Dubai's Burj Khalifa is over 2,700 feet high and the tallest building in the world, and as engineers race to top this record-setting height with cutting-edge tech, a new 3,200-foot-tall building in Saudi Arabia is poised to take the crown.
After the success of the first manned moon landing, NASA ups the stakes by aiming for a new destination tens of millions of miles away: Mars. This is the inside story of Project Viking. Witness the overwhelming challenges engineers and scientists faced, not only to reach the Red Planet, but to land their spacecraft and deploy computer-operated experiments to answer the universal question: Is there life beyond Earth?
From the Stone Age to the Silicon Age, materials have helped drive forward our civilisation. By manipulating materials we have been able to transform our world and our lives - and never more so than in the past century when we have discovered and designed more materials than at any other time in human history. (Part 2: Plastic) Professor Mark Miodownik tells the story of plastics - created in the lab, they have brought luxury to the masses and shaped the modern age. He recounts tales of the mavericks responsible for some of plastic's most outrageous failures and heady successes, from the explosive attempts to make a replacement for ivory billiard balls to the ultimately ubiquitous Bakelite. Investigating at atomic level, Mark discovers the properties that have allowed plastics to dominate our world and reveals how the next generation of plastics will take its inspiration from nature, creating man-made materials which behave as though they are alive and which could help rebuild the human body.
The development of reliable, high-powered boosters has enabled researchers to send probes to distant planets. Without these workhorses, our science would remain tied to the Earth. This episode examines a range of launchers that are integral to space research.
