America's experiences during the Civil Rights Movement and the Space Race are well documented. However, few know about the moment these two worlds collided, when the White House and NASA scrambled to put the first black astronaut into orbit. This is the untold story of the decades-long battle between the U.S. and the Soviet Union to be the first superpower to bring diversity to the skies, told by the black astronauts and their families, who were part of this little known chapter of the Cold War.

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.
