Inside The Megastorm (Episode #3916#)

KQED 9: Wed, Nov 21, 2012 -- 9:00 PM

Was Hurricane Sandy a freak combination of weather systems? Or are hurricanes increasing in intensity due to a warming climate? How did this perfect storm make search and rescue so dangerous? This episode takes viewers moment by moment through Hurricane Sandy, its impacts, and the future of storm protection. Through first person accounts from those who survived, and from experts and scientists, it gives scientific context to a new breed of storms.

Space Shuttle Disaster (Episode #3512H)

KQED Plus: Wed, Nov 21, 2012 -- 5:00 AM

Space Shuttle Columbia disintegrated over Texas just 16 minutes before it was due to land. All seven astronauts aboard perished, and the worldwide repercussions on the future of the space shuttle program were enormous. Through interviews with astronauts and their families as well as with members of the Columbia Accident Investigation Board, the program gives viewers a new look at the Columbia tragedy and at NASA itself.

Lizard Kings (Episode #3616)

KQED Plus: Wed, Nov 21, 2012 -- 4:00 AM

They look like dragons. Armed with sharp teeth, tearing claws and a whip-like tail, these fearsome creatures are not only powerful, they're also smart. Top predators with intelligence, who learn as they hunt, and who use their brain to track down prey, no matter what. Sounds like these cunning hunters should be a big-brained mammal, but these creatures are reptiles, members of a family that evolved when the dinosaurs roamed the earth. They are the largest lizards still walking the planet, the monitor lizards -- the Lizard Kings.

What Darwin Never Knew (Episode #3617)

KQED Plus: Wed, Nov 21, 2012 -- 2:00 AM

Earth teems with a staggering variety of animals, including 9000 kinds of birds, 28,000 types of fish and more than 350,000 species of beetles alone. What explains this explosion of living creatures - 1.4 million different species discovered so far, with perhaps another 50 million more to go? The source of life's endless forms was a profound mystery until Charles Darwin's revolutionary idea of natural selection, which he showed could help explain the gradual development of life on earth. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? And how did we evolve?

Ultimate Mars Challenge (Episode #3915H)

KQED 9: Wed, Nov 14, 2012 -- 9:00 PM

It could be NASA's last chance to set wheels down on Mars until the end of the decade: in August 2012, a rover named Curiosity touched down inside Mars' Gale Crater, carrying 10 new instruments that advanced the quest for signs that Mars might have once been suitable for life. But Curiosity's mission is risky. After parachuting through the Martian atmosphere at twice the speed of sound, Curiosity is gently lowered to the planet's surface by a "sky crane." This first-of-its-kind system has been tested on Earth, but will it work on Mars?
With inside access to the massive team of scientists and engineers responsible for Curiosity's on-the-ground experiments, Nova is there for the exhilarating moments after Curiosity's landing - and for the spectacular discoveries to come. But no rover does it alone: Curiosity is joining a team that includes the Mars Odyssey, Express and Reconnaissance orbiters, along with the tireless Opportunity rover. As we reveal the dynamic new picture of Mars that these explorers are painting, we discover the questions raised by 40 years of roving Mars: How do we define life? How does life begin and what does it need to survive? Are we alone in the universe?

Mystery of Easter Island (Episode #3914H)

KQED 9: Wed, Nov 7, 2012 -- 9:00 PM

A remote, bleak speck of rock in the middle of the Pacific, Easter Island, or Rapa Nui, has mystified the world ever since the first Europeans arrived in 1722. How and why did the ancient islanders build and move nearly 900 giant statues or moai, weighing up to 86 tons? And how did they transform a presumed paradise into a treeless wasteland, bringing ruin upon their island and themselves? Nova explores controversial recent claims that challenge decades of previous thinking about the islanders, who have been accused of everything from ecocide to cannibalism. Among the radical new theories is that the islanders used ropes to "walk" the statues upright, like moving a fridge. With the help of an accurate 15-ton replica statue, a Nova team sets out to test this high-risk, seemingly unlikely theory.

Ghosts of Machu Picchu (Episode #3704H)

KQED 9: Thu, Nov 1, 2012 -- 3:00 AM

Perched atop a mountain crest, mysteriously abandoned 400 years ago, Machu Picchu is the most famous archeological ruin in the Western hemisphere and an iconic symbol of the power and engineering prowess of the Inca. In the years since Machu Picchu was discovered by Hiram Bingham in 1911, there have been countless theories about this "Lost City of the Incas," yet it remains an enigma. Why did the Incas build it on such an inaccessible site, clinging to the steep face of a mountain? Who lived among its stone buildings, farmed its emerald green terraces and drank from its sophisticated aqueduct system? NOVA joins a new generation of archeologists as they probe areas of Machu Picchu that haven't been touched since the time of the Incas and unearth burial grounds of the people who built the sacred site.
