- Did you know that ESA is researching human hibernation for long distance spaceflight to Mars or beyond?
Hibernating astronauts could be the best way to save mission costs, reduce the size of spacecraft by a third and keep crew healthy on their way to Mars. An ESA-led investigation suggests that human hibernation goes beyond the realm of science-fiction and may become a game-changing technique for space travel.
When packing for a return flight to the Red Planet, space engineers account for around two years’ worth of food and water for the crew.
Torpor during hibernation is an induced state that reduces the metabolic rate of an organism. This ‘suspended animation’ is a common mechanism in animals who wish to preserve energy.
Reducing the metabolic rate of a crew en route to Mars down to 25% of the normal state would dramatically cut down the amount of supplies and habitat size, making long-duration exploration more feasible.
Mimicking therapeutic torpor, the idea of putting human into a state of hibernation, has been around in hospitals since the 1980s - doctors can induce hypothermia to reduce metabolism during long and complex surgeries. However, it is not an active reduction of energy and misses most of the advantages of torpor. Studies on hibernation to visit other planets could offer new potential applications for patient care on Earth.
Animals hibernate to survive periods of cold and food or water scarcity, reducing their heart rate, breathing and other vital functions to a fraction of their normal life, while body temperature lowers close to ambient temperature. Tardigrades, frogs and reptiles are very good at it.
Lower testosterone levels seem to aid long hibernation in mammals, estrogens in humans strongly regulate energy metabolism.
With the crew at rest for long periods, artificial intelligence will come into play during anomalies and emergencies.
The possibilities of hibernation for medical use is of particular interest to the European research community and could transform how we approach many severe illnesses.
Inducing torpor is already used in some medical environments such as surgical theathers to replace anesthesia in those patients allergic to anesthetic drugs.

Makes sense! Thank you for sharing your research, ESA! Keep up the good work & keep advancing European space flight!
Our pleasure!
I could hibernate naturally, all winter I could sleep like a bear. No problem. Work keeps me awake!
This is a fantastic and very informative video. It’s brilliant that through this research, lives might be improved here on earth.
Glad you enjoyed it!
Crazy that fiction is slowly becoming reality each day. Can't wait to see what the future holds for humanity
Estas pesquisas científicas ...são muito interessantes!! Implicam a possibilidade de viajar ...Os astronautas colocados em vida suspensa!! Interessante também e muitas respostas vêem da natureza e dos animais, ex: submarinos, sonar, iluminação, electricidade, bussolas ..é mesmo uma variedade de contributos que é sempre estimulante as respostas que podemos alcançar!!
Good research.. thanks for the information
Could we use the new discovery using tardigrad protein to protect cells in tuper thus facilitating hibernation or suspended animation.i read about the protein research from them in mice using such to protect there cells they were successful. Could it be used for research to this end.also a long shot of sharks in that live 500plus years longest animal life no answers why.
DUE ORIENTATION AND PHYSICAL EXCHANGE BETWEEN PLANETS
NECESSARY AND MUST SPACE WALK AFTER THE TRAINING
Amazing content.
Glad you enjoyed it
Go ESA!
👀 let’s see what this is about!
Brilliant! As a Biology undergraduate, I hope to do research on hibernation someday. I thought hibernation was one of those far fetched concepts that only exists in sci fi but seeing actual research being done on such a topic made me so happy. Thank you ESA for bringing us one step closer to the future we deserve among the stars…✨🪐🚀
Our pleasure, Eren! ☺

is this like cold hibernation where people are cryogenically frozen or warm hibernation more like an artificial coma? also wouldnt problems like radiation and bone deterioration still apply to hibernating people, especially if they are not frozen?
ESA scientists, which have nothing to do with n4z! scientists, say it's fine.
1. if their hibernating you can probably shield them allot better since they'll be in the same spot for the 8 months. Lead hibernation coffins or a protective EM field.
2. Yes, though most animals that hibernate do not experience atrophy, so if we can figure out the mechanism that makes that possible we could apply it to humans, both on and off earth.
Nerualink is the key to this in the next few years when they start human trials later this year
When will it be experimented on humans for long time travel?
Could it be used to live longer when terminally ill?
they'll be doing human hibernation experiments on earth for a long time first.
This form of hibernation is likely going to be a very straining process, it would not likely be possible for those already near death. Also hibernation does not stop the progression of illnesses.
@@jimpickins7900 Have they already tested long time hibernation on humans and I mean a human hibernated for 9 months straight? Never heard about it.
Maybe an evolution of that could help terminally ill to overcome increasing period of pain when maybe euthanasia is not yet advised or still needed.
"Each astrounaut need 30kg consumables per day" what are you talking?
indeed humans are too expensive to simply maintain
we better hibernate as many of us as we can here on sarth too, thus
they don't know 😂😅
ESA ☄️✨🚀🪐 YOU'RE CONTENTS ARE AWESOME👍👏😊AND VERY INTERESTING.... 💙to watch
Thank you for watching!
