Scientists Are Looking Exploring Hibernation for Space Travel, Just Like 'Alien'
Everybody knows that familiar scene in sci-fi movies where the camera pans over a row of cryogenic chambers containing the crew members of a space ship, whether it's Planet of the Apes, 2001: A Space Odyssey, Avatar, or Alien. Though it's called many different things (hypersleep, cryosleep, etc.), the scientific term for this kind of long-term hibernation is 'torpor,' and a recent science symposium in New Orleans spent some time exploring how we can use it to travel to other planets.
Some of the biggest challenges for space travel are time and space. Not in the relativistic sense—the practical sense. Travelling anywhere outside our own solar system is going to take a huge amount of time, even if it's our closest neighbor, Alpha Centauri. NASA has an unmanned mission planned to head out there in 2069, but even if the spacecraft manages to reach its projected speed (which is 10% of the speed of light), the craft will still take 44 years to reach Alpha Centauri (the star system is 4.4 light years away). Apart from arriving on alien planets in their 70s, the long travel time to other planets poses another problem for astronauts: food and water. The longer the trip, the more supplies a spaceship needs to carry to sustain its crewmembers.
