Latest Episode: Killer Landslides

Nov 19, 2014 Season 42 Episode 9 watch on (Paid)

Just before 11 a.m. on March 22, 2014, an ominous rumble startled the residents of the community of Oso, Washington. It was the terrifying sound of what would become the United States' deadliest landslide in decades. The equivalent of one million dump truck loads of earth came plummeting down the valley. In a little over two minutes, a pile of debris up to 75 feet deep slammed into the neighborhood of close to 50 homes. While a massive search and rescue effort continues at the site, geologists are tracing the geological history of Oso to explain why the site was so unstable. But all around the world, scientists have reason to fear that the worst is yet to come. Globally, landslides and other ground failures take a tremendous human and economic toll, and with climate change bringing a sharp rise in precipitation, the threat of bigger, more frequent landslides is growing. As NOVA surveys landslide danger zones, discover how and why landslides happen, and how radar monitoring technologies could help issue life-saving warnings.

The Great Robot Race

Mar 29, 2006 Season 33 Episode 17

Twenty-three bizarre looking vehicles line up at the starting gate of the DARPA Grand Challenge with one thing in common: there’s nobody behind the wheel. Sponsored by the Pentagon’s research agency, this race for robotic, driverless vehicles has a $2 million prize. Its ultimate goal is to gather new ideas for the future of unmanned warfare. With names like Terramax, Highlander, Ghostrider, and Stanley, these vehicles are armed with cutting-edge technology, including artificial intelligence, laser-guided vision, GPS navigation, and 3-D mapping systems. But can some of the world's most advanced robots overcome a grueling, 130-mile stretch of Nevada's scorching desert terrain? NOVA follows the competing engineering teams as they deal with the glitches, system crashes, and tight deadlines that threaten to derail them at every turn. NOVA's cameras capture the race's technical challenges, hilarious pitfalls, and a final twist as a surprise contender comes up from behind to steal the race.
