It sounds very strange to do something that only animals do and to be able to travel to the red planet. We could travel to Mars without trying to do what other animals do, only the costs could be high, the health of the astronauts could not be at the maximum level and many things could make the mission difficult. 

What are other animals doing and could we copy this from them to get to Mars? Simple, astronauts going to Mars should hibernate. It sounds weird indeed, but it can greatly reduce the cost of an expedition to Mars, and the health of astronauts will be at a very high level, even maximum. First, if astronauts hibernated, they would need less food. Even if a trip to Mars takes about 260-290 days with a human crew, space agencies must put food onboard for all astronauts for 2 years (two-way trip + bonus). 

"We are talking about 30 kg per astronaut a day, and in addition, we need to consider radiation as well as mental and physiological challenges," said Jennifer Ngo-Anh, coordinator of ESA Research and Human and Robotic Exploration. the authors of the paper linking biology to engineering. "Sleepiness during hibernation is an induced condition that reduces an organism's metabolic rate. 

"This "suspended animation"is a common mechanism in animals that want to conserve energy." said ESA (European Space Agency). But how much could space agencies save on costs and supplies if astronauts hibernated? If astronauts hibernated and reduced their metabolism rate to 25% of their normal state, they could reduce supplies by about the same percentage. 

"Where there's life, there's stress," Jennifer recalls. "The strategy would minimize the boredom, loneliness and levels of aggression associated with being locked in a spaceship," she added.

"The very specific and different balance of hormones in females or males and their role in regulating metabolism suggest that women could be preferred candidates," adds Alexander.

According to ESA, scientists suggest that engineers put some kind of soft-shell pods with fine-tuned beds. It must be high humidity and temperatures below 10 degrees Celsius. But wide enough for astronauts to move. "Portable sensors would measure their posture, temperature and heart rate," says ESA. Capsules will also need to have water containers around them to protect astronauts from radiation. 

"Hibernation will actually help protect people from the harmful effects of radiation during deep space travel. Away from Earth's magnetic field, damage caused by high-energy particles can result in cell death, radiation sickness or cancer, "says Alexander. 

"Besides monitoring power consumption and autonomous operations, the onboard computers will maintain optimal performance of the spacecraft until the crew could be woken up," explains Alexander.
