00:00Picture this. You're planning your dream holiday, but instead of going to a tropical beach or a
00:05bustling city, you're thinking about going to space. Imagine yourself floating, weightless,
00:13looking down at Earth from a whole new perspective. The beauty and wonder of our planet become even
00:19more evident when you're viewing it from a distance. And now, this dream can come true.
00:24Yes, you heard that right. Space tourism. Space tourism is something that has fascinated people
00:32for generations. This idea has been around for almost 20 years. We've seen it in movies and read
00:39about it in stories. But now, thanks to advancements in technology, it's finally becoming a reality.
00:46The first space tourist was a businessman named Dennis Tito. He visited the International Space
00:51Station in 2001. Sounds incredible, but here's the catch. Tito's trip cost a mind-boggling 20 million
01:00dollars. That's a lot of money, and it made space travel seem like a dream that only the super-rich
01:07could afford. And it's true that space tourism can be quite expensive. But a lot of time has passed
01:13since that day. And now, space tourism is becoming more attainable for people who aren't billionaires.
01:20Of course, the industry is still in its early stages, but the demand for it is skyrocketing,
01:27pun intended. Experts believe that it will continue to grow at an incredible rate of around 40% every
01:34year from 2023 to 2030. So, with all this in mind, let's talk about what awaits us in the near
01:41future.
01:42There are different types of space tourism. First up, we have suborbital spaceflight. It's the trip
01:49where you reach an altitude of over 300,000 feet, which is way higher than any airplane can go. In
01:56fact,
01:57it's so high that you cross a special line called the Karman Line, which marks the boundary of outer
02:03space. How cool is that? So, it's basically like a quick jump into space and back. So, let's talk a
02:11bit
02:11more about suborbital spaceflight. Imagine you want to go on vacation to Sydney, but you live in London.
02:18Normally, it would take you about 22 hours to get there by plane. That's a really long time to sit
02:24on a plane. But guess what? Scientists and engineers are working on a new way of traveling that could
02:30make the journey from England to Australia super fast and exciting. Suborbital space trips could be
02:37used for quick travel between different cities on Earth. Instead of flying in a regular airplane,
02:42you would hop on a spacecraft that can go really, really fast. According to a recent study, in the
02:49near future, it might be possible to fly from London to Sydney in less than two hours. Just imagine how
02:57amazing that would be. You would zoom up into space, see the Earth from above, then come back down in
03:04no
03:04time at all. What an adventure! This study, conducted by the UK's Civil Aviation Authority, was all about
03:12understanding how our bodies react to trips outside Earth's atmosphere. To figure this out, the researchers
03:18needed some brave volunteers. They recruited 24 healthy people between the ages of 32 and 80.
03:26These volunteers were taken to a special training facility called an RAF centrifuge in Cranwell.
03:33A centrifuge is a big machine that looks like a giant spinning chair. The volunteers were sat in
03:39there to experience a simulation of space flight. They were spun around, and their bodies felt the pressure
03:45and changes in gravity that happen when you go into space. Almost everyone handled the simulation
03:52pretty well, and quickly returned to normal. One person even briefly lost consciousness, but it was
03:58because of the gravitational forces, and they recovered soon after. Now this study found some surprising
04:04things. Many people think that you have to be really fit and young to handle space flights. But the research
04:12showed that older people can actually cope better with all this gravity craziness. So even if we don't
04:18develop space tourism in the next decade or two, you'll still have a chance to visit space, even when you
04:24get old. Right now, there are two big players in the suborbital spaceflight game, Virgin Galactic and Blue Origin.
04:33Both of these companies have rocket-powered systems that can take up to six passengers on a thrilling ride.
04:40Virgin Galactic has already had four successful flights, but they recently ran into some financial trouble.
04:47On the other hand, Blue Origin has flown 32 passengers on their new Shepard rocket. The catch is pretty
04:54obvious. Right now, space tourism is super expensive. Companies can charge a whopping 350,000 pounds per seat for
05:03these flights. But don't worry, things are about to change soon. Experts believe that space tourism will
05:10grow in the coming decades. It will be kind of similar to what happened to airplanes. Right now, the cost
05:17of
05:17a quick trip to space is very high. But as time goes on, the prices will go down. Eventually, space
05:25tourism
05:25will become more affordable and accessible to people all around the world. That means not just our children,
05:32but many of us will have a chance to experience the wonders of space. As technology advances, we might even
05:40be
05:40able to plan rocket-powered holidays in the future. Can you imagine telling your friends that you went on a
05:47vacation to space? What a flex! And now, let's talk about orbital space flight. This is the real deal,
05:55where you get to spend more time in space. Instead of just a few minutes, you can spend anywhere from
06:01a few
06:01days to over a week up there. And we're not talking about a measly 300,000 feet anymore. We're talking
06:09about
06:09going over 1.3 million feet high. So whether you're up for a quick jump into space or a longer
06:16adventure
06:16orbiting our planet, space tourism has something for everyone. Sky is no longer the limit. But space
06:25tourism isn't all fun and games. There are some challenges we need to consider too. First off,
06:31let's talk about the environment. Launching spacecraft and rockets takes a lot of energy and can create air and
06:38noise pollution. This can seriously harm our atmosphere. We don't want to trade a cool space
06:44trip for a damaged planet, right? Next, there's the issue of safety. Space travel is still risky.
06:51And accidents can happen. Even with safety protocols in place, there's always a chance of something going
06:59wrong. And if it does, the consequences could be really, really bad. Yikes! Space debris is another
07:07concern. Every time a spacecraft is launched, it leaves behind debris that can stay in orbit for
07:13a long time. As more launches happen, the amount of debris keeps growing. This can cause problems for
07:20other spacecraft, and even small pieces of debris can cause damage. Space travel also requires a lot of
07:27resources like energy, fuel, and materials. Using up these resources too quickly could have long-term
07:34consequences for our planet and future generations. We need to make sure we're not depleting everything
07:40in our quest for space exploration. Oh, and let's not forget about all the legal stuff. The rules and
07:47regulations for space tourism are still evolving, and it's not always clear who should be responsible if
07:54something goes wrong. Plus, there are concerns about how space tourism might affect international space
08:01laws and treaties. We don't want legal chaos in the final frontier. And finally, to achieve our dream
08:07of taking spaceships like planes, we'll need better infrastructure and logistics. We'll need to build more
08:14spaceports where spaceships can take off and land. But don't worry, scientists are actively working to solve
08:21these problems. Remember, it's not just us who are excited about space tourism. Even governments are joining the fun.
08:28Many countries are investing in space tourism too. It's a global phenomenon. So even though there's still
08:35a lot to develop in this industry, it's pretty obvious that the aviation industry might go through
08:41a big revolution. Traveling long distances would become much quicker and more exciting. And judging by
08:49the way development is going, the first big breakthrough in this area will be made in North America.
08:55So, get ready for a new era of travel. What an exciting time to be alive, right? The universe is
09:02calling, and it's time for us to answer. Stay tuned!
09:06We often see humans living on other planets like Mars. Colonizing our solar system and beyond has long
09:13been a dream of humankind. The idea of humans going to space dates back to at least 1610. A German
09:21astronomer named Johannes Kepler wrote to an Italian astronomer named Galileo. Kepler said that we could
09:28create ships to travel in space and even create maps of the stars. People got more excited about space
09:35during the famous space race. NASA was created in the 50s. They did many cool things like sending space
09:42stations, Mars rovers, and exploring other planets. All this made space travel seem more real.
09:50Today, we've developed to the point where we finally discuss the possibility of space tourism.
09:55We're already sending regular people into space. Only very rich people, of course. But many believe that,
10:03in just a few decades, space tourism will become normal. We'll be able to fly to Earth's orbit and back,
10:10as if on some kind of tour. Spaceships will replace airplanes, and it will only take two hours to get
10:17from
10:17Australia to England. And finally, we'll begin to travel to other planets in our solar system. Some
10:24scientists even believe we'll have colonies on the Moon or Mars by the 2060s. In the future,
10:30we could colonize not only Mars, but some of the moons, like our own, Ceres, Titan, and others.
10:37But the thing is, why do we even want to live on other planets? Surprising question, huh? Sure, the answer
10:47might seem obvious at first glance. Humans want to learn about space and other planets. This curiosity
10:54is what led us to other big discoveries like going to the Antarctic and the Moon. Next, safety, of course.
11:01Humans have a moral duty to ensure our survival. Colonizing space could protect us from disasters
11:07that might wipe out life on Earth. Plus, by settling space, we improve our chances of survival
11:14and fulfill a moral obligation to do so. Besides, with Earth's overpopulation, colonizing other planets
11:21could relieve the strain on our home planet. Another thing is, colonizing a planet means living there
11:27and using its resources. And let me tell you, there are lots of resources in space.
11:34Our solar system alone has things to use for fuel, like Titan. Space colonization could bring us clean
11:41energy, access to new materials, new technologies, and so on. The more we colonize space and learn about it,
11:48the more we could benefit humanity, more technology, more exploration, more innovation, and so on.
11:56History also says explorers are way less likely to get into fights. Expanding and exploring,
12:03scientists claim, keeps us busy with cool discoveries, growth, and research. The more we explore,
12:10the less we're stuck with our earthly problems. But on the other hand, not everyone is interested in going
12:16to space. And maybe colonizing space isn't as good an idea as it seems. First of all, is it even
12:24possible?
12:25Some people say that living in space is just too far-fetched. You might have heard about
12:30terraforming. Terraforming basically means changing and improving the planet however we want,
12:36as if we were in some character maker in a video game. Sounds great. In theory. In reality,
12:43terraforming Mars, for example, could take hundreds of years and cost millions of dollars,
12:47according to experts. Colonizing our moon could cost an unimaginable 104 billion dollars. It's seven
12:56times NASA's yearly budget. And that's not even counting the earthly costs. But the biggest,
13:03most important question is, is it really that cool to live in space though? Space isn't your cozy home at
13:10all. Most celestial bodies are radiation hotspots, all because of the solar winds. Imagine a wind so
13:19fierce that it can strip planets of their very atmospheres. Our sun is a real danger to each planet
13:26in the system. Yes, including our own Earth. Stars are crazy powerful. They shoot out charged particles all
13:34the time. These particles can zoom around at incredible speeds, going up to five million miles
13:41per hour. These gusts of particles can leave an entire planet all barren. Poof. No more life-sustaining
13:49air. The water on the planet would evaporate, then freeze. The temperature would plummet to very chilling.
13:56And even daytime skies would be as black as night.
14:00Lucky for us, Earth has an amazing shield called a magnetosphere. It protects us from these space
14:07winds. But scientists are studying these winds to help us find other friendly planets out there.
14:13By checking out stars' properties, gravity, and magnetic fields, we can see if their planets can truly host
14:21life. And it's very hard to find a planet that isn't showered by radiation all the time.
14:26It has to have a very thick atmosphere, like on Earth, to prevent this from happening.
14:33Unfortunately, we haven't discovered any planets like this so far. Which is why living in space would
14:39mean dealing with crazy health problems. Temperatures and radiation are just the beginning. What about
14:45muscle loss, troubles with vision, and many other things? Humans are way too vulnerable for that.
14:52Robots are more suited for space exploration due to its hostile conditions.
14:57Let's take Mars for example. The red planet is freezing and very uninviting. In fact, the Earth could
15:04face almost anything, even mega problems, and still be better than Mars. Mars is a desert with barely any
15:12water, very far from the idea of a dream home. Let's imagine that the Earth's air get polluted. Mars still
15:19wouldn't be better. The air there is super thin and 96% carbon dioxide. Earth's air is a cakewalk compared
15:27to that. Or even if a huge asteroid crashes into Earth, we're still better off here than on other
15:33planets. It might even be a pretty big asteroid, like the one that wiped off the dinosaurs.
15:39This event was absolutely catastrophic, plunging the Earth into utter chaos. It created a massive crater
15:48called the Chicxulub crater. The impact led to massive fires, tsunamis, and a lot of dust and debris flying
15:56into the sky. The dust and debris blocked out the sun for a long time. Can you imagine what happens
16:03when
16:03there's no sunlight at all for a while? Everything got really cold and dark. This darkness and coldness
16:10affected plants and animals. Without sunlight, plants couldn't make food through photosynthesis,
16:16and that meant many animals lost their source of food. And these were only short-term consequences.
16:22Of course, many species became extinct because of that. But even with all that, 25% of species managed to
16:30survive somehow. If this same asteroid had hit Mars, the outcome would have been much worse. Mars doesn't
16:38have enough things like water and air to support life like Earth does, so the consequences would be way
16:44harsher. Actually, the Earth survived not one, but five mass extinctions. And life still managed to thrive
16:53on our planet, even after all that. As you can see, it's almost impossible to make the Earth
17:00completely inhabitable. Our planet will always be the most habitable place compared to anywhere else
17:06in our solar system. Unless we do something extremely insane. Which is why we need to protect it.
17:14Here we come to the famous, the Earth's in trouble argument. If something bad happens to our planet,
17:21why not focus on fixing it instead of flying away? Critics argue that if we can't take care of Earth,
17:27we shouldn't spread our problems to other planets or moons. Are we really capable of responsibly
17:33colonizing other worlds if we can't even manage our own? Plus, there's still so much to explore even
17:39on our own planet. Humans haven't even lived in Antarctica or under Earth's oceans yet. Are we sure
17:46we're ready for worlds that are even more extreme than that? So, even if Earth gets into trouble,
17:52we shouldn't just ditch it. We have to work together and create safe zones. It would be a big challenge,
17:59sure, but it's still way more doable and cheaper than building space colonies. Of course,
18:05the idea of humans living in space and traveling to other planets is very exciting. But we should never
18:10forget our sweet home. And we should remember that life isn't science fiction. We should use our technology
18:17rationally and focus on making the Earth safer and better. And what do you think about it?
