Mars astronauts will hibernate for a 50 million-mile journey in space The Belfast Telegraph

It was once the preserve of science fiction books and films but scientists now believe that they will be able to develop ways of sending people on long space journeys in hibernation. The European Space Agency is funding research into what has become the holy grail of space travel – a method that will allow astronauts to spend months or years in suspended animation. The agency hopes to create a hibernation system for a planned manned mission to Mars in 2033.
