After the tragic loss of the space shuttle Challenger on January 28th, 1986, President Reagan addressed the nation from the Oval Office. He spoke of the courage of the astronauts that we lost and his words helped to give strength to millions of broken hearts.

"For the families of the seven, we cannot bear, as you do, the full impact of this tragedy. But we feel the loss, and we're thinking about you so very much. Your loved ones were daring and brave, and they had that special grace, that special spirit that says, "Give me a challenge and I'll meet it with joy." They had a hunger to explore the universe and discover its truths. They wished to serve, and they did. They served all of us."
