With every century
Our eyes on the universe have been opened anew
We are witness
To the very brink of time and space

[Robert Jastrow]
We must ask ourselves
We who are so proud of our accomplishments
What is our place in the cosmic perspective of life?

[Carl Sagan]
The exploration of the cosmos
Is a voyage of self discovery
As long as there have been humans
We have searched for our place in the cosmos

[Richard Dawkins]
Are there things about the universe
That will be forever beyond our grasp?
Are there things about the universe that are
Ungraspable?

[Sagan]
One of the great revelations of space exploration
Is the image of the earth, finite and lonely
Bearing the entire human species
Through the oceans of space and time
