Earth is the cradle of humanity, but one cannot live in a cradle forever.

Man must at all costs overcome the Earth's gravity and have, in reserve, the space at least of the Solar System.

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?

Mankind will not forever remain on Earth but, in the pursuit of light and space, will first timidly emerge from the bounds of the atmosphere and then advance until he has conquered the whole of circumsolar space.

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

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!
