  • Imagine living on the Moon.

  • You'd have the best view of Earth.

  • You'd enjoy bouncing around in zero gravity,

  • And living your life as an astronaut explorer.

  • Doesn't that sound nice!

  • Except living on the Moon won't be like this at all.

  • Let's make this clear,

  • just like America did in 1969,

  • humans will land on the Moon again

  • in the next decade.

  • Only this time, it's expected to be more permanent.

  • What's less clear

  • is exactly which country will be the first to land

  • and establish a base.

  • China, the USA, Russia, and India

  • are all making strong efforts to get there.

  • But there are also private companies

  • including SpaceX and Blue Origin,

  • that have a lot more money to spend on going to the Moon.

  • But wait,

  • why exactly are these companies

  • doing this in the first place?

  • Apart from exploring the galaxy and breaking new ground,

  • there's another huge reason

  • these groups all want to be the first

  • to create a base on the Moon.

  • And that reason is money.

  • The Moon is chock-full of different resources.

  • It has gold, silver, and titanium in it.

  • The idea here is to mine these precious resources

  • and send them back to Earth.

  • Another resource the Moon has is helium-3.

  • It's incredibly rare here on Earth,

  • but not on the Moon.

  • That's because the Moon doesn't have an atmosphere,

  • and helium-3 comes from the Sun's radiation.

  • Over billions of years, the Moon has

  • been absorbing this chemical and

  • lucky for us, it can be used for energy.

  • Helium-3 is so powerful

  • that just 100 kilograms (220 lbs) of it,

  • could power the city of Dallas, Texas for an entire year.

  • Oh, and it's also worth a cool $40,000

  • for just 28 grams (1 ounce) of the stuff.

  • With these resources holding incredible value,

  • it's no secret these countries and companies

  • want to be the first to establish a base.

  • But even if they do, they won't really own it.

  • Back in 1967,

  • the United Nations decided that

  • no one can really own space.

  • This has the potential to cause huge tensions between various nations,

  • possibly leading to war.

  • But enough about all that drama.

  • You're on the Moon!

  • So, how exactly are you going to live here?

  • Assuming we get to the Moon in one piece,

  • which is already an incredibly difficult task on its own,

  • you'll then have to worry about establishing a base.

  • Experts suggest we live on the south pole,

  • as it gets the most consistent amount of sunlight.

  • There are also massive fields of ice that we'll be able to harvest.

  • Some other places on the Moon

  • don't get any sunlight for nearly a month at a time.

  • Luckily, you'll have robots to help you establish a base.

  • There are many different ways they'll be able to help.

  • One includes using Moon soil

  • to construct bricks

  • and configuring them in a dome-like fashion.

  • Sort of like a "moon-gloo."

  • This would make traveling to the Moon a lot cheaper

  • as we wouldn't have to bring everything from Earth to make our base.

  • But don't expect this base to be glamorous.

  • It'll most likely be several meters underground,

  • to protect you from the Sun's radiation.

  • And as for what you'll eat?

  • Well it'll be your standard dry astronaut food.

  • The good news is that

  • you should be able to grow some carrots and tomatoes.

  • A 2014 Dutch study found that

  • it's possible using soil on the Moon.

  • And what would you drink?

  • Unfortunately, quite a lot of it will be your recycled pee

  • as drinkable water won't be available on the Moon,

  • and it would be too heavy to ship there.

  • Another thing you'll need to seriously worry about is moondust.

  • This magnetic dust gets everywhere.

  • It'll get on your suit and even on your skin.

  • Previous astronauts have had allergic reactions to it.

  • It's also slightly sharp,

  • so accidentally swallowing any would be a huge problem.

  • But it's not just humans who need to worry about moondust.

  • It can get into machines as well,

  • causing them to overheat.

  • Before we settle on the Moon,

  • this is one massive problem we'll need to solve.

  • All these issues beg the question,

  • would you ever really want to be the first to settle on the Moon?

  • You'd most likely spend your time mining and just surviving,

  • with little time to run around in low gravity.

  • And besides,

  • we all know going here

  • is really just our first baby step to get to Mars.

  • So maybe you should just wait for that.

  • But that sounds like a story for another WHAT IF.

Imagine living on the Moon.
