First Man on the Moon (#4122H) Duration: 56:46 STEREO TVG

When Neil Armstrong set foot on the moon, he won instant fame. Yet this accomplished engineer and test pilot was so determined to stay out of the limelight that few know the personal story of how his rare combination of talent, luck and experience led to his successful command of Apollo 11. Nova presents an intimate portrait of an unassuming American hero through interviews with Armstrong's family and friends.

3D Spies of WWII (#3903) Duration: 56:46 STEREO TVPG (Secondary audio: none)

During World War II, Hitler's scientists developed terrifying new weapons of mass destruction. Alarmed by rumors about advanced rockets and missiles, Allied intelligence recruited a team of brilliant minds from British universities and Hollywood studios to a country house near London. Here, they secretly pored over millions of air photos shot at great risk over German territory by specially converted, high-flying Spitfires. Peering at the photos through 3D stereoscopes, the team spotted telltale clues that revealed hidden Nazi rocket bases. The photos led to devastating Allied bombing raids that were crucial setbacks to the German rocket program and helped ensure the success of the D-Day landings. With 3D graphics that recreate exactly what the photo spies saw, NOVA tells the suspenseful, previously untold story of air photo intelligence that played a vital role in defeating Hitler.

Building The Great Cathedrals (#3711H) Duration: 54:46 STEREO TVG (Secondary audio: DVI)

Carved from 100 million pounds of stone, soaring effortlessly atop a spiderweb of masonry, Gothic cathedrals are marvels of human achievement and artistry. But how did medieval builders reach such spectacular heights? Consuming the labor of entire towns, sometimes taking 100 years to build, these architectural marvels were crafted from just hand tools and stone. Many now teeter on the brink of catastrophic collapse. To save them, an international team of engineers, architects, art historians and computer scientists searches the naves, bays, and bell towers for clues to how the dream of these heavenly temples on earth came true. Nova's teams perform hands-on experiments to investigate and reveal the architectural secrets that the cathedral builders used to erect their soaring, glass-filled walls. This program reveals the hidden formulas, drawn from the pages of the Bible itself, that drove medieval builders ever upward.

Great Cathedral Mystery (#4105H) Duration: 56:46 STEREO TVG

The Duomo in Florence is a towering masterpiece of Renaissance ingenuity and an enduring source of mystery. A team of US master bricklayers help build a unique experimental "mini-Duomo" using period tools and techniques. Will it stay intact during the final precarious stages of closing over the top of the dome?

Rise of the Drones (#4003H) Duration: 56:46 STEREO TVPG

A revolution is transforming the armed forces of every nation. Nova launches an investigation of the explosive growth of airborne UAVs or pilotless drones. During the invasion of Iraq in 2003, the US deployed only a handful; now, it has more than 7000. Besides the US, over 40 other nations are now building or buying these increasingly lethal and cost-effective weapons, and it's only a matter of time before a terrorist group turns the technology against Western targets. The latest Predators can track 12 targets at once, trace footprints back to their source and even recognize individual faces. Yesterday's soldiers and pilots put their lives on the line but today, a UAV pilot can "fly" a mission in Afghanistan remotely from a base in Nevada. As one pilot said, after carrying out a strike, "within 20 minutes you can be sitting at the dinner table talking to your kids." That new ability has already saved hundreds if not thousands of US service lives but may make military strikes a more tempting, seemingly risk-free option.

Iceman Murder Mystery (#3815H) Duration: 56:16 STEREO TVPG-V (Secondary audio: DVI)

He's been dead for more than 5,000 years. He's been poked, prodded and probed by scientists for the last 20. And yet today, Otzi the Iceman, the famous mummified corpse pulled from a glacier in the Italian Alps nearly two decades ago, continues to keep many secrets. Now, through an autopsy like no other, scientists attempt to unravel more mysteries from this ancient mummy than ever before, revealing not only the details of Otzi's death, but an entire way of life. How did people live during Otzi's time, the Copper Age? What did we eat? What diseases did we cope with? The answers abound miraculously in this one man's mummified remains.

Big Bang Machine (#4201H) Duration: 56:46 STEREO TVG

On July 4, 2012, scientists at the giant atom smashing facility at CERN announced the discovery of a subatomic particle that seems like a tantalizingly close match to the elusive Higgs Boson, thought to be responsible for giving all the stuff in the universe its mass. Since it was first proposed nearly fifty years ago, the Higgs has been the holy grail of particle physicists: if they can find it, it will validate the "standard model" that underlies all of modern physics. CERN's scientists are still scrutinizing the results from July to see how well they fit the Higgs prediction. If the data conceals surprises, they could upend much of what we thought we knew about the particles and forces that make up our universe.

Sunken Ship Rescue (#4202H) Duration: 56:46 STEREO TVPG

Nova follows the epic operation to secure, raise and salvage the Costa Concordia cruise ship, which ran aground and tragically capsized off the coast of Italy on January 13th 2012, killing 32 passengers. Moving the ship - which stretches the length of three football fields, weighs over 114,000 tons and lies half submerged on the site of a protected reef with a 50-meter long hole in its hull - from its precarious perch on the edge of a 60 meter high underwater cliff will be a huge technical and logistical challenge. Now, Nova joins a team of more than 500 divers and engineers working around the clock as they attempt the biggest ship recovery project in history.

Sinkholes - Buried Alive (#4203H) Duration: 56:46 STEREO TVPG

In Tampa, Florida, in February 2013, a giant hole in the ground opened up and swallowed half a house, killing 36 year-old Jeffrey Bush as he slept in his bedroom. A month later, a golfer in Illinois survived an 18-foot fall when the 14th hole caved in beneath his feet. Both were victims of sinkholes-a notorious worldwide hazard that lurks wherever limestone bedrock is found. When carbon dioxide dissolves in rainwater, it forms a weak acid that attacks the soft limestone, riddling it like Swiss cheese with hidden underground rivers, caves and hollows. While this process of erosion takes millions of years, the fragile roof of a cavern near the surface can collapse in an eye blink, with little or no advance warning. Sinkholes can range from a few meters across to one in Egypt that measures 50 x 75 miles, and a Chinese hole nearly half a mile deep. Filled with compelling eyewitness video of collapsing sinkholes and authoritative science from expert geologists, Nova investigates what it's like to have your world vanish beneath your feet.
