This documentary recounts the audacious 1991\u00a0Biosphere 2 experiment<\/strong><\/a>\u00a0– an engineered greenhouse in the Arizona desert simulating the ecological conditions on Earth, initiated to test the prospects of space colonisation. Eight ‘Biospherians’ volunteered to be locked into the structure for this real time experiment over two whole years!<\/p>\n

Directed by\u00a0Matt Wolf<\/strong><\/a>,\u00a0Spaceship Earth<\/strong>\u00a0documents the quixotic two year space odyssey; how the Biospherian’s grew their own food, researched and maintained Biosphere’s 2’s ecosystems, and how they managed – or didn’t – with the psychological stresses and strains through such a protracted period. When the two years were up, just how well the eight volunteers navigated their extended foray into earthbound outer space, as much as the success of the experiment whole, is dramatically retold.<\/p>\n

With an after-film discussion with Biospherian’s\u00a0Abigail Alling<\/strong>\u00a0(Gaie) and\u00a0Mark Van Thillo\u00a0<\/strong>(Laser)<\/p>\n

To find out more about the Biosphere 2 story take a look at the official website<\/a> or the in-depth Wikipedia<\/a> page. Rebecca Reider\u2019s Dreaming the Biosphere<\/em><\/a>. <\/em>(University of New Mexico Press, 2009) provides a fascinating account of the project, written by a sympathetic outsider.<\/p>\n

You really don\u2019t have to look any further than Biosphere 2. The photos below, courtesy of ecologist, Biospherian and director of the Institute of Ecotechnics<\/a>, Mark Nelson<\/a>, illustrate something of the life inside the vast space frame for the Biospherians, growing, testing, data recording and conducting scientific and technical experiments.<\/p>\n

Apart from picture 3 the photos above are part of Biospherian and director of the Institute of Ecotechnics, Mark Nelson’s archive, used originally for a research paper. These are the captions that have come with the photos. <\/sup><\/p>\n

5 – ‘The lousiest job but we did it to safeguard the health of the ocean: cleaning mats in the algae scrubber room’.<\/sup><\/p>\n

6 – ‘The care and weeding of your coral reef ocean. Gaie (Abigail Alling) checking the reef and removing algae. Eleven pounds a week were removed, helping the corals retain access to the light they need for photosynthesis.’<\/sup><\/p>\n

7 – ‘Sharing some of the stories with Oleg Gazenko and John Allen. Gazenko was the unofficial confidante and psychologist for generations of Russian cosmonauts. His opinion was that he’d seen much worse conflict amongst Russian space crews! His observations indicated the Biospherians had fully adapted to our environment’ – photo Marie Harding<\/sup><\/p>\n

8 – ‘Team of glaziers working on the glass space frames. They installed over six thousand, six feet on a side. This work was often done at night because of blazing daytime temperatures. Many of the space frame crew were rock-climbing mountaineers’ – photo Peter Menzel<\/sup><\/p>\n
