The 8th episode reviews Giovanni Cassini's life. His observations of Saturn and its moons would have an enduring effect on the scientific world. Neil deGrasse Tyson also narrates the mysterious untold story of the scientist who figured out how to go the Moon while fighting for his life in a WWI trench. Aleksandr Shargei changed his name to Yuri Kondratyuk out of fear for his life and wrote a manuscript on rocket motion and space colonization. This letter would end up capturing the attention of an engineer working on the Apollo program, John Houbolt, and would made the Apollo Mission possible.
We will also know the saga of the twenty-year long odyssey of Cassini-Huygens spacecraft, a robotic explorer ordered to commit suicide on another world.

The world’s first flying car might be on the market sooner than we think, and as a new, cutting-edge invention goes through a series of gruelling tests, behind-the-scenes access reveals the secrets of this sci-fi innovation. With the ability to carry up to 250 kg (551 lb) of payload at speeds up to 80 km/h (50 mph), the 12-rotor Seraph is developed by the Bristol-based company aptly named Vertical Aerospace, and is the Britain's leading electric VTOL (vertical take-off and landing) air taxi candidate.

NASA's brand-new Mars rover is on the hunt for alien life, and with the help of cutting-edge engineering, scientists embark on a search for fossilized remains, which might prove the Red Planet was once home to a vast ocean and extraterrestrial life. Perseverance carries seven scientific instruments to study the Martian surface at Jezero crater. It carries several cameras and two microphones. The rover is accompanied by the helicopter Ingenuity, which will help Perseverance to scout for locations to study.

Set in the dark underbelly of Silicon Valley, The Social Dilemma fuses investigative documentary with enlightening narrative drama. Expert testimony from tech whistle-blowers exposes our disturbing predicament: the services Big Tech provides-search engines, networks, instant information, etc.-are merely the candy that lures us to bite. Once we're hooked and coming back for more, the real commodity they sell is their prowess to influence and manipulate us.

From the first transistor to deep learning networks, the rise of computing power over the last 50 years has been so phenomenal it's changed everything from the way we communicate to how our appliances interact. Fuelled by giant leaps forward in computer technology, the race is on. As the progress of machines continues to accelerate, so will the pace of change.

Over the last years, the world has experienced an energy revolution, driven by an urgent need to green the grid and save life on Earth as we know it. 50 years ago, a devastating oil crisis kicked off an energy revolution. The world set course to cut the costly habit of burning fossil fuels. With the urgent new threat of a changing climate, the drive to unleash the power of the sun, earth and wind has accelerated into a race for humanity's survival. Change is taken place but, is it happening fast enough to secure our future? Technologies are right here, right now, and they will enable the transition to 100% renewables, because winning the energy race means a win for the entire world.
