Early in the life of the solar system, Mars appears to have had Earth-like conditions. Planetary researchers have been targeting Mars to gain insight into how our own planet developed.

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.

Before spaceflight aviators began wearing pressure suits to allow them to function at higher ceilings. These aviation suits were adapted for the early Cosmonauts and Astronauts but as requirements became more demanding spacesuit design became more elaborate.

For most of human history, our neighboring planets were little more than dots of light in the sky with comets and asteroids being a complete mystery. Today the smaller rocky planets and asteroids are seen as the key to understanding the formation of our planetary system.

The Sun is our star. Its energy enables life on the Earth to thrive yet we know so little about the solar weather and the 11-year solar cycle. Modern technology can be adversely affected by giant coronal mass ejections and there appears to be a link between sunspot activity and climatic conditions.

Space telescopes orbiting above the distorting effects of the Earth’s atmosphere, such as the Hubble, have made incredible contributions to our knowledge of the universe.

There are so many unanswered questions about the stars, the galaxies, and the universe and just mapping what lies in the night sky is immensely difficult. This episode looks at the effort involved in making the first photograph of a black hole and the search for planets orbiting distant stars.

As our expertise in space technology increases, there have been spin-offs in many areas: particularly in communications. This episode examines the profit-making satellite telecommunications industry and emerging techniques designed to increase the rates of data transmission from distant space probes

The most important planet in the solar system is our home, the Earth. It is the only planet we know that harbors life. This episode looks at the growing understanding of the Earth’s complex climatic systems and the part on-orbit observation plays in the growth of knowledge about our planet.
2021 • Technology
Space technologies are continuing to be refined and access to space is becoming cheaper. This episode looks at the development of new human-rated spacecraft, reusable boosters, laser communications, the Ion Drive, and new techniques to refuel satellites in space.

Explores state surveillance and digital social control in China by following the experiences of two families and a journalist. Zijuan Chen is fighting for the release of her imprisoned husband, human rights lawyer Weiping Chang, while trying to keep his memory alive for their son. Wenzu Li and her newly freed husband, Quanzhang Wang, struggle against surveillance that is not only stopping him from being able to work but also affecting ordinary tasks like taking their son to school. Journalist Sophie Xueqin Huang, a pivotal figure in bringing the Me Too movement to China, is at constant risk of arrest. Chinese film-maker Jialing Zhang gives an exclusive and previously impossible intimate insight into the interior of China and tells a deeply disturbing story of how the state uses technology to control its citizens as well as propaganda to convince its people to trust it.

The world's most iconic buildings were built in the heyday of the American century, and as New York became the capital for these innovative new skyscrapers, experts used cutting-edge tech to push engineering to new heights.
S1E2 • Skyscrapers Engineering the Future • 2019 • Technology
Artificial intelligence is examined. Included: the effort to build intelligent machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power.

Only in the last 200 years have humans learned how to make things cold. Steven Johnson explains how ice entrepreneur Frederic Tudor made ice delivery one of the biggest export business in the U.S. and describes the place where Clarence Birdseye, the father of the frozen food industry, experienced his eureka moment. He also travels to Dubai to see how mastery of cold has led to penguins in the desert. From IVF to food, politics and Hollywood to human migration, the unsung heroes of cold have led the way.

Professor Jim Al-Khalili looks at how we have created machines that can simulate, augment, and even outperform the human mind - and why we shouldn't let this spook us. He reveals the story of the pursuit of AI, the emergence of machine learning and the recent breakthroughs brought about by artificial neural networks. He shows how AI is not only changing our world but also challenging our very ideas of intelligence and consciousness. Along the way, we'll investigate spam filters, meet a cutting-edge chatbot, look at why a few altered pixels makes a computer think it's looking at a trombone rather than a dog and talk to Demis Hassabis, who heads DeepMind and whose stated mission is to 'solve intelligence, and then use that to solve everything else'. Stephen Hawking remarked 'AI could be the biggest event in the history of our civilisation. Or the worst'. Jim argues that AI is a potent new tool that should enhance our lives, not replace us.

Mars has beckoned humankind for centuries, but only in the last 50 years have we begun to scratch its surface. The latest Martian explorer is Perseverance, an uber-sophisticated rover, chock-full of scientific instruments, including 23 cameras, a robotic arm, lasers, and spectrometers, designed to analyze the terrain and reveal if there was ever life on the Red Planet. Join us as we examine the latest rocket, rover, and interplanetary helicopter.
