The European Space Agency is looking into possibly putting humans into a suspended animation state…kind of like hibernation for animals, for future space flight. I.E.. Going to Mars, which would take approximately 180 days.
They say that slowing down a humans metabolic rate isn’t exactly possible yet, but it would help with the long space flight. Jennifer Ngo-Anh, the research team head says the idea “is actually not so crazy.” Some trauma victims actually are put through a similar process.
The Astronauts would have to ‘Fatten” up a little bit while “hibernating” and the space ship would be operating autonomously for most of the flight.
