Sep 24, 2014 Season 42 Episode 2 watch on (Paid)

Our lives are going digital. We shop, bank and even date online. Computers hold our treasured photographs, private emails, and all of our personal information. This data is precious — and cybercriminals want it. Now, NOVA goes behind the scenes of the fast-paced world of cryptography to meet the scientists battling to keep our data safe. They are experts in extreme physics, math and a new field called "ultra-paranoid computing," all working to forge unbreakable codes and build ultra-fast computers. From the two men who uncovered the world's most advanced cyber weapon to the computer expert who worked out how to hack into cash machines and scientists who believe they can store a password in your unconscious brain, NOVA investigates how a new global geek squad is harnessing cutting-edge science — all to stay one step ahead of the hackers.

Welcome to Mars

Jan 04, 2005 Season 32 Episode 9

Go inside mission control and explore Mars with rovers Spirit & Opportunity. On January 3, 2004, a rover named Spirit crash-landed on the surface of Mars and sent its first message home. The elation of the assembled scientists as well as the engineering story leading up to the landing were captured by NOVA in its popular documentary "MARS Dead or Alive." That elation is the starting point for the sequel, "Welcome to Mars," which follows the adventures of Spirit and Opportunity on the Red Planet. NOVA's producers enjoyed unprecedented access to the mission scientists at NASA's Jet Propulsion Laboratory as they wrestled with the technical crises that soon beset the rovers. All goes well until Spirit suddenly falls silent and then, inexplicably, starts spewing gibberish. For three agonizing days the engineers struggle to regain control of the unhinged rover before they finally solve the problem. Then Opportunity lands and sends back the image of an outcrop of bedrock just a few yards away. The rock turns out to be a crucial clue in the quest to discover if there was once water and life on Mars. Eventually, the evidence adds up, and after 40 years of speculation, NASA finally announces solid proof that Mars was once awash in water. "Welcome to Mars" presents a compelling inside story of triumph and technical ingenuity, with stunning fresh images from an alien world.
