While speaking at Rice University in Houston, Texas, on September 12, 1962, John F. Kennedy stated:
"We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."
His entire speech is found on: "John F. Kennedy Moon Speech - Rice Stadium". And the YouTube video, as seen above, "We Choose to go to the Moon" also provides the speech (http://www.youtube.com/watch?v=g25G1M4EXrQ).
The NASA article "NASA Highlights 50th Anniversary of Kennedy 'Moon Speech' and Looks Ahead" states that NASA Television will televise on September 12, 2012, the entire Moon Speech by Kennedy.
In addition, "NASA's website will have a special blog from NASA Administrator Charlie Bolden and an online feature that highlights the speech and provides information about NASA's current and future exploration programs."
And, "NASA.gov and NASA TV will show a message about the speech from NASA astronaut Suni Williams on board the International Space Station. Williams will become commander of the orbiting laboratory this weekend."
