Student A: So, the final question is, do we really have to go to Mars? I mean, we’d be spending such enormous resources and risking people’s lives. Is it worth it?

Student B: That’s a reasonable question. But experts say there are two main benefits to Martian exploration: practical benefits and a sense of shared destiny for all of humanity.

Student C: What kind of practical benefits are we talking about?

Student B: Well, they’re economic, educational, and political. Space travel can stimulate industries, and it draws people into careers in science and engineering. It can also raise a country’s status on the world stage because space exploration is often a global collaboration.

Student D: I see. So it’s not just about the immediate benefits, but also about the long-term impact on society and the economy.

Student A: Right, and then there’s the whole idea of a shared human destiny. Experts say that, with the resources on Earth being depleted, we need to find ways to survive. Mars could be a step toward a future where humanity has a presence on another planet.

Student C: That sounds like a really big goal. It’s not easy, but maybe it’s worth it.

Student D: I agree. I remember a scientist involved in a Martian project saying, “You can’t really measure the value of something like this. If money were the only concern, everyone would just study business. But people also want to give meaning to their lives. That’s why dreams and passion are so important.”

Student A: So, it’s not just about the money. It’s about having a purpose, a dream that drives humanity forward.

Student B: Exactly. It’s about more than just survival—it’s about pushing the limits of what we can achieve as a species.

정현범: Hey, did you know that humans first landed on the moon in 1969? Apollo 11 was the spacecraft that made it happen. It’s crazy to think about how long ago that was!

정나은: Yeah, I read about that! It took over 50 years before anyone seriously started thinking about going to Mars, right? It’s kind of wild how long it took.

손연우: That’s because Mars is way farther from Earth than the Moon is. I guess that makes it a lot more difficult to reach, and we didn’t know as much about it back then.

정현범: Exactly. But, with all the advancements in science and technology over the last few decades, people are finally starting to plan missions to send humans to Mars.

정나은: That’s so cool! A lot of countries are involved in those projects now, like NASA and even private companies like SpaceX.

손연우: Yeah, but even though they’ve made progress, there are still huge challenges. It’s not just about getting there, but also surviving and staying there long enough to study the planet.

정현범: True, there’s so much more that needs to be figured out. But at least it’s exciting that we’re finally making steps towards it after all these years!

김준서: Health is a big issue when going to Mars, right? Our bodies react differently in space.

황세훈: Yeah, on Earth, gravity pulls everything down, but in space, that doesn’t happen. Our bodies have to adjust.

박효담: Right, and the heart works harder because of weak or zero gravity. Plus, muscles and bones weaken from weightlessness.

김준서: Astronauts exercise a lot to counter that. They also use drugs and artificial gravity. We’ll have to do the same on Mars.

황세훈: And then there's cosmic radiation. Without Earth’s protection, it can damage our DNA and increase cancer risks.

박효담: To protect against that, they’ll cover space vehicles with radiation-blocking materials and build underground shelters on Mars.

홍동건: Hey, have you ever thought about how tough it would be to live on Mars? I read that it's way more complicated than being on the ISS.

한태인: Yeah, I heard that too. For starters, we'd need to extract water from ice, and the soil there isn't great for farming. Plus, Mars has weaker gravity, which could mess with plant growth.

박재현: Exactly. That's why experts think successful farming on Mars could take decades or even centuries to achieve.

홍동건: In the meantime, they've come up with the idea of using 3D food printers. These can make things like pizza and bread using proteins and carbs from sources like insects and leaves.

한태인: That's pretty innovative. I read that a NASA scientist predicts there will be about 25 to 50 basic food items. They're not aiming for gourmet meals, just healthy and nutritious ones.

박재현: And for oxygen, plants might help produce it, using recycled human waste as nutrients. But until we have enough plants, NASA plans to use special machines to convert carbon dioxide from the Martian air into oxygen.

홍동건: It's fascinating how they're planning to use the resources available on Mars to support human life.

한태인: Absolutely. It shows how much thought and innovation is going into making life on Mars possible.

박재현: I can't wait to see how these plans develop in the coming years. Living on Mars might become a reality sooner than we think!

박연진: Hey, have you ever thought about what humans need to survive on Mars?

백호진: Yeah, obviously we’d need water, food, and oxygen to live there.

이수아: We already know quite a bit about Mars, but there’s still so much more to learn. One of

the most exciting discoveries is water.

김희은: Right! NASA scientists confirmed that Mars once had more water than even the Antarctic

Ocean. Some of it is still trapped in the polar ice caps.

박연진: That’s crazy! Are they trying to figure out how to get the water out of the ice?

백호진: Yep, scientists are working on effective ways to extract it. But water isn’t the only thing we

need — we also have to think about food.

이수아: Growing food on Mars is tough, but they’ve tested special farming systems on the

International Space Station. We might be able to use those.

김희은: Still, space farming isn’t easy. You have to carefully manage things like gases, water, and soil to grow plants properly.

윤서영: Did you guys know that Mars is more than 100 times farther from Earth than the moon?

심혜원: Yeah, which is why getting there needs some serious hardware—like powerful rockets and super fast computers.

임서윤: That’s why NASA is already designing a new generation of spacecraft to handle the trip.

김아론: Even then, it’s not easy. A round trip to Mars takes a long time—about six months just to get there.

윤서영: And even when Mars is closest to Earth, the whole trip would still take at least a year.

심혜원: The problem is, today’s rockets can’t carry enough fuel for a journey that long.

임서윤: Scientists are working on ways to solve that, but it’s still a huge challenge.

김아론: I read that a European company actually has a plan to send four astronauts on a one-way trip to Mars to start a colony!

윤서영: Whoa, really? That sounds intense. 심혜원: Yeah, and the plan is to send more people every two years to grow the colony. 임서윤: It's kind of exciting but also risky.

김아론: For sure. We’ll have to wait a few years to see if it works.

김건우: Did you guys know that Apollo 11 was the first spacecraft to land humans on the moon? That happened back in 1969.

김수아: Yeah, I remember learning about that. But why did it take so long for people to start thinking about going to Mars?

정하현: It’s mostly because Mars is much farther from Earth than the moon. Plus, we didn’t know much about it back then.

김건우: That makes sense. So it took almost half a century before anyone seriously considered a manned mission to Mars.

김수아: But now that science and technology have advanced a lot, there are actually projects aiming to land humans on Mars.

정하현: Right, and a lot of industrialized countries are involved in those projects. Scientists are making progress, but there are still major challenges to overcome.

# data[].attributes.body
이강현: Do we really need to go to Mars? It’s expensive and risky.

황은율: Experts say yes—for practical reasons and our shared future.

이유림: What kind of practical reasons?

황은율: It boosts the economy, inspires science careers, and improves a country’s global status.

양이안: And it encourages international cooperation through joint missions.

이강현: Okay, but what’s this “shared future” idea?

이유림: Earth’s resources are running out. We need to find new places to live.

양이안: Mars could be the first step. It’s not easy, but it’s a meaningful goal.

황은율: Like one scientist said, “If money were all that mattered, we’d all study business. But we also need dreams and purpose.”

이강현: True. It’s about more than money—it’s about hope for the future.

C 백민규: But even with that kind of tech, a round trip to Mars would be really tough. Just getting there takes about six months.

D 강은주: And since the spacecraft can’t carry enough fuel for such a long journey, a round trip isn’t really possible with today’s technology.

A 강은주: That’s why scientists are trying to solve the fuel problem. But in the meantime, a European company came up with a different idea.

B 이은서: Are you talking about that one-way mission? The one where four astronauts go to Mars and don’t come back?

C 백민규: Yeah, that one. Then every two years, new crews would join them to build a colony.

D 강은주: It sounds exciting, but also kind of scary. We’ll have to wait a few years to see if it actually works.

최정우 Have you guys ever thought about how hard it would be to farm on Mars? It’s way more complicated than doing it on the ISS.

김경빈 Yeah, I heard that on Mars, they not only have to recover water from ice, but they also have to deal with poor soil and weak gravity. That sounds like a huge challenge.

이도현C: Exactly. That’s why experts think successful farming there could take decades or even centuries!

박건민 So what would people eat until then? They can't just survive on snacks.

최정우Actually, NASA is working on 3D food printers. They can use proteins and carbohydrates from things like insects and leaves to print stuff like pizzas and bread.

김경빈: That sounds weird but cool! I read that a NASA scientist said they’re expecting around 25 to 50 basic food items.

이도현Yeah, and they’re not aiming for fancy restaurant meals—just healthy and nutritious food to keep people alive and well.

박건민 And what about oxygen? People can’t breathe Martian air.

최정우They might use plants to produce oxygen. But since there won’t be enough plants at first, they’re also planning to use machines that convert carbon dioxide into oxygen.

김경빈That’s smart! They even want to recycle human waste to help grow the plants. It’s like building a little Earth up there.

양건형

김대영: Hey, have you ever thought about how living on Mars could affect our health?

건형: Yeah, I read that our bodies work really differently in space. Like, on Earth gravity pulls fluids down, but in space that doesn’t happen.

대영: Right, and because of that, the heart has to work harder, especially in zero or weak gravity like in space or on Mars.

건형: That sounds exhausting. Plus, weightlessness weakens your bones and muscles over time.

대영: That’s why astronauts on the ISS exercise a lot. They even use drugs and artificial gravity machines to help out.

건형: I heard similar stuff would be used on Mars too. It’s kind of cool how they plan for everything.

대영: But I think the scariest thing is cosmic radiation. Without Earth’s atmosphere and magnetic field, we’re totally exposed.

건형: Yeah, and that radiation can mess with your DNA and raise your risk of cancer. It’s serious.

대영: So they’re planning to cover space vehicles with radiation-blocking materials and even build shelters underground on Mars.

건형: Makes sense. Living on Mars is not just about getting there—it’s about staying safe too.

성현: Hey, guys, have you thought about how tough it'll be to live on Mars? They say the soil there is bad, and the gravity is super weak.

건우: Yeah, it sounds crazy hard. How are they gonna grow anything with bad soil and weak gravity?

은준: I read they're planning to use 3D printers to make food! Like, they can print pizzas and bread using proteins from insects and stuff.

건: But will that be enough? I mean, printing food is cool, but what about oxygen?

성현: They're saying they'll use plants to make oxygen. It'll take time, though, until they can grow enough.

건우: What about recycling? Can they use, like, human waste to help the plants grow?

은준: Yeah, they're thinking of recycling waste to give nutrients to the plants. They've got these machines to turn Martian air into oxygen, too.

건: So, basically, it's gonna be a long journey before they figure out how to live there comfortably?

성현: Seems like it. But hey, at least they're starting with basic, healthy meals. No fancy restaurants on Mars yet!

주사랑: Do you guys really think we need to go to Mars? It costs so much and it’s super risky.

고은아 : Yeah, it’s risky, but there are actually some practical benefits. Like, space exploration can boost the economy and get more people interested in science and engineering.

고경민: True, and don’t forget that it can also help countries work together. A space program makes a country look pretty powerful too.

주사랑: I get that, but still... spending all that money? Is it really worth it?

고은아 : Well, there's also the whole idea that Earth’s resources are running out. So maybe going to Mars is part of making sure humans survive long-term.

고경민: Exactly. If we run out of stuff here, we’ll need a backup plan. Mars could be that plan.

주사랑: I guess when you think of it like that, it’s more than just science—it’s about our future.

고은아: Yeah, and one scientist even said you can’t really measure the value of going to Mars. It’s about dreams and giving life meaning, not just money.

오다인: Right! NASA confirmed that Mars used to have more water than the Antarctic Ocean. That’s crazy to think about.

정태은 : And some of that water is still on Mars today. It’s locked up in the polar ice caps, and scientists are working on ways to get water from that ice.

정단이:Water is so important, but after that, the next big thing is food. We’ll need to find ways to grow food on Mars, which isn’t easy at all.

김양지: And some of that water is still there—it’s locked up in the polar ice caps. Scientists are working on ways to get it out and use it.

천형욱: Water’s just one part. We also need food to live on Mars, and farming there is a whole new challenge.

문종훈: Totally. They’re thinking about using special farming technologies—ones they’ve already tested on the International Space Station.

최락규: But growing food in space isn’t easy. Plants need careful control of things like gases, water, and even dirt.

최영은: Hey, did you guys know that humans first landed on the moon back in 1969 with Apollo 11? That was such a huge moment in history.

신홍준: Yeah, I remember reading about that. But it’s kind of surprising that even after all these years, we still haven’t landed anyone on Mars.

이승재: That’s true. I think part of the reason is that Mars is just so far away from Earth. It’s not as simple as going to the moon.

최영은:Exactly. And for a long time, we didn’t really know enough about Mars to even plan a mission like that.

신홍준: But recently, things have started to change, right? Science and technology have come a long way over the past few decades.

이승재: Yeah, now a bunch of industrialized countries are getting involved in Mars projects. Scientists are definitely making progress, but I heard there are still some huge challenges ahead.

동혁: Did you guys know that Mars is more than 100 times farther from Earth than the moon? Reaching it isn't easy at all.

유진: Yeah, that's why they need really serious hardware, like super powerful rockets and incredibly fast computers.

진혁: I heard NASA is already working on that. They’re designing and building a new generation of spacecraft for the mission.

예준: Even with those rockets, getting to Mars and back is tough. Just one way takes about six months!

동혁: And that’s when Mars and Earth are closest in their orbits. A round trip would take at least a year.

유진: The problem is, today’s rockets can’t carry enough fuel for a journey that long.

진혁: That’s why scientists are trying to figure out new ways to solve the fuel issue.

예준: Meanwhile, a European company actually wants to send four astronauts on a one-way trip to Mars. That’s wild!

동혁: I heard they’re planning to send more crews every two years to build a colony there.

유진: It sounds exciting, but we’ll have to wait a few more years to see if it really happens.

# data[].attributes.body
김태규: Do we really have to go to Mars? I mean, think about how much money and resources it takes, not to mention the risks to people’s lives.

이승기: Yeah, that’s a good question. But experts say there are two main benefits of Martian exploration: practical benefits and the idea of a shared destiny for all of us as humans.

박예은 : What kind of practical benefits are we talking about?

이승기: Well, space travel can lead to economic, educational, and political gains. It stimulates industries, creates jobs in science and engineering, and even raises a country’s status globally when they participate in space programs.

신성훈: That makes sense, but isn’t the bigger picture about our survival? The Earth’s resources are running out, and we might need to find another place to live.

김태규: So you’re saying exploring Mars is more about saving humanity? That’s kind of a big step.

박예은: Yeah, it’s about our shared destiny. If we can establish a human presence on another planet, it might be our way to survive when Earth’s resources are used up.

이승기: Exactly. It’s not going to be easy, but it’s a dream worth pursuing. It’s like what one scientist said, "You can’t really measure the value." If money were the only concern, everyone would just go into business. But we need something bigger, something meaningful.

신성훈:So, it’s not just about money. It’s about passion, dreams, and giving meaning to our lives as humans.

김태규: I get it now. It’s not just about the practical side, but about what it means for humanity as a whole. Maybe it's worth the risk after all.

임수연: Have you ever thought about what happens to our bodies when we go to Mars?

양현지: Yeah, it’s actually pretty complicated. Our bodies work differently in space because there’s no gravity like we have on Earth.

김하은: Right! On Earth, gravity pulls fluids downwards, but in space, that doesn’t happen. So the heart has to work harder, especially during space travel and on Mars.

장하림: And don’t forget about the weightlessness. It weakens our bones and muscles. That’s why astronauts on the ISS have to do a lot of exercise.

임수연: They also use drugs and spinning devices to create artificial gravity. I think they’ll use similar things on Mars, too.

양현지: But the biggest danger might be cosmic radiation. Without Earth’s atmosphere and magnetic field, we’re exposed to it out there.

김하은: That kind of radiation can damage our DNA and raise the risk of getting cancer.

장하림: That’s why scientists plan to use special materials to block radiation on space vehicles and build shelters underground on Mars. Sounds like living there won’t be easy

# data[].attributes.body
현서: So, imagine living on Mars… it's way harder than it sounds.

수아: Definitely. Just getting water would be a mission. They’d have to melt ice from beneath the surface.

현수: And even if they get the water, the soil there isn’t good at all. Plus, Mars has low gravity, so growing food would be super difficult.

나린: That’s why NASA’s thinking about using 3D food printers. They’d use proteins and carbs from things like insects and leaves to make basic stuff—like pizza and bread.

현서: Wait, did you say insects? We’d be eating bug-pizza on Mars?

수아: Yeah, kind of. But a NASA guy said it won’t be anything fancy—just 25 to 50 simple, nutritious meals to survive on.

현수: And oxygen? That’s another challenge. They’ll try using plants, but until there are enough of them, they’ll rely on machines to turn carbon dioxide into oxygen.

나린: Oh, and they’re planning to recycle human waste to help feed the plants. It sounds weird, but it actually makes sense in a closed system like that.

# data[].attributes.body
오선향: Hey, have you guys ever thought about what it would really be like to live on Mars? I mean, not just the adventure part, but how it might affect our health?

모은결: Yeah, that’s a serious issue. Our bodies actually behave really differently in space. For example, on Earth, gravity pulls our bodily fluids downward, but that doesn’t happen in space.

신지우: Right, and that means the heart has to work harder during space travel—and even on Mars—because of the weak or zero gravity.

구은지: I also heard that being weightless weakens our bones and muscles. That’s why astronauts on the ISS have to exercise a lot.

오선향: Exactly! And they also use drugs and even spinning machines to create artificial gravity. I guess they’ll do the same on Mars to help with that.

모은결: But there’s something even more dangerous—cosmic radiation. Without Earth’s air and magnetic field, we’re exposed to it, and it can damage our DNA and raise our chances of getting cancer.

신지우: That sounds terrifying. So how are they planning to protect people from that?

구은지: They want to cover space vehicles with special materials that block radiation and build shelters underground on Mars. That should help keep people safe.

명승현: "But even with those rockets, a round trip to Mars would take at least a year. Six months just to get there!"

이예린: "And current spacecraft can't carry enough fuel for such a long journey. That's a huge problem."

박세아: Have you guys ever thought about how tough it would be to live on Mars? It’s way more complicated than being on the ISS.
송유준: Yeah, I read that one of the biggest issues is getting water. They’d have to recover it from ice, and even then, the soil is really poor quality.
고은호: Not to mention Mars has weak gravity. That could affect how crops grow. So farming there could take decades, maybe even centuries to work properly.
유지아: In the meantime, people might have to rely on 3D food printers. They can actually print stuff like pizza and bread using proteins and carbs from things like insects and leaves.
박세아: That sounds weird but kind of cool. A NASA scientist said they expect to have around 25 to 50 basic food items available.
송유준: He also said they’re not aiming for gourmet meals, just healthy and nutritious food. Makes sense, right?
고은호: But what about oxygen? I heard that plants might be used to produce it, and even human waste could be recycled to help them grow.
유지아: Until there are enough plants to make enough oxygen, NASA wants to use machines to turn carbon dioxide in the Martian air into oxygen. It’s all pretty wild!

김지민: Do we really have to go to Mars, spending so much money and risking people’s lives? It just seems like a huge gamble.

정어진: That’s actually a fair question. But experts say Martian exploration can bring two kinds of benefits—practical ones and something deeper, like a shared human destiny.

정승재: Yeah, the practical benefits are pretty interesting. Space travel helps the economy, encourages education, and even boosts politics. Like, it creates jobs and gets more people into science and engineering.

양희성: Not to mention, countries often work together on space programs because they’re so expensive. But having your own program can also boost your reputation around the world.

김지민: Okay, so it helps countries look good and supports science. But what about that “shared destiny” part

정어진: That’s about how we’re using up Earth’s resources. If we want humanity to survive long-term, we might need to find a way to live somewhere else, like Mars.

정승재: Right, it’s not just about escaping Earth. It’s about dreaming big—seeing Mars as a step toward living on other planets.

양희성: A scientist once said, “You can’t really measure the value. If money was all that mattered, we’d all study business. But we need meaning in life. That’s why dreams and passion matter to us.”

김지민: Huh... I never thought about it that way. Still, I wonder—do we really have to go to Mars?

최현서: Yeah, that was Apollo 11, right? It’s crazy to think it’s been over 50 years since then.

김장수: And we’re only now starting to seriously talk about going to Mars. That’s such a long wait.

서유현: Well, Mars is much farther from Earth than the moon. That’s probably why.

최현서: Plus, we didn’t know much about Mars for a long time. It wasn’t exactly an easy mission to plan.

김장수: True, but now that science and technology have advanced, actual Mars landing projects are starting.

서유현: I heard that many developed countries are getting involved in those efforts.

홍수빈: For sure. I heard that the most exciting discovery on Mars so far is water. It turns out Mars actually had more water than even the Antarctic Ocean!

박대원 : Seriously? That’s wild. I read that some of the water is still there, locked up in the polar ice caps.

이병철 : Scientists are trying to figure out how to get water out of that ice. That would be super important for survival.

최예진: Water is one thing, but we’d also need food. Growing food on Mars would be a huge challenge.

홍수빈: Yeah, but there’s hope. They’ve already tested some special growing systems on the International Space Station.

박대원 : Even with that, farming in space isn’t easy. You have to carefully manage gases, water, and soil just to grow plants.

황수민: I know, right? But Mars is so much farther from Earth than the moon. Plus, we didn’t really know much about it back then.

윤형석: Good question! We’d need special farming technologies. There’s a growing system they’ve tested on the International Space Station that might work.

노현서: I’ve heard farming in space is really tricky. Plants need careful control of gases, water, and even the kind of dirt they grow in.

Hey, have you guys thought about how hard it would be to live on Mars?

김유진:

Yeah, I read that it’s even more difficult than living on the ISS. Like, they have to find a way to recover water from ice.

강서진:

Right, and the soil on Mars is super poor. Plus, the gravity is a lot weaker than on Earth, which makes farming really tough.

2609박경모:

That’s why scientists think it could take decades—or even centuries—to actually grow food there.

홍성현:

Until then, they’re planning to use 3D food printers. Pretty cool, right? They can use proteins and carbs from insects and leaves to print stuff like pizza and bread!

I saw that too. A NASA scientist said they might have about 25 to 50 basic food items. Nothing fancy, but at least the meals will be healthy and nutritious.

But food’s not the only problem. What about oxygen? We can’t survive without it.

2609박경모:

They’re thinking of using plants to make oxygen eventually, and even recycling human waste to feed the plants.

Until there are enough plants to do that, NASA has these special machines that can turn the carbon dioxide in Mars’ air into oxygen.

김시우: Have you guys ever thought about what it would be like to live on Mars? I read that our bodies would work really differently out there.

서하늘: That sounds intense. So does the heart have to work harder in space?

조상진 : Exactly! The heart needs to work harder because of the weaker or zero gravity. And it’s not just the heart—our bones and muscles can weaken in space too.

김시우: That’s why astronauts on the ISS do so much exercise, right? They also use drugs and some kind of spinning device to create artificial gravity.

주하나: Okay, but what’s this whole “shared destiny” thing about?

김서윤: It’s about survival, really. Earth’s resources are running out, and we might not have enough to support future generations. We need to explore other options, like Mars, to make sure humanity has a future.

윤현찬: So it’s kind of like insurance for humanity, right? Even though it’s risky and expensive, it’s something we have to consider seriously.

김다은: One of the scientists working on a Mars project said something that stuck with me — that you can’t always measure the value of something like this with money. If that were the case,  we’d all just study business!
