This episode discusses the human exploration of Antarctica, in particular the mission led by Captain Robert Falcon Scott, whose team died on the way back from the South Pole. It shows the scientific work in the modern human bases in Antarctica, especially Mawson Base and its observation of Adelie Penguins (partially through tracking devices). The second half of the episode describes how the series was made. Most crucial was of course the camera work. To get access to the wildlife of the sea, for example, boats, divers, suspended capsules and remotely controlled cameras mounted on inflatables were used. Particularly dangerous to divers were Leopard Seals and other predators. The film concludes that although working in Antarctica is now much easier than during the early days of exploration, human footsteps on the continent are still exceedingly rare in part because of international treaties prohibiting industrial exploitation.

Follow the dramatic personal journey of Hugh Herr, a biophysicist working to create brain-controlled robotic limbs. At age 17, Herr’s legs were amputated after a climbing accident. Frustrated by the crude prosthetic limbs he was given, Herr set out to remedy their design, leading him to a career as an inventor of innovative prosthetic devices.
Now, Herr is teaming up with an injured climber and a surgeon at a leading Boston hospital to test a new approach to surgical amputation that allows prosthetic limbs to move and feel like the real thing. Herr’s journey is a powerful tale of innovation and the inspiring story of a personal tragedy transformed into a life-long quest to help others.

In space travel there is a saying that the first 50 miles and the last 50 miles are the most dangerous. Explore the controlled explosion of launch, the fiery crucible of re-entry and everything in between. See how a single spark inside a spacecraft or a micrometeoroid less than an inch wide hitting a space station can turn a routine mission into a lethal nightmare. As the missions become longer, venturing to Mars and beyond, the potential disasters will only become bigger. What would happen if a spacecraft ventured too close to a black hole or was hit by a gamma ray burst?

Bonnie and Marshall - 'Ti' and 'Do' turn to recording their lessons to teach their followers how to transcend, and the intense rule and check partner system is set-up. The renaming of the members, the haircuts, and the clothing style also are changed to fit an androgynous look.
When Ti is given a cancer diagnosis, the dynamic of the group changes. After Ti dies from cancer in 1985, a distraught Do briefly allows members to visit their families. When the members return, Do becomes more controlling.

Under the management of new team principal Otmar Szafnauer, Alpine F1 Team goes into 2022 retaining their drivers Fernando Alonso, a veteran of Team Enstone and two-time Champion, and Esteban Ocon, the driver who took Alpine to their first victory since 2014, with a new reserve driver in Australian driver and 2021 Formula Two champion Oscar Piastri. Alpine scores consistent points scores in Miami, Baku, and Austria.
By the French round - the home race of Alpine - McLaren and Alpine are tied for sixth in the Constructors' Championship. Early into the race, Alonso edges past Lando Norris for fourth, with Ocon behind him. However, Ocon inadvertantly takes Yuki Tsunoda out of the race, giving him a five-second penalty. Pitting soon after drops him down out of the points, with Alonso now sixth and a second behind Norris. Alonso holds the McLarens up to buy enough time for Ocon to pass them. Alonso finishes sixth and Ocon eighth in their home race.
Before Hungary, it is revealed that four-time Champion Sebastian Vettel will retire from Formula One, sending the paddock and media into a frenzy with the prospect of a ‘silly season’ on the horizon for Aston Martin; Szafnauer is adamant that Alonso is staying with Alpine for 2023. Hungary is the make-or-break round for Alpine - both drivers need to score higher points than McLaren to achieve fourth in the Constructors' Championship. Ricciardo and Lance Stroll both overtake the Alpines, but Ricciardo punts Stroll off the track, giving him a five-second penalty. Alonso and Ocon barely hold on to the points, and Ricciardo finishes fifteenth after his penalty, allowing Alpine to secure fourth place. The team and their title sponsors BWT celebrate at a sponsor dinner. The next day, Alonso reveals he had received a call from Aston Martin team owner Lawrence Stroll to replace the outgoing Vettel, moving him out of Team Enstone. Left with no other option, Alpine announce Piastri for the 2023 season, and McLaren are looking to replace Ricciardo with Piastri, who they have had eyes on. To make matters worse for Alpine, Piastri announces on Twitter that he will not be driving for the team, considering he had not signed such a contract with them.
