#3 - Man on Mars - Mission to the Red Planet
Horizon - Season 2014 - Episode 3
Horizon goes behind the scenes at Nasa to discover how it is preparing for its most ambitious and daring mission: to land men - and possibly women - on the surface of Mars. It's over 40 years since Neil Armstrong made the first human footprint on the moon. But getting to the red planet would involve a journey of at least three years. Horizon meets the scientists and engineers who are designing new rockets, new space suits and finding ways to help astronauts survive the perils of this long voyage. And it turns out that having the 'right stuff' for a mission to mars might not be quite what you expect.

History Channel Documentaries - Season 2008 - Episode 36
The litany of disasters reads like the Apocalypse: melted ice caps, submerged coastal cities, prairies turned to deserts. Mass extinctions.

A GLOBAL WARNING? spans the globe — fourteen extreme locations in all — to survey the frontline of scientific research and climatic impact.

Understand, with the help of exacting animations, how sun activity, volcanic eruptions, meteor impacts, and even continental drift have made huge differences in the earth's weather systems.
