Fireball: Visitors from Darker Worlds

Challenger Disaster: Lost Tapes follows the story of the Space Shuttle Challenger and its crew, specifically Christa McAuliffe, the first civilian to be launched into space. The events of the days leading up to the disaster are detailed in this unique film, which uses no narration and no interviews. Instead the story is told solely with reports of journalists covering the story, extensive recordings from the NASA team, and interviews with McAuliffe and others who were part of this one-of-a-kind mission. Using rarely seen images and audio recordings, this show takes viewers behind the scenes of this compelling and historic story in a way never before seen.

A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography.

A film from which you can learn about the first progress of the USSR in space exploration, as well as about the achievements of Yuri Gagarin, the world famous first cosmonaut, who was the very first to conquer the depths of space. This is an educational documentary film for people of all ages. And for those who are nostalgic about the past, and for those who want to learn more about space and its conquest.

They have no roots, no seeds, no flowers, but mosses show immense survival capacities and can suspend their biological activity for long periods. Today, researchers are exploring the exceptional resistance of these archaic organisms. British ecologists have even resurrected a "zombie" moss that has been trapped in the permafrost for 1,500 years. Associated with decay and disliked in Europe, mosses are deified in Japan. With 25,000 species worldwide, bryophytes - their scientific name - are the seat of real ecosystems, and can develop in inhospitable landscapes, through an extravagant reproduction cycle.

The biggest tech revolution of the 21st century isn’t digital, it’s biological. A breakthrough called CRISPR gives us unprecedented control over the basic building blocks of life.

This documentary is a provocative exploration of CRISPR’s far-reaching implications, through the eyes of the scientists who discovered it, the families it’s affecting, and the genetic engineers who are testing its limits.

With a million species at risk of extinction, Sir David Attenborough explores how this crisis of biodiversity has consequences for us all, threatening food and water security, undermining our ability to control our climate and even putting us at greater risk of pandemic diseases.
