ASTRONAUTS could be put into artificial hibernation for trips to Mars, scientists predict.
Films such as Aliens and Interstellar show men and women being placed in deep freeze like animals hibernating.
Now experts are meeting in New Orleans to discuss how the process can be artificially copied for astronauts travelling huge distances.
Dr Matthew Regan of the University of Wisconsin School of Veterinary Medicine said: “It could protect them from space-related health hazards and reduce demands on a spacecraft’s power capacities.”
The theory is hibernating crew are kept alive over vast cosmic distances reducing the need to take along huge stocks of food and water.
This means spacecrafts do not have to be so big and missions are cheaper while astronauts don't get bored as they traverse long distances of space.
The symposium in New Orleans will explore how synthetic torpor might be induced by the brain, its similarities and differences to sleep, and how it could benefit astronauts.
