Now, of course, the great thing about the solar system as a frontier is that there are no Indians, so you can have all the glory of the myth of the American westward expansion without any of the guilt.

All of this got me thinking about the history of the westward expansion, and got me to wondering how the exploration of the Solar System would be changed if there were an indigenous presence out there.

Then, I realized that there is an indigenous presence in the Solar System. It's us. So, then, I got to wondering what would happen if a more technologically advanced society moved next door to us, the way we moved next door to the American Indians.

We're going to understand that there is life on other bodies in the solar system.

When you look at the stars and the galaxy, you feel that you are not just from any particular piece of land, but from the solar system.

Our solar system is actually a wild frontier, teeming with different, diverse places: planets and moons, millions of objects of ice and rock.
