In 1972, astronauts aboard Apollo 17 captured the iconic 'Blue Marble' photo of Earth, the first time the whole of the Earth had been captured within a single frame. At the time, this new perspective had a profound effect on our perception of ourselves; since then NASA has taken millions more. In this epic, powerful and revelatory film, a new generation of astronauts (including Tim Peake) uses those images of the earth from space to reveal the astonishing transformation humanity has wrought in the 45 years since 'Blue Marble'. Together the astronauts give us an armchair tour of the change they've witnessed from orbit, as they've watched us etching our presence on the planet. The film will show these images together in stunning time-lapse sequences to reveal how we are reshaping our world, for better and for worse - from the sprawling megacities of China to vast desert farms in the Middle East, and the melting snow cap of Kilimanjaro, to giant solar arrays in Nevada.d worse
