JOHN HOLDREN: If anybody has been harboring doubts about the status of U.S. leadership in space, well, there's a one ton automobile-size piece of American ingenuity...

(SOUNDBITE OF CHEERING AND APPALUSE)

Late Sunday night Pacific Time, they'll learn if nearly a decade of hard work will result in a priceless scientific laboratory landing safely on Mars or if the rover known as Curiosity will turn into a useless pile of junk. Everything depends on what happens during the seven minutes of terror, the time it takes the probe to go from the top of the Martian atmosphere to the planet's surface.
