The moon is the closest celestial body to Earth.

様態の副詞

Humans have been gazing up at it for our entire existence, finally landing on its surface

We’ve walked on the moon, carried out science experiments on the moon, we’ve even driven

a car, hit golf balls and briefly grew cotton on the moon.

So, the obvious next question is, when are we going to start living on the moon?

For decades pop culture has been teasing us with lunar colonies, military bases, space

hotels and more, but in order to populate the moon, or other planets, we may need to

Now, let’s first clear up what we mean when we say “lunar base.”

We’re not talking about a bustling, domed metropolis.

We’re talking about, an outpost, a lab, a lunar habitat where scientists, or possibly

rich tourists, can live and work for an extended period of time, maybe something similar to

the 6 month average stay of an astronaut on the ISS.

For the first time in human history we are going to

the Moon not to go and come back, but we are trying to go to the Moon and stay there, hence

we need to have a Moon base, like a base where we could live through science, through operations

Only twelve people have ever set foot on the moon, the last being Eugene Cernan and Jack

Schmitt during Apollo 17 way back in 1972.

Since then we’ve accomplished many amazing things in space, from landing a rover on Mars

But we haven’t sent anyone back to the moon...yet.

I think what we're going to see is a big ramping up of interest in lunar exploration, both

in orbit and at the surface, internationally, from national agencies and governments, but

also from the private sector and from commercial entities.

This interest is going to be driven by science, by engineering, by technology development,

by preparing for future exploration, by understanding the resources that we find locally at the

Moon, and how we can use those things to prepare us for what we do later…

You see, setting up a base on the moon may be key to, not only understanding our past,

We can study the impact craters and geology to help us better understand the formation

We can set up radio telescopes on the far side which would be shielded from Earth’s

electromagnetic interference, which would enable us to better study the big bang.

And we can use a moon base as a testing ground for an eventual space colony.

Because, right now, we have no data on the health of astronauts living on another astronomical

And maybe most importantly, we can discover how efficiently we can be on another world,

since we won’t be able to ship all of our supplies.

So if we as a species want to go beyond, if we want to live in space, if we want to work

elsewhere in the solar system, then the way we do that is we go to the Moon, and we learn

to live and work for prolonged periods of time away from the Earth

One possible important resource might be newly confirmed lunar ice, which scientists think

We could extract the ice, isolate the oxygen and hydrogen, and manufacture fuel on the

moon, meaning lunar visitors wouldn’t be bogged down with the extra weight of return

Another resource is the regolith, which some space agencies think may be the key to building

Well, if you wanted to build a moon base, the sort of obvious thing is you'd want to

use lunar regolith as your basic building material, because there's lots of it.

If you have to import your construction materials from Earth, it's just a ridiculously expensive

So you need to develop the capacity to turn regolith into something useful, and there's

What we should do is something completely different, that is we have to ship to the

moon a 3D printer and the 3D printer, using the dust that is already on the Moon, so the

Moon regolith, would build completely automatically using the sunlight endlessly available on

the Moon surface, by baking layer after layer the Moon base

Others think we could start shipping modules to the moon piece by piece, similar to how

we’ve built space stations in low earth orbit.

Or we could just dig an underground bunker, tunneling under the regolith.

But whichever plan we go with, there needs to be thick walls between the people inside

The Moon can be very hot during the daytime and very cold at night, so you need to be

able to moderate those temperatures so that astronauts can live in a comfortable environment.

You're also exposed to radiation that comes from the Sun and from deep space, and so you

need to find ways of reducing the radiation that astronauts are exposed to.

A base on the moon would look basically like a very large hill from the outside.

And the reason for that is there's quite a bit of radiation on the surface of the moon...For

your radiation shielding you need about five or six meters, about 15 to 20 feet.

And you've got to pile that on top of your modules, which are probably a good 10 feet.

So you've got basically a hill 30 or 40 feet tall.

The inside, particularly for early bases, is probably very much like the inside of the

Lots of wires and laptops and metal and storage units and stuff like that….

But of course this very large hill will need to be top of the line, equipped and set up

with everything needed to maintain a lunar crew.

The major thing you're going to need is, of course, to be able to get there, to get back,

to be able to enable astronauts to survive, to be able to work in a comfortable environment

that is safe, but then also to have the facilities that are needed for research and for transport

In particular, power is going to be a major aspect of any infrastructure.

Well, the stuff you need before you build a moon base is very similar to what you need

The first, most important thing is you have to be able to breathe.

So that means you need a pressure vessel, and it means you need an atmosphere that has

enough oxygen and enough other stuff so the oxygen doesn't turn into an inferno.

Of course, the food needs a lot of water, because you need water to grow crops

You're going to have to have massive resupply from Earth or you're going to have to figure

out how to get water out of the lunar soil.

Yes, a lunar base does seem futuristic and sci-fi, but we’re already working on all

We’re 3D printing building blocks using materials that simulate lunar regolith.
