November 2, 2010 - The most famous clock in the world counts down the time until lift-off of the Space Shuttle Discovery's final mission due to the retirement of the Space Shuttle program (bathed in light in the background).

Due to a structural problem in the main fuel tank, Discovery's launch was delayed pending resolution of the problem.
