Exploration really is the essence of the human spirit, and to pause, to falter, to turn our back on the quest for knowledge, is to perish.

Exploration is really the essence of the human spirit.

War and space exploration are alternative uses of the assertive, exploratory energies that are so characteristic of human beings. They may also be mutually exclusive because if one occurs on a massive scale, the other probably will not.

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?

Like most scientists, we felt that in the past human space exploration had been driven by politics and the science had been extremely thin.

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!
