This is the story of the most extraordinary journey in human exploration, the Voyager space mission. In 1977 two unmanned spacecraft were launched by NASA, heading for distant worlds. It would be the first time any man-made object would ever visit the farthest planets of the solar system - Jupiter, Saturn, Neptune and Uranus. On the way the Voyagers would be bombarded by space dust, fried by radiation and discover many of the remarkable wonders of the solar system. Now, at the end of 2012, 35 years and 11 billion miles later, they are leaving the area of the sun's influence. As they journey out into the galaxy beyond they carry a message from Earth, a golden record bolted to the side of each craft describing our civilisation in case of discovery by another. This is the definitive account of the most intrepid explorers in Earth's history.

Join structural engineer Steve Burrows and his team of laser-scanning experts as they set out to explore the epic building legacy of Jerusalem. Their focus is on two of the most impressive engineering creations of the ancients: the Temple Mount, a holy icon larger than 20 football fields, and the man-made mountain of Herodium, an opulent palace built on top of millions of tons of hand carved rock. Both structures were created by King Herod the Great - known as one of history's most reviled characters, but also known for his visionary engineering. From the iconic Wailing Wall to deep into the dangerous West Bank, Steve and his team travel across Jerusalem and beyond on the trail of King Herod's remarkable building ambitions. Using cutting-edge laser technology to analyze constructions made at the time of Christ, they discover new revelations about the skills of Herod's ancient builders, and answer long held mysteries about his magnificent structures.
