Horizon: Nasa's Mission to Mars

NASA’s Curiosity Rover is the biggest and most powerful ever launched. It is a mobile lab, packed with diverse scientific equipment, intended to answer the big question: Is Mars a suitable environment for life? HORIZON tells the story of this unique journey of scientific discovery, which could change the way we think about the iconic red planet. NASA’s previous research has already revealed that this frozen desert world of towering volcanoes and polar ice caps bears more resemblance to Earth than we’d ever thought possible.
