“ The success of America's Space Shuttle, the most sophisticated space research vehicle yet developed, reaffirms the spirit of confidence, courage, pride, ingenuity, and determination which has characterized the history of America's space program. As the Shuttle continues to demonstrate and expand its capabilities, and as we progress towards a permanently manned space station, the spirit of July 20, 1969, burns brilliantly, leading our journey into the future.
Space exploration is part of the human adventure. Through it, we challenge ourselves to strive and to achieve. ”

“ It is said there are two fundamental differences between human beings and other species: we have souls and we have curiosity. The exploration of space is a testament to each of these differences. It is our curiosity which drives our explorations, and it is our soul which gives these explorations meaning. ”

“ The information obtained adds greatly to the accumulated wisdom of mankind necessary for an understanding of the fundamental processes and origins of life, providing insight into perplexing mysteries of the universe. Because space has no boundaries, the information and benefits from space exploration accrue to mankind's advantage in many different spheres. ”
