The story of oceans is the story of life. Oceans define our home planet, covering the majority of Earth’s surface and driving the water cycle that dominates our land and atmosphere. But more profound still, the story of our oceans envelops our home in a far larger context that reaches deep into the universe and places us in a rich family of ocean worlds that span our solar system and beyond.
Robotic probes cast into the depths of space over the past two decades have made one thing crystal clear: Our solar system is a very wet place. Surveys of the giant planets Jupiter, Saturn, Uranus and Neptune have exposed the secrets of their enigmatic moons. And some of them, it turns out, harbor hidden oceans locked inside a shell of ice.
In the next decade, NASA is planning to send a spacecraft on repeated flybys of Europa -- an icy moon of Jupiter that looks something like a cue ball -- to learn whether it possesses the right ingredients for life.
Boats and blimps might one day be deployed on Saturn's moon, Titan, to navigate its methane lakes and its smoggy, hydrocarbon-rich atmosphere.
Geysers on Saturn's dynamic moon, Enceladus, spew the contents of its subsurface ocean far into space; a future mission could sweep up these "free samples," while a surface-crawling robot might plumb the depths of the geysers themselves.
Join us as we take a fascinating journey to each of these wet, icy worlds, and learn why scientists say they are some of the best places in the solar system to search for life beyond Earth.
