Mars mission astronauts might deep sleep their way to Mars in hibernation chambers TomoNews
Getting to Mars from Earth takes a long timeâ€¦ as long as 200 days. A group of scientists funded by NASA think astronauts could pass most of that time by hibernating in a sleep chamber, much like what you see here. Each chamber is outfitted with tubes that lower thebody's temperature as well as provide nutrition. An intranasal cooling system would lower the astronaut'stemperature by 5 to 10 degrees Fahrenheit, which significantly reduces metabolism. The astronaut is fed via catheters attachedto the thigh or chest, while another tube carries waste away.
This result is what's called a torporinducedstate using therapeutic hypothermia. One concern is muscles atrophy due to lack of use. Scientists think they can address thisthrough neuromuscular electrical stimulation. As the astronauts approach Mars,the wakeup cycle begins. Warming pads slowly raise the body's temperature. It takes roughly one hour for every 1 degree rise in body temperature. Fully awake after their long nap,the astronauts are ready to begin their Mars mission.
