For several decades man have prepared for long voyages into space and to
settle other planets.
The challenge is enormous. To secure survival on a long journey we need
to "Bring Life to Space", and scientists have been trying to copy
Earth's delicate ecological balances in small, sealed cycles, to prepare
the production of sufficient and vital supplies of water, oxygen and
food on a journey into space. This historical documentary takes us back
to the 1960s and reveals unique footage from Russian experiments, where
people were confined for one year in a sealed spaceship mock up. The
documentary also reveals the extraordinary American experiment,
"Biosphere 2" back in 1991, where a group eight persons were isolated
for two years in a huge glass construction which contained a small scale
model of planet Earth. And it covers the recent Russian/European
experiment "Mars 500", where a mixed crew of six people is locked up in a
metal tube to simulate a 500 day trip to Mars.
