In today's climate debate, there is only one factor that cannot be calculated in climate models - humans. How can we nevertheless understand our role in the climate system and manage the crisis? Climate change is a complex global problem. Increasingly extreme weather events, rising sea levels, and more difficult living conditions - including for us humans - are already the order of the day. Global society has never faced such a complex challenge. For young people in particular, the frightening climate scenarios will be a reality in the future. For the global south, it is already today. To overcome this crisis, different perspectives are needed. "THE UNPREDICTABLE FACTOR" goes back to the origins of the German environmental movement, accompanies today's activists in the Rhineland in their fight against the coal industry and gives a voice to scientists from climate research, ethnology and psychology.

The 1960s was an extraordinary time for the United States. Unburdened by post-war reparations, Americans were preoccupied with other developments like NASA, the game-changing space programme that put Neil Armstrong on the moon. Yet it was astronauts like Eugene Cernan who paved the uneven, perilous path to lunar exploration. A test pilot who lived to court danger, he was recruited along with 14 other men in a secretive process that saw them become the closest of friends and adversaries. In this intensely competitive environment, Cernan was one of only three men who was sent twice to the moon, with his second trip also being NASA’s final lunar mission. As he looks back at what he loved and lost during the eight years in Houston, an incomparably eventful life emerges into view. Director Mark Craig crafts a quietly epic biography that combines the rare insight of the surviving former astronauts with archival footage and otherworldly moonscapes.

Comets pose one of the greatest threats to life on Earth - a threat that can only be countered if we find out more about them. In 2005, in an audacious bid to do just that, NASA scientists launched a space probe to collide with a comet in the emptiness of deep space. This film follows the amazing story of mission Deep Impact, from its inception through to the final nail-biting moments when the probe and comet Tempel 1 met head-on.

Laika, a stray dog, was the first living being to be sent into space and thus to a certain death. A legend says that she returned to Earth as a ghost and still roams the streets of Moscow alongside her free-drifting descendants. While shooting this film, the directors little by little realised that they knew the street dogs only as part of our human world; they have never looked at humans as a part of the dogs’ world.

A real-time reconstruction of time-lapse photographs taken on board the International Space Station by NASA’s Earth Science & Remote Sensing Unit. The film is scored with musical selections from three albums by Phaeleh (producer Matt Preston): Lost Time, Illusion of the Tale, and Somnus. The music directly influenced the choice of material used in the film. The film's duration is approximately the length of time it takes ISS to orbit the Earth once: 92 minutes and 39 seconds. Meditate on the beauty of our planet.
