Latest Episode: D-Days's Sunken Secrets

May 28, 2014 Season 41 Episode 22 watch on (Paid)

From PBS - On June 6, 1944, the Allies launched the biggest armada in history to invade the Normandy beaches and liberate Europe from the Nazis. In less than 24 hours, more than 5,000 ships crossed the English Channel, along with thousands of tanks and landing craft and nearly 200,000 men. Hundreds of ships sank while running the gauntlet of mines and bunkers, creating one of the world’s largest underwater archeological sites. Now, NOVA has exclusive access to a unique collaboration between military historians, archeologists, and specialist divers to carry out the first complete survey of the seabed bordering the legendary beachheads. Dive teams, submersibles, and underwater robots will discover and identify key examples of the Allied craft that fell victim to German shellfire, mines, and torpedoes. D-Day’s Sunken Secrets unfolds a vivid blow-by-blow account of the tumultuous events of D-Day and reveals how the Allies’ intricate planning and advanced technology was vital to assure the success of the most ambitious and risky military operation ever launched.

Hunt for the Supertwister

Mar 30, 2004 Season 31 Episode 15

On May 3, 1999, one of the most powerful tornadoes ever recorded carved a path of complete destruction near Oklahoma City. To scientists, the supertwister held sobering lessons about the future for rapidly expanding cities in tornado-threatened areas. Most tornadoes form suddenly and with little warning. But now meteorologists are on the verge of a breakthrough that may solve the puzzle of how these killer storms spawn and where they are likely to strike. NOVA follows stormchasers as they probe the tornado's deadly secrets. The program features noted researchers Joshua Wurman of the Center for Severe Weather Research in Boulder, Colorado, and Howard Bluestein of the University of Oklahoma--fellow stormchasers who have perfected the art of tracking down tornadoes with instrument-laden vehicles designed to gather data from as close to the churning vortex as possible. Also included is Lou Wicker of the National Severe Storms Laboratory, who is creating computer models in collaboration with scientists at the National Center for Supercomputing Applications (NCSA)/University of Illinois, that provide exciting insights into the intricate sequence of steps that goes into spawning a twister. NOVA goes supertwister hunting with Wurman and Bluestein on a day that threatens tornadoes all across the Texas Panhandle. Wurman heads north and captures the first twin tornadoes ever recorded on radar. Meanwhile, Bluestein stays in the southern Panhandle and eventually bags his own treasure-trove of twister data. Not to be outdone, computer modeler Lou Wicker captures the biggest prize of all: a supertwister in the process of formation in the equations of his program. Having input data on an F4 storm that devastated Manchester, South Dakota, on June 24, 2003, he sees a supertwister take shape with uncanny similarity to the real thing.

MARS Dead or Alive

Jan 04, 2004 Season 31 Episode 9

In early January 2004, two spacecraft carrying identical robotic explorers touched down on the surface of Mars. On that day, NOVA presented a special television event that climaxed with live coverage as NASA/JPL scientists awaited the first critical signals confirming that the rovers had landed safely. The show features a gripping behind-the-scenes glimpse of the design, testing, and launch of the mission. The engineers face a tense deadline as Mars approaches its closest rendezvous with Earth; they're stretched to the limit as parachutes rip, bolts fail, and airbags pop; everything that can go wrong does. Watch them apply all their ingenuity to overcome the technical hitches. Then join NOVA's exploration of the latest clues in the ultimate quest for signs of life on the mysterious red planet.

Wright Brothers' Flying Machine

Nov 11, 2003 Season 31 Episode 6

Orville and Wilbur Wright were remarkable inventors, mechanics, risk-takers, and visionaries. They designed and built their own wings, steering devices, engines, and wind tunnel. But just how did they construct such an impressive flying machine? It takes a team of modern pilots, builders, aviation experts, and historians joined together to retrace, rebuild and re-fly planes built to the specifications developed by the Wright Brothers a century ago. Vivid footage captures both the Wrights’ own historic flights and the team’s attempt to fly an authentically recreated Wright “Model B.” As modern computer technology meets dusty artifacts, the Wrights’ aviation secrets emerge from the past and seem more impressive than ever. Discover how the Wright Brothers transformed themselves from bicycle mechanics to high-flying inventors who built a machine that changed the world during a mythical flight at Kitty Hawk on December 17, 1903, and see how they contrived to refine their incredible aircraft.
