In space travel there is a saying that the first 50 miles and the last 50 miles are the most dangerous. Explore the controlled explosion of launch, the fiery crucible of re-entry and everything in between. See how a single spark inside a spacecraft or a micrometeoroid less than an inch wide hitting a space station can turn a routine mission into a lethal nightmare. As the missions become longer, venturing to Mars and beyond, the potential disasters will only become bigger. What would happen if a spacecraft ventured too close to a black hole or was hit by a gamma ray burst?
Most planets we know of are so hellish, it seems impossible that anything could live. But it's amazing where life can take hold in the Earth. Astrobiologists look for simple single-celled microbes known as extremophiles in places as Danakil Depression, known in Ethiopia as 'The Gateway to Hell.' In Episode 2, the fictional world is Janus, a planet in such a close orbit than its rotation is locked by the star's gravity and it always shows the same face to its sun. On one side of the planet, it's always daytime, a searing desert. On the other side, it's forever night, a frozen shadowland. Squeezed between the two, a sliver of perpetual twilight. Freezing meltwater flows from the cold side, carving canyons through the landscape. Deep in these canyons lives an extraordinary five-legged creature.
Travel writer Simon Reeve embarks upon two long-distance journeys across Turkey, exploring this dramatic and beautiful country that now finds itself at the centre of world events. In this programme, he visits Istanbul and the beaches and crystal clear waters of the Aegean Sea, before ending up at the war-torn border with Syria. In the region thought to have been the origin of the first vineyards, Simon meets a producer now trying to sell wine in a Muslim country with an increasingly conservative government.

Along Turkey's famous Turquoise Coast, Simon has a taste of luxury at the country's most expensive hotel, but discovers an industry on its knees as war in Syria and deadly terror attacks keep millions of holidaymakers away.
