First humans to travel to planet Mars in hibernation state…. find out how!

141007123531-01-mars-hibernate-horizontal-galleryAnother milestone study done for NASA foresees astronauts to travel to Mars in unconscious state with their metabolism switched into slow motion. Six astronauts lie motionless in a row of compartments with medical monitoring cables connected to their bodies, as their space ship cuts through the silent blackness that separates Earth from Mars.

This is how it works:
The space travelers are sound asleep and will be asleep for the extent of their six-month trip to Mars from Earth, having been placed in an artificially induced state of hibernation called torpor.

141007123605-05-mars-hibernate-horizontal-galleryMedical advances have made stasis possible via a method called therapeutic hypothermia. It renders the patient unconscious by lowering the body temperature. But doctors usually induce it for only three or four days at a time, not the 180 days it would take for astronauts to get to Mars from Earth, nor the 180 it would take to get back to Earth.

The two-week torpor periods would be straddled, so that there is always one astronaut who is awake for a brief period.

The colleague currently awake could check in on the other ones who are still unconscious to make sure their intravenous feeding tubes are clear, and urine removal systems and so on are working properly.

Then after two or three days, he wakes up the next astronaut by activating a heating system that brings his or her body temperature up to normal.

Then the awakened astronaut straps the other into the hibernation module, hooks up the medical systems and inserts a body cooling tube through a nostril. Heating pads behind the astronaut make sure the nasal tube doesn’t cool down their body too much.

A temperature drop of only about five degrees Fahrenheit is necessary — from 98.6 to about 93 degrees.

The habitat unit housing the sleepers would rotate to create centrifugal force simulating gravity. That would help to mitigate the reduction in bone density that naturally occurs in zero gravity.

141007123556-04-mars-hibernate-horizontal-galleryThey can be stacked up in small habitats; with minimal metabolism, they don’t need as much food, no daily change of clothes. Exercise equipment is replaced by electrodes that stimulate their muscles while they’re asleep.

That saves lots of space and altogether more than half the weight of the fully equipped rocket that it would take to transport a crew that was not sleeping through the voyage in torpor.

After six weeks of travel to Mars, the astronauts would face a 500-day mission on the barren Mars planet’s surface. Then they’d have to endure another 180 days in the cramped rocket to get home to Earth. Therapeutic hypothermia would also allow space agencies to pack more astronauts into one ship. That’s vital to meeting an often-mentioned possible ultimate goal for travel to Mars!
