Episode 2
Dara loves telescopes and is also a keen astrophotographer. In his back garden, Dara shows some of the pictures he has taken of the moon, but they all show the same side. Why is this? And what secrets does far side of the moon hold?
Dara visits Jodrell Bank – home of the UK's largest radio telescope - to tell the story of how the first photograph of the far side of the moon was taken in the 1950s and why the picture left scientists baffled, because it showed that the far side looks completely different to the side we see every evening.
But there are other secrets that we are only just now starting to unlock. Scientists have been testing the rocks that the last astronauts who walked on the moon brought back, and have recently discovered that locked within them is water. Lots of it. Dara finds out how this discovery is changing lunar exploration.
But everyone knows that to discover further secrets that moon might hold; we need to go back there. Dara travels to Cologne in Germany to meet Samantha Cristoforetti, a European astronaut who hopes to one day walk there. And Dara tries a virtual reality headset used to train astronauts as he takes his very own ‘giant leap', walking on the moon's surface.
Back in the UK Dara visits British scientists building technology they hope will solve the moon's final secrets. Dr Simeon Barber shows Dara some of the miniaturised technology being sent to the moon over the next decade to study it and Professor Mahesh Anand shows Dara how we could one day use its resources to 3D print a moonbase.

Mysteries of the Abandoned
Some of the world's most incredible engineering projects now lie in ruins. These deserted places are home to extraordinary mysteries and untold secrets, and we revisit them to understand how they were built, and why they were abandoned.
They were once some of the most advanced structures and facilities on the planet, standing at the cutting-edge of design and construction. Today they are abandoned, dangerous, some of them even deadly. From uninhabited cities to empty factories, these long-forgotten engineering marvels are scattered around the globe. Science Channel uncovers why some of the world's most advanced architectural achievements were eventually left behind in the all-new series Mysteries of the Abandoned.
Each of the six, hour-long episodes of Mysteries of the Abandoned features stories behind engineering wonders, why they were built, and the reasons they were eventually left to crumble. Each story recalls the people who originally designed the structure, their historical significance, and why they were ultimately no longer of use. The premiere episode explores California's Goat Canyon Trestle railway, known as the 'Impossible Railroad,' that required the biggest wooden trestle bridge in the world; Ukraine's Duga, the notorious anti-ballistic missile radar, known as the 'Russian Woodpecker,' that still stands in within the Chernobyl Exclusion Zone; and the Grand Goulets Road in the French Alps, an astonishingly narrow and perilous mountain passageway.
