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.

Some 220 miles above Earth lies the International Space Station, a one-of-a-kind outer space laboratory that 16 nations came together to build. Get a behind-the-scenes look at the making of this extraordinary structure in this spectacular IMAX film. Viewers will blast off from Florida's Kennedy Space Center and the Baikonur Cosmodrome in Russia for this incredible journey -- IMAX's first-ever space film. Tom Cruise narrates.

Blast off on a journey of a lifetime as this high-flying documentary takes you aboard the space shuttle Discovery with Comm. Pam Melroy and crew and into orbit for a rendezvous with the International Space Station. Traveling to more than 220 miles above the Earth's surface, the seven-member Discovery team carries out its 2007 mission and stills find time for some zero-gravity fun before returning to Earth at a top speed of mach 25.
