Cassini-Huygens has given us a more detailed account of Saturn than we could have ever imagined. Breathtaking images of Saturn and its sparkling rings, a massive 6-sided polar storm, and 62 moons - including the most bizarre worlds in our Solar System -- we have seen them all thanks to Cassini.

Second Genesis follows planetary scientist Carolyn Porco as she explores what it takes to look for life beyond Earth, and what conditions are required for life to exist. Porco makes the case that Saturn’s moon Enceladus—with its plumes of water vapor spewing into space, confirmed organic materials, and evidence of hydrothermal vents at the bottom of its liquid ocean—is the most promising place to look. Could Enceladus be the key to proving once and for all that life is not unique to Earth? And what it would mean—both scientifically, and spiritually—if we found evidence of a true second genesis right here in our own galactic back yard?

In 1972, the crew of Apollo 17 captured the iconic 'Blue Marble': the first photograph ever taken by an astronaut of the entire Earth. This photo had a profound effect on our perception of ourselves. Since then, Nasa has taken millions more. In this epic, powerful and revelatory documentary, a new generation of astronauts, including Tim Peake, use 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 provide an armchair tour of the change they've witnessed from orbit, as humankind etches our presence on the planet. Using stunning time-lapse sequences, the programme reveals 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 from the melting snowcap of Kilimanjaro to giant solar arrays in Nevada.

When Apollo astronaut Gene Cernan stepped on the Moon in December 1972 he left his footprints and his daughter's initials in the lunar dust. Only now, over forty years later, is he ready to share his epic but deeply personal story of fulfillment, love and loss. Cernan's burning ambition carried him from a quiet Chicago suburb to the spectacular and hazardous environment of space, and ultimately, to the Moon. Five years in the making, The Last Man on the Moon unveils a wealth of rare archive material, and takes Cernan back to the launch pads of Cape Kennedy, to Arlington National Cemetery and to his Texas ranch, where he finds respite from a past that refuses to let him go.
