President's message on NASA

"On behalf of all Americans, I wish the crew of the Space Shuttle Discovery a safe and successful mission. Today's launch marks NASA's return to flight following the tragic loss of the Space Shuttle Columbia crew in February 2003. I thank the men and women of NASA who have dedicated themselves to putting our space program back on track. Our space program is a source of great national pride, and this flight is an essential step toward our goal of continuing to lead the world in space science, human space flight, and space exploration."
