Everybody knows the names of Neil Armstrong and Buzz Aldrin but America's journey into space is much bigger than that. It was the result of the blood, sweat and tears of thousands of men and women who worked behind the scenes in crucial ways - ordinary people who had 'the big idea'. Men and women who could watch the launch of rockets, the voyages of spaceships and the building of the international space station and know it wouldn't have happened without them. This is the story of the unsung heroes who took America into space. This episode looks at the engineers who, against all odds, built humanity's most powerful machine - the Saturn V rocket.
On August 21, 2017, millions of Americans witnessed the first total solar eclipse to cross the continental US in 99 years. As in all total solar eclipses, the moon blocked the sun and revealed its ethereal outer atmosphere - its corona - in a wondrous celestial spectacle. While hordes of citizens flocked to the eclipse's path of totality, scientists, too, staked out spots for a very different reason: to investigate the secrets of the sun's elusive atmosphere. During the eclipse's precious seconds of darkness, they gathered new clues on how our sun works, how it can produce deadly solar storms, and why its atmosphere is so hot.

The Asian tsunami of 2004 took thousands upon thousands of lives. It was a natural disaster of epic proportions. Like all tsunamis, it came with little warning. Most of us believe that a tsunami on this scale couldn't hit Europe - are we wrong? In 1607 Britain experienced one of its greatest natural disasters. An enormous flood engulfed Somerset and Monmouthshire, taking a huge number of lives and reducing thousands more to poverty. Traditionally scientists had regarded this forgotten tragedy as a freak storm surge. But in a 2003 Timewatch Professor Simon Haslett and Professor Ted Bryant challenged this view - gathering evidence to suggest that 1607 was in fact a British Tsunami. But the story doesn't end there: inspired by what they had discovered about 1607, Simon and Ted decided to delve deeper into the archives. They believe they have emerged with evidence for at least four more British Tsunami. Simon and Ted's work remains highly controversial. After the Tsunami of 2004 the British government commissioned a report which concluded that risk of tsunami in Britain is small. To weigh up the evidence, historical cartographer Vanessa Collingridge will be joining Simon and Ted on their journey. Vanessa's quest is to find out for herself whether she believes Simon and Ted are right - and to discover if the risk of Tsunami to Europe is bigger than most of us think. Timewatch will join Simon, Ted and Vanessa as they gather evidence for possible tsunami from 1014 to 1929. While she does this, with the help of Natural Hazard's expert Prof Bill McGuire, Vanessa will also explore how and why tsunami are created - and why they can be such an extraordinarily destructive force.
Stephen Fry tells the story of two young animals forced to grow up fast. A baby elephant shrew learns how speed is the secret to survival and a young mouse confronts the desert's deadliest creatures.
The illegal wildlife trade is a $20 billion dollar industry, exceeded only by the illegal trades in drugs, weapons, and people. The money stimulates violence, corruption and a sophisticated and dangerous international network of criminals. Two of the world's most iconic species are at the centre of this nightmare. With an average of 82 elephants and four rhino poached every day, there's now a real threat that these animals could become extinct in the wild. Hugh travels to Mozambique's worst affected area, Niassa National Reserve, to find out why they've lost almost two thirds of their elephants in only three years. He joins conservationists, rangers and villagers as he patrols from the air and on the ground to discover the grim reality of the situation.
