Space Tourists airs tonight on the Documentary Channel at 8pm & 11pm

When Anousheh Ansari boarded the International Space Station on September 20th, 2006, she became the first self-funded female, the first Iranian citizen, and the fourth human overall to enter the Earth's orbit as a coveted 'space tourist'.

After building and selling a large telecom business, Ansari had decided that she would pay over $20 million USD to take a ride on the Russian Soyuz TMA-9 and orbit Earth as a crew member of the International Space Station for 8 days. While training as a backup for Daisuke Enomoto, who failed to meet the required medical qualifications, Ansari was notified that her lifelong dream would be fulfilled - with only one month remaining before liftoff.

Meanwhile, without Ansari's knowledge, a charismatic Swiss filmmaker had begun to collect material for a documentary that explored the peculiar circumstances of the Russian space tourism industry. Gathering footage at the Yuri Gagarin Cosmonaut Training Center in Star City, Russia and at the Baikonur Cosmodrome (the Soyuz's launch facility), filmmaker Christian Frei began to lay the foundation for what would become the first documentary to uncover a highly exclusive and secretive world.

The finished product, Space Tourists, debuted in the US at the 2010 Sundance Film Festival. Thought it never had an overwhelming reception in North America, it is arguably one of the most fascinating travel-themed documentaries to have been produced in recent years and a must-see for anyone with a sense of adventure or a distant dream of venturing to space.

Frei's film uncovers many facets of the Russian space tourism program that are especially compelling to watch unfold on the big screen.

From the pre-launch rituals at the Baikonur Cosmodrome, to the group of men that make a living by hunting down and recovering the enormous scrap metal that falls to Earth from every Soyuz launch; Frei's film captures an incredible spectrum of physical environments, people/cultures, and brilliantly contrasts the magnificence of spaceflight in direct contrast with the trivial hardships of life on Earth.

It's a film that's both visually arresting and offers to bring the viewer on a journey with each of the characters that it follows - from training to touchdown and everywhere in between.

Space Tourists is currently being featured on the Documentary Channel airing tonight at 8pm and 11pm, or available on DVD via the Documentary Channel online store.
