Can humans hibernate their way to Mars?

Scientists are trying to recreate the biology that lets animals survive months without food or water, in hopes of making deep-space travel possible Long-term space travel is bad for your health. Very bad. Being in space exposes humans to dangerously high levels of radiation; extended exposure to microgravity can damage a range of organ systems, including muscles, bones and eyes.
Living for months or years in tight quarters can have severe psychological effects. The key to solving these problems could be a 250m-year-old physiological strategy that allows mammals, birds, fish and other animals to survive extreme scarcity by essentially going offline: hibernation.
When they hibernate, animals almost completely switch off their bodily functions; they don’t eat, drink or move, and just as importantly, aren’t hungry, or thirsty and don’t seem to suffer from the cold. This remarkable ability could prove crucial in helping humans get to Mars and beyond – and could also help save lives on Earth.
