On a bright, cold morning on 15th February 2013, a meteorite ripped across the skies above the Ural mountains in Russia, distintegrating into three pieces and exploding with the force of 20 Hiroshimas. It was a stark reminder that the Earth's journey through space is fraught with danger. A day later, another much larger 143,000 tonne asteroid passed within just 17,000 miles of the Earth. Presented by Professor Iain Stewart, this film explores what meteorites and asteroids are, where they come from, the danger they pose and the role they have played in Earth's history.
Landing humans on Mars will be hard, but keeping them alive will be even harder. NASA scientists are on the verge of designing some of the most innovative rockets and training the astronauts who will pilot them.
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.
Born of the Cold War, NASA moves stridently from disastrous rocket tests to the glorious conclusion of the Gemini Program. We experience the massive challenges of sending a man into space and how, despite many setbacks, the astronauts proved that the key element to exploration would be human resourcefulness, in space as well as on the ground. NASA veterans describe these early missions as the hardest of all - the first, uncertain steps towards a new frontier. Building on the success of the pioneering Mercury program, Project Gemini gives NASA the experience and confidence to take the next giant leap - to land men on the Moon.
Twelve billion miles away a tiny spaceship is leaving our solar system and entering the void of deep space. It is the first human-made object ever to do so. Slowly dying within its heart is a plutonium generator that will beat for perhaps another decade before the lights on Voyager finally go out. But this little craft will travel on for millions of years, carrying a Golden Record bearing recordings and images of life on Earth. The story of Voyager is an epic of human achievement, personal drama and almost miraculous success. Launched 16 days apart in 1977, the twin Voyager space probes have defied all the odds, survived countless near misses and almost 40 years later continue to beam revolutionary information across unimaginable distances. With less computing power than a modern hearing aid, they have unlocked the stunning secrets of our solar system. This film tells the story of these magnificent machines, the men and women who built them and the vision that propelled them farther than anyone could ever have hoped.
