One of the big things about space exploration is that it is as expensive as it is complicated, and you need all the countries of the world to help if you want to accomplish big goals.

Part of what drives us to explore and discover is the intangible: expanding our horizons, feeding our curiosity, finding all those unexpected things, and trying to answer those profound questions discussed in previous chapters, like how did the universe begin? How did life begin? Are we alone?

If you want a nation to have space exploration ambitions, you've got to send humans.

Decreasing the budget on the space exploration is nothing but a great treason to humanity! Space exploration is closely related to our very existence! Cut the budget on other things and increase the budget on the space exploration! Think great; if you do not think great, universe annihilates you!

Sailors on a becalmed sea, we sense the stirring of a breeze.

Across the sea of space, the stars are other suns.
