Millions remember the countdowns, launchings, splashdowns, and parades as the U.S. raced the USSR to the moon in the 1960s. But few know that both countries also ran parallel space programs, whose covert goal was to launch military astronauts on spying missions. With investigative journalist James Bamford, NOVA delves into the untold story of this top-secret space race, which might easily have turned into a shooting war in orbit.

In this program, an eye-opening documentary on the National Security Agency by best-selling author James Bamford and Emmy Award-winning producer Scott Willis, NOVA exposes the ultra-secret intelligence agency's role in the failure to stop the 9/11 attacks and the subsequent eavesdropping program that listens in without warrant on millions of American citizens.

NOVA examines the science and technology behind cyber warfare and asks if we are already in the midst of a deadly new arms race.
