In RIDLEY Scott’s 1979 film “Alien,” fictional astronauts are put into a long slumber to traverse the vast expanse of space.
Now an investigation from the European Space Agency has stated that hibernation may be the best way to send astronauts to Mars.
The agency explained in a report Monday that when bears hibernate, they use fewer resources without letting muscle and bone go to waste.
Hibernation would be one way to prevent wasting, which happens because astronauts don’t use their muscles as much when working in zero gravity.
Explorers kept in hibernation will also need less food and water to sustain life, saving space and fuel costs.
“Human hibernation extends beyond the realm of science fiction and could become a game-changing technique for space travel,” ESA wrote in its report.
“Astronauts hibernation could be the best way to save on mission costs, reduce spacecraft size by a third and keep crews healthy en route to Mars.”
ESA scientists explain how hibernation during a month-long trip can work in a journal article A review of neuroscience & behavioral biology.
Crew members will sleep in the capsule, take medication, and let the ship handle its operations for most of the flight.
Soft pods need to be in a quiet environment with low light, high humidity and kept at a low temperature below 10C.
The astronauts will move very little, but will be unrestricted and dressed to prevent overheating, the ESA said.
They will be attached to wearable sensors to monitor their posture, temperature and heart rate.
The idea would be to reduce astronauts’ metabolisms during flight, a process that could take anywhere from three to nine months.
Missions to Mars will require about two years’ worth of food and water, the equivalent of 30kg of supplies per astronaut per day.
During hibernation, the crew’s metabolic rate will drop to 25% of their normal state, drastically cutting down on supplies and required space.
It would also avoid the issue of being involved in crew squabbles and cabin fever on the long and suffocating interplanetary voyage.
Study co-author Jennifer Ngo-Anh said: “Where there is life, there is stress.
“This strategy will reduce the boredom, loneliness, and levels of aggression associated with being confined to a spacecraft,” she added.
Although about 34 million miles away, Mars is the closest, most Earth-like world to us, and space agencies have been keeping an eye on it for decades.
So far, only Nasa and China’s space agency have successfully landed anything on the Red Planet – all unmanned robots.
Along with billionaire Elon Musk’s SpaceX, they are racing to be the first to launch crewed missions to our hospitable neighbor, possibly around the 2030s.
Whoever gets there first will have a tough test ahead if they plan to stay on the surface for very long.
The atmosphere on Mars is 95% unprocessable carbon dioxide, and temperatures on winter nights can drop as low as -140C.
Mars is 1/10th the mass of Earth, so gravity is only 1/3 of the pull we experience. It is frequently hit by high winds and dust storms.
Astronauts will likely need to survive on the surface for three months before Mars is close enough to Earth to make a return flight.
