A deity among the Greeks and Romans. He was the god of light and day (the "sun god"), of archery, prophecy, medicine, poetry, and music, etc., and was represented as the model of manly grace and beauty; -- called also Phebus.
The important achievement of Apollo was demonstrating that humanity is not forever chained to this planet and our visions go rather further than that and our opportunities are unlimited. Neil Armstrong
Cultures have long heard wisdom in non-human voices: Apollo, god of music, medicine and knowledge, came to Delphi in the form of a dolphin. But dolphins, which fill the oceans with blipping and chirping, and whales, which mew and caw in ultramarine jazz - a true rhapsody in blue - are hunted to the edge of silence. Jay Griffiths
We collectively have a special place in our heart for the manned space flight program - Apollo nostalgia is one element, but that is only part of it. American culture worships explorers - look at the fame of Lewis and Clark, for example. The American people want to think of themselves as supporting exploration. Nathan Myhrvold
