flight accidents, just like the space shuttle, but less people. - Okay. - Similar number of flights, but-- - Oh, I thought they had many more flights. Okay, I didn't know that.

Where does this fit with you? We know we learned earlier on this voyage, you gave a marvelous talk reviewing Shackleton, the explorer to the Antarctic and the trials and tribulations he went through and no one died after he got stuck in the ice.

And he's a bit of a hero of yours, as we all felt. And mine too. And yours too. So here's someone who's gone where no one has gone before. Oh, I've heard that. Boldly. Boldly. Boldly gone where no one has gone before. He's right. You sound so good on the track. Is that you narrating it? That was me. Boldly gone. Oh, my God. That was you, though, right? That was me. I'm pretty sure. That was right. With the very famous split infinitive.

A boldly go, go boldly? Yeah. And later in the later films, they said to go boldly. Well, I wrote a book called A Boldly Go. Yeah. No, we love that. When they tried to fix the grammar in a later movie, it was like, no, that's just...

Just deal with it. It doesn't work that way. You were talking about ships and its efficiency. I was invited to the Cape one time. We rolled out the red carpet. So we take Canaveral, Florida. Yeah, where they launch all our spaceships. And in the center of one of those hangars on a platform was the lunar excursion module, the LEMM.

up the stairs and they invited me in to the LEM, which looks like, whatever you call it, you know, the... Pergola? Yes, exactly. It looks... It's the simplest... And you get inside and they have a hammock to lie down on. I laid down on the hammock. And it's this ridiculous children's toy and it's got more instruments, more complications and that's...

The result from the shuttle to the spaceship to the thing and the mud they've got a little garden tool thing to land on the moon get out there take a picture get back in and then Meet up with the whatever we call it the thing circularly module. Well

Then they get out of the LEM into the ship that's going to take them back to Earth. And this, what happens to the, oh, that's been, no, no, what happens to it? Crashes into the moon. It crashes into the moon. Eventually, I guess. However, if memory serves, Apollo 13 realized that for their life support, they needed some of the life support that was on the LEM.

So that in some of the missions subsequent to Apollo 13 didn't they keep the lamb a little further in? Towards earth to make sure is that what happened? I don't remember They used to use life support systems to you know, save themselves the life support systems on the lamb They had to do some modifications, but they were able to use that to you know, safely get back imagine you're getting and they say well What'll we do in the engineers down on earth as they will try this and try that and you're gonna die and

But when you talk about exploration and the means of exploration from the, what's his name, Thor Heidel using papyrus as a raft and then getting to all Shackleton in a wooden boat. And here we are on this modern liner, which was...

being explained by you that the engines here are of particular make and because we don't hear the engines propelling this boat as we are right now going back to Ushuaia, we don't hear the engines. Except every so often, and I didn't understand why, you hear when we're parked, you hear a rumble. I think, what is that? Is that the anchor going down? It's not.

Well, it's station keeping. It's the station keeping. Yeah. So you could drop an anchor, but if you don't need to, then why? Right? And now we know exactly where the boat is. It's not my boat. The captain knows... All the means of exploration going on. The variety of things that we're using to explore. Well, let me throw a little monkey wrench in this. As usual. If...

If you know that much about where you're going and it could be done in the safety and comfort of a luxury ship, then is it really exploration? If the risks have been reduced to zero... Well, what do you mean? If you're rowing in an open boat, you're more exploring than getting a... If you're going where no one has gone before...

That is exploration. All right, if you're attempting tasks that have never been attempted before Scott goes into orbit He's a guinea pig for the doctors on earth because he's got a twin brother We're gonna learn about no one had done that before with a twin brother. It's incredible What an incredible your brother was not the guinea pig you were because you're in space and you're exposed to cosmic rays What happened? What happened to you?

Well, I was exposed to the environment. He was the guinea pig on Earth that was a complete ball of... Yeah, keep telling yourself that. He's chilling on the safety of Earth's surface, and you're not.

And, you know, he had people following him around the country and taking all kinds of samples and having to leave stuff outside his front door. And also was like the lowest stuff outside his front door. We figured what that is. Yeah. For people to pick up lowest, lowest paid government employee at the time because they had to pay him. So he was making minimum wage because he was no longer a NASA astronaut. So I really have to hand it to him to do that. Whereas I was like getting all the glory.

by being in space, but also like you mentioned the radiation. - Yeah, but your heart is smaller than it was when you went in there. - Yeah, stuff happened to you. - Yeah. - It grew back. - It did? - But as my wife Amiko says, it's a good thing I started with a big heart. - That's great. - I just wanna understand this. So even though the exploration was not in the realm of place, it was in the realm of physiology. It's exploratory physiology. - That's exploration. - I agree, I agree, I agree. So what did we learn

By exploring what happens to your body in orbit for how many days? On that mission, 340. 340. They couldn't stay an extra 25 days and call it a year? I wanted to, but the Russians had a certain schedule they had to meet, so we had to come back. Because you came back on the Soyuz. Yeah. Let me remind people, the Soyuz does not land in water. They just land on land. They crash land on the... They crash land. Yeah.

It's really not a landing. Well, if you'll land it, if you walk away, it's a land. It's the ultimate ticket ride when that parachute opens. And if I hated being in space every minute for that entire three hundred forty days, I'd do it all over again for that last 20 minutes.

Really? Just the thrill? The last 20 minutes of coming back to Earth? Yeah. What was that like? Well, when the parachute opens, you just tumble and are thrown around like crazy.

And there have been, I know one of one particular person, I'm sure other people have felt this way, who was an experienced test pilot. I'm not going to say the person's name because I don't want to embarrass them, but he was not, apparently not briefed on how dynamic the landing is. And he started screaming because he thought he was going to die. High pitched or low and guttural?

I wasn't there, yeah. Because there's flames coming out of the tile, right? It's like going over Niagara Falls in a barrel, but while you're on fire. And as soon as you realize... So, I mean, the flames are coming up through the windows. You're on fire. Wait, that's while you're slowing down on... Yeah, but... The chute opens a little bit later. The chute opens later than that. Oh, I understand that. But in that moment, when I was screaming...

Flames are coming up. You're burning up, and you don't know whether the tiles are glued down and up. They may be flipping out. The tiles may be... They lost some tiles. There's a lot of things you don't know that's going on behind the scenes. From the inside, you don't see what's going on on the outside. You might not want to know. What was it like to have three of you in the ship, right? And one guy's going...

Yeah. What's that like? I wasn't there on that one. Oh, you weren't? It was only, you know, reported afterwards that this particular person... Was he... Did they say, you can't do that? I don't know. A lot going on then. You might not... I'm an astronaut and I explore space. I'm going to Mars. But when I came down, I saw flames!

But I still want to get to the bottom of the advancing a space frontier by learning what's happening to your physiology. Oh, yeah. Okay. Let me get back to that. Yeah. Heart shrunk 25%. Changes to my telomeres. 25%. Yeah. Wow. Telomeres, that's like the end of your DNA or something? End of your DNA. Yeah. Really an indication of your physical age. As you get older, they get shorter, more frayed. Initially, NASA thought that was due to the...

controlled diet and exercise. Later, you know, we learned that there were some worms that the Japanese were doing telomere experiments on too. And their telomeres got better while they were on the space station. Never once saw them working out on the treadmill or doing any kind of exercise. So it turns out it was actually the radiation. Most important result?

that I always want everyone to understand and point out is after spending a year in space, like you mentioned earlier, I am now not only smarter, but more handsome than my brother, Mark. - Would he agree to that? - Probably not. - Okay. This idea of pushing the limits of not only what a machine can do, but what human physiology can do, this is exploration. And who, you, sir. - Yes.

Now the oldest person to ascend above the Karman line. - Oh, do we go there again? I am not, my telomeres are very long. - Okay, but let me ask you this. When I saw you go up the ladder,

to go into the space. Into the Blue Origin capsule. Yes, you know, I passed by... And I said, this man is 89 years old. How old were you for that flight? I don't know, 32, something like that. No, times three. Wait a minute. I'm walking up the stairs to go and they're venting. Something's venting out of a pipe. Out of the side of the ship. What's that? Hydrogen. Hydrogen.

- The Zeppelin, the-- - The Hindenburg. - The Hindenburg, burned. And hydrogen was what was burning. - Yeah, and I'm looking at this thing. - Plus there was some coating of aluminum powder on the surface to make it highly reflective. - Exactly. - That burned also on the skin. - The static electricity up the roof. - Had you been in Russia, not only would the thing be venting the fuel, there'd be people smoking cigarettes right at the bottom of the lunch bed.

Let us be candid with ourselves that part of the risk of exploring on some level is even the risk of even starting the trip. If you're exploring, you're ready to die because you're going, at some level, you got to be ready to die. And here you go. What probability of death would you have accepted? What's the highest probability of death you would have accepted to do that mission? To launch on the space shuttle? Yes.

Well, I launched on the space shuttle STS-103 and so we had approximately 103 prior missions and there was one fatal accident, so that's a 1% chance of dying. Yes. What would I have accepted? Certainly not 50%. 10%? Maybe. Maybe 10%. It would depend on what we were doing. Well, that's an interesting question. Yes, it is. Because death is so permanent,

You lose the bet. It's 10 to 1. You don't just pay up. Here's the 100 I owe you. It's your life. 1% is not acceptable. Nothing is acceptable. I'm going up. I'm a test pilot. I've tested this plane. I've tested this thing. I know it works. I'm not going up to die. I'm going to explore. Oof.

That has to be your attitude, right? That has to be your attitude. And that is what you come to terms with. Like, I would think about it leading up to my first flight with, you know, the...

you kind of rationalize hey for one I want to do this I think it's important I want to serve my country it's my job I'm a test pilot there is risk my brother and I used to trade exchange those like death letters for our families like if the thing blows up give this to my you know wife and children and we do that we would do the same fortunately never had to use those but it's you know

Everything is a thing. It's not a thing. Death letters. Maybe I don't know. It was the thing with my brother and I you're a test pilot So you've run that it's a new airplane and you're testing the airplane So you run that airplane along the runway the front now you're a foot up the ground You make a circle and get you 10 feet 20 feet 30 Then you're 50 feet by that time, you know, the plane works you go up to know you knew, you know, it worked and

It might not continue to work as you expand out the envelope. Now you press a button, you eject, I mean, the chances of living. Now, let's go to Mars, guys, okay? Sup, flames, scream, ah, flames! And then finally, you're into orbit and you're going towards Mars. You're going to die. Meteorites, radiation, landing on Mars. This is why we have engineers. You may die.

What? You're not definitely going to die. You may die. It's why we have engineers to figure this out. You're going to die. The chances of you surviving a meteorite hit or lasting six months on Mars with all that radiation and then getting back in and saying, oh, more flames. You've got to get lift off, you know, get out of orbit of, I mean, and land on Earth. You're going to die.

Okay, none of us want to hear you say that, who uttered the words to boldly go in. You're going to die. Boldly go, boldly go to your death. And if you don't die, we'll congratulate you and we'll tell you your telomeres are lengthening. Take us back to Antarctica. There on the open seas.

There could be monsters in the ocean. There could be weather patterns they've never thought of or predicted. They don't know how much food they'll actually need. They don't even know if there will be food there. Devin coined the word katabatic or adabatic. What does that mean? 100-mile-an-hour winds coming downwind or 100-mile-an-hour going up. 100-mile-an-hour winds. You're in a rowboat, for crying out loud. You've got a sail. A sail. A sail's good for 15 knots.

20 knots, you're gonna blow your sails out. 30 knots, your masts are crashing. You're gonna die. So what I have come to learn, being a member of the species that we call Homo sapiens, not all of us fear the risk of death at the same level. Wait a minute. Hang on. No, very simple. There are people who ascend Mount Everest knowing that

There's a real chance they're going to die. They got oxygen. They've got parkas. They're going to slide down on their ass down the glacier to get back to camp. They've got Sherpas who go up without oxygen, run up and run back. If you need some help, sir, I'll help you, says a Sherpa.

They probably give the, you know, all those National Geographic specials where they show someone ascending the mountain for the first time, but there's a camera already there when they get up to the top. So who got the camera? The camera got there first. The Sherpa. The Sherpa and the camera got there first. Exactly. But what I'm saying is, there are people who jump out of airplanes willingly.

People who rock climb. But they have a parachute. They're not going. This thing's going to open. How about that guy that jumped out of, what, he's 50,000? Yeah, Baumgartner. Felix Baumgartner. Who, by the way? He was scared. He was dead. He was not dead. Scared. He was going to die the moment he started twisting. I'm going to die of centrifugal force. How would you like to die of centrifugal force? Your blood comes out of your ears. Jesus Christ.

I had Felix Bumgarner on StarTalk. Yes, he'd check our archives. And he's a pretty good guy. I thought he'd be a little weird or crazy. What was he exploring? He liked exploring the limits of his own body's tolerances. Okay, so it's like a rock climber. How many rock climbers live to 40?

Nobody. You know why? They're after that thrill. After a while, you climb a rock, I gotta go further, I gotta go do more. And here's where I want to take this. Listen to me. Some of us do that.

And some of them die. Those who don't die figured out how to do it without dying. They'll write about it. There'll be someone documenting it. No. And it opens up horizons for the rest of us who aren't that brave. Wait a minute. And that's how we got out of the cave. You don't understand. Because whisk is our business. I've heard that.

They're adrenaline junkies. They need the adrenaline. And the adrenaline doesn't flow after three times. Dude, if we didn't have them in our species, we'd still be in the cave. Exactly. They're the explorers. Yes. And as they're falling, they say, I'm dying! And that's it.

But the next person that does it makes sure that they don't make whatever mistake that the previous person made their own mistake. And that's what these guys are. That's who the original group of astronauts were. I agree with you on the one-way mission is not something I would be interested in. Having lived in a...

in an enclosed, sealed environment for a year when you cannot walk outside. You know, Earth has like everything practically for humans. It has everything to offer. - Wait, Scott, Scott, we went 150 years with people coming from Europe on one-way trips to the new world. - Oh, I know it's for some people. It's not for me. - Oh, not for you? - I would not wanna live on Mars for the rest of my life. However, I would watch that reality show.

Because I think at some point it's going to turn into like Lord of the Flies situation. Oh, the darker side of what it is to be human. We're on to an interesting part of this thesis of what is exploration. Those who do explore, those not...

You know the the the the the Ranger with the deer and the penguin who asked a question That's one kind of exploration but the jeopardy of Exploration is something to be discussed who goes on what could be a one-way trip these guys didn't know they were they they they had to know when that guy when that brave

astronaut was seeing flames coming up from the entry point and screaming, I'm going to die. That's just his humanity. But he was willing to go. Somebody must have said, you know, son, the the tiles are going to heat up and you'll probably feel some heat and it's going to look, oh, it's OK. I can take that. But when you see it flaming and you're it's going to burn your parachute.

and you're screaming, you're succumbing to humanity. So you don't always know

Where your limits are exactly even if you have bravado leading up to that exactly your bravado and but but that's what that's what this general adrenaline is One more rock I can climb up up my fingers in there. I got a grip. I got a grip Do I let go with the legs? I don't know whether I can because I can tell you the only people friends I've ever had who died prematurely were rock climbers dying in just such an accident. That's why they do it

Free climbing. See, I grew up in a city. The city was dangerous enough. I don't need to add other dangers to that. I already was feeling it wasn't the exploration gene. It was a survival gene enough so that I don't need to do something else to put my life at risk. So what is your collective opinion on people who

are looking at, like the people who are going to go to Mars, once the instruments go, people are going to go for at least a year and a half. Wait, wait. So, Bill, I think the people who want to go to Mars have already noticed that NASA has plunked an SUV-sized rover on Mars following a half dozen other rovers that got there before it. And this current rover brought a helicopter. So, Mars is not some unbreached place.

- By humanity. - By humanity. So I think that they're not thinking they're gonna die. - No, but they know that the risk, like Scott was saying,

1% you know out of 99 99 1% that's pretty good odds I'm not gonna die but would you put the odds at 50/50 to go to to go to Mars I would say 50 things are very generous I agree for the first ones to Mars I agree and I think that's what they were considering maybe even for Apollo 11 right Charlie maybe a 50% chance of success really so now you're looking at guys

in the magnificence, and they were all men at that time, in the magnificence of their manhood. They were running on the beach. They were in the best physical shape. They've learned everything. Nine, six years of geology, Jose was saying, wasted on him because he was... Jose, another astronaut on board here. They're trained to the...

warrior degree. They are wielding their swords of intellect like the ancient Spartans. They're going to die nobly

1% chance that's what these guys were this the original 1619 What was it original seven original seven with the Mercury seven the original? In the spirit of your exchange letters of whom I die It it within a few years ago. I forgot exactly when it went public the letter that Nixon was gonna read

had Apollo 11 not successfully left the moon.

And if it couldn't launch, they'd still be alive until they died. And so you'd be watching them die. Which is another aspect. You couldn't test that LEMS takeoff, right? The LEMS takeoff could not have been tested on Earth. Well, I'm sure they fired the engine many times in a vacuum. Yeah, but I mean, one-sixth the gravity and suffering that journey and landing. But we do have the laws of physics, which work very well for us. Yeah, it's not just a random...

When we ignite it, where will it go? I don't know. Not where will it go, but will it work was random. Will it work in those kind of, with that kind of G's? Why? Every mission before Apollo 11 was incrementally leading up to that landing. Right up to Apollo 10, right up to Apollo 10.

We all forgot Apollo 10, but that one was important. It got to the moon, deployed. But if you're in an airplane in the density of this air, and you can pull a switch and eject, it's far different from circling the moon and wondering with this little collapsible thing

Rugal, what was it? The little hut that they were going to live in the moon, live on the moon, and get into fire to get back into orbit, and then climb from that back into there, and then get from there back to there. I mean, the chances were incredible. That's why they're heroes. That's why they're heroes. That's why they're heroes. Exactly. Exactly.

So we're running short on time here. One feature of Star Trek in the original series, and it trickled into other incarnations of it, was that there was a morality tale. So each episode was a lesson in how we treat one another here on Earth. But...

under the guise of, "Oh, it's just science fiction and it's aliens and it's..." So that would get you to comment on a lot of prevailing geopolitics, social cultural issues, racial issues.

My favorite episode was the one where guy was black and white and the other guy was white and black. With Frank Gorshin. In that episode, the aliens were exactly half black, half white. And one group of them were persecuting the other group. Why? Because they were black on the other half.

of their bodies. And so again, it's just the space, but really they're mirrors back to civilization, especially there in the 1960s, civil rights movement was still in full swing. So I just want to say to be able to explore and still

do something socially conscious, I think was with Gene Roddenberry as the creative genius behind it all. Yes, you should get a lot of credit, but there were other guys that really worked on this. You know, people as a... And I was a huge Star Trek fan as a kid.

My early memories were watching, sneaking behind the couch, watching Star Trek episodes when I was like five years old, when my mother didn't know my brother and I were there. What were you doing behind the couch? We were just hiding so she wouldn't see us. We were supposed to be in bed and we would watch. And same with me. We weren't allowed to watch TV during the week.

And it was scary. - So I had to catch most of it in reruns. - And Apollo 11 memories. But as an astronaut, people would sometimes ask me a simple question. You know the yes/no questions or the binary question. Star Trek or Star Wars? - What was your answer Scott? - I used to say when I was a young fighter pilot, oh absolutely Star Wars.

X-Wing fighter. Jesus, God, Scott, that's really loud. Scott, Scott, security, could you get him off of this stage? As I got older... Wait a minute, you're a test pilot, so you've got to be in your 20s. You know, once I got into my 40s, my 50s, you know, the harsh edges have gotten rubbed off on me a little bit. Clearly Star Trek now, because of the very reason you mentioned and how that show was just so far ahead of its time, decades ahead of its time. It cared about the laws of physics.

Unlike Star Wars, just to be clear. Just to be, I don't want this to go unrecognized. You flew for the Navy, correct? - Correct. - I just wanna make sure that's on the table here. - Why? - Why? - Why is it important that he flew for the Navy? - Oh, as a fighter pilot, oh, versus the Air Force? 'Cause the Navy, being a Navy pilot? - He's the perfect size.

Much more challenging than being an Air Force pilot. That's why it's important. Landing on the carrier. Landing on the carrier. Landing on the carrier at night apparently is the... That's the worst. Because I once went on a centrifuge at a... In Brandeis University, we were doing a show there and they had a centrifuge and...

They didn't put it at its fastest or anything. And I got off and my lunch came out of me. So I realized I was... None unlike this ship right now. I realized I was the inadequate stuff rather than the right stuff. But I can handle that because I have other talents I think I can bring. This is the second time I've talked to you in the last couple of days where your up-chucking has been a subject of my...

Is it a fetish with you? I mean, are you trying to release something from inside you? What is it? I'm exposing my vulnerable side to the audience. That's all. You're letting us see your insides. So we can land this plane here, if I may use a metaphor, or land this starship. When I look at the challenges of Shackleton and other polar explorers,

It is many dimensional. It is the temperature. It is the time. It is a place they've never been before. Well, do they have enough food? There's all manner of things that have never been breached before. And it's all rolled up into one expedition. And that's got to be the scariest thing ever. So can you just comment on that? Reflect?

It's one thing to say, Mars is at risk because there's radiation, or maybe I'll get a radiation suit or something. That's one thing. But if you've got 20 things that could kill you, you know what it reminds me of? I don't remember which film,

It's one of these sci-fi films where their hand, oh, I remember, excuse me, I remember what it was. It was a movie Contact based on the Carl Sagan novel where Jodie Foster's character is going to visit the aliens, all right? Because they sent us a recipe of how to do that. Before she gets on board this newfangled alien spacecraft, they hand her this thing to bite on that alien.

where she can kill herself, commit suicide. Cyanide, too. Some kind of, it might have been cyanide, I don't remember what it was, but it's, and she says, you think I'm gonna travel all the way just to kill myself? And they leveled with her. They said, we can list 100 reasons why,

Why you might want to do this? What scares us are the hundred reasons we can't think of why you might want to do this I I want to ask one question about about that very Element of torture. Yes. Okay, you're dressed in a suit from head to toe. I mean it's airtight and

It's it's water is flowing through it to cool it the the 200 degrees on that thing and your armpit itches What do you do? Well, you can't do anything the worst though is something on your face or it's a face Yeah, you can scratch your cheek and you can't scratch your cheek. What do you do? I?

You deal with it. What do you mean deal with it? Dude did the right stuff. They're not gonna freak out because their face itches. No, I don't mind dying, but I gotta scratch this itch. Nice.

Not something we really ever talk about. But it's so practical. As I understand, there was a variant on the spacesuit where they had like a thing where you can maneuver it from the outside and can scratch. I read about this. Is that true? I don't know. I've never heard about it. I just heard about it. You may have heard about it. I tested this. He was in one, okay? Whose word are you going to take? So I've tested this.

So I tested I said to myself if I'm in a spacesuit and my face itches I can't scratch it So I said how long can I go without scratching a face itch and I would stand there and initially it's a little twitchy. Yeah, but After a while the itch goes away so I pictured myself as an FBI agent and I'm hiding in a closet and the bed is in the room and I itch and

Gotta scratch this thing and he's gonna hear me scratch. You wouldn't be a good FBI. No, you have to deal with that itch Yeah, they'd shoot through the closet and then you'd be removed from the jeep. Here you got an inch. Where is it? I found you can resist itches if you wait long enough the itch goes away Is that right? I have found I did the experiment at least on myself, right? So now we've covered that all all of my shows when they have

Fun folks on. I want to give you a chance to ask me a question about astrophysics. Only because there aren't many astrophysicists in the world that

In fact, if you do the numbers is one in a million people in the world is an astrophysicist. So if you're ever in the same space as one of them, you better ask your question. My ambition is to sit down and talk with you about astro. All the stuff I have no comprehension about that you do. There's so much to learn. Ask me one question now. I can't think of one. No, no. Scott. Scott, go. I wanted to clear something up for you, Neal.

Uh-oh. Clear something up. From Twitter. October 9th in 2022, after the Top Gun movie came out, you said, late to the party here, but in this year's Top Gun movie...

Holy mackerel. Just sayin'. And then I responded to it...

And I said... Thus began the Twitter dust-up. Yeah, so I said, depends on his altitude. I was going Mach 25 when I left the ISS on a spacewalk, and that was just fine. Oh, that's true. Which is a lot faster. So...

And it was interesting to see this whole thing unfold because people chose sides. They so did. There was like, Tyson, you've never been in space, so I'm siding with the guy who's been in space. And other people said, you can't duck the laws of physics. So it divided right down the middle, I think. Yeah, and they thought it was just like beef, like we hated each other. Yeah.

It's Twitter. Let me ask you a question. Because the internet thrives on just that kind of... Let me ask you an astrophysicist question. You want to leave this dangling here? Okay, that's fine. I'll come back to it. He's going 18,000 miles an hour with no air and not suffering because there's no air. Because there's no air! Right. You're talking about

A winged airplane using air as a lift and ejecting at 10,000, whatever it is. Mach 10 would be 7,000 miles an hour. But there's almost no air where a Mach 10 airplane would fly. They would fly very high. You can't do that at low altitude. But...

That's kind of the whole point. Where there's less air, you can go faster so that you're still intersecting the requisite air molecules to measure the fact that you're going Mach 10. Next time you're driving down the street, 60 miles an hour, roll down the window. Or, oh sorry, how do you open windows? Lower the window. Lower the window with the button. Stick your hand out just like that.

You can barely hold your hand straight against 60 mile an hour air. That is a hard thing to accomplish. Now increase the speed of that air by a factor of 100. You'd stick your hand out there, your hand will just blow away. Separate it from your arm. And you're going to... We've missed 100 mile an hour winds here, but they happen all the time. Yes.

Now, pick up. Where are you going with your question? Okay. The universe is expanding. All measurements tell us that. Okay. So the star system that we saw, we think is the original one, is the farthest away, 13.8 billion years away. Where has it gone? Where is it going? That star system, we see it not as it is now.

Today, but as it once was 13.8 billion years ago because that light is only now just reaching Jesus you yesterday you said that it's instantaneous I mean you gotta have the rules follow the rules here. So wait a minute. So that still is my question There's only more compounded. So I'm looking at light from that galaxy 13.8 billion years away and it's

Another third is 26. It's 29.6 light years away now. Billion. So what's going on is there's the light you see from objects formed at the beginning of the universe only now just reaching us.

Today, that object is way farther away from us than that. So the universe is far larger. You just can't see that. Yes. The measurements of the universe is far larger. It's like 90, nearly 100 billion light years across. So it's like immeasurably big. So what is space? Gotcha.

It's the final frontier. Oh! Mic drop on that.

Let me say Scott it was fun doing a little dust-up with you on Twitter just to see how people chose sides right They thought we were just enemies and they wanted to watch it happen, but it was fun. It was a it was a highly Educational moment for people they'd see what what's going on there. All right, Bill. Yes, you're my man You are my man. You are you are treasure not only to me but to everyone assembled here on this ship and

To the country and to the world your enthusiasm your boyish curiosity Child childlike curiosity is infectious. It is contagious. It's I don't want to use these biologically bad words it is

It's, yeah, it's contagious. Great. It's contagious to us all. That's what we can tell you. And this past year, you had your 93rd birthday. My birthday is March 22nd, so it's not that far away. You're going to be 94. I'll be 94. And we have, there's a documentary about,

Called you can call me bill that's out and around the round making its rounds right now It's really good and I was with you for the New York premiere of that which I delighted in just to And just if I can steal another minute here, could you tell us all? Recount for us all as you did in the film What were you thinking after they had cancelled Star Trek after its third season? We haven't yet landed on the moon

And you're living out of a trailer trying to... Did I tell that story in the film? Or maybe you told me. But you're in a trailer in regional theater trying to make a buck. I have three children. They're going to school. I was getting divorced as the show was being canceled. I was broke. I couldn't write a $15 check at the end of Star Trek. I acquired, I think I bought an old truck.

with a cab on the back and a dog, a Doberman. And I put together a summer theater show. And I drove across the country to the Cape, Boston. Cape Cod. And did summer theater for 13 weeks.

Turned around, headed back home to go back to my family. Made a point of calling my agent every day from a gas station, put the quarters in with him, and he said, "Oh, Rose Kennedy wants you to come to a party. Can you come to?" I said, "Well, I'm on the road. I can't come to a party. I gotta go see my kid." "All right, well, call me tomorrow." I called him tomorrow.

He says, "I'm telling you, Rose Kennedy wants you to come to the Kennedy party and the thing over there. I can't come. I get to Phoenix. I call them." He says, "They'll send an airplane for you."

had i not been so blinded by coming home in this pilots know about the danger of coming of home is it where you you sacrifice the rules to get home you're so anxious i sacrificed the rules i could have asked her send the plane to arizona fly me to los angeles pick up my kids fly back to new york

Meet the Kennedys and fly me back. I didn't think of it. And that was my journey, my initiation after Star Trek.

So it went to a low and then it has been ascending ever since. I've had good luck ever since. And of course you have the book To Boldly Go. What's that? Boldly Go. But there's more than one book out there. Okay. Yeah. All right. We'll look for those. And Scott, what projects you have going right now? I do a bunch of public speaking. I'm on some, you know, advisory boards. Yeah. Okay. You know, I write a little. I have some other book ideas I need to start working on. He's a wonderful public speaker. Yeah. He's perfect in front of an audience. Yeah.

Guys, thanks for coming back onto StarTalk. Yeah, it's great. So this has been StarTalk Live in a voyage sponsored by the Future of Space, an organization that's trying to connect us to exploration. Absolutely. And this is the inaugural voyage of the Space 2C trip to Antarctica, which brought the three of us together. Fortuitously. Fortuitously. Yes. I'm Neil deGrasse Tyson. You're a personal astrophysicist. And as always, I bid you to keep looking up.
