Follow Dr. Ben Longmier and his team into the rugged Alaskan wilderness on a quest to build a whole new type of rocket engine. Their goal is to test sensitive components by launching them into radiation-filled environments of space aboard helium balloons. Their goal is to revolutionize space travel and exploration by harnessing the energy contained in the dynamic fourth state of matter: plasma.

The first episode of Space Voyages looks at the Mars Curiosity Rover - an incredible 21st century machine. And it would never have been possible without the accomplishments of early NASA astronauts and engineers. Everything was new – rocket science, astronaut survival – even simply steering in space! This is the story of how both humans and robots laid the foundations for space exploration that continues today.

On Earth and in the Universe, size matters, but it matters in different ways. In Space, bigger is not necessarily better.
Witness some of the most violent impacts in the universe, and meet the people protecting us from the fallout of these cosmic collisions.
S2E2 • Extreme Universe • Astronomy
There is a new kind of weather to worry about, and it comes from our nearest star. Scientists are expecting a fit of violent activity on the sun which will propel billions of tonnes of superheated gas and pulses of energy towards our planet. They have the power to close down our modern technological civilisation - e.g. in 1989, a solar storm cut off the power to the Canadian city of Quebec. Horizon meets the space weathermen who are trying to predict what is coming our way, and organistions like the National Grid, who are preparing for the impending solar storms.
