We could probably build a self-contained area on
the moon and live in it temporarily, but the cost
would be enormous. You can estimate it if you
find out how much it costs to send a kilogram of
something to the moon.
How many people
would be living there? How big would the space
need to be? How much would the building weigh?
Now you have to transport that to the moon, plus
all the tools and materials, workers, and the
space vehicle itself. Remember that the workers
have to live in the ship while the moon base is
being constructed. Construction would be very
slow because workers would be in clumsy suits.
Robots might be used for some of the work. We
would have to transport them too. How long would
the people be living on the moon? Every day a
person uses 500 l (125 gal) of water here on
earth. (That doesn't count the 7200 l used per
person per day for farming, manufacturing, etc.)
How much would the water supply weigh? Now for
the oxygen. How much of that do you need per day?
Then there's food, fuel, batteries, medical
supplies, etc. You can probably think of lots of
other things that you will need.
couldn't stay on the moon for too long. When our
bodies are weightless, they start breaking down.
One problem is that our muscles atrophy (get
The bottom line is that it would
be an adventure to visit there, but you couldn't
stay there long. The people on Earth would have
to work extremely hard to get you and your stuff
there. It's another good reason to take good care
of the Earth.
