On October 4, 1957, the Space Age dawned with the red hue of the Communist flag when the Soviet Union launched the first artificial satellite. Sputnik I stunned the world and spurred a surge in science education and innovation that changed our world forever. But was Sputnik I really a shock to America's leaders, and how close was the U.S. to getting into space first? NOVA draws on previously classified documents to tell the real story behind the opening chapter in the space race.

For 25 centuries the Parthenon has been shot at, set on fire, rocked by earthquakes, looted for its sculptures, almost destroyed by explosion, and disfigured by well-meaning renovations. It has gone from temple, to church, to mosque, to munitions dump. What could be next? How about a scientific search for the secrets of its incomparable beauty and astonishingly rapid construction? With unprecedented access, NOVA unravels the architectural and engineering mysteries of this celebrated ancient temp

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.

At a research site in Fongoli, Senegal, a female chimpanzee breaks off a branch, chews the end to make it sharp, and then uses this rudimentary spear to skewer a tasty bush baby hiding inside a hollow tree. It’s an astonishing breakthrough for primate researchers—the first time anyone has documented a chimpanzee wielding a carefully prepared, preplanned weapon. But it's only the latest in a slew of extraordinary new findings about ape behavior. The more researchers learn about the great apes—

A look at the 2002 discovery of a four-winged crow-sized dinosaur fossil dubbed Microraptor, which has rekindled the scientific debate over the origins of flight. Included is a wind tunnel test of a "flight-ready" model of the 130 million-year-old Microraptor.

The ancient Maya civilization of Central America left behind an intricate and mysterious hieroglyphic script, carved on monuments, painted on pottery, and drawn in handmade bark-paper books. For centuries, scholars considered it too complex ever to understand—until recently, when an ingenious series of breakthroughs finally cracked the code and unleashed a torrent of new insights into the Mayas' turbulent past. For the first time, NOVA presents the epic inside story of how the decoding was done—
