We are already sending people to mars, but they can’t come back 🙁 so we know we can travel far, as far as the moon and mars.
We just need to make is a place where we can breathe and live. So a dome with controlled air and an ozone (because we need to be protected from the sun’s rays) would be the next step. once we have this, there would be nothing stopping us from having a holiday on the moon.
But did you know they are already selling tickets for a holiday OF the moon. If you have £100 million to spend (Yeh I do, just let me go to the bank HA), then you can fly to the moon, orbit the lunar surface and return safely to earth
Here is the link for this holiday, if you want to go 😛
Just ask you parents to pay
We’d need to be able to make the atmosphere breathable, which wouldn’t be too difficult really. Astronauts can already breathe in their shuttle in space, so a moon base would just be making this possible on a larger scale. The more difficult part would be making artificial gravity possible. At the moment we can’t create gravitational fields ourselves. Now, this isn’t a problem if you’re just bouncing around on holiday. But low gravity might make the swimming pool a bit interesting!
