Horizon: New

With the dream of sending humans to Mars closer than ever before, Horizon has gathered the world's leading experts on Mars and asked them where they would go if they got the chance - and what would they need to survive? Using incredible real images and data, the programme brings these Martian landmarks to life - from vast plains to towering volcanoes, from deep valleys to hidden underground caverns. This film also shows where to land, where to live and even where to hunt for traces of extraterrestrial life. This is the ultimate traveller's guide to Mars.
