Although there has never been a suicide bus bomb blast in the United States, experts agree it could happen in any American city, at anytime. A bus bomb attack is a gruesome scene, not only killing people on the bus but also injuring and killing people outside the bus as well; a terrifying scenario that authorities in the United States want to train for so that they can effectively save as many lives as possible. Join master of disaster Tim Samaras and his team of top scientists as they scientifically re-create the perfect terrorist crime scene, analyze their unique blast data and develop ground breaking emergency response plans that could one day, help save lives.

Tornado Alley observes scientist and inventor Tim Samaras as he attempts what has never been done before Tim has been asked by Boeing to catch monster hail and asked by the science community to study the interior and immediate exterior of the Tornado; not by observing from the side of the road or calculating speeds from distant radar signals, but from actually getting inside the storm itself. Master of Disaster - Tornado (working title) will join Tim as he chases through tornado alley looking for the perfect opportunity to deploy his top inventions, his sci-fi looking tornado probes to penetrate the interior and the mobil messonet team to document the atmosphere on the exterior of a tornado.

Disaster specialist Tim Samaras measures the immeasurable and examines a range of terrifying natural and man made disasters. Disaster specialist Tim Samaras measures the immeasurable and examines a range of terrifying natural and man made disasters including tornadoes and hail, collapsed buildings, avalanche and mountain rescues and terrorist bus bombings.

From the sand of Daytona Beach, to the dirt of Langhorne Speedway to the asphalt of Darlington Raceway, NASCAR has been a vibrant reflection of American society. In this episode, we meet Juan Pablo Montoya, an accomplished NASCAR racer in his pursuit of speed. We go behind the scene with the international icon of NASCAR.

Large enough to swallow 1000 Earths, Jupiter is a 90,000 mile wide ball of gas and liquid. Surrounded by 63 moons it is a solar system in miniature. But this is a system of extremes; volcanic plumes rise hundreds of miles into space, storms the size of the Earth rage for hundreds of years, and strange motions beneath icy surfaces hint at a possibility of life. The Galileo probe overcame many trials to become the first craft to orbit an outer planet. It made amazing discoveries that shifted the way we view how the solar system formed and found the first evidence of liquid water on the icy moon Europa. New missions are set to return to the gas giant to find out more. Join Naked Science as we delve beneath the cloud tops to reveal the mysteries on this Journey to Jupiter.

The latest installment of National Geographics popular franchise In the Womb follows the embryonic and fetal journey of one of natures most fascinating reproductive miracles identical twins. Witness the key moments during early embryogenesis from the spontaneous splitting of a single fertilized egg into identical twins through to the major milestones of twin fetal development, ending with their dramatic births. Along the way, learn how skin color is formed; what happens when aberrations in early development occur, producing conjoined twins; and how twins with ambiguous genitalia (hermaphrodites) can develop. Meet a pair of identicals who were separated at birth and met for the first time four decades later. Then, see dramatic 4-D ultrasound images of twins interacting in the womb in real time.

June 2010 marked the centenary of the birth of legendary underwater explorer Jacques Cousteau. This program juxtaposes historical footage from Cousteau’s earliest exploration of the Mediterranean Sea with that filmed by Enric Sala and Pierre-Yves Cousteau. It reveals the Mediterranean as it has never been seen before: stunning dive locations and magnificent sea life. The journey sets out to assess the health of the Mediterranean, an incredible journey back in time of a Sea that once served the ancient cities of Egypt, Greece and Rome.

Underwater explorers in the Baltic Sea set out to bring a recently discovered ghost ship - one of the most intact ancient wooden wrecks ever found - back to life. By pushing the frontiers of maritime archaeology and using the latest technology, the team hopes to recover artifacts from the ship, take measurements and create a 3-D model of the ship with pinpoint accuracy - unlocking a treasure trove of information.

During a dance contest in a new $50-million Hyatt hotel in Kansas City, overhead walkways collapse into the crowded lobby, killing 114 and injuring 186. What caused one of America's most devastating structural failures?

Eye of the Leopard tracks one cat for a remarkable three years in Botswana. She's called Legadema, or "Light from the Sky," and we follow her from the first vulnerable days as a cub all the way to developing into one of the most feared predators.

Get exclusive access to the construction of a man-made marvel suspended over one of Mother Nature's greatest wonders a horseshoe-shaped, glass-floored bridge that allows visitors to walk where eagles fly. NGC takes viewers behind the daring design and death-defying construction of the Grand Canyon Skywalk, formed from 1 million pounds of steel and glass, perched 4,000 feet above the Colorado River.

Supported by the National Geographic Society, the world's eminent blue whale scientists embark on a revolutionary mission: They'll find, identify, and tag California blue whales, use the DNA samples to confirm the xxx of individual whales, then rejoin the massive creatures' stunning migration when they collect at a chimera known as the Costa Rica Dome. These experts have observed, firsthand, courtship behavior among the whales at the moving mass of krill and currents 500 miles off the coast of Costa Rica. Now, they hope to find and record the Holy Grail of blue whale science -- the breeding and calving grounds of the biggest mammals in the sea.

Blending advanced CGI, archival footage, forensic science, dramatic eyewitness accounts and expert testimony, Seconds From Disaster deconstructs the chain of events leading to some of the world's most infamous disasters.

Join astronaut John Herrington for a behind-the-scenes look at NASA's final mission to repair the most famous telescope in the world, the Hubble Telescope. After the telescope suffered a massive malfunction in September 2008, NASA made multiple attempts to fix it without success. Now, on May 12, 2009, NASA will make one final attempt, and NGC has rare access to the preparations and the actual launch.
