Ok, so NASA needs to buy a construction company. Then, we get a space rocket, fill it with construction materials. Fill it with guys who work in construction. Then they build as much of a warehouse as they can before their oxygen tanks run out. Then they come back to earth. Replace the oxygen tanks, and send another rocket with more construction materials, and keep building that warehouse.
Then keep doing that until they're done building the warehouse. Now, the next trip there they can ship them with tons of oxygen tanks instead of construction materials.
So now they can stay up there longer than a few days. Now they can ship another rocket with construction materials, and food, and supplies.
And when it gets there, now we have a warehouse to store all of it. And now they can start building houses. And they can bring plants to create oxygen. Bring some trees to plant.
Now you have roads, and houses, and empty communities. So if you don't like earth, you can leave.
...........I just need to figure out a way to create water on the moon.
Yeah, but just think of the sports rivalries. Once you set up the MoonMen in MLB, you'd win the World series every year! Because all the other teams can't tolerate the 9 day travel between the moon and earth.
So all your games would be home games, and your opponents would be exausted the first day of a 3 day series.
Imagine winning 30% of your games by playing your worst pitcher.
And then you just need to win 1 game to win the 3 game set.
So realistically, winning an average of 70% of your games would be fairly simple. Then if you can get a really GOOD team, you might get 80-100% of your games. But on average, even with a meh team, you'd still roughly win 60% of your games.
