A billion miles from Earth, Titan is a tantalizing alien world. Could clues to the origins of life or even living microbes be hidden under its thick orange clouds? Saturn’s largest moon has a soupy atmosphere resembling Earth’s billions of years ago, and may help reveal how life got started and whether it exists on other worlds.

But discovering Titan’s secrets demands a bold and ambitious space mission. It took seven years for top US and European scientists to design and build the ingenious Cassini-Huygens space probe. Take a front-row seat at Mission Control to watch the launch and the crises that threaten the probe on its perilous voyage across the solar system.

Along the way, Cassini captures astonishing images of Saturn’s rings and many new clues to their mysterious beauty. The climax comes with the touchdown on Titan. As Huygens penetrates the orange haze, it unveils a bizarre landscape drenched in liquid methane, more surprising than the scientists ever suspected.

Filled with incredible images beamed back during the mission, NOVA takes a dramatic voyage of discovery to an exotic world unimaginably far from our own.
