Since its formation in the early 60’s, NASA has continued to be the leading power in space exploration. Working with other space agencies, it has contributed substantially to the ongoing exploration of our universe, achieving incredible firsts that span the decades.
Europa - an icy moon of Jupiter 485 million miles away from Earth - may be our best hope for finding alien life in our solar system. Everywhere we find water on Earth, we find life. What does this mean for the search for life beyond Earth? Scientists believe that on Europa there is a liquid ocean buried beneath its icy crust. To find out if this alien ocean holds life, well need to get there, penetrate the ice shell, and navigate in an alien sea. In this episode of Explorer, well plunge headlong into the challenges of discovery on an alien world. Well meet the scientists, adventurers, and engineers who are determined to launch a mission to Europa - and follow them through the challenges, frustrations, and triumphs that come with planning a distant mission to an alien world. Through high-end CGI and quests to the edge of our planet, well go on a journey to and alien moon called Europa. To answer the basic question: Are we alone in the universe?

Volcanoes have long helped shape the Earth. But what is less well known is that there are volcanoes on other planets and moons that are even more extraordinary than those on our own home planet. Horizon follows an international team of volcanologists in Iceland as they draw fascinating parallels between the volcanoes on Earth and those elsewhere in the solar system. Through the team's research, we discover that the largest volcano in the solar system - Olympus Mons on Mars - has been formed in a similar way to those of Iceland, how a small moon of Jupiter - Io - has the most violent eruptions anywhere, and that a moon of Saturn called Enceladus erupts icy geysers from a hidden ocean. Computer graphics combined with original NASA material reveal the spectacular sights of these amazing volcanoes. Along the way, we learn that volcanoes are not just a destructive force, but have been essential to the formation of atmospheres and even life. And through these volcanoes of the solar system, scientists have discovered far more about our own planet, Earth - what it was like when Earth first formed, and even what will happen to our planet in the future.
The fate of the Mars InSight lander will all come down to a fiery seven-minute freefall into the Red Planet. Will it survive and reveal new insight into our planetary neighbour, or will the atmosphere of Mars prove to be too much for our new planetary explorer?
