Yuri's Night, 26. This week on Planetary Radio. I'm Sarah al-Ahmad of the Planetary Society, with more of the human adventure across our solar system and beyond. On April 12, 1961, Yuri Gagarin became the first human to reach space. 65 years later, we celebrated that milestone at Griffith Observatory in Los Angeles. Throughout this episode, you'll hear from educators, engineers, and space explorers, all of whom, share some common ideas. We talk about what we can do in space to inspire that next generation, and how seeing the Earth from space changes our perspectives about humanity and our future. First, we'll hear from Laura Tomlin, who's the CEO of Space for Teachers. She talks about

inspiring the next generation through hands-on microgravity research projects that put real science in the hands of students and teachers. Then robotics engineer Kalynne Carpenter from NASA's Jet Propulsion laboratory walks us through some amazing tools and robots he's helping to build that are going to be exploring the moon and beyond. Software engineer David Hernandez from Blue Origin was working at the Club for the Future Booth, an organization dedicated to getting the next generation excited about space. Research scientist Robert Green, also from JPL, talked about the invention of imaging spectroscopy and what that can teach us about the worlds around us. Later I caught a up with aerospace engineer Andy Sedwani, who flew to space aboard Virgin Galactic.

He shared what it felt like to see the Earth from above and reflected on what the Artemis two astronauts must have experienced. Then we'll transition to the main stage at Yuri's night. First we'll hear from cinematographer and polar explorer Janika Mickelson. She's Norway's first astronaut. She'll tell us why we need storytellers in space just as much as scientists and tell the story of her historic polar orbit mission. Space philosopher Frank White, who's the author of The Overview Effect, is joined by actress Nadine Nicole from The Expanse and commercial space explorer Christopher Huey for a panel discussion on what it means to see Earth from space and how that perspective can change everything. And finally, NASA astronaut Ron Garron brings it all together,

sharing his own journey to space and reflecting on what we can learn when we take a step back and see our planet as a whole. Of course, we'll close out with our chief scientist Bruce Betts in this week's What's Up. He shares the lesser-known story of what went wrong the day that Yuri Gagarin took his first historic spaceflight.

By subscribing, you'll never miss an episode filled with new and awe-inspiring ways to know the cosmos and our place within it. Yuri's Night is a global celebration of human spaceflight, held every year on or around April 12th.

It marks the anniversary of Soviet cosmonaut Yuri Gagarin's historic first flight, the first moment that humanity crossed that boundary into space. Yuri's Night was founded in 2001 by Loretta Hidalgo Whitesides and George Whitesides, who saw an opportunity to unite space enthusiasts around the world in a shared moment of celebration and inspiration. In the 25 years since, it's grown into one of the largest space events on the planet, with gatherings around the globe. And this year's celebration was a special one. It marked the 65th anniversary of Gagarin's flight,

the 45th anniversary of the Space Shuttle Program, and the 25th anniversary of Yuri's Night itself. And by strange and beautiful coincidence, it also happened to be one day after the Artemis II mission splashed down, marking the first return of humans from lunar space in over half a century. The Los Angeles Uri's Night Celebration has traditionally been held in other locations, but this year it found a particularly fitting home at the iconic Griffith Observatory. The observatory is perched above the city of stars with the Hollywood sign visible in the distance.

I want to give a special thank you to the Griffith Observatory Foundation, who not only helped make this night possible, but granted us access to the audio of this event. Griffith Observatory Foundation is the nonprofit that supports Griffith Observatory. Their mission is to keep this Los Angeles landmark open and accessible to everyone for free, supporting science literacy, public astronomy, and free education programs like their fifth grade school program. You can learn more about their work at OBS.la.la slash support. And it was quite an event to put on. The crowd that gathered that evening was a mix of space enthusiasts and families and some really special guests.

The event also had ambassadors stationed throughout the grounds to talk to attendees about space exploration. It was my first time serving in that role, and I had so much fun talking to people about space for literally hours on end. Out on the front lawn, under the open sky, organizations set up booths to share their work with the public. Here are some of the conversations I had with some of the exhibitors. Hi, I'm Laura Tomlin. I'm the CEO of Space for Teachers. We are a nonprofit focused on microgravity research opportunities for teachers in their classrooms. That's amazing. As the daughter of a teacher, I know how important it is for teachers to get the resources to share this kind of thing with people out there. What are you been doing here

today to try to encourage young people to get more interested in space? So today we are spreading the word that our teachers are heroes. They are working really hard every single day. They make their students like rise to these challenges, right? Students are so capable of doing really hard things. And I think a lot of times they don't really get credit for that. So when you bring these difficult challenges to teachers and to students both, it's amazing what they can do in the classroom. So as our organization, we work directly with teachers to develop microgravity research projects. Basically, we help guide the teachers and then the teachers guide their students on these microgravity research projects. We work with them weekly. We take them through the technical

design review of their research. We take them through payload integration, through flight safety reviews, and ultimately the teacher will then fly their student design on a parabolic and test it in microgravity. So it's really powerful that these students can see the things that they built in space with their teacher being tested and getting that data back. It is just the coolest, coolest thing. And these are projects that are aligned with academic research, industry research. They work with SMEs, so it might be on like a propulsion management device looking at separating out bubbles from liquids in a fuel tank and designing devices that can do that to slosh spaffles to how to flush out wounds and microgravity. There's all sorts of experiments they do that are aligned. And, you know, a lot of people think that, you know, a sixth grader can't do this or an eighth grader or a twelfth grader, but they can.

It's all based on fundamental science principles. And when you pose it to these students that they are answering these real questions, That is inspirational. It teaches them that they can do really hard things. And that's the beauty of space exploration is space brings everybody together under, you know, just pure inspiration, pure exploration. And it makes people strive to do the near impossible. Being able to work on that kind of actual science as a young person, I think, would have meant the world to me. And I'm sure you've heard from a lot of young people who've been very inspired by this,

would have been some of your experiences talking with both the teachers and the students? It is profound. From a teacher's standpoint, you're really getting your, it's uncomfortable, right, to work in this situation. And it's not just me, this is we work with teachers, you know, all the times. And it's the same across the board. It's uncomfortable to step out of that zone of, you know, you feel like you know everything in the class. You've been teaching it for 15 years over and over again. And all of a sudden, you were the student again, and you were having to learn these things and learn them right there alongside your students. So it's this process of serious challenges, some intimidation followed by wins, followed by challenges. And it's this roller coaster throughout the whole process that just culminates in this remarkable moment of the realization of, hey, these are what my students feel out here in the classroom.

I understand that now. And it's just a really big learning process for both. It was for me. It is for the teachers that I work with. Before I was a teacher, I was a biologist. I was a plant pathologist. not a, you know, super well-known field. When I started teaching in the classroom, I would always bring in, you know, some plant

disease aspects, a little plant pathology. And so on one of our parabolic flight, basically it was looking at disease resistance. Does a plant that has flown in microgravity have a different susceptibility to disease? And so these were six-and-seventh graders at the time, and we went through this whole process of growing plants, flying them on a parabolic flight, bringing them back, inoculating them with diseases. They had to learn all these different techniques. And at the end of the year, we always give a survey for the program that's, you know,

what fields or careers are you interested in? And we list all 30% of the students checked plant pathology. And I was like plant pathology has never seen these kind of numbers. Never. So, but it wasn't just that. It was engineering. It was biomedical research. It was all of these things.

When they started, it's maybe an astronaut, a lot of, you know, astronauts, engineers, that sort of thing. but they just didn't know. So this is an opportunity for these students to see, hey, look at all of these opportunities. There's something out there for everybody. How can people learn more about your organization and help support your work?

You can go to spaceforteachers.org. So we are called space for teachers because really what we try to do, our mission is to make space for teachers in real research so that they can bring this to their students and have something that is meaningful and authentic research in the classroom. There's no better way to learn. So spaceforteachers.org.

Thank you so much. Thank you. My name's Kalyn Carpenter. I tell many of the children that I give talks to, I'm a robotics footwear designer. What does that mean exactly? Well, robots need to get from point A to point B, and depending on where they are, there's different fundamental physics available to them.

So I've worked on Mars helicopters that can fly. I've worked on a lot of different drone ideas like shape shifter for Titan. I'm the inventor of the exobiology extent life surveyor Eels robot to get through the fluidized media of Enceladus, try to get down through the vents and swim in an alien ocean. One of the people that came up with the idea for moonfall, so we were ending the sample recovery helicopter and we're like, well, we've done great work. What could we do on the moon? We're like, well, we can't use blades, but could we use some type of thruster. So we started looking at what we could do to basically take this team, take this great

work we've done, transfer it to the moon. So thruster variants, we're looking at ones where you can actually harvest water ice from any of these bodies, have an airless body drone that would be a multi-body solution. So working a bunch of component technologies to start moving into that. So we don't have to reinvent these things. But yeah, each of these, this has moved into manipulation. I did the spring wheels that are on our endurance, a rover test bed that we want to send to the moon to do 2,000 kilometer

drive, get 100 kilograms of rocks to be able to age date the moon also understand its whole entire geologic history. And then I do sensorized grippers, underwater grippers, sampling systems. Each one of these basically

touches the world. It's how the robots touch, interact with the world, and do the function that they're designed for. You have a really cool job. Before I say anything else, can I say I love the Eels robot? That's such a cool concept. Thank you. Thank you.

It's personal favorite. So you previously worked on sample return concept, kind of like ingenuity, but to pick up some of these samples. Are you excited about these new Ignition Day announcements now that the plans for what we're going to be using these helicopters for has changed a little bit? I'm extremely excited about it. I've actually spent last weeks going through. the whole entire output from that, analyzing where are there shortfalls, what technologies do we need, what's going to make this so that we can stay on schedule, on budget, and really achieve it. We've broken everything down by timeline, by mass, what might be missing, what things are being

overlooked. And there's a request for information out right now that we're being responsive to to make sure that we're going to be able to meet these goals for humanity. Well, congratulations, and good luck with that. is a big next step, but after seeing the way that ingenuity absolutely crushed it, I cannot wait to see what multiple ingenuities can do. Thank you very much. We're very excited. I am David Hernandez. I am a suffer engineer at Blue Origin. So you're here today at this club for the future booth.

I want to say a few years ago, I made a postcard to send a space, and I waited a long time, and it finally arrived back at my home. It's been so cool finally getting that. Can you talk a little bit about what you're going to be? program does and what kind of outreach things you do for the young people? Yeah, I mean, Club for the Future is really all about getting the next generation of folks excited about space, right? It's becoming an even bigger and bigger thing. I mean, Artemis just happened, right, like literally yesterday as they're talking. Yeah, and you can see, you know, currently kids are out here doing their little postcards and we'll get their back the same way that you did. So we do

things like this. There are other events that are also hosted, like we go to different schools, to talk about what is it that we're doing, and have the kids ask questions to us, you know, about what they're interested in space and any sort of engineering thing related. So it was the Artemis 1 launch. I missed the actual launch, but the day after I got to go to a Blue Origin factory

for the first time, I got to see the bits of new Glenn laid out. It wasn't all the way together yet. What is it like working at a place where you guys are on the verge of you just finished directing this giant, giant rocket? It is fantastic. I love going down in Florida because I feel like a kid at a candy shop walking through there. I'd imagine you might have felt the same way, like seeing all the hardware out there, seeing how massive that rocket is.

It's fantastic. And then seeing it, unfortunately, I wasn't there when our first new Glenn launched, but I saw it go up, like, be good lifted, right? So yeah, it's absolutely amazing. Yeah. What parts of the rocket have you worked on personally? So I am a software engineer working on our enterprise system. So I build the tools to help the engineers build the things. So focusing a lot on AI, specifically on ensuring that AI doesn't hallucinate answers. You know, hoping to get the engineers that are actually working on something, right, if they need some sort of data, they have any sort of question,

it's able to quickly give them that response and really help them, you know, 10x, 100X, X, the work that they're doing. How do you prevent them from hallucinating? Are you creating just a specific kind of database for that LLM or there are other ways? that you're restricting the software. Without getting too into the details. So one of the approaches that we're taking is what's called Rags, so retrieval augmented generation,

wherein we give the LLM the actual data that it's going to be using and then put some guardrails around it to ensure that it uses the data and not whatever hallucination that might come from the LLM itself. That's a lot of fun. And honestly, that's like a juxtaposition of so many modern-day technologies all at once. What has it been like seeing people finally begin to use AI in the space realm?

Oh, it's been amazing. Like, how cool is it to say that we're using AI and space-related technologies? Right? It's as futuristic as you can get. And I've really seen how, yeah, it's helped quite a bit. I was even as a software engineer, I was a bit of a skeptic. And I was like, I don't know how good it's going to do. And then the new model started coming out.

I was like, wow, it's amazing. You can do quite a bit with it. You can automate quite a bit of tasks. Yeah, it's been fantastic. Yeah, well, we're not trying. trying to create a full, you know, like AGI or whatever at this point. We're just trying to make sure that we can augment the ways that we go to space and help automate these things so that our spacecraft can do things on their own and that our astronauts

have better ways to access data. So I think this is a really cool usage of that technology. Yeah, it's fantastic. Really, that's what it's for, right? We want to make sure that we are helping and enabling the engineers, helping and enabling the entire chain that's building this rocket, right? Because it is such a complicated system that any help that we can give, It gets us to get that launch cadence and start going up pretty quickly and coming back down and reusing the rocket.

So, yeah, it's been fantastic. So I'm Robert Green. I'm a research scientist at the Jet Propulsion Laboratory. And you work primarily in spectroscopy, right? What kinds of missions are you putting your work on? So I came to JPL to work on something called imaging spectroscopy, which was invented at JPL quite some time ago as a way to go to planets in the solar system and understand what molecules were on their surfaces,

whether it's Mars, the moon, or Europa, and it also has relevance at the Earth. So we built a class of instruments called imaging spectrometers. The first generation went to the outer planets to Saturn and Jupiter. The next generation is going out now. There's MIS on Europa Clipper,

heading to Europa. And Mid is on the space station looking at our planet. We're building Eustis Moon to go back to the moon, and we have a plan for Mars as well. All these instruments, give us spectra for every pointed image. So we know what molecules are present, and we can pose or answer questions,

whether there's scientific, whether it's in-titu resource utilization that you'd like to know at the moon. I was involved with the Moon Malibrapper, which, of course, in 2008 and 9, produced those first spectacular maps showing that there was water and hydroxyl on the illuminated surface,

and subsequently evidence for ice at the poles of the moon, and that's driving some of the thrust, as we move back for those resources, focusing on the polls. And just recently at the National Academy, their Science Division announced the Eagle Vesware Mission, which will look at our planet with 1.5 million spectre per second, and it's also pathfinding for the next generation to go to the moon and Mars.

All these spectrometers are helping us answer new questions, both applied here on Earth, critical minerals, agriculture, fire fuels, really relevant in California. we would know where the fire fuels are and how we might mitigate. So that's my passion, and that's what I've been involved with at JPL. How does it feel, having worked on the Moon Minerology Mapper, knowing that in part the future angle of where the Artemis astronauts may land on the moon is in part due to the data that you and your team collected?

Well, it's just extraordinarily wonderful. We built an instrument knowing we were just trying to see if there was water maybe at the edges of some of the permanently shadowed craters. And when we got there, we saw that there was hydrology, hydroxyl absorption way down near the, all the way down to the equator, and of course, quite a bit at the polls. So we made the case with the evidence, backed it up, and now that's a pathfinder that's giving us focus to go after those resources. So it's wonderful. It's, for me, it's the gift of sticking with good spectroscopy. We're all looking forward to

Europa Kippa actually getting to the Jovian system, but it's not actually going to be getting beneath the ice. Clearly, there's this giant ice shell. But what can we learn from the spectroscopy of the surface of this world that might give us some clues to its habitability. Well, we're going to see the chemistry of what's on its surface, and there's lots of evidence that materials from the subsurface have made it to the surface in various places. So we're going to be able to interrogate those and look for the various lines of evidence to give us more information about the nature of that ocean below the ice shell. So it's extraordinary, and we're so excited. It's an important first step, and it's wonderful to be involved with that. Diana Blaney, of course,

is the PI of the Mize imaging spectrometer and a close colleague and friend. Well, I always love it when people come to these kinds of events with cool props in their pocket, but I'd have never met someone who had a spectrometer in their pocket. This is amazing. How does this work? We're going to show you spectra of the sun and the Earth's atmosphere. Let me just get it going. It's wild that we now have this technology kind of shrunk down to the size where you can just literally keep it in your pocket. It's maybe on future Mars science helicopters.

In fact, we have a version there. We'd love to do that. Hopefully we get to do that with, let me. So I wish everyone could see that, but that's a spectrum of the sun. And here you're seeing, I've got to hold it, endpoint. I need a third hand. But anyway, that's oxygen in the earth's atmosphere. This is water vapor.

These are solar Fraunhofer lines, and we're seeing that all real time. If I point it down, we see the chlorophyll of plants. So all the molecules in the solar atmospheric system are revealed right now with a spectrometer I procket, linked to my cell phone, which is where this display, and this is, this is extraordinary. My vision is this will be one of the tools. You have cell phone cameras, which actually the CMOS camera was invented at JPL long ago by Eric Fossum. Hopefully we'll be jumping to full spectrometers in people's cell phones as I'm starting to take that path here with this one. This is such a cool technology, and I cannot wait to have one for myself. I think anybody who's

deep into space technology understands the power of spectroscopy, what it's taught us about our own world and the world's beyond. And honestly, it is one of the most powerful tools we have for understanding the worlds that are not in our solar system. Absolutely. For exoplanets, that's what we're going to be using. We're going to use the chronographs to get the light from the exoplanet. We're going to feed that into spectrometers. We're going to see what molecules are there and what hypotheses they inform. Hopefully, maybe a case for evidence of planets like ours. Well, we'll see. We've seen some hints here and there, but the fact that we can even get that kind of data about these worlds at all is just so amazing. What a time to be alive.

Yeah, when I was born, there were nine planets, then there were eight. Now there's thousands. How extraordinary is that? Later that evening, I stepped inside the green room where the other ambassadors for the event were gathered. That's where I had the chance to meet Andy Sedwani. Hi, my name is Andy Sedwani. I'm an aerospace engineer, and I had the opportunity to fly. Virgin Galactic in 2024. What was that like to actually see the Earth out the window? It was absolutely incredible. The first words I had when I looked at the window were, oh my God, it's just an amazing, amazing planet.

It looked like this giant blue ball floating in this fast sea of darkness, and it was moving, you know, quickly around the Earth, and we were just amazed to see this beautiful view. I feel like there are some things that you can try to understand on paper, right? You can think in your head, like, I know what it might be like to go up on a rocket. But how different was the actual experience and how did it change your opinions of the experience for others? I've seen so many pictures of the Earth. And I've also performed data review on actual launches and seen the Earth and video. Nothing prepared me for what I saw at the window.

It was an electrifying blue. And the atmosphere looked alive. And it was just this shield that would protect us and protect all the, living organisms on the planet. I don't really have the words to describe it. I guess what I could say is I discovered some new colors when I looked out the window. What advice would you give to people who hope to go to space and sell someday? Any altitude is attainable with the right attitude, and chance favors a prepared mind. Like, whether you think you can or you can't, you're right. Getting yourself in order and working towards the things that you would need to, you think you would

need to do to become a space explorer, you can start now. So, you know, whether that be studying about other people's space travels, reading biographies, taking flight lessons, doing scuba diving, or just, you know, touring NASA space centers. After having been through this experience, what do you think those Artemis II astronauts were feeling when they splashed down yesterday? Watching them splash down live was phenomenal. Part of me was thinking about what is the vehicle feeling. And then the other part was, what are they feeling? Like, what's the splashdown feel like? What are the emotions that they have upon reaching Earth? What are they thinking about? Are they thinking about their family, their mission? Are they thinking about what burger they're going to order?

You know, like, what would they get back to the mainland? Well, thank you so much. And honestly, it is so wonderful to meet people who have that space perspective and to be here at Yuri's night together. So thanks for sharing that experience with everyone who came here to celebrate the first space traveler together. Absolutely. My pleasure. Sarah. Thank you. We'll be right back with the rest of Uri's night, 2026, after this short break.

Greetings Bill Nye here, chief ambassador of the planetary society. Last year you showed up, and it made all the difference. Tens of thousands of you sent messages to Congress, you traveled to Washington, you made your voices heard, and together

we stopped nearly 50% in cuts to NASA science. That victory that was you. But the fight isn't over. New challenges are here. Your gift today keeps our advocacy efforts going strong so that next time we can act fast,

fight hard, and win again. Together, we're not just saving NASA science. We're protecting humanity's greatest adventure. So please check out planetary.org slash take action. And together we can carry on, keep exploring, and change the world. Thank you.

As the sunset over Los Angeles and the city lights came out, the celebration moved inside. Many of us gathered for an evening of stage presentations that focused on human experience in space. We heard the stories from people who had ventured beyond our planet and returned transformed by what they saw. I'm only going to be sharing brief segments of the two-hour presentation, but I'm going to add a link to the full video of all the talks so you can see all of the images and the beautiful video that people share. That's going to be on this episode's web page. The first speaker of the evening was Janika Mikkelson, who's Norway's first astronaut. She's also a cinematographer and polar explorer.

When she flew to space aboard the Fram II mission, she became part of the first crew ever to orbit over both the Earth's north and South Poles. My language is film. I am an astronaut, but I'm also a cinematographer. It's amazing. It really is amazing that we've come to a time where four first-time flyers can fly together on what is called a side quest because the dragon was never made for this kind of space exploration. I live in Svalbard. It is an island pretty close to North Pole, the most northern settlement.

And we are 2,500 people who live there in a town of 3,000 polar bears. And it's kind of like living on the moon, except. you know, we have oxygen, but we do also have polar bears. So I loved riding really fast on my horse. My horse was called Star, and then one day I fell off, and that meant I had five years of learning to walk again, and during the time I couldn't go to school. I actually studied space. My teacher was like, just studying anything you're interested in.

And right then was STS-99. And with such a boring name, it ended up being an awesome mission to follow. as an 11 and 10 11, 12, and 13 and 14 year old. I followed this mission for years. I actually called NASA and applied for a job. And my mom called NASA and told them, well, she's only 14, so she can't apply for that internship.

And then I refuse to talk to her. But that career, you know, I'm going to go back because the cool thing is I probably talked to a reception at the Johnson Space Center and she's like, well, you know, you're in a wheelchair. an astronaut probably isn't a realistic dream for you. But you can be the world's best in 3D. You could become a 3D technician and engineer.

I'm like, yeah, I'm going to be the world's best in 3D. And that's actually what recruited me to the front to private space mission, the first ever polar orbit of a spacecraft. And my job, actually, not only I'm at a vehicle commander, my job is to photograph and film that orbit in 3D and, you know, regular 2D. actually landed on the 4th of April last year, 2025. This is my one year celebration. Yeah.

Our mission is called Fram. We are honoring the polar ship Fram that went to both North Pole and South Pole in 1911. Well, I love the most about this mission. 1911, they brought a cinematographer because they understood how people in Norway are we going to understand where we've been and what we've done if we do not document it and continue telling that story.

And then finally when we're in orbit, you know, we're safe. And I'm able to do what I love the most and as being a cinematographer. And what, you can plan a lot in 18 months. So we started planning 18 months before the mission. But once you're weightless and all your equipment's weightless, oh man. So you do learn to switch your orientation. Look up when you lose something. Don't always look down. But the thing I noticed, or the thing that puzzled me when I was in space, I've learned about a blue planet at school, but when I looked out of the window, I didn't see a blue planet. The planet I saw was 50% of the time like this, because we're 25% Arctic, 25% Antarctic. And you don't really see countries. The easiest place to see is the Nile, and then you're like,

ah, Egypt, got that one. That one's easy. But it's actually really difficult to see countries when you're in space. I belong to the new generation of astronauts. We are private. There's only 11 of us and we have diverse backgrounds like myself being the first ever cinematographer. Lucky enough to receive an astronaut training and that's why I try to talk about. You know, when we're going back to the moon and we're going to stay and we're going to build a moon base and we've got the Artemis Akkort. That means that we're going to have all nations joining in that moon base and we are going to have people going to the moon to work and you're going to need all the different roles you need to operate the town on the moon. But after,

being in space, like all of you, I was watching the Artemis two live streams, and Commander Reis Weizman said something beautiful, and he says, you know, about Earth, it's a special thing to be a human, and it's a special thing to be on planet Earth. Because out there, you know what? There's nothing. You're out there, and you're looking down, you're like, all molecules are there. And it's a bizarre thing. So thank you for your time. And also, it's very important to inspire. I'm the first Norwegian astronaut.

There will be more. So I'm actually wanting 40 astronauts to come to Norway to inspire my nation to become the next astronauts going to the moon. Yanukkah story is just such a great reminder of why we need to send storytellers into space. The images and the video that she shared that night were absolutely spectacular. there's something really powerful about the ways that we can tell the story of space to people down on the ground through these formats, because that perspective can change a lot about the way that we see ourselves and our place in the universe. Immediately after that conversation, Frank White, who's a space philosopher and the author of the groundbreaking book, The Overview Effect, took to the stage. He was joined by actress Nadine Nicole from The Expans, and Commercial Space Explorer Christopher Huey,

who also goes by Chui. They talked about the Artemis II mission, and what happens when people see the Earth from space? Something happened in 1961. That was tremendously important in terms of space. Of course, that was Yuri Gagarin's flight. Something important happened in 2021 when we had the first commercial spaceflight,

so the spaceflight. What it means is everybody here, could actually fly without being a NASA astronaut. We are the new astronaut corps, every one of us, right? There was a contest called Inspiration 4. The current NASA administrator put that together, funded it, ran it. Loretta and I competed for one of those seats, along with two of our friends. I was all gung-ho, you know.

Then I realized there's not going to be any professional astronaut on board. And there are not that many people applying. I could win. Be careful what I wish for. Well, this is also a series of speakers where the astronauts outnumber the non-astronauts. You know, we're seeing a really big change. So, Chui and Nadine, I think we have to talk about Artemis. Yeah.

We just have to. Yeah. What did it mean to both of you that we returned to the moon? We really hadn't been there in so long. It was at a time of incredible strife, division on the planet. and there we saw a perfect mission. Pretty perfect. You've flown.

What did it feel like to somebody who's flown? Do you think it was different for you because you've been there to see Artemis or what was it like for you, Julie? You know, I think it's relatable, but it's also just so different. like being 50, 60 miles up is nothing compared to being 250,000 miles up. And the pictures that were coming back in the video were just incredible. And I think the overview effect is about putting things into perspective. And yes, when you go to low Earth orbit, you really are low in Earth's orbit. And you can see the Earth, and you get appreciation for where we are in context of, like,

she said, you know, there's no, you can't see the borders unless it's like a river, like the Nile. But like the further out you get, the less you start. to find ways to organize and divide. You just see cohesive, one unified planet. And so seeing those pictures coming back, especially from the dark side, not really the dark side, but the far side of the moon.

Pink Floyd, nay, it's ruined. The far side of the moon. Great album, by the way. The far side of the moon. It's just like, yeah, we really are alone. And I remember thinking about, when I was in space looking at the Earth, I was thinking about how we are all one

and how we are all together and that we're connected, you know, the overview effect. But what I saw in the pictures from the moon in Artemis II is we are alone. Like collectively, the Earth is by itself. Because like when you go to space, you have perspective. You can see where the Earth lives.

We live on the Earth, but the Earth lives in space in our solar system, in the darkness, and the blackness of nothing. And we got to see it like, yeah, the Earth has a home too, and this is it. Like, it's basically a cabin by itself, and there's nowhere else to go that can sustain our life. We have to bring life support with us wherever we go. So I think it is different, and I think it'll certainly inspire. The cool thing about Artemis is like, you know, it was a long time since we've flown to the moon,

and, you know, we almost dropped the ball. We almost lost the ability to do big, amazing things like this. because yes, we write down engineering plans and we make all these engineering drawings and send these missions, but there's so much tribal knowledge that's built in people's head that gets passed along. Building a big, complicated rocket is big and complicated. It needs really a large amount of smart people

and continuity of education and just to keep the passing on the torch. And so if you wait too long to do these things, you will have to relearn those lessons and there will probably be more failures that we don't need to have. So it's just so important to keep up the momentum. Very well said.

Nadine, you and I, I are the non-astronauts here. Yeah. Yeah, it's kind of weird, isn't it? What did it mean to you to watch Artemis? I love that the whole world had eyes on it. It was very similar to the movie Look Up, where we had this collective moment where we could all understand that we're at this pivotal moment in time.

We're not just the space explorers anymore. We're moving to enhance. space for the first time. Like, this is our time. It's such an incredible time to be alive. The juxtaposition of all this division that's happening on our planet and the desire for connection is an interesting time for this to happen, for us to have the perspective from them and their experience up there.

Because we send astronauts and we think they're going to have a technical experience, but they're up there, like, hugging and talking about. grieving and telling everyone here their message of unity of you know seeing the the separation dissolve and just seeing the oneness of everything and they're sending these messages back and I think that that gives us such a cool opportunity of this perspective that we're missing here on earth right we're living in the separation we're living in the illusions it's hard we need that perspective to evolve and just being in this time and space here and

now, I think it's just an incredible time. Even though it seems like a geopolitical move, it's not like, you know, there's a lot of tension between countries of like who is going to own the moon or who's going to own space and what that's going to look like. And I think that's the big question that we need to put out there is who is space for, who's going to have access to it, and what design systems are we going to embed into it? If you'd like to explore more of Frank White's thinking, we actually have a really wonderful book club edition episode that's dedicated to his book The Overview Effect.

You might want to look that one up because it's just absolutely fantastic hearing Frank's experience speaking with astronauts. But to close out the evening, we heard from NASA astronaut Ron Garan. He's a fighter pilot, a humanitarian, and someone who spent six months aboard the International Space Station. Ron had a really powerful perspective on what it means. means to see Earth from space. And what's possible when humanity works together?

Does anybody feel like we're at an inflection point in our society? Does anybody not feel like that? So yeah, we're at an inflection point. And what I've been hearing all night is about the power of perspective. And that's what leaving the planet really does for us. It gives us a perspective. So thank you for this honor to have a conversation with you, to recognize to recognize that moment where humanity was able to take the first steps towards the stars.

Like I said, outside on the steps, it's really poignant that we're having this celebration the day after the splashdown of Artemis II, when those folks came back from traveling around the moon. It is amazing that we're going back to the moon. That was a sign that this isn't just an idea, this is a reality. We really are going back to the moon. We are really going to stay. this time. And what the power of the space program is, is it gives us the opportunity to realize that when we set aside fear and agree to work together, we can accomplish anything, that nothing is impossible. And together, if we take that same mindset, that mindset of the space program, and we do bring it down to the Earth's surface, we can solve the problems that are in front of us. Seeing the

planet from space, I think you'd be amazed at the thinness of our planet's atmosphere. And in that moment, you'd be hit not only by the sobering realization that that paper thin layer keeps every living thing on our planet alive, but should also be kept by the sobering contradiction between the incredible beauty of our planet and the unfortunate realities of life on our planet for a significant number of its inhabitants. But I also think seeing the planet from space would fill you with hope. Seeing what we can accomplish when we were together, as evidenced by the International Space Station itself, would extend your optimism. Your definition of the word home would expand rapidly to encompass the entire planet. And for the first time, you might truly understand what it means

to be part of one human family. Now, obviously, you don't have to go to space to realize any of this, but traveling to space started me on a journey towards a deeper understanding of the underlying inherent beauty of our interconnectedness, of our unity. Going to space made a lot of things become clear. From space, it's clear that everything is changing, and things are changing faster, than ever. And it's not just happening in one region or industry or nation. It's happening all across the world and is affecting all sectors of society. As such, the mindsets, the

approaches that have led us here, that have led us to this moment in history, are rapidly become antiquated and ineffective. But this creates an opportunity for us and for those that can adapt. Now, in order to successfully capitalize on the opportunities that are all around us, we need to take a holistic approach and strive to see how everything fits together. We need to understand that moving towards a more inclusive, just, and stable world, while protecting the environment, protecting national security, and improving our economy and businesses are not mutually exclusive. They are all complementary.

In fact, they are more than complementary. They are required. We can take a socially just and environmentally sustainable approach to business that all increases profitability, and we can also protect national security for the long run by rising to a higher vantage point, expanding our perspective, and seeing the bigger interdependent picture. Above all else, we need to understand that as daunting and challenging is all these changes that we've seen, they're just the tip of the iceberg, we are entering into a new human epoch where everything will change, especially how we solve the problems facing our planet and

how we conduct business. And one of the best ways to navigate the uncertainty and the chaos that's all around us is through collaboration. Collaboration that leads to shared strength. Now, over the course of my career, I've had the opportunity to have some amazing experiences. And these experiences, I believe, have given me a very, very unique, big picture perspective of our planet. And so today, I want to put our conversation in the context of this bigger perspective. I want to put them in the context of the orbital perspective. And in doing so, certain trends, truths, and the path forward become clear.

Now, a little over 50 years ago, humanity as a whole had a collective out-of-body experience, an out-of-body experience that led to an inflection point between two human epochs. Now, the story of this inflection point begins on the winter morning December 21st, 1968 at the Kennedy Space Center in Florida. Atop the tallest, the heaviest, the most powerful rocket ever brought to operational status at the time,

the Saturn V sat the crew of Apollo 8. There was Commander Frank Borman, command module pilot Jim Lovell, and lunar module pilot Bill Anders. The aim of this mission was to become the first crude spacecraft in history to travel to and to orbit around the moon, and of course to return to Earth safely. But the inflection point came three days later when the crew of Apollo 8 came up from behind the far side of the moon on their fourth orbit and they realized something never seen before by human eyes. Commander Borman was the first to see the amazing sight

and he called out an excitement to the others taking a black and white photo in the process. In the ensuing scramble, Bill Anders took a more famous color photograph and it was all captured on the flight voice recorder. I wonder if they realized the significance of that moment. They had just become the first humans in history to see the whole planet hanging in the blackness of space and the first to capture this image for the rest of us. Now, this famous photograph is known as Earthrise,

and this is probably the most influential photograph ever taken. This image revolutionized how we see the world, how we see ourselves with a simple message that we are one people traveling on one planet towards one shared future. But unfortunately, the significance of this image has, or had, for the most part, been forgotten. But back in 1968, for a brief moment, the world was won. People from all over the world, including even in the Soviet Union, a nation that was locked

in a space race with the U.S. and a Cold War with the West, proclaimed this a monumental achievement for all of humanity. For a brief moment, the world rallied around the image of Earthrise. and this is Earth set. So you've probably all seen this photograph. It was taken about five days ago by the crew of Artemis II. Now our return to the moon

can serve as a second wake-up call. It could be a second opportunity to change how we see ourselves. Now, for Apollo 8, you have to realize that Apollo 8 was taken at the end of 1968. This was a year that was filled with much strife in the United States and most of the world,

the years saw political assassinations and massive unrest in streets and cities all around the world. And although the threats that we face today are somewhat different, we are living through at least equally chaotic times. Now, one of those assassinations in 1968 was Dr. Martin Luther King, Jr. But precisely one year before the Apollo-Aid astronauts were hurtling through space on their journey to the moon, Dr. King gave a sermon. He gave the Christmas sermon on peace, which I believe gives words to what Earthrise evoked.

It really boiled down for this, that all life is interrelated. We all caught in an inescapable network of mutuality tied in a single garment of destiny and whatever affects one directly, affects all indirectly. we aren't going to have peace on Earth until we recognize this basic fact

of the interrelated structure of all reality the interrelated structure of all reality this isn't a cliche this isn't a philosophy this is the reality of the world that we live in this is fact what will help usher in a new human epoch

is a greater understanding of the basic fact of the interrelated structure of all reality. So when my six-month mission was over, my two Russian crewmates and I climbed into our Soyuz spacecraft, we undocked from the space station, we did a couple laps around the planet. And as we crossed the south tip of South America, we turned the spacecraft around, we fire the engines, we entered the upper atmosphere. It was very similar to what we saw in Artemis 2 yesterday. We had this fiery, violent ride through the atmosphere at five miles a second. The parachutes opened, it threw us all over the place. We didn't

splash down in the soft Pacific Ocean. We smashed down into Kazakhstan. And I have to point out that that video is in slow motion. So we actually hit a lot harder than it looks. We hit so hard, in fact, that we bounced and we rolled and we flipped over. And when the capsule finally came to rest, my window was pointed down at the ground. And out of my window, I saw a rock, a flower, and a blade of grass. And I remember thinking to myself, I'm home.

And what was really cool about that thought is I was home, but I was in Kazakhstan. then. So, to me at that moment, home wasn't just Houston, Texas, where I lived with my family at the time, home was Earth. And our definition of that word, home has profound implications for how we problem solve, how we treat each other, how we treat our planet. And the other thing I realize is expanding the definition of the word home did not come with a requirement to forget where we came from, our national, our ethic, our religious, our organizational affiliations. It simply means seeing those things in the context of the bigger picture. And so in the context of the bigger picture, I want to thank all of you for what you're doing to help make life on our planet as beautiful

as our planet looks from space. You don't have to be in orbit to have the orbital perspective. And by working together, we don't have to accept the status quo on our planet. So thank you very much. I bet Yuri Gaguerra never imagined that all of these years later, people from across the world would be shouting his name and celebrating what his flight meant for humanity. But while we're celebrating Gagarin's achievement, there's something about his story that I think is totally worth knowing. Bruce Betts, who's our chief scientist, is here with this week's What's Up, and a lesser-known tale about what actually went wrong on that historic flight. Hey, Bruce. Hey, Sarah.

Man, it has been a lot of adventures this month. Like, I just got back from the Day of Action a few days ago, but now we're flashing back to this moment earlier this. month right after Artemis 2 dropped down and it was Yuri's night. It's just been a lot of space celebration recently. You're just a space party animal. Space party animal. So I've been going to Yuri's night for many, many years, but I was literally like this many years old when I found out that Yer Gagarin's flight was way more terrifying than I thought. I mean, going to space is scary. Going to space is the first person is terrifying. But then there were. was like a hardware malfunction

during the Vostok 1 mission and I had no idea about it. So I figured we should talk about it because that was extra surprising to me. Yeah, all sorts of fun fest of stuff. And plus they, I mean, it's not as surprising because Soviets tended to

hide any failures or try to. Right. So me not knowing about this was actually by design. Yes, it was. I mean, they hid the profile of the mission for several years, whether it fit the definition or not of first, I don't know, round trip to space, because they hadn't figured out how to land yet. And so he had to bail out at seven kilometers up and parachute down. But they hid that part until 71. At least that's when they

admitted it. And that was the part that worked. They just knew that didn't work. So those are courageous people to get in those spacecraft. But they had a generally, some genuine problems, anomalies, malfunctions, 10 seconds after the retrofire, the service module failed to separate from the reentry module, which is bad. That's bad. You don't really want to go through the atmosphere attached to your service module, but he did. The modules tumbled and spun violently, and I'm sure it was very fun and very calming. and then it was still attached by some wires,

but eventually, you know, good job going through the atmosphere because that burned up the wires and modules separated. And I like that Gagarin just in the process of all this said everything is okay. I mean, he said it in Russian, of course, during the gyrations because he didn't want to make noise. As he figured it wasn't dangerous. You know, that seems like that's obvious. It was probably more dangerous to upset the Soviet High Command.

How weird is that? It's like no matter what generation of astronauts you're from, it's like they're such calm people that even in situations like this, it'll be fine. So what if I'm spinning out? Yeah. Well, I mean, they chose everyone in that era was choosing test pilots who were built to be calm. It was the other really cool thing about Yuri's night this year is that

there were just so many people who had been to space, not just NASA astronauts or we had a Norwegian astronaut as well, but there were a lot of people that had been to space on commercial space flights. Did you count yourself because you sometimes seem like you've been in space? Nope, Sarah doesn't count yet. All right, yet. Oh, yeah. Well, I mean, that was a really fun thing about something that I think Frank White said in his talk about the overview effect was that essentially because of this new age of commercial spaceflight. like everybody on Earth is basically part of the astronaut core. I mean, most of us are still not going to go to space, but there's a chance and that chance is getting higher all the time.

And so, you know, I won't give up hope. You keep hoping. Believe me, we've all said we'd send you to space if we could. But, you know, if we could just make sure that the service module actually separates correctly and I'm not dragging things by wires in space, that sounds so terrifying. the man, he did it. That's so crazy. Yeah, I picture of the family like, are there any scissors around? Right. I always bring a pocket knife.

Okay, I'm good. I can cut those. Just reach outside my burning spacecraft and cut those. It'll be fine. Yeah, those guys were impressive. Seriously. I mean, they still are, obviously. But those early spacecraft were crazy.

shall we move on let's do it random space thick rewind rewind so the rings of Saturn they are ridiculously thin compared to their diameter

at least the vast majority of them when there's some strange part but even those parts so if the main rings of Saturn were as thick as a blue ray disk let's say if people still know

those look like. The Blu-ray disc would have a diameter of over 33 kilometers. No way. Yeah, Yahweh. Dude, that's... God. It's nuts. It's nuts.

That is nuts. Like, I remember when Cassini started dropping those readings about the actual thickness of Saturn's rings during those ring dives. And I remember thinking, like, wow, that's not at all what I expected. But when you put in that perspective, that's...

Those are really, really thin. Yes, yes, really, really thin. I mean, I believe on average they're around 10 meters thick and they're, you know, sizes of big countries and width. That was an odd way to say it, but you get the jam. Yeah, that's so cool. Everybody, go out there, look up the night sky and think about if ring diving, the thin ring,

of Saturn, then how long would it take for the service module wires to burn through? Thank you. Good night.
