  • Hey there. Welcome to Life Noggin.

  • The moon is our closest celestial neighbor. It's fairly small, has a similar makeup

  • to Earth, and there's water! It might sound like an ideal place to set up camp, but it's

  • really not. So, why can't we live on the moon?

  • In the last decade, there's been a lot of hype about humans going back to the moon.

  • Japan's space agency, JAXA, was planning to have a fully functioning moon-base in place

  • by 2020 but that plan fell through. NASA declared they'd have one built and fully staffed

  • by 2024 but their plans shifted to an orbiting lunar station, rather than a surface one.

  • Clearly, there's a reason these ideas keep getting nixed.

  • Let's start with some lunar basics. Days and nights are a lot different on the moon.

  • Daytime and nighttime last about 14 Earth days each. It can reach 250ºF during the

  • day and drop to -380ºF at night. In order to survive in this kind of environment, everything

  • from space-homes to space-cars to space-suits would need to be built to function in varying

  • extreme temperatures. And that's just the start of it.

  • The moon has basically no atmosphere protecting it from the constant barrage of harmful UV

  • rays from the sun. These solar rays can do some serious damage to our fragile human bodies,

  • especially during solar storms when the moon's surface can be hit with hundreds of rems of

  • radiation. If you're struck by radiation levels like that without protection or treatment,

  • there's a 50% chance you'll die.

  • Gravity is another problem. The moon's gravity is one-sixth that of Earth's. Levels that

  • low drastically weaken your muscles and bones and even changes how your heart and nervous

  • system function.

  • The moon's environment isn't ideal for building either, which we'd obviously need

  • to do a lot of if we're wanting to live up there. We'd need things like homes, power

  • generators, schools and hospitals. The moon's surface is covered in a layer of something

  • called lunar regolith. This regolith is basically a mixture of ground up stone, minerals and

  • glass. Across the surface, depths vary from about 15 to 30 feet and it's really hard

  • to dig through. Astronauts even had problems with regolith during the short Apollo missions,

  • when it built up in their spacesuits and equipment stiffening joints, freezing switches and disrupting

  • hydraulics.

  • People have argued that since regolith is partly made of oxygen, we could mine that

  • oxygen to create water, breathable air and rocket fuel but in order to do that, the regolith

  • would need to be heated to over 1,500ºF. And getting machines to the moon that could

  • heat up that regolith, as well as ones to construct buildings and generate energy, would

  • be tricky to say the least.

  • NASA's upcoming rocket, the Space Launch System, will be the agency's biggest rocket

  • to date but will still only have enough room for 4 astronautsNo extra room for things

  • like water processing machines or building materials that we'd need to live on the

  • moon. We'd need a much bigger rocket.

  • But put all these formalities aside and think about the cost of colonizing the moon! It's

  • estimated that a small base for 10 people would cost about $10 billion. That's half

  • of NASA's annual budget! Then add in the costs of upkeep, food and supply delivery,

  • power generation, infrastructure creation, all those kinds of things. That would add

  • up pretty quickly!

  • Unless we can figure out how to bypass all these issues, we definitely shouldn't be

  • living on the moon.

  • Would you try living on the moon? Let us know in the comments.

  • On the topic of space, my friend Natalie is a professional gemologist. She's making awesome

  • videos about gems, fossils, crystals, meteorites, and all kinds of gemstone related stuff. Natalie

  • makes two great videos a week and I highly recommend you subscribe. She just made a video

  • about if it rains diamonds on Saturn. Check it out.

  • As always, my name is Blocko. This has been Life Noggin. Don't forget to keep on thinking.

Hey there. Welcome to Life Noggin.
