With more than 27 years of service, the space shuttle Discovery has clocked more time in space than any other shuttle. She has flown more than 148 million miles, and has become one of the most storied spacecraft in American history. Join us as we celebrate her remarkable past and follow her final flight: to the Smithsonian National Air and Space Museum. It's an emotionally charged mission full of logistical challenges. Discovery is a robust, but very fragile aircraft, and getting her to D.C. in one piece will require some innovative engineering.

In unusual circumstances, scientists from different countries work together to achieve a common scientific goal. Locked in their spinning space lab, they are isolated from the world — family and friends - and can only watch from the outside as life on Earth continues without them. The space station is a monument not only to the weaknesses of humanity, but also to its ability to do the impossible for the sake of life in space.
